Abstract

1,186,753. Basic disazo dyes. SUMITOMO CHEMICAL CO. Ltd. 11 July, 1967 [16 July, 1966; 28 July, 1966], No. 31765/67. Heading C4P. 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,N<SP>1</SP>-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.
