Abstract

Cationic dyestuffs, which dye polyacrylonitrile modified by acids, or copolymers thereof and also polyamides and polyesters blue/red - blue/green shades fast to light, heat, washing, and dry-cleaning have the formula:- (where the gp. is a thiazole ring opt. substd. in pros 4 and/or 5 or a benzthiazole ring opt. substd. in pos 6. B is an indolyl gp of formula in which R1 is 1-4C alkyl or aralkyl or aryl gp. opt. contg. a 1-2C or alkoxy gp. halogen cyano or nitro gp R2 is H. 1-4C alkyl or alkoxyalkyl, acyloxyalkyl haloalkyl, cyanoalkyl, carbamoylalkyl or an aniline gp. of formula in which R3 is H 1-2C alkyl or alkoxy, halogen, cyano or nitro R4 and R5 are each 1-4C alkyl or alkoxyalkyl, acyloxyalkyl, cycloalkyl, aralkyl or aryl opt contg. a 1-2C alkyl or alkoxy gp halogen cyano or nitro gp. n is a whole no 1-2 when B is indolyl R is H, CH3 halomethyl or 1-4C alkoxy and ehn B is anilino R is 1-4C alkoxy Z is an anion).
