Abstract
Coordinatively hexavalent complex salts of trivalent cobalt, in which four of the six coordination positions on the cobalt are occupied by the doubly negatively charged phthalocyanine ring system and the remaining two coordination positions are each occupied by an amine from the series of primary, secondary or tertiary aliphatic, aromatic or heterocyclic monoamines or polyamines and which are obtained by reaction of cobalt phthalocyanine compounds with primary, secondary or tertiary, aliphatic, aromatic or heterocyclic amine are prepared according to an improved process in that the cobalt phthalocyanine compounds used are those in which the central cobalt atom is present in the trivalent state, and which contain anions, bonded in the form of salts, from the series fluoride, chloride, bromide and iodide.
