Phthalocyanine fiber reactive compound

A method for producing a phthalocyanine compound represented by a free acid of the following formula (I), ##STR57## wherein Pc is a metal-free or matal-containing phthalocyanine residue, W is a group of ##STR58## in which R' and R" are independently a hydrogen atom or a methyl or ethyl group, and n is an integer of from 2 to 6, R is an unsubstituted or substituted lower alkyl group, A is an unsubstituted or substituted phenylene or naphthylene group, Y is a group of --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z in which Z is a group capable of being split by the action of an alkali, a is a positive number of from 1 to 3, and b and c are independently a positive number of from 0 to 3, provided that a, b and c satisfy 0<a+b+c.ltoreq.4, which comprises (1) reacting a phthalocyanine sulfochloride with a diamine compound selected from piperazine and alkylenediamines of the following formula (II), ##STR59## wherein R', and R" and n are as defined above, in the presence or absence of ammonia, to obtain a compound of the following formula (III), ##STR60## wherein Pc, W, a, b and c are as defined above, and then reacting cyanuric chloride with the compound of the formula (III) and an aromatic amine of the following formula (IV), ##STR61## wherein R, A and Y are as defined above, in an optional order, or (2) reacting cyanuric chloride with the diamine compound as defined above and the aromatic amine of the formula (IV) in an optional order to obtain a triazine compound of the following formula (V), ##STR62## wherein W, R, A and Y are as defined above, and then reacting the triazine compound of the formula (V) with a phthalocyanine sulfochloride in the presence or absence of ammonia.
