ABSTRACT:
Salts of ionic dyes with compounds which contain at least one ammonium, cycloammonium or immonium group and at least one aliphatic, cycloaliphatic or carbonyl radical-substituted aromatic group or containing a piperazine or piperidine group or a heteroaromatic group selected from those of the triazine, pyrimidine, quinazoline, quinoxaline, phthalazine or phthalimidine series or which contain at least two carboxylic acid groups, at least one amino group and at least one carboxylic acid group or at least one sulfonic acid group and one aliphatic, cycloaliphatic, monocyclic aromatic or heteroaromatic group are useful for dyeing synthetic materials, particularly synthetic polyamides in the mass. The obtained dyeings have exceptionally good wet fastness.
