Pigment preparations comprising alkoxylated polyethylenimine

The invention relates to colorant preparations containing the following main constituents: A) at least one dispersed (A1) or dissolved (A2) colorant; B) if a colorant corresponding to (A1) is used, a dispersing agent; C) a low-molecular polytetrahydurofurane (C1), optionally mixed with one or more difficult-to-evaporate, water-soluble or water-miscible organic solvents (C2); and D) water.

Colorant preparations

Azoxy dyes and their Cu complexes

The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter <500 nm. The present invention also relates to perylene dyes of the formula III as set forth in claim 35. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.

Method for producing aqueous polymer dispersions containing colorants

Dispersant

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 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

Dye mixtures comprising one or more thienyl- and/or thiazole-azo dyes with a coupling component of the aminothiazole, aniline or tetrahydroquinoline series, one or more dyes of the class of the monoazo or disazo dyes, methine dyes, azamethine dyes, anthraquinone dyes, nitro dyes or quinophthalone dyes which have their respective absorption maximum at a wavelength of from 410 to 520 nm and optionally one or more dyes of the class of the monoazo or disazo dyes, methine dyes, azamethine dyes, anthraquinone dyes, nitro dyes or quinophthalone dyes which have their respective absorption maximum at a wavelength of from 600 to 700 nm, the FWHM value of the absorption maximum being at least 2000 cm,, are useful for thermal transfer and for dyeing or printing synthetic materials.

Dye mixtures containing thienyl and/or thiazolazo dyes

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.
