Abstract:
1. A UV-A-curable, solvent-containing composition comprising (A) 1% to 50% by weight of at least one UV A curable constituent selected from the group consisting of monomers (a1) comprising at least three UV A-curable reactive functional groups and at least one isocyanate-reactive functional group and mixtures (a2) of monomers (a21) that are free from isocyanate-reactive functional groups and comprise at least two UV-A-curable reactive functional groups, and monomers (a22) that comprise at least two UV A curable reactive functional groups and at least one isocyanate-reactive functional group; (B) 0.01% to 10% by weight of at least one colorless or substantially colorless photoinitiator having at least one absorption wavelength maximum of 300 to 400 nanometers; (C) 10% to 70% by weight of at least one alkyl and/or cycloalkyl acetate having 3 to 10 carbon atoms in the alkyl radical and/or in the cycloalkyl radical; (D) 10 to 70% by weight of at least one alkoxyalkyl, alkoxycycloalkyl, cycloalkoxyalkyl and/or cycloalkoxycycloalkyl acetate; (E) 0.001% to 5% by weight of at least one constituent that lowers the interfacial tension; and (F) 0 to 50% by weight of at least one alkylaromatic having at least two alkyl radicals having 1 to 6 carbon atoms in the molecule.
