C.I.
DefinitionThis section has been translated automatically.
The Colour Index is a reference book for all common colourants and dye-based chemicals. The C.I. is regarded as the standard work for pigment and dye chemistry and allows a definition of a colour pigment beyond the chemical structure. The Colour Index is published jointly by the British Society of Dyers and Colourists and the American Association of Textile Chemists and Colorists.
Note: Often the chemical structure of dyes with a C.I. is not publicly available due to a trade secret.
