Abstract

The invention comprises disazo dyes of formula wherein R is an alkyl or aralkyl radical, R 1 and R 2 are H or CH 3 and A is an anion. The dyes are prepared by coupling 2 mols of a diazotized aminothiazole with 1 mol of an N,N1-diphenylpiperazine and treating the disazo dye obtained with at least 2 mols of an alkylating or aralkylating agent. The dyes are used to colour acrylonitrile polymer or copolymer materials in blue shades. Specification 1,051,617 is referred to.
