Abstract

Process for the preparation of water-insoluble styryl dyes of the formula ** (See formula) ** in which A means an alkylene group, which may optionally contain an -O-acyl group, preferably an ethynyl group, B means a benzene radical or a heterocyclic radical, for example a radical of furan, thiophene, or pyridine, X means a cyano or carbalkoxy group, Y1 means hydrogen, an alkyl or alkoxy group, Y2 means a hydrogen atom, an alkyl group or an alkoxy group, Z means an alkyl or phenalkyl group or an acyloxyalkyl group, preferably a radical of the formula -A-OCO (CHp) n-1-Om-1B, m and p mean one or two and n means an integer value from 1 to 5, and where p only means 1, when n is 3, characterized in that an aldehyde free of water-soluble groups of the formula ** (See formula) ** or its aldimine, is condensed with the alkyl ester of cyanacetic acid or because one mole of a styryl derivative of the formula ** (See formula) ** in which A, X and Y1 and Y2, m and n, have the indicated significance and Z1 means an alkyl or oxyalkyl group, is acylated with one mole of a halide or anhydride of a carboxylic acid of the formula HOOC (CHp) n-1-Om-1-B and with one mole of a halide or anhydride of an aliphatic or cycloaliphatic carboxylic fiber or of an acid carboxylic acid of the formula HOOC (CHp) n-1-Om-1-B.
