The use of compounds of the general formula I in aqueous binder-containing formulations, wherein the variables are each as defined as follows:

Method for the treatment of substrates

Colorant preparations contain the following ingredients: 

Colouring preparations

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&#x3c;500 nm. 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

The invention relates to polyurethane block copolymers of general formula (I) to (IV), in which the variables are defined as follows: A represents a polyurethane block, which contains at least one hydrophilic group, B is a hydrophobic polyurethane block, X, Xare hydrophilic end groups and n is a whole number from 1 to 20. The invention also relates to the production of cross-linkable dispersion additives from the inventive polyurethane block copolymers and to the use of said cross-linkable dispersion additives for colorant preparations, in particular inks for ink-jet printing.

Cross-linkable polyurethane block copolymers and their use in dispersion binding agent systems

Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.

Method for producing polymer coated pigment particles by precipitation

Dye-containing polymer particles of at least one dye in a matrix of an essentially water-insoluble polymer and having an average particle size within the range from 5 nm to 5 &#x3bc;m are prepared by a process which comprises precipitating the dye-containing polymer particles from a solution of the polymer and of the dye in a water-miscible organic solvent by addition of an aqueous phase thereto.

Polymer particles containing dye

The invention relates to a heat-insulating coating which comprises one or more cholesteric IR-reflecting layers and to processes for its preparation and to its use.

Thermal insulating coating

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

Method for coating substrates

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.

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.

Sheet-like structures obtainable by thermal curing and having a crosslinked cholesteric liquid crystalline ordered structure are suitable, for example, for decorative coatings, for producing security marks, pigmentary particles, polarizers, color filters and IR reflectors.
