A nonaqueous coating material curable thermally or thermally and with actinic radiation, comprising n (A) a hydroxyl-containing binder component comprising n (A1) at least one hydroxyl-containing polyester and n (A2) at least one hydroxyl-containing (meth)acrylate copolymer prepared at least partly in the presence of the polyester (A1) n (B) at least one crosslinking component comprising at least one polyisocyanate, and n (C) at least one low molecular mass and/or oligomeric, essentially unbranched, hydrophobic polyester having at least two hydroxyl groups in the 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; n process for its preparation, and its use. |
