The PUR dispersions that are used according to the inventive method are reactive PUR dispersions or PUR dispersions that have been subjected to a secondary cross-linking reaction.

Kits and compositions for making such dispersions are disclosed and methods for making and using the dispersions, and the components used in the dispersions are also disclosed.

The dispersions used have the advantage of being transparent.

Centrifugation of the samples is required for dispersions.

The polymer dispersions contain particles that are coded with a mixture of dyes, and the polymer dispersion particles are quantitatively determined.

Preferred milk protein dispersions are low fat.

The thus obtained aqueous dispersions are then dried.

Substances in binders and polymer dispersions

The dispersions are stabilised with surfactants.

The invention also relates to polymer dispersions which can be obtained according to said method, polymer powders produced therefrom and the use of such dispersions or polymer powders in the production of pressure-sensitive materials.

The dispersions comprise aqueous polyurethane dispersions having nanoparticles covalently incorporated into the polymer matrix.

The invention relates to an ionic dispersing agent which can be used in aqueous dispersions.

The dispersions of the present invention do not settle or coagulate prematurely.

The dispersions have improved opacity or hiding.

The invention relates to a novel method for producing polyurethane polyacrylate hybrid dispersions, to the dispersions thus obtained, and to the use thereof.
