Abstract

Concentrated fluid formulations of textile dyes, leather dyes or paper dyes, comprising (1) metal-free dyes, (2) non-ionic compounds having a hydrotropic action, at least one of components (3) or (4), component (3) being a reaction product of a fatty acid having 8 to 22 carbon atoms and 1 to 2 mols of diethanolamine, and component (4) being a compound of the formula ##STR1## in which R is an aliphatic hydrocarbon radical having 8 to 22 carbon atoms or a cycloaliphatic, aromatic or aliphatic-aromatic hydrocarbon radical having 10 to 22 carbon atoms, R.sub.1 is hydrogen or methyl, A is --O-- or ##STR2## X is the acid radical of an inorganic, oxygen-containing acid, the acid radical of a polybasic carboxylic acid or a carboxyalkyl radical and m is a number from 1 to 50, (5) water, a water-soluble organic solvent having a boiling point of at least 80.degree. C., or a mixture of the two, and, (6) optionally conventional formulating assistants, have excellent stability over a wide temperature range and, on dilution with water or solvents, do not form any undesired multi-phase systems or precipitates.
