PURPOSE:To provide the titled film excellent in anchorability between an insulated film and an adhesive layer, storability, etc., by providing two adhesive layers, upper and lower, each comprising a compsn. in which a particular crosslinker is incorporated with an acrylic copolymer on the film. CONSTITUTION:An acrylic copolymer is prepd. which comprises 40-80wt% monomer of formula I , 15-50wt% acrylonitrile, and 1-25wt% monomer of formula II. A lower adhesive layer comprising a compsn. in which 1-10pts.wt. diisocyanate of formula III and/or triisocyanate of formula IV is incorporated with 100pts.wt. said copolymer as a crosslinker is provided on an insulated film. Then, an upper adhesive layer comprising a compsn. in which 0.1-10pts.wt. monomer of formula V as a crosslinker is incorporated with 100pts.wt. said copolymer is provided on the film. Thereafter, 1-20pts.wt. alkyl-etherified melamine and 0.1-10pts.wt. polyol of formula VI, based on 100pts.wt. said copolymer respectively, are incorporated in either one of the both layers as crosslinking agent.
