Abstract

1,184,825. Azo dyes. CASSELLA FARBWERKE MAINKUR A.G. 25 May, 1967 [26 May, 1966; 22 Nov., 1966; 21 March, 1967 (2)], No. 24436/67. Heading C4P. Water-insoluble azo dyes containing cyano groups are obtained by reacting a mono- or dis-azo dye free of water-solubilizing groups, which contains at least one halogen atom directly linked to an aryl or hetero-aryl nucleus, with CuCN or a mixture of a cuprous compound and an alkali metal cyanide or alkaline earth metal cyanide in an inert organic solvent, using at least one equivalent of cyanide. Reference has been directed by the Comptroller to Specification 1,125,683.
