Dyestuff preparations

Abstract

The present invention provides dye preparations comprising, each percentage being based on the weight of the preparation, a) from 0.1% to 30% by weight of one or more anthraquinone, quinophthalone or azo dyes which are free of ionic groups as a component (A), b) from 0.1% to 20% by weight of a dispersant based on a naphthalenesulfonic acid-formaldehyde condensation product having an average molecular weight of at least 11 000 g/mol, as a component (B), c) from 0.1% to 90% by weight of one or more mono- or polyhydric alcohols as a component (C), d) from 0% to 5% by weight of customary assistants as a component (D), and e) optionally water ad 100% by weight.

1 . A dye preparation comprising, each percentage being based on the weight of the preparation, 
 a) from 0.1% to 30% by weight of one or more anthraquinone, quinophthalone or azo dyes which are free of ionic groups as a component (A),    b) from 0.1% to 20% by weight of a dispersant consisting of a naphthalenesulfonic acid-formaldehyde condensation product having an average molecular weight of at least 11 000 g/mol, as a component (B),    c) from 0.1% to 90% by weight of one or more mono- or polyhydric alcohols as a component (C),    d) from 0% to 5% by weight of customary assistants as a component (D), and    e) if appropriate water ad 100% by weight.
