PROBLEM TO BE SOLVED: To provide an active energy ray-curable pressure-sensitive adhesive for re-release, which has a small influence on an environment or a human body, can be easily handled, can largely change its pressure-sensitive adhesiveness before and after irradiation with an active energy ray, and can express high pressure-sensitive adhesiveness before the irradiation with the active energy ray and can express high releasability after the irradiation with the active energy ray.SOLUTION: The active energy ray-curable pressure-sensitive adhesive for re-release includes an active energy ray-curable polymer (P), in which the polymer (P) is obtained by causing a carboxyl group-containing polymer (A) and an oxazoline group-containing compound (B) having an oxazoline group and a radical reactive carbon-carbon double bond to react with each other. |
