Available in PDF, EPUB and Kindle. Book excerpt: In this second edition of Natural Food Colorants two new chapters have been added and we have taken the opportunity to revise all the other chapters. Each of the original authors have brought up to date their individual contributions, involving in several cases an expansion to the text by the addition of new material. The new chapters are on the role of biotechnology in food colorant production and on safety in natural colorants, two areas which have undergone considerable change and development in the past five years. We have also persuaded the publishers to indulge in a display of colours by including illustrations of the majority of pigments of importance to the food industry. Finally we have rearranged the order of the chapters to reflect a more logical sequence. We hope this new edition will be greeted as enthusiastically as the first. It remains for us, as editors, to thank our contributors for undertaking the revisions with such thoroughness and to thank Blackie A&P for their support and considerable patience. G. A. F. R. J. D.

Download or read book Colorants for Non Textile Applications written by H.S. Freeman and published by Elsevier. This book was released on 2000-05-03 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the chemistry of natural and synthetic dyes produced for non-textile markets, where much new basic research in color chemistry is now taking place.The first group of chapters covers the design, synthesis, properties and application technology pertaining to dyes for digital printing and photography. The reader will be pleased with the breadth and depth of information presented in each case. Of particular interest is the discussion of strategies for the design of dyes in these categories, with emphasis on enhancing technical properties. In view of certain new developments, the ink-jet chapter includes results from studies pertaining to dyes for textiles.The three chapters comprising Section II of this volume cover the broad subject of dyes for food, drug and cosmetic applications and then provide an in-depth look at dyes for biomedical applications and molecular recognition. The chapter on dyes for molecular recognition places emphasis on applications in the biological sciences, including sensory materials and artificial receptors. While the former two topics have been covered elsewhere in the past, the present chapters are unequalled in scope.Section III provides an in-depth review of the design of laser dyes and dye-based functional materials. In the first of the two chapters, the major principles of laser operation are summarized. This is followed by a discussion of spectroscopic properties, such as activation and deactivation of absorbed light by laser dyes. Approaches to the development of new laser dyes are presented. The second chapter pertains to the synthesis of dicyanopyrazine-based multifunctional dyes. The visible and fluorescence spectra of these dyes in solution and the solid state are correlated with their three-dimensional molecular structures. Molecular stacking behavior and solid state properties of these "multifunctional" dye materials are presented.The final group of chapters pertains to natural dyes and dyes for natural substrates. In recent years, the impression among certain consumers that "natural" is better/safer has generated much interest in the use of natural dyes rather than synthetics. This has led to a few short discussion papers in which the environmental advantages to using natural dyes have been questioned. The initial chapter in this group provides both a historical look at natural dyes and a comprehensive compilation of natural dye structures and their sources. Though natural dyes are of interest as colorants for textiles, selected ones are used primarily in food and cosmetics.Chapter ten provides an update on the author's previous reviews of structure-color-relationships among precursors employed in the coloration of hair. Chemical constitutions characterizing hair dye structures are presented, along with a summary of available precursors and their environmental properties. Similarly, the chapter on leather dyes covers constitutions and nomenclature, in addition to providing interesting perspectives on the origin and use of leather, the dyeing of leather, and key environmental issues.This volume is concluded with another look at colors in nature. In this case, rather than revisiting colors in plant life, an interesting chapter dealing with color in the absence of colorants is presented. Chapter twelve covers basic concepts of color science and illustrates how 3-D assemblies leading to a plethora of colors are handled in nature. It is our hope that this atypical "color chemistry" chapter will invoke ideas that lead to the design of useful colorants.The chapters presented in this volume demonstrate that color chemistry still has much to offer individuals with inquiring minds who are searching for a career path. This work highlights the creativity of today's color chemists and the wide variety of interesting non-textile areas from which a career can be launched.

