実験手順

A mixture of 64 parts of xylene and 16 parts of n-butanol was heated to 100° C. in the same flask as used in Production Example 1. To this was added dropwise a mixture of 10.2 parts of 2-ethylhexyl methacrylate, 66.8 parts of ethyl acrylate, 11.4 parts of NK ESTER M-90G, 11.6 parts of acrylic acid and 2 parts of t-butylperoxy 2-ethylhexanoate 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 t-butyl 2-ethylhexanoate 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 1.5 hours. A resin solution called Varnish E having 50.3% solids, a viscosity of 4.7 poise and a resin acid number of 90 was obtained.
