ENERGY-RAY-CROSSLINKABLE ADHESIVE AGENT COMPOSITION, CROSSLINKED ADHESIVE AGENT, ADHESIVE SHEET, AND PRODUCTION METHODS THEREFOR

Abstract: an energy-ray-crosslinkable pressure-sensitive adhesive composition containing an acrylic polymer having energy ray crosslinkability, and another acrylic polymer that is substantially free of radical-reactive unsaturated double bonds and has a weight-average molecular weight (mw) of 280000 or less. the energy-ray-crosslinkable pressure-sensitive adhesive composition is included in a pressure-sensitive adhesive sheet and a crosslinked pressure-sensitive adhesive obtained by crosslinking the energy-ray-crosslinkable pressure-sensitive adhesive composition with an energy ray. a method for producing the crosslinked pressure-sensitive adhesive, a method for producing the crosslinked pressure-sensitive adhesive, and a method for producing the pressure-sensitive adhesive sheet are also provided.