Download or read book Natural Colorants for Dyeing and Lake Pigments written by Jo Kirby and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "How did textile dyers manipulate the natural dyes at their disposal to obtain the colours we see on fabrics and tapestries in museum collections today? How did colour makers prepare the translucent lake pigments used by artists to give richness and volume to painted draperies and subtle modulations of colour and space in the depiction of landscape? Some of the technological factors the dyer or pigment maker could control very easily have a marked effect on the final colour: the mordant salt used on the textile fibre; the temperature at which the dye was extracted from the raw material or dyeing was carried out; the method of extracting the during pigment preparation. These factors were explored as part of a research activity within the European project CHARISMA (Cultural Heritage Advanced Research Infrastructures -- Synergy for a Multidisciplinary Approach to Conservation/Restoration), a Research Infrastructures project founded by the European Union 7th Framework Programme (2009-2014, grant agreement no. 228330). Recipes for dyeing and lake pigment making using natural dyes, based on those found in historical documentary sources, were designed to study the effects of these and other factors and used during two CHARISMA workshops held in 2011 -- one on making traditional lake pigments, the other on dyeing. This book brings together the recipes used during these very successful workshops with discussions of the historical recipes upon which they were based and is illustrated with photographs taken during the workshops. The most widely used European natural dyes are described briefly and a short account of the chemistry of dyeing and lake pigment is included. The book is aimed primarily at those who need easily modified and reproducible recipes for teaching or scientific work: conservators, scientists and teachers." -- Provided by publisher

Available in PDF, EPUB and Kindle. Book excerpt: 1.1 Prologue What is archaeomineralogy? The term has been used at least once before (Mitchell 1985), but this volume is the first publication to lay down the scientific basis and systematics for this subdiscipline. Students sometimes call an introductory archaeology course "stones and bones." Archaeomineralogy covers the stones component of this phrase. Of course, archaeology consists of a great deal more than just stones and bones. Contemporary archaeology is based on stratigraphy, geomorphology, chronometry, behavioral inferences, and a host of additional disciplines in addition to those devoted to stones and bones. To hazard a definition: archaeomineralogy is the study of the minerals and rocks used by ancient societies over space and time, as implements, orna ments, building materials, and raw materials for ceramics and other processed products. Archaeomineralogy also attempts to date, source, or otherwise char acterize an artifact or feature, or to interpret past depositional alteration of archaeological contexts. Unlike geoarchaeology, archaeomineralogy is not, and is not likely to become, a recognized subdiscipline. Practitioners of archaeomineralogy are mostly geoarchaeologists who specialize in geology and have a strong background in mineralogy or petrology (the study of the origin ofrocks).

Download or read book High Technology Applications of Organic Colorants written by P. Gregory and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional use of organic colorants is to impart color to a substrate such as textiles, paper, plastics, and leather. However, in the last five years or so organic colorants have become increasingly important in the high technology (hi-tech) industries of electronics and particularly reprographics. In some of these reprographics applications the organic colorant is used in its traditional role of imparting color to a substrate, typically paper or plastic. Examples are dyes for ink-jet printing, thermally transferable dyes for thermal transfer printing, and dyes and pigments for colored toners in photocopiers and laser printers. In other applications it is a special effect of an organic colorant that is utilized, not its color. Examples are electrical effects, such as photoconduction and the electrostatic charging of toners, both of which are essential features for the operation of photocopiers and laser printers, and the selective absorption of infrared radiation, which is utilized in optical data storage. In electronic applications the organic colorant is often employed in a device. Typical examples include liquid crystal dyes, laser dyes, electro chromic dyes, dyes for solar cells, dyes for micro color filters, and dyes for nonlinear optical applications.

Download or read book Light Absorption of Organic Colorants written by J. Fabian and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although studies on synthetic dyes have been performed for more than 100 years, their detailed elucidation requires further extensive research. The discovery of novel high polymers, the necessity of supplying a whole range of shades and increasing require ments for dyestuffs of high fastness properties give rise to a permanent search for new dyes. Extensive investigations on dyes were also occasioned by various applications in the field of spectral sensitization and of staining of biological specimens. Another more recent development concerns the lasing properties of some organic dyes. Most of the progress, however, was only achieved by time-consuming, purely empirical approaches and theoretical understanding of the dye properties is only at its very beginnings. The color is the sine qua non of every dye. For this reason organic chemists and color chemists have looked for relations between the "color and constitution" of dye molecules for a long time. This knowlege as a whole is known as "theory of color". The classic theory of color was established abou t 100 years ago by Witt and was signi ficantly extended 50 years later by W. Konig.

Download or read book Analytical Chemistry of Synthetic Colorants written by A.T. Peters and published by Springer. This book was released on 1994-10-31 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.
