Abstract

The invention relates to a polymerizable, cross-linkable composition which contains: (A) 1-99.99 wt.-% of at least one conversion product of OH-functional (meth)acrylates with (i) oligomers from unsaturated rings or heterocyclic rings and maleic anhydride and/or with (ii) at least one ring-shaped polycarboxylic acid with at least 4 ring-carbon atoms and/or the anhydrides thereof with a saturated ring system, at least 4 carboxyl groups, and 0 or 1 heterocyclic ring atoms from the group N, O, S, whereby at least one carboxyl group and/or anhydride group of the above described substance groups is reacted with unsaturated polymerizable groups; (B) 0 to 98.99 wt.-% of one or more polymerizable, unsaturated organic compounds with at least one CH2═C(R10)—COO-group, whereby R10 represents H or methyl; (C) 0.01 to 5 wt.-% initiators and optional activators; (D) 0 to 90 wt.-% common solvents; (E) 10 to 90 wt.-% common fillers, pigments, thixotropy auxiliary agents, softening agents, diluting agents, rigidifying monomers, free-radical scavengers, stabilizing agents, and other auxiliary agents. The given wt.-% refers to the sum of all components (A) to (E). The composition is suited…
