実験手順

A mixture of 40 parts of xylene and 40 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 65.7 parts of ethyl acrylate, 15 parts of cyclohexyl methacrylate, 19.3 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-butylperoxy 2-ethylhexanoate in 10 parts of xylene and 10 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 C having 50.0% solids, a viscosity of 6.5 poise and a resin acid number of 150 was obtained.
