Abstract

The invention relates to a curable polyurethane polymer which comprises in copolymerized form PA1 A) from 40 to 80% by weight, based on the overall weight of components A) to F), of at least one hydroxyl-containing prepolymer having at least one free-radically or photochemically polymerizable .alpha.,.beta.-ethylenically unsaturated double bond, PA1 B) from 0.1 to 20% by weight, based on the overall weight of components A) to F), of at least one compound having at least one isocyanate-reactive hydroxyl group and/or primary or Secondary amino group and, in addition, at least one polar functional group, PA1 C) from 0.1 to 10% by weight, based on the overall weight of components A) to F), of at least one compound selected from diamines, polyamines and mixtures thereof, PA1 D) from 0 to 20% by weight, based on the overall weight of components A) to F), of at least one further compound other than A), B), C) and E), having at least two isocyanate-reactive groups, which are hydroxyl groups and mixtures of hydroxyl groups and/or primary or secondary amino groups, PA1 E) from 0 to 20% by weight, based on the overall weight of components A) to F), of at least one compound having an isocyanat…
