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.

The production of textile materials comprises a very large and complex global industry that utilises a diverse range of fibre types and creates a variety of textile products. As the great majority of such products are coloured, predominantly using aqueous dyeing processes, the coloration of textiles is a large-scale global business in which complex procedures are used to apply different types of dye to the various types of textile material. The development of such dyeing processes is the result of substantial research activity, undertaken over many decades, into the physico-chemical aspects of dye adsorption and the establishment of ‘dyeing theory’, which seeks to describe the mechanism by which dyes interact with textile fibres. Physico-Chemical Aspects of Textile Coloration provides a comprehensive treatment of the physical chemistry involved in the dyeing of the major types of natural, man-made and synthetic fibres with the principal types of dye. The book covers: fundamental aspects of the physical and chemical structure of both fibres and dyes, together with the structure and properties of water, in relation to dyeing; dyeing as an area of study as well as the terminology employed in dyeing technology and science; contemporary views of intermolecular forces and the nature of the interactions that can occur between dyes and fibres at a molecular level; fundamental principles involved in dyeing theory, as represented by the thermodynamics and kinetics of dye sorption; detailed accounts of the mechanism of dyeing that applies to cotton (and other cellulosic fibres), polyester, polyamide, wool, polyacrylonitrile and silk fibres; non-aqueous dyeing, as represented by the use of air, organic solvents and supercritical CO2 fluid as alternatives to water as application medium. The up-to-date text is supported by a large number of tables, figures and illustrations as well as footnotes and widespread use of references to published work. The book is essential reading for students, teachers, researchers and professionals involved in textile coloration.

Taking a generalized historical viewpoint of the field of chemistry and chemical technology which can be broadly defined as colour chemistry, it could be concluded that at least four distinct developments have made a significant impact on the progression and expansion of this subject area. The initiation was, of course, the discovery of the first synthetic dye, mauveine, by W. H. Perkin in 1856. This historic event ultimately resulted in the commercial development of a vast range of synthetic colorants both for textile and non-textile applications, and which possessed a more favourable cost versus benefit ratio compared to the hitherto used naturally occurring colorants. The second factor was the development over the years of synthetic fibres, an innovation which led to vigorous new research and the addition of the disperse dyes and improved cationic dyes to the extensive volume of synthetic dyestuffs enjoying successful industrial exploitation. The introduction of the fibre reactive dyes, whilst presenting innovative ideas in both the chemistry and application of colorants, may be considered as a natural development from the first event. The third development can be related to the recognition of the potential adverse effects of certain synthetic dye intermediates on human health.

This chapter discusses the principles of chromic materials as applied to textiles. The most important chromic phenomena – thermochromism, photochromism, ionochromism and electrochromism – are dealt with in individual sections, each providing a description of the physicochemical principles underlying the colour changes and a discussion of the molecular structures of the most important colorant classes. An overview of the main non-textile applications of chromic materials sets the scene for more detailed discussion of progress through ongoing research towards technical and smart textile applications. The chapter concludes with informed speculation on likely future trends in the development of products based on chromic textiles.

"Vor ungefahr zwei Jahren trat die Firma Urban & Schwarzenberg mit dem Vorschlage an mich heran, eine Enzyklopadie der technischen Chemie herauszugeben, die ungefahr 10 Bande umfassen und im Verlaufe von 3 - 4 Jahren erscheinen sollte. So wurde denn in fast 2jahriger angestrengter Vorarbeit der Grundplan fur das gesamte Werk entworfen und die Anordnung sowie der Umfang der einzelnen aufzunehmenden Artikel festgestellt. Den Gegenstand des auf breitester Basis angelegten Werkes bilden nicht nur die chemische Grossindustrie und die Metallhuttenkunde mit ihren maschinellen und apparativen Hilfsmitteln, sondern auch die zahlreichen Grenzgebiete, welche sich mit der stofflichen Veranderung oder der Veredelung der Materie uberhaupt befassen. Dem enzyklopadischen Charakter des Werkes entsprechend, musste die Anordnung des Stoffes alphabetisch sein. Doch schien es im Interesse der Ubersichtlichkeit und zur Vermeidung von Wiederholungen zweckmassig, Gebiete, welche stofflich eng zusammen gehoren, auch ausserlich aneinander zu schliessen. Um die Benutzung des Werkes in jeder nur denkbaren Weise zu erleichtern, dienen zur schnelleren Auffindung einer Substanz ausser den zahlreichen Hinweisen die jedem Bande beigegebenen sehr ausfuhrlichen Sachregister; den Schluss soll ein Generalregister bilden, welches die ganze Enzyklopadie umfassen wird. Fur die Rechtschreibung gilt durchweg die wissenschaftliche Schreibweise nach Jansen." [...] Der hier vorliegende achte Band der "Enzyklopadie der technischen Chemie" erlautert von "Natriumverbindungen" bis "Salophen" und ist mit uber 250 historischen Abbildungen illustriert. Dieses Buch ist ein unveranderter Nachdruck der Originalausgabe der zweiten neu bearbeiteten Auflage von 1931."
