Relevant academic research and scientific papers

Dyes of the 1-sulfo-5-(2'-amino or 2'-substituted amino-4'-fluoro-5-triazin-6'-yl-aminomethyl)-naphthyl-2-azo series

Dyes of the formula STR1 wherein K is the radical of a coupling component which can additionally contain azo groups, R is hydrogen or methyl, and Z is a fluorine atom, a substituted or unsubstituted amino group, a substituted or unsubstituted hydroxyl group, a substituted or unsubstituted mercapto group, or a substituted or unsubstituted hydrocarbon radical are distinguished by high reactivity and they produce dyeings of good wet- and light-fastness properties. The dyes of the Formula (I) are suitable for dyeing and printing a very wide variety of materials, such as silk, leather, wool, polyamide and polyurethane fibres, and especially cellulosic materials of fibrous structure, such as liner, cellulose, regenerated cellulose, and in particular cotton. They are suitable both for the exhaust method and for dyeing by the pad-dyeing process. They are also suitable for printing, in particular on cotton.

2-Amino-1-sulfonaphthalene containing acylaminomethyl substituent

Azo reactive dyestuffs which in the acid form correspond to the formula STR1 wherein R denotes hydrogen or lower alkyl, W denotes a direct bond or a bridge member, Z denotes a reactive group and A denotes the radical of a coupling component, and their use for the dyeing and printing of materials containing hydroxyl groups or amide groups as well as for the wash-fast dyeing and printing of natural or regenerated cellulose.
