Orange red-violet, soluble, fibre-reactive, high molecular - azo dyes contg a monochlortriazine gp - for dyeing/printing natural

摘要

Title cpds. have the formula (I): (where R is H or alkyl; D is opt. substd. benzene or naphthalene residue; K is opt. substd. benzene, naphthalene or heterocyclic gp.; n is a whole no. 1-4; the SO3H gps. are linked to D and/or K and the triazinylamino gp. is linked to D or K; P is a copolymer residue of formula (II): where the mol. ratio of x:y:z is 6:0.1:1-10:3:1 and m is a whole no. 1-6). They are sol. in aq. alkali and/or water. They are prepd. e.g., by reacting an azo dye of formula: with cyanuric chloride and condensing the resulting prodt. with a copolymer PH.
