The invention relates to solvent-based coating compositions, comprising at least one hydroxy-functional (meth)acrylic copolymer I having an OH-value from 40 to 260 mg KOH/g, and a number average molecular mass (Mn) from 1,300 to 20,000 g/mol, which comprise the following polymerized components: A. 15 to 70 wt-%, preferably 20 to 40 wt-% of at least one polyalkyleneglycol (meth)acrylate, B. 0 to 70 wt-%, preferably 10 to 50 wt-% of at least one vinylaromatic olefinically unsaturated monomer capable of radical polymerization, C. 10 to 60 wt-%, preferably 15-40 wt-% of at least one hydroxy-functional olefinically unsaturated monomer capable of radical polymerization that is different from A, D. 0 to 60 wt-%, preferably 5-50 wt-% of at least one olefinically unsaturated monomer capable of radical polymerization that does not contain further functional groups and E. 0 to 40 wt-%, preferably 0-30 wt-% of at least one olefinically unsaturated monomer capable of radical polymerization that is different from A, B, C and D, whereby the sum of the proportions of components A to E totals 100 wt-%.
