Abstract
An actinic radiation-reactive pressure-sensitive adhesive composition can be cured in air at a high speed, without irritation and bad smell, and comprises 1 a pressure-sensitive adhesive organic compound, and 2 an actinic radiation-curable resin comprising (1) one or more polythiol compounds and (2) one or more polyene compounds each having at least two actinic radiation-reactive carbon-to-carbon double bonds in the molecule.
Claims4
An actinic radiation-reactive pressure-sensitive adhesive composition having an essential components:
- a pressure-sensitive adhesive organic compound comprising an acrylate copolymer, and
- an actinic radiation-curable resin comprising one or more polythiol compounds and one or more polyene compounds, said polyene compounds each having at least two actinic radiation-reactive carbon-to-carbon double bonds derived from a substituted or unsubstituted allyl alcohol and the equivalent ratio of carbon-to-carbon double bonds to the thiol groups being between 0.7:1.0 and 1.5:1.0, said composition having a reduced adhesion strength after curing.
