Abstract: The resin composition of the present invention comprises (A) a cycloolefin resin selected from the group consisting of a random copolymer of a cycloolefin prepared from a specified cycloolefin such as norbornene or tetracyclododecene, a (co)polymer obtained by a ring-opening polymerization of such a cycloolefin and a product of hydrogenation of the above ring-opening (co)polymer; and(B) an oligomer having an allcyclic structure and/or an aromatic ring structure, e.g., a terpene resin oligomer. Therefore, the resin composition of the present invention is especially excellent in coating and bonding suitabilities.
