Abstract: A polyimide resin has an acid dianhydride-derived structure and a diamine-derived structure, the acid dianhydride contains an acid dianhydride represented by the general formula (1) and a fluorine-containing aromatic acid dianhydride, and the diamine contains a fluoroalkyl-substituted benzidine. In the general formula (1), n is an integer of 1 or more, and R1 to R4 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or a perfluoroalkyl group having 1 to 20 carbon atoms. The content of the acid dianhydride represented by the general formula (1) may be 10 to 65 mol %, and the content of the fluorine-containing aromatic acid dianhydride may be 30 to 80 mol %, based on 100 mol % of the total of the acid dianhydride.

Abstract: A curable composition that contains a hydrolyzable silyl group-containing polymer and that exhibits improved adhesion to polyolefinic materials is provided. The curable composition contains (A) a hydrolyzable silyl group-containing (meth)acrylic ester polymer, (B) a chlorinated polyolefin resin, and (C) a nitrogen-containing dialkoxysilane compound. The curable composition may further contain a guanidino group-containing compound (D) or a hydrolyzable silyl group-containing polyoxyalkylene polymer (E).
