ABSTRACT:
Phthalocyanine compounds of the general formula ##STR1## in which Pc is the radical of copper, cobalt or nickel phthalocyanine which can be substituted by chlorine or phenyl, a denotes a whole or fractional number from 1 to 3, b denotes a whole or fractional number from 1 to 3 and c denotes a whole or fractional number from zero to 2, it being possible for a, b and c to be identical or different from one another, but the total of (a+b+c) is equal to a whole or fractional number from 2 to 4, R represents a hydrogen atom or an alkyl group having 1 to 4 C atoms, A is a direct bond or a group of the general formula --(CH.sub.2).sub.m -- or --(CH.sub.2).sub.n --NH-- in which m denotes a whole number from 1 to 4 and n denotes a whole number from 2 to 6, B is the phenylene or naphthylene radical which can be substituted by alkyl having 1 to 4 C atoms, alkoxy having 1 to 4 C atoms, halogen, carboxy, sulfo, carbamoyl, sulfamoyl, alkylsulfonyl having 1 to 4 C atoms, carboalkoxy having 2 to 5 C atoms, acetylamino and nitro, D represents a direct bond or a radical of the formula --CH.sub.2 -- or --CH.sub.2 --CH.sub.2 --, Y represents the vinyl group or the .beta.-sulfatoethyl, .beta.-phosphatoethyl, .beta.-thiosulfatoethyl, .beta.-hydroxyethyl or .beta.-chloroethyl group and X is a hydrogen atom or the equivalent of a monovalent, bivalent or trivalent metal.
