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.

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.

The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.

Adhesives comprising as binder an aqueous dispersion of a polymer formed from free-radically polymerizable compounds (monomers), wherein from 0.1 to 20% by weight of the monomers, based on the overall amount of the monomers, are ethylenically unsaturated acids at least 20 mol % of whose acid groups are present as a salt of at least divalent metals.

Metal salt crosslinked adhesives

A device for producing disperse mixtures by ultrasound, containing a housing, and a reaction chamber within the housing and at least one sonotrode having a free emitting surface which is directly in effective connection with the reaction chamber and whose end remote from the free emitting surface is coupled to an ultrasonic transducer, wherein the sonotrode is designed as a rod-shaped, axially emitting longitudinal oscillator with the emitting surface corresponding essentially to the surface of the reaction chamber, and wherein the reaction chamber depth which is essentially vertical with respect to the emitting surface is lower than a maximum effective depth of the sonotrode.
