Abstract:
A process for the preparation of substituted amido phthalocyanines of formulaMPc--(CONR.sup.1 R.sup.2).sub.n IwhereinM is hydrogen or a metal capable of forming a metal phthalocyanine,Pc is a phthalocyanine radical,n is a number from 0.1 to 4.0,R.sup.1 is hydrogen or R.sup.3, andR.sup.2 and R.sup.3 are independently selected from the group consisting of an alkyl group having 1-20 carbons; a cyclic alkyl group; an aryl group; an arylalkyl group having from 7 to 20 carbons; a hydroxyalkyl group having from 2 to 20 carbons; an alkyl amino alkyl group or an acid salt thereof; an aliphatic aminoalkyl having from 1 to 20 carbons or an acid salt thereof; a polyoxyalkylene group of molecular weight ranging from 89 to 2000; and a polyoxyalkyleneamine of molecular weight ranging from 148 to 4000 or an acid salt thereof,via the reaction of a phthalocyanine carboxamide having the formulaMPc(CONH.sub.2).sub.x IIwherein Pc and M are as defined above, and x is a number from 0.1 to 4.0,with an amine acid salt of formula ##STR5## wherein R.sup.1 and R.sup.2 are as defined above, andZ is sulphuric acid or hydrogen chloride.
