摘要： Provided is 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 express high releasability after the irradiation with the active energy ray. The active energy ray-curable pressure-sensitive adhesive for re-release includes an active energy ray-curable polymer (P), in which the polymer (P) includes one of a polymer obtained by causing a carboxyl group-containing polymer (P3) and an oxazoline group-containing monomer (m3) to react with each other, and a polymer obtained by causing an oxazoline group-containing polymer (P4) and a carboxyl group-containing monomer (m2) to react with each other.
