Claims
- 1. A polymerizable composition comprising a photoinitiator and a compound having the formula ##STR23## wherein A is selected from the group consisting of lower alkyl and R'HC.dbd.CHOR--; R and R" are each independently a divalent radical having from 2 to 20 carbon atoms and are selected from the group of alkylene, mono- or poly-alkoxylated alkylene, alkenylene, alkynylene, arylene, alkarylene and aralkylene radicals, which radicals are optionally substituted with halo, alkyl, cyano, nitro or alkoxy; R' is hydrogen or lower alkyl; (n) has a value of from 1 to 10 and (m) has a value of from 0 to 10; with the proviso that R" contains at least 3 carbon atoms when m is zero.
- 2. The composition of claim 1 wherein the composition contains a cationic photoinitiator.
- 3. The composition of claim 2 wherein the composition contains up to 75% of a acrylate or methacrylate compound.
- 4. The composition of claim 3 wherein the photoinitiator is a mixture of a cationic and a free radical photoinitiator.
- 5. The cured product obtained by the process which comprises applying to a substrate an effective protective coating of the composition of claim 1 and curing said coating on said substrate by exposure to an effective curing amount of radiation.
- 6. The cured product obtained by the process which comprises applying to a substrate an effective protective coating of the composition of claim 4 and curing said coating on said substrate by exposure to an effective curing amount of radiation.
