Information on colouring materials

Dye manufacturers provide dyers with detailed descriptions of their dyes, regarding their application and behaviour in normal use, in the so called “Color Card or Shade Card”. The most comprehensive reference on dyes and colouring material is the colour Index, first published by the Society of Dyers and Colorists (SDC) of England in 1924. The third edition published jointly with American Association of Textile Chemists and Colourist (AATCC). The information includes physical properties, chemical constitution, method of application, fastness properties, and list of potential fibres to which they can apply.
