実験手順

In a reaction vessel having a cooler, a stirrer and a nitrogen introducing tube, 343 parts of adduct of bis-phenol A and 2 moles of ethylene oxide, 166 parts of iso-phthalic acid and 2 parts of dibutyl phthalate are put, and reacted for 8 hours at 230° C. under an ordinal pressure, and further reacted for 5 hours under a reduced pressure of from 10 to 15 mmHg (from 1.33 to 1.99 Pa) and then cooled by 110° C. Then 17 parts of isoborondiisocyanate was added in toluene and reacted for 5 hours at 110° C., and the solvent was removed. Thus Urethane-modified Polyester 1 was obtained, which has a weight average molecular weight of 72.000 and a free isocyanate content of 0.7%. Besides, 570 parts of adduct of bis-phenol A and 2 moles of ethylene oxide and 217 parts of terephthalic acid were condensed-polymerized for 6 hours at 230° C. in a manner similar to the above-mentioned. Thus unmodified Polyester 1 with a number average molecular weight of 2.400, a hydroxide group value of 51 and an acid value of 5. In 2,000 parts of ethyl acetate, 200 parts of Urethane-modified Polyester 1 and 800 parts of Polyester 1 were dissolved and mixed to obtain Resin Solution 1. The Tg of the resin component in the Resin Solution 1 was 64° C.
