Some Relations between the Chemical Constitution of Cibacron Dyes and their Dyeing Characteristics

The early history of the reactive dyes and the requirements for practical application are discussed. The structural elements of Cibacron reactive dyes are indicated, and the dyeing properties of such dyes of the azo, anthraquinone and phthalocyanine groups are correlated with their chemical constitution. Reference is made to the advantage of using a special detergent for washing off reactive dyeings produced with phthalocyanine derivatives.
