Abstract

Sulphur dyestuffs of the phthalocyanine series are made by reacting phthalocyanines or their metal complex salts with chlorosulphonic acid and hydroxylamine, hydroxylamine salts or primary omega-nitroparaffins having a chain length of less than 4 carbon atoms in the presence of a compound of an element of Group Va or VIa of the Periodic Table, at a temperature in the range of 70-150 DEG C. to form polyaminophthalocyanines which are reacted, without being isolated, in the same temperature range with at least 5 mols of sulphur monochloride per mol of polyaminophthalocyanine. Examples are given.
