Abstract:
1. A radiation-curable coating composition comprising (A) at least one compound having at least two (meth)acrylate groups which is selected from the group consisting of polyester(meth)acrylate, polyether(meth)acrylate, polycarbonate(meth)acrylate, epoxide(meth)acrylate, and urethane(meth)acrylate, (B) optionally, at least one compound having at least one ethylenically unsaturated group, different than (A), (C) divinyl adipate, (D) optionally, at least one solvent, (E) at least one photoinitiator, and (F) optionally, further typical coatings ingredients, wherein the fraction of divinyl adipate (C) as a proportion of the total of the radiation-curable ingredients (A)+(B)+(C) is at least 25% by weight, wherein the epoxide(meth)acrylate is the reaction product of (meth)acrylic acid with a member selected from the group consisting of bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, 1,4-butanediol diglycidyl ether, 1,6 hexanediol diglycidyl ether, trimethylolpropane triglycidyl ether, pentaerythritol tetraglycidyl ether, 1,1,2,2-tetrakis[4-(2,3-epoxypropoxy)-phenyl]ethane (CAS No. [27043-37-4]), diglycidyl ether of polypropylene glycol (α,ω-bis(2,3-epoxypropoxy)poly(oxypropylene) (CAS No. [16096-30-3]) and of hydrogenated bisphenol A (2,2-bis[4-(2,3-epoxypropoxy)cyclohexyl]propane, CAS No. [13410-58-7]).
