To provide a re-release type adhesive which, when subjected to curing reaction caused by irradiation with radiation, shows a sufficient drop of adhesion and causes the adherend to be warped to a low level as developed by the shrinkage force caused by the curing reaction.
The present invention provides a re-release type adhesive comprising as a main component a radiation-reactive polymer having one carbon-carbon double bond and an intramolecular side chain having chain length of 6 or more in terms of the number of atoms and showing a shrinkage force of 30 MPa or less as developed by curing reaction caused by irradiation with radiation. The re-release type adhesive can be provided by reacting a polymer having a side chain including a hydroxyl group and an isocyanate compound having one carbon-carbon double bond.
