This book has been written with the twofold purpose of serving as a guide to such students during the introductory part of their course and of supplying the needs in this field of others whose main interest is in a related branch of technology or pure chemistry.
An attempt has been made to present the main features of the subject in an easily assimilable form. The great amount of published information renders the choice of material for a short book somewhat difficult, and I am keenly conscious of topics that might be thought worthy of more extensive treatment.
However, a concise account cannot be comprehensive, and suggestions for further reading are provided at the end of the book.
The chemistry of colouring matters can be regarded as a branch of pure chemistry, but the development of knowledge in this field has followed a course determined chiefly by the applications of dyes and pigments. It has therefore appeared appropriate to treat the subject here as a branch of technology. 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. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.
The foundations of the chemical dyestuffs industry were laid in when W. Perkin discovered the dye Mauveine. At approximately the same time modern chemistry was establishing itself as a major science.
Thus, the chemistry of dyes became that branch of organic chemistry in which the early scientific theories were first used. This early eminence has now been largely lost. Dyes and Pigments: Their Structure and Properties.
Dyes and pigments are the most important colorants used to add a color or to change the color of something. They are widely used in the textile, pharmaceutical, food, cosmetics, plastics, paint, ink, … Expand. The synthesis and application of azo dyes derived from 2-Amino-1, 3,4-thiadiazolethiol on polyester fibre are described. The absorption maxima of the dyes were dependent upon the substituents in … Expand. View 1 excerpt, cites background.
Dis-azo Dyes Derived from 2-methoxynitroaniline and 3-chloroaniline and their Application on Polymer Fibres. Six disazo disperse dyes derived from 2-Methoxynitroaniline and 3-chloroaniline were synthesized in good yield. The results of the absorption spectra of the dyes show that the dyes exhibited good … Expand. Heterocyclic Dyes: Preparation, Properties, and Applications.
