The invention relates to aqueous two-component polyurethane systems comprising vinyl polymer polyol dispersions modified with reactive diluents, to a process for preparing them and to use as coating materials.

Aqueous 2K PUR systems

The present invention relates to heat and storage stable vinyl polymer polyol secondary dispersions containing The invention also relates to a process for the preparation of the vinyl polymer polyol secondary dispersions by preparing vinyl polymer resin A) by polymerizing a mixture of ethylenically unsaturated monomers a) in the presence of an initiator b) in a water/solvent mixture and adding at least one amphiphilic polymer B), then at least partly neutralizing and dispersing the resulting product, optionally after the addition of a further amount of water.
