APPENDIX
1. A curable re-release adhesive comprising a radiation-
reactive polymer comprising a main chain and a plurality of
intramolecular side chains, each side chain having a terminal
carbon-carbon double bond, a chain length of 6 or more in terms
of number of atoms, and the same or a different number of atoms
as each other side chain in the polymer; and said re-release
adhesive having a shrinkage force of 30 Mpa or less as developed
upon curing with radiation,
wherein said side chains are introduced into the radiation-
reactive polymer by a method comprising copolymerizing a monomer
containing a reactive functional group (a) with a comonomer to
synthesize a polymer having the functional group (a) in its side
chains, and then reacting the polymer having the functional
group (a) with a compound having a functional group (b) that is
reactive with the functional group (a) and one carbon-carbon
double bond while maintaining the carbon-carbon double bond,
such that the terminal carbon-carbon double bond of each
side chain of the radiation-reactive polymer is the only carbon-
carbon double bond of each side chain.
2. The curable re-release adhesive as claimed in claim 1,
which further comprises a radiation-reactive oligomer in an
amount of 0.1 to 150 parts by weight per 100 parts by weight of
said radiation-reactive polymer.
3. A re-release adhesive sheet comprising a substrate film
and an adhesive layer comprising a curable re-release adhesive
provided on one surface of the substrate film, said re-release
adhesive comprising a radiation-reactive polymer comprising a
