Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a composition useful for producing a polymeric ion- conductive film excellent in mechanical characteristics, and having a good adhesion force and a high ionic conductivity at an ambient temperature by using a specific crosslinking agent and plasticizer. SOLUTION: The composition for producing a polymeric ion-conductive film, contains (A) 1-50wt.% alkali salt expressed by A B (A is a cation such as lithium, sodium, etc.; B is an anion such as Cl and Br ) based on the total weight of the composition, (B) 0.1-20wt.% photo-setting initiator, (C) 1-60wt.% an acrylate and/or methacrylate of a polyethylene glycol alkyl ether expressed by formula I [R is H or a 1-20C alkyl; (m) is 200-1000], (D) 1-60wt.% crosslinking agent expressed by formula II [R is R or formula III; (n) is 1-10] based on the weight of the component (C) and (E) 1-50wt.% vinyl-based monomer expressed by formula IV (R is phenyl or formula V).
