Abstract

The invention comprises water-soluble azo dyes of the formula <FORM:1089145/C4-C5/1> wherein X is H, alkyl, alkoxy or acylamino, Y is H, alkyl, alkoxy or SO3H, R is H, alkyl or substituted alkyl and n is 1 or 2. They may be obtained by reacting an azo dye of the formula <FORM:1089145/C4-C5/2> with diketene with acetoacetylation of the amino group. Examples are given for the production of the dyes. They are useful for dyeing or printing natural or synthetic polyamide textile materials.
