- (a) from 40 to 60% by weight of at least one (meth)acrylate monomer having a glass transition temperature from −60 to 120° C.;
- (b) from 10 to 70% by weight of at least one acrylamide compound;
- (c) from 20 to 60% by weight of at least one (meth)acrylate oligomer having a glass transition temperature from −80 to 60° C.;
- and
- (d) from 3 to 5% by weight of at least one photoinitiator;
- and
- (e) from 0.05 to 0.5% by weight of at least one fluorescent brightener selected from the group consisting of benzoxazole derivatives, bis-benzoxazoles;
- bis-benzoxazolyl-stilbenes;
- bis-benzoxazolyl-thiophenes, thiophenediyl benzoxazoles, 2,5-thiophenediylbis-(5-tert-butyl-1,3-benzoxazoles);
