About Colour Index

Colour Index Online

Colorants are listed in the Colour Index according to the widely acclaimed system of Colour Index Generic Names and Colour Index Constitution Numbers. A detailed record of products available on the market is presented under each Colour Index reference. Against each product name is listed the manufacturer, physical form, principal usages and comments supplied by the manufacturer to guide prospective customers. The new format has been devised after thorough consultation with the coloration industry (such as major manufacturers, users, ETAD and CPMA) so that it includes the sort of information that a user needs to have for his day-to-day work.

It is published on the web in two parts as follows:

Part 1 covers pigments and solvent dyes, widely used in the paint, plastics, ink and other coloration industries.

Part 2 covers dye classes used in a very wide range of industries. The main dye classes are: acid, basic, direct, disperse, food, fluorescent brightener, mordant, reactive, sulphur and vat, plus several other classes of minor or historical importance.

You can subscribe to Part 1, Part 2 or the Full Edition (Parts 1 and 2).
