| 摘要 |
This invention relates to coating media based on one or more styrene-free, unsaturated polyester resins, which contain A) one or more unsaturated polyesters obtainable by the reaction of a) 0.5 to 1.0 mole of at least one alpha,beta-ethylenically unsaturated dicarboxylic acid or the anhydride thereof, b) 0 to 0.5 mole of at least one aromatic, aliphatic and/or cycloaliphatic saturated dicarboxylic acid or the anhydride thereof, c) 0.4 to 0.8 mole of at least one aliphatic saturated dihydric alcohol, d) 0.5 to 1.2 mole of at least one hydroxy-functional allyl ether, B) one or more polyglycol diacrylates of general formula where n=2-5 and m=2-5, particularly dipropylene glycol diacrylate, C) one or more initiators, and optionally one or more organic solvents, one or more pigments and/or extenders, as well as accelerators, catalysts and/or customary lacquer additives.
