Claim 1
Independent Claim
140 words
An ultraviolet curable coating composition consisting essentially of about 20 to about 100 percent by weight, based on the total curable composition, of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing at least two vinyl polymerizable groups per molecule, up to about 60 percent by weight, on the same basis, of an alpha beta ethylenically unsaturated compound containing a single polymerizable alpha beta ethylenically unsaturated group, about 0.05 to about 15 percent by weight, on the same basis, of an ultraviolet photoinitiator, about 0.1 to about 5.0 percent by weight, on the same basis, of poly(phenylene sulfide), and about 0.05 up to about 0.1 percent by weight, on the same basis, of a triplet state sensitizer having a triplet state energy in the range of about 40 to about 60 k cal/mole selected from Eosin-Y, pyrene, fluorescein and trans-stilbene.
Claim 2
Dependent Claim
