Abstract:
A composition that may be cured under the action of UV radiation and containsA) 40 to 80 parts by weight of a polyester resin component containing one or more ethylenically unsaturated polyester resins which have an acid value of 0 to 50 and a hydroxyl value of 10 to 150 and are the reaction product of a) 35 to 50 mole % of a carboxylic acid component consisting of a1) 5 to 35 mole % of a 1,2-alkenyl dicarboxylic acid monodicyclopentenyl ester, a2) 50 to 95 mole % of fumaric acid, maleic acid and/or maleic anhydride and a3) 0 to 15 mole % of a carboxylic acid and/or a carboxylic anhydride other than a1) and a2) with b) 50 to 65 mole % of an alcohol component consisting of b1) 80 to 95 mole % of a dihydric alcohol, b2) 5 to 20 mole % of a saturated monohydric alcohol and b3) 0 to 5 mole % of a trihydric alcohol, B) 20 to 60 parts by weight of a monomer component containing one or more copolymerizable monomers and C) 0.1 to 10 parts by weight of an initiator component containing one or more photoinitiators, wherein the parts by weight of A) and B) and the percentages of a) and b) each add up to 100.
