(57) Abstract: The present invention has sufficient adhesiveness before irradiation with energy rays, and can significantly reduce the residue of the adhesive on the adherend after peeling after irradiation. It can be cured as much as possible, the expansion rate in the expanding process is high, and the recognition at the time of picking up is also excellent. Furthermore, in the bonding process, extremely low pick-up force can be obtained, regardless of the presence or absence of the expanding process. An object is to provide an energy ray-curable pressure-sensitive adhesive composition having high workability. An energy ray-curable pressure-sensitive adhesive composition according to the present invention is characterized by containing two or more energy ray-curable copolymers having an energy ray-polymerizable group in a side chain. . |
