The publisher Asia Pacific Business Press Inc. has published “The Complete book on Natural Dyes & Pigments” to share the knowledge. NIIR Board of Consultants & Engineers has carefully written this book for the people who want to make their career in the field of dye and chemicals.

The book covers all the major topics on dye and pigment, which tells that pigment and dye are two different things. Molecule of a dye is soluble in any solvent and absorbs light at visible wavelengths, whereas, molecule of a pigment is colouring matter that can be dissolved in water or oil to make paint. In comparison to pigment, dyes are higher in number and have high product resistance. In fact, dyes impart the colors by selective absorption, at the same time, in pigments it is either by selective absorption or scattering of light.

Ommochrome is a kind of biological pigment, which found in plants as well as animals. The book describes the technology and method that manufacture various materials, such as plastic, cosmetic and rubber. Cyanine dyes are non-synthetic name of a dye, which belongs to the group of polymethine. This dye is very useful and can be combined with various other dyes especially in biomedical imaging, such as fluorescent dye. You will get to know about such combinations through this book.         

Because of environmental problem, the industries of synthetic dye and pigments are rapidly moving towards the natural dye and pigment. Therefore, the book informs about the basic gist of introduction, properties, uses and benefits of various kinds of dye and pigments. This of course, helps the people, who are new in the industry as well as update the knowledge of the existing professionals. Experts of the field never feel shy to increase the knowledge on the various parts of their field. In fact, the specialization in the field makes the person grow in the right direction with right knowledge.    

The book throws the light on various topics related dye and pigment, which includes ommochromes, distribution of ommochromes, isolation and purification of ommatins, structure, black pigments, animal pigments, plant pigments, azo dyes, dyestuffs, cyanine dyes, fluorescent brightening agents, optical whitening agents,  pyrimidine pigments : the pterins, red pigment from geniposidic acid and amino compound, materials and methods, the relationship between the evolution of carbon dioxide, evaluation of pigment, results and discussion and much more.

Considering the use of technocrats, institutional libraries, entrepreneurs, new and existing industrial author writes the book with the hope of finding it useful. You can browse our link http://www.niir.org/books/book/complete-book-on-natural-dyes-pigments/isbn-8178330326/zb,,ee,a,0,0,a/index.html.
