Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A UV curable paintable composition consisting essentially of UV curable material selected from the class consisting of an acrylic monomer-polymer mixture, a polyester resin, an epoxy resin, and a polythiol-polyene resin, from 1 to 10 parts of a photoinitiator selected from the class consisting of ketones, benzoin ethers, quinones, and a cationic initiator, per 100 parts of the UV curable organic material and 0.1 to 10% by weight of the UV curable composition of a sulfonate ester of the formula, Z--SO.sub.2 --R, where Z is ##STR4## R is selected from C.sub.(6-13) aryl radicals and R 1 , R 2 , and R 3 are the same of different monovalent radicals selected from hydrogen, halogen, C.sub.(1-20) alkyl, C.sub.(1-20) alkoxy, and R radicals.
Claim 2
Dependent Claim
