摘要：
A polyazo compound of the following formula,
wherein X is'
-NR 2 R 3 , -OR 4 or -SR s , in which R 1 is hydrogen or alkyl, R 2 , R 3 , R 4 and R s are each hydrogen, alkyl, phenyl, naphthyl or benzyl, A is phenylene, naphthylene or alkylene, Z is a fiber-reactive group of -S0 2 CH=CH 2 or -S0 2 CH 2 CH 2 Z' in which Z' is a splittable group, Y is pyridinio, and F is polyazo dye moiety carrying a fiber-reactive group like that represented by Z, which compound is useful for dyeing or printing fiber materials to obtain a product dyed or printed in a color superior in various fastness properties with superior build-up property.
