Procedimiento

Methyl ethyl ketone was added to a composition comprising 45 parts by weight of a bisphenol A epoxy resin (epoxy equivalent weight: 190, trade name: EPIKOTE 828 produced by Yuka Shell Epoxy Co., Ltd.) and 15 parts by weight of a cresol novolac epoxy resin (epoxy equivalent weight: 195, trade name: ESCN 195 produced by Sumitomo Chemical Co., Ltd.) as epoxy resins, 40 parts by weight of a phenol novolac resin (trade name: PLYORPHEN LF2882 produced by Dainippon Ink & Chemicals, Inc.) as a hardener for the epoxy resins and 0.7 parts by weight of γ-glycidoxypropyltrimethoxysilane (trade name: NUCA-187 produced by Nippon Yunicar Kabushiki Kaisha) as a silane coupling agent and mixed with stirring. To the mixture were added 150 parts by weight of an epoxidized acrylic copolymer having a glycidyl methacrylate or glycidyl acrylate unit content of 2 to 6 wt. % (weight average molecular weight: 1,000,000, trade name: HTR-860P-3 produced by Teikoku Kagaku Sangyo Co., Ltd.) and 4 parts by weight of an amine-epoxy adduct (trade name: AMICURE MY-24 produced by Ajinomoto Co., Inc.) as a curing accelerator, and the mixture was stirred with an agitating motor for 30 minutes, to obtain a varnish. A 75 μm-thick coating of a B-stage state was formed from the varnish, to produce an adhesive film bearing a carrier film (a release treated polyethyleneterephthalate film, thickness: 75 μm) (drying conditions: temperature: 140° C., time: 5 minutes). In the adhesive of the B-stage state, AMICURE MY-24 was dissolved uniformly in the mixture of the epoxy resins and hardener, but was not dissolved in the acrylic rubber and was deposited as particles. After the complete curing of the adhesive, the epoxy resins and the acrylic rubber were separated into a disperse phase and a continuous phase, respectively.
