Versuchsvorschrift

A mixture of 50 parts of xylene and 50 parts of n-butanol was heated to 100° C. in the same flask as used in Production Example 1. To this ws added dropwise a mixture of 45.6 parts of ethyl acrylate, 32.5 parts of methyl methacrylate, 10.3 parts of 2-hydroxyethyl acrylate, 11.6 parts of acrylic acid and 1.5 parts of t-butylperoxy 2-ethylhexanoate at a constant rate over 3 hours. After the addition, the reaction mixture was kept at the same temperature for 2 hours. A resin solution called Varnish H having 49.8% solids, a viscosity of 12.9 poise and a resin acid number of 90 was obtained.
