Abstract
Dye preparations comprising, based in each case on the weight of the preparation, from 0.1 to 30% by weight of one or more dyes from the class of the mono- or polyazo dyes containing no acidic groups, from 0.1 to 20% by weight of a dispersant based on an arylsulfonic acid-formaldehyde condensate or from 0.1 to 20% by weight of a water-soluble dispersant based on alkoxylated phenols with or without water, and their use as inks in the inkjet process and for textile sublimation transfer printing.

A dye preparation comprising, based in each case on the weight of the preparation:
- from 0.1 to 30% by weight of one or more dyes from the class of the mono- or polyazo dyes containing no acidic groups,
- from 0.1 to 20% by weight of a water-soluble dispersant based on alkoxylated phenols having the following formula (VII) or formula (VIII), with or without water
- wherein M is an alkali metal, a is from 0 to 125 on average, b is from 37 to 250 on average, and d is 0 or 1, or mixtures thereof, and from 0.1 to 20% by weight of a polyalkylene glycol.
A dye preparation comprising, based in each case on the weight of the preparation:
- from 1 to 15% by weight of one or more dyes from the class of the mono- or polyazo dyes containing no acidic groups,
- from 0.1 to 20% by weight of a dispersant based on an arylsulfonic acid-formaldehyde condensate and containing from 3 to 50% by weight, based on the weight of the dispersant, of one or more aromatic or long-chain aliphatic carboxylic acids, salts thereof anhydrides thereof or a mixture thereof,
- from 0.1 to 30% by weight of a carbohydrate, and
- from 0.1 to 20% by weight of a polyalkylene glycol.
