ABSTRACT:
Curable compositions comprising (a) a fluorine- or silicon-containing copolymer, (b) a (meth)acrylic copolymer and (c) at least one curing agent are described, each of the two copolymers comprising functional groups which can react with the curing agent, wherein the fluorine- or silicon-containing copolymer comprises a UV absorber which is chemically bound by reaction with the free reactive groups of the copolymer. These copolymer compositions can be used as paint binders.
