The present invention relates to coating compositions, which are curable by radiation and contain I) 0 to 95 parts by weight of at least one binder curable by radiation and containing maleate, fumarate and/or acryloyl groups other than those of component II), II) 5 to 100 parts by weight of a mixture of A) 20 to 80 parts by weight of at least one polyester resin prepared from fatty acids, provided that at least 20 wt.% of component A) is a fatty acid having a number average molecular weight of 112 to 400 and B) 20 to 80 parts by weight of compounds containing (meth)acryloyl groups, having a viscosity at 23°C of 10 to 1,000 mPa.s and having a number average molecular weight of 170 to 1,000, wherein the sum of the parts by weight of components I) and II) adds up to 100, based on the weight of components I) and II), and the sum of the parts by weight of components A) and B) adds up to 100, based on the weight of components A) and B).
Compositions de revêtement photoréticulables renfermant I) 0 à 95 parties en poids d'au moins un liant photoréticulable contenant du maléate, du fumarate et (ou) des groupes acryloyle autres que ceux du constituant II), II) 5 à 100 parties en poids d'un mélange de A) 20 à 80 parties en poids d'au moins une résine de polyester préparée à partir d'acides gras, à la condition qu'au moins 20 % en poids du constituant A) soit un acide gras ayant une masse moléculaire moyenne de 112 à 400, et de B) 20 à 80 parties en poids de composés renfermant des groupes (méth)acryloyle, possédant une viscosité de 10 à 1000 mPa.s à 23 °C et une masse moléculaire moyenne de 170 à 1000; la somme des parties en poids des constituants I) et II) donne 100, en prenant comme base la masse des constituants I) et II); la somme des parties en poids des constituants A) et B) donne 100, en prenant comme base la masse des constituants A) et B).
