Claims
- 1. A photocopolymerizable composition which, when cured is suitable for use as a pressure sensitive adhesive, comprising at least about twenty percent by weight of a polycaprolactone polyol, a cycloaliphatic monoepoxide having a vinyl substituent and a photoinitiator.
- 2. A photocopolymerizable composition as defined in claim 1 wherein the polycaprolactone polyol is a polycaprolactone diol.
- 3. A photocopolymerizable composition as defined in claim 1 wherein the polycaprolactone polyol is a polycaprolactone triol.
- 4. A photocopolymerizable composition as defined in claim 1 wherein the polycaprolactone polyol is a polycaprolactone hexol.
- 5. A photocopolymerizable composition as defined in claim 1 wherein the polycaprolactone polyol is present in said composition in an amount of about 20 to about 30 percent by weight.
- 6. A photocopolymerizable composition as defined in claim 1 wherein the cycloaliphatic monoepoxide is 4-vinylcyclohexene monoepoxide.
- 7. A photocopolymerizable composition as defined in claim 1 wherein the photoinitiator is a triarylsulfonium hexafluoro antimony salt.
- 8. A photocopolymerizable composition as defined in claim 1 wherein the photoinitiator is a triarylsulfonium hexafluoro antimony salt and the cycloaliphatic monoepoxide is 4-vinylcyclohexene monoepoxide.
- 9. The cured product of the composition defined in claim 1.
