실험 절차

A mixture of 64 parts of xylene and 16 parts of n-butanol was heated to 90° C. in the same flask as used in Production Example 1. To this was added dropwise a mixture of 25.0 parts of isobutyl methacrylate, 33.0 parts of ethyl acrylate, 22.7 parts of methyl methacrylate, 19.3 parts of acrylic acid and 2 parts of azobisisobutyronitrile at a constant rate over 3 hours. After the addition, the mixture was kept at the same temperature for 30 minutes. Then a solution of 0.2 parts of azobisisobutyronitrile in 16 parts of xylene and 4 parts of n-butanol was added dropwise at a constant rate over 30 minutes. Thereafter the reaction mixture was kept at the same temperature for 2 hours. A resin solution called Varnish D having 49.5% solids, a viscosity of 7.8 poise and a resin acid number of 150 was obtained.
