<p>A re-releasable adhesive agent comprises a radiation-reactive polymer and a radiation polymerization initiator, the radiation-reactive polymer has a side chain derived from at least one monomer expressed by the formula (1): CH 2 =CR 1 COOR 2 (1), where R 1 is a hydrogen atom or a methyl group, and R 2 is a C 6 or higher alkyl group, and a side chain having one carbon-carbon double bond, and the monomer of formula (1) is contained in a ratio of less than 50 mol% with respect to the total monomer constituting the main chain of the radiation-reactive polymer.</p> |
