Abstract:
1. A mixture curable thermally and with actinic radiation comprising (A) a binder free from carbon-carbon double bonds activatable with actinic radiation comprising at least one (meth)acrylate copolymer containing on average per molecule at least one isocyanate-reactive functional group and having a glass transition temperature Tg of from −40 to +80° C., (B) at least one polyisocyanate that is at least one of blocked and unblocked having at least one soft, flexibilizing segment, which as a constituent of three-dimensional polymeric networks lowers their glass transition temperature Tg, and (C) at least one unsaturated polyfunctional urethane that is free from isocyanate-reactive functional groups and contains on average per molecule more than four carbon-carbon double bonds activatable with actinic radiation and at least one hardening segment, the hardening segment as a constituent of three-dimensional polymer networks increasing their glass transition temperature Tg.
