Versuchsvorschrift

A mixture of 64 parts of xyylene 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 20.0 parts of isobutyl acrylate, 50.9 parts of ethyl acrylate, 14.1 parts of acrylic acid, 15.0 parts of NK ESTER M-90G and 3 parts of t-butylperoxy 2-ethylhexanoate at a constant rate over 4 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 16 parts of xylene and 4 parts of n-butanole 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 F having 50.0% solids, a viscosity of 7.5 poise and a resin acid number of 110 was obtained.
