Abstract: The conversion of metal-free and metalliferous polyhalophthalocyanines into a pigmentary form by treatment of the crude pigment with a sulfuric acid monophenol ester or a reaction product of a phenol which is practically inert to nuclear sulfonation under the reaction conditions with chlorosulfonic acid or oleum. The treatment mixture then has water added to it and it is stirred for cleavage at 80* to 150*C and then aqueous sulfuric acid phase is separated and the pigment is isolated after the addition of an agent having an alkaline reaction so that the phenol passes into solution.
