Physico Chemical Principles Of Color Chemistry

At the beginning of this series of volumes on Color Chemistry, the editors pointed to a number of events that have served as stimuli for techno logical advances in the field, thus preventing dyestuff manufacturing from becoming what might otherwise be viewed by now as a 'sunset industry'. The volumes which followed have provided ample evidence for our belief that the field of colour chemistry is very much alive, though arguably in need of further stimulus. For instance, a viable approach to the design of new chromophores and to the design of metal-free acid, direct, and reactive dyes having fastness properties comparable to their metallized counterparts represent the kind of breakthroughs that would help ensure the continued success of this important field. While it must be acknowledged that serendipity 'smiled' on our discipline at its inception and has repeated the favor from time to time since then, few would argue against the proposition that most of the significant advances in the technology associated with any scientific discipline result from research designed to enhance our understanding of the fundamental causes for experimental observations, many of which are pursued because they are unexpected, intriguing and intellectually stimulating. Little reflection is required for one who knows the history of the dyestuff industry to realize that this is certainly true in the colour chemistry arena, as it was basic research that led to fiber-reactive dyes, dyes for high technology, and modern synthetic organic pigments.

In the ten years since publication of the second edition of Heinrich Zollinger's "Color Chemistry", significant trends in colorant research and application have become important. Particular emphasis is given to the discussion of the synthesis, properties, and application of pigments.

Chromic phenomena, or those produced by materials which exhibit colour in response to a chemical or physical stimulus, have increasingly been at the heart of 'high-tec' developments in a variety of fields in the last decade. Many of the newer technologies, which are at the cutting edge of research, are multi-disciplinary, involving researchers from areas as diverse as physics, biology, materials science and electronic engineering. Chromic Phenomena covers five main areas: * Colour change materials, such as photochromic, thermochromic and electrochromic materials * Materials which absorb and reflect light - the classical dyes and pigments * Luminescent phenomena, including phosphorescence, fluorescence and electroluminescence * Materials which absorb light and transfer energy, eg photosensitisers, infra-red absorbers and laser-addressable compounds * Phenomena involving the manipulation of light by chemicals, such as liquid crystals, lustre pigments, optoelectronics and photonics Providing an entry point both for new researchers and for established ones, this book, with its emphasis on the technological applications of these chromic phenomena, develops and investigates new applications for colour chemistry. It will be of interest to industrialists and professionals in the biological, medicinal, electronics/telecommunications and colorant industries, as well as academics in these fields.

"Presents the most recent developments in the materials, properties, and performance characteristics of photographic, electrophotographic, electrostatic, diazo, and ink jet imaging processes. Provides current techniques and modern applications for ink jet, thermal, and toner-related imaging systems."

Textile and fibre chemistry form the theoretical basis to understand production and properties of textile based products. In this 2nd edition fundamentals of textile chemistry and theoretical and applicatory aspects of colour chemistry are interconnected to draw detailed picture of chemical reactions occurring during production and modification of textile products. An overview about chemical modification, finishing operations is given to explain how to impart special functionalities into functional products. Examples for technical scale processes and representative machinery used therein give insight into the technical reality of a dyehouse. A new chapter about circularity of textiles highlights the interlinkage between product design, including dyes and finishes, and the requirements to develop future fibre-to-fibre recycling. The work covers all relevant aspects of a textile product from fibre production, coloration, finishing, consumer use and fibre-to-fibre recycling. The content of the book allows a first entry into this multi-disciplinary field. Through its comprehensive character the authors explain the interdependence between textile and fibre processing and aspects of recycling, which makes the work a valuable source of information to design future textiles for circularity.

Key selling features: Contains an extensive list of commonly used acronyms with definitions Offers a highly readable glossary for systems and techniques Provides comprehensive information for the validation of biotechnology assays and manufacturing processes Includes a list of Log P values, water solubility, and molecular weight for selected chemicals Gives a detailed listing of protease inhibitors and cocktails, as well as a list of buffers

Chromic or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.
