PURPOSE: To improve heat resistance, solvent resistance, water resistance or the like by containing annular olefin resin with a silicon compound residue containing a hydrolytic group, and a photo-reactive substance to generate a bridged compound via reaction with the resin.
CONSTITUTION: In annular olefin resin (A) having a hydrolytic silicon group, a photo-reaction substance (B) to generate a bridged compound due to reaction with the resin (A) upon exposure to an activated beam, and a sensitizer and other additives as necessary are evenly dispersed. The (B) component is preferably 1 to 20 pts.wt. for the (A) component. The (A) component is resin having a silicon compound residue containing a hydrolytic group inside a molecular chain, at a side chain or at the end of a chain, and a number average molecular weight is between 5000 and 20000 (GPC analysis value using cyclohexane as solvent). Also, the resin preferably has a silicon content between 0.05 and 10% on the basis of polymer weight. Furthermore, an aromatic bisdiazo compound, optical diamine generating agent or the like can be mentioned as the (B) component.
