[0063] Sample 1: Making the first and third adhesive layers of epoxy
[0064] First, 100 parts by weight of cresol novolak epoxy resin (YDCN8P, commercially available from Toto Kasei Co.), 50 parts by weight of phenol novolac resin (KPH2000, commercially available from Kolon Chemical Co.), 0.02 parts by weight of 1 - a mixture of cyanoethyl-2-phenylimidazole (CURESOL 2PZ-CN, commercially available from Shikoku Kasei Co.) for 3 hours. Subsequently, 50 parts by weight of a phenoxy resin (YP50, commercially available from Toto Kasei Co.) was added to the stirred mixture, and then the mixture was further stirred for 6 hours. The resulting stirred mixture was spread on a substrate of release-treated polyethylene terephthalate film to a thickness of 38 μm. The coated film was then dried at 90° C. for 3 minutes to produce a B-staged 40 μm thick first adhesive layer and a B-staged 10 μm thick third adhesive layer.
