Fiber-reactive phthalocyanine compound having both vinylsulfone type and

Abstract

A phthalocyanine compound represented by the following formula, ##STR1## wherein Pc is a metal-containing or metal-free phthalocyanine residue, R.sup.1 is a hydrogen atom or substituted or unsubstituted lower alkyl group, A is a substituted or unsubstituted phenylene or naphthylene group, Y is --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z, in which Z is a splittable group by the action of an alkali, W is a bridging group of the following formula, ##STR2## in which R.sup.2 and R.sup.3 are independently a hydrogen atom or a methyl or ethyl group, and n is an integer of from 2 through 6, X is a halogen atom, a is 0 or a number of not more than 2 (0.ltoreq.a.ltoreq.2), and b and c are independently a number of 1 through 3 (1.ltoreq.b.ltoreq.3, 1.ltoreq.c.ltoreq.3), provided that the total of a, b and c is not more than 4 (a+b+c.ltoreq.4), which is useful for dyeing or printing materials, particularly cellulose fiber materials, in a brilliant turquoise blue color excellent in various fastness properties.
