Procedure

An acrylic adhesive A was prepared in the following manner. A reaction liquid containing monomers including 13 parts by weight of dodecyl methacrylate, 78 parts by weight of 2-ethylhexyl methacrylate, and 9 parts by weight of 2-ethylhexyl acrylate, and 50 parts by weight of ethyl acetate was supplied to a 40-L polymerization apparatus. Subsequently, a nitrogen atmosphere at 80° C. was maintained in the polymerization apparatus. To the reaction liquid, a polymerization initiator solution prepared by dissolving 0.5 parts by weight of benzoyl peroxide in 50 parts by weight of cyclohexane was added over 24 hours to copolymerize the above monomers. After the completion of the polymerization, ethyl acetate was further added to the reaction liquid to obtain an acrylic adhesive solution A containing 35% by weight of the acrylic adhesive A including a dodecyl methacrylate/2-ethylhexyl methacrylate/2-ethylhexyl acrylate copolymer.
