摘要

Process for the production of water-insoluble azo dyes on textile material of cellulose fibers or proteins, characterized by treating the textile material in an alkaline bath containing an azo component and a diazoamino compound of the formula **(See formula)** where they are: R is a phenyl, halogenophenyl, alkylphenyl, alkoxyphenyl, dialkylphenyl, alkyl halogenophenyl, alkoxyhalogenophenyl, alkylcarbamylphenyl, alkoxycarbamylphenyl, alkylsulfamylphenyl, alkoxy-alkylaryl-alkylaryl-alkylaryl-alkylaryl-phenyl, alkyl-alkylaryl-phenyl, alkyl-alkylaryl-phenyl, alkyl-alkylaryl (alkyl- or aralkyl-sulfonyl) phenyl or acylaminophenyl, Alk a lower straight-chain or branched-alkyl moiety, and R1 a carboxyalkyl, sulfoalkyl or sulfophenyl moiety optionally bearing a halogen atom or an alkyl group a wetting or dispersing agent as well as possibly an inorganic salt, and then, by treatment with acidic media at less than 40ºC, the formation of dye is caused.
