Copper-Containing azodirect dyes are described in numerous patents and their copper imparts special properties to the dyes. Dyes containing copper are in many cases faster than related dyes which do not contain it, and moreover, most of the former are substantive. Some of these azodyes have long been on the market as Chlorantine Fast colours of the Society of Chemieal Industry in Basle and are used extensively owing to their excellent properties.　Although dyes of these types are described in the patent literature, little is generally known of their constitution and synthesis. It appears to be of interest, therefore, to study more closely their preparatiou and the relations between their constitution and properties.　The present paper describes the synthesis of the following eight azodyes and the investigation of the behavibour of copper atom in them:　Dyes I and II : 2-Aminophenol-4-sulphoic acid is each coupled with di-j-acid aud phenyl-j-acid.　Dyes III and IV : 6-Nitro-2-aminophenol-4-sulphonic acid is each coupled with di-j-acid and phenyl-j-acid.　Dyes V, VI, VII and VIII are Dyes of Dyes I, II, III and IV copperized each with ammoniacal copper sulphate.
