Case 1-10939/+/A Canada Liquid dye preparations, a process for their manufacture and their use Abstract of the Disclosure Stable concentrated liquid preparations of metal complex dyes are provided. These preparations contain (1) a metal complex dye,(2)a non-ionic compound havqng a hydrotropic action and 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 Image 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, R1 is hydrogen or methyl, A is -0- or -?-0-, 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, and (5) water, a water-soluble organic - 1 - solvent having a boiling point of at least 80°C or a mixture of the two and (6) optionally conventional formulating agents. The preparations have a good stability on storage over a broad temperature range and can be diluted with water and/or organic solvents without precipitating the dye or producing other inhomogeneities. The preparations are useful for preparing padding liquors, dye baths printing pastes and 6pray solutions. - 1a -
