Versuchsvorschrift

360.0 g of methyl ethyl ketone was charged in a 2 litter three-necked flask equipped with a stirrer, a thermometer, a reflux cooling tube, and a nitrogen gas introduction tube, and the temperature was elevated to 75° C. Then, while keeping the temperature inside the flask at 75° C., a solution mixture of 180.0 g of phenoxyethyl acrylate, 162.0 g of methyl methacrylate, 18.0 g of acrylic acid, 72 g of methyl ethyl ketone, and 1.44 g of “V-601” (manufactured by Wako Pure Chemical Industries, Ltd.) was dropped at a constant speed so as to complete dropping in 2 hr. After completion of the dropping, a solution of 0.72 g of “V-601” and 36.0 g of methyl ethyl ketone was added, stirred at 75° C. for 2 hr and then, a solution of 0.72 g of “V-601” and 36.0 g of isopropanol was further added and stirred at 75° C. for 2 hr. Then, the temperature was elevated to 85° C. and stirring was continued for further 2 hr, thereby obtaining a resin solution of phenoxyethyl acrylate/methyl methacrylate/acrylic acid (=50/45/5 [mass ratio]) copolymer.
