process for the preparation pepapation dyeing liquid and its application

摘要

Stable concentrated liquid preparations of metal complex dyes are provided. These preparations contain (1) a metal complex dye, (2) a non-ionic compound having 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 -O- or IMAGE 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 solvent having a boiling point of at least 80 DEG 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 spray solutions.
