摘要:
The present invention provides the discovery of an improved radiation curable coating composition comprising at least one acrylic monomer, a photoinitiator, and an ultraviolet light absorber selected from triazine or a dibenzoyl resorcinol derivative or a mixture thereof, the dibenzoyl resorcinol derivative having the formula ##STR1## where Ar and Ar' are independently substituted or unsubstituted monocyclic or polycyclic aryl groups and R' is H or a linear or branched alkyl chain having less than about 10 carbons bearing a --Si(OR.sup.2).sub.3, where R.sup.2 is a C.sub.1 to C.sub.6 alkyl group.
