Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
45 words
A photopolymerizable composition consisting essentially of 2-methoxytetrahydropyran, the diepoxide, 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate and an aryl sulfonium salt photoinitiator wherein the amount of 2-methoxytetrahydropyran present in said composition is about 5 to about 70 weight percent, based on the combined weight of said pyran and said diepoxide.
Claim 2
Dependent Claim
45 words
