Abstract (en)
[origin: DE19600147A1] The invention relates to a process for coating objects using polymer-containing powder coatings which are applied to the surface of the substrate, melted and cross-linked by exposure to UV radiation. The polymers used are copolymers containing the following: (a) at least one monomer of general formula (I) CH2=C(R<1>)-CO-OR<2>, in which R<1> is H or CH3 and R<2> is H, CnH2n+1, n being 1-30, an alicyclic, araliphatic or heterocyclic group or hydroxyalkyl, alkoxyalkyl, glycidyl or aminoalkyl group, or of general formula (II) CH2=C(R<1>)-CO-NR<3>R<4>, in which R<1> is H or CH3, R<3> and R<4> can be identical or different and stand for H, CH2OH or CnH2n+1, n being 1-30, or CH2OR<5>, R<5> being CmH2m+1 and m being 1-12; and (b) at least one copolymerisable ethylenically unsaturated organic compound of general formula (A), in which R' and R'' can be identical or different and stand for H, CpH2p+1, p being 1-6, cycloalkyl, aryl or aralkyl and R''' stands for an acryloyl, methacryloyl, ethacryloyl or cinnamoyl group, this compound being partially replaceable by one or more other copolymerisable ethylenically unsaturated organic compounds different from (a).
