Claim:
A nonaqueous coating material curable thermally or thermally and with actinic radiation, comprising (A) a hydroxyl-containing binder component comprising (A1) at least one hydroxyl-containing polyester and (A2) at least one hydroxyl-containing (meth)acrylate copolymer prepared at least partly in the presence of the polyester (A1), (B) at least one crosslinking component comprising at least one polyisocyanate and (C) at least one unbranched, hydrophobic polyester having at least two hydroxyl groups per molecule, an OH number of from 56 to 500 mg KOH/g, an acid number <10 mg KOH/g, and a number-average molecular weight (Mn) of from 300 to 2000 daltons, wherein the at least one hydroxyl-containing polyester (A1) and the hydrophobic polyester (C) are not the same and the polyester (C) has the genaral formula I [R 1 —CH(OH)—CH 2 —OOC—] 2 R (I) where R=substituted or unsubstituted divalent radical selected from the groups consisting of C 1 to C 20 alkanediyl radicals, C 2 to C 20 alkenediyl radicals, C 4 to C 12 cyclolkanediyl radicals, C 4 to C 20 alkenediyl radicals, C 6 to C 12 arylidene radicals, C 6 to C 20 arylalkyl radicals, C 6 to C 20 arylalkenyl radicals, C 6 to C 20 arylcycloalkyl radicals, C 6 to C 20 arylcycloalkenyl radicals, aliphatic radicals, cycloaliphatic radicals, acyclic or cyclic olefinically unsaturated radicals, aromatic radicals, aliphatic-aromatic radicals, cycloaliphatic-aromatic radicals, acyclic unsaturated aromatic or cyclic unsaturated aromatic radicals containing at least one carboxylic ester group, and mixtures thereof, and R 1 =a hydrogon atom or a monovalent substituted or unsubstituted radical selected fon the from the group consisting of C 1 to C 20 alkyl radicals, C 2 to C 20 alkenyl radicals, C 4 to C 12 cycloalkyl radicals, C 4 to C 12 cycloalkenyl radicals, C 6 to C 12 aryl radicals, C 6 to C 20 arylalkyl radicals, C 6 to C 20 arylalkenyl radicals, c 6 to C 20 arylcycloalkyl radicals, C 6 to C 20 arylcycloalkenyl radicals, C 6 to C 20 alkylaryl radicals, C 6 to C 20 alkenylaryl radicals, C 6 to C 20 cycloalkylaryl radicals, C 6 to C 20 cycloalkenylaryl radicals, C 6 to C 20 alkyl radicals, C 6 to C 20 cycloalkyl radicals, C 6 to C 20 alkylcycloalkenyl radicals, C 6 to C 20 alkenylcycloalkyl radicals, C 6 to C 20 alkenylcycloalkenyl radicals, C 6 to C 20 cycloalkylalkyl radicals, C 6 to C 20 cycloalkenylalkyl radicals, C 6 to C 20 cycloalkylalkenyl radicals, C 6 to C 20 cycloalkenylalkenyl radical, and mixtures thereof.
