Abstract
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.
