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.

Dye preparations comprising azo dyes

Dye preparations comprising, based on the weight of the preparation, from 0.1 to 30% by weight of one or more dyes selected from the class of the anthraquinones or quinophthalones which are free of ionic groups, from 0.1 to 20% by weight of a dispersant based on an arylsulfonic acid-formaldehyde condensation product, from 10 to 90% by weight of a mono- or polyhydric alcohol and optionally water, are useful as inks in the inkjet process and also for sublimation transfer printing.

Colorant preparations

Dye preparations containing azo dyes

Pigment preparation for the ink-jet process which comprises A) at least one finely divided, organic or inorganic pigment, B) a dispersant based on arylsulfonic acid/formaldehyde condensation products or an alkoxylated phenols, and C) water, as essential constituents. It provides for prints of high light fastness, wash fastness and rub fastness.

Method of ink-jet printing with pigment preparations having a dispersant

The invention provides for pigment preparations containing, as main components, A) at least a finely divided organic or inorganic pigment, B) a dispersing agent composed of formaldehyde-arylsulfonic acid or oxalkylated phenols condensates, C) a radiation curable binder, D) optionally a photoinitiator, and E) water. The invention also provides for the use of said preparations as inks for said ink jet printing method.

Dye mixtures containing polyazo dyes and CI Sulphur Black 1 dye

Liquid or solid mixtures of low-salt sulfo-containing 1:2 metal complex dyes and poly-N-vinylpyrrolidone or copolymers of N-vinylpyrrolidone and vinyl acetate are especially useful for dyeing paper and wood and also for dyeing and finishing leather and fur.

Mixtures of sulfo-containing 1:2 metal complexes with vinyl polymers

Brightener mixtures based on bisstyryl compounds

Condensates of arenesulfonic acids and formaldehyde are prepared by sulfonating arenes obtainable by thermal cracking of a naphthenic residue oil and fractional distillation of the cracked products of the fraction obtained at 100-120.degree. C. under atmospheric pressure, sulfonating this aromatics fraction with oleum at 120.degree.-160.degree. C. using an amount of from 0.7 to 1.2 parts by weight of oleum having an SO.sub.3 content of 24% by weight per part by weight of aromatics fraction, and subsequently condensing the arenesulfonic acids with formaldehyde in a conventional manner, and are used as dispersants, in particular for preparing dye formulations.
