摘要:
The present invention relates to free-radically polymerizable, siloxane-containing urethane (meth)acrylates which comprise, in incorporated form, a) at least one compound which contains at least one active hydrogen atom and at least one free-radically polymerizable &agr;,&bgr;-ethylenically unsaturated double bond per molecule, b) at least one diisocyanate, c) at least one compound which contains two active hydrogen atoms per molecules, d) at least one compound which contains at least one active hydrogen atom and at least one siloxane group per molecule, to water-soluble or water-dispersible polymers which comprise these urethane (meth)acrylates in copolymerized form, to the use of these polymers, and to cosmetic compositions which comprise these polymers.
