An acrylic copolymer resin was prepared by feeding 150 parts of toluene into a 500-ml 4-necked flask equipped with a cooling tube, stirrer, and thermometer, heating it to 110° C., adding styrene 20 parts, n-butyl methacrylate 60 parts, ethyl methacrylate 120 parts, methacrylic acid 14 parts, azoisobutyronitrile 5 parts and toluene 70 parts spending 2 hours under an inert gas atmosphere, and heating for further 6 hours. The resulting toluene solution of copolymer was found to have 50.5% of nonvolatile matter and a polymer acid value of 18.
