Abstract

Vat dyestuffs are made by treating iron, nickel, or cobalt phthalocyanines insoluble in aqueous alkali metal hydroxide solutions at elevated temperatures and in presence of a diluent liquid at the reaction temperature with phosgene, oxalyl chloride, or sulphuryl chloride under such conditions as to time and temperature that, after saponifying introduced acid chloride groups, the dyestuffs have become vattable in alkaline hyposulphite solution, but remain substantially insoluble in aqueous alkali metal hydroxide solutions. The products contain one carboxylic group to 1-4 mols. phthalocyanine, or one sulpho group to 2-120 mols. The phthalocyanines may contain non-solubilizing substituents such as methyl, ethyl, propyl, hydroxyethyl, halogen, amino, nitro, and aryl. The products probably contain acid chloride groups which may be saponified in the vat or specially with alkali metal hydroxide solutions. They dye cotton blue shades from the vat. Examples describe the above reactions conducted in an aluminium chloride-sodium chloride melt or in trichlorbenzene. Specifications 496,970 and 510,901 are referred to.
