Böcker i Topics in Applied Chemistry-serien

This volume is devoted to the synthesis, application, structure, and physicochemical properties of nitroazoles (five-membered aromatic compounds). The book is unique in providing the first comprehensive treatment of nitroazoles.

Emulsification of vegetable oil-based resins was a daunting task when the author began his research, but the subsequent technology spawned a generation of stable emulsions for waterborne coatings based on vegetable oil-based alkyd resins, oils and fatty acids.

It is particularly appropriate that a volume concerned with dye chemistry should be included in the series Topics in Applied Chemistry.

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.
