[0314] Synthesis of Unsaturated Group-Containing First Resin A
[0315] 182 g of propylene glycol monomethyl ether hexanoate was introduced into a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen gas introduction tube, and after replacing the atmosphere in the flask with air, the temperature was raised to 100° C., and then The following solution was added dropwise to the flask through the dropping funnel for 2 hours, that is, to the flask containing 47.2 g (0.40 moles) of vinyl toluene, 43.0 g (0.50 moles) of methacrylic acid, 2-hydroxypropyl dehydroabietic acid acrylate [Bimset 101 manufactured by Arakawa Chemical Co., Ltd.] A solution of 3.6 g of azobisisobutyronitrile was added to a mixture of 44.5 g (0.10 mol) and 136 g of propylene glycol monomethyl ether acetate, and the stirring was continued at 100°C 5 hours. Next, after replacing the atmosphere in the flask from nitrogen to air, 30 g [0.20 mol] of glycidyl acrylate ...

[0320] Synthesis of Unsaturated Group-Containing Second Resin C
[0321] 182 g of propylene glycol monomethyl ether hexanoate was introduced into a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen gas introduction tube, and after replacing the atmosphere in the flask with air, the temperature was raised to 70° C., and then Add the following solution dropwise to the flask through the dropping funnel in 2 hours, that is, to the flask containing 60.0 g (0.25 moles) of methacrylic acid, 4-epoxy tricyclo [5.2.1.02.6] decyl acrylate ( [5.2.1.02.6] ) 240.0 g [0.75 mol (mixture of compounds represented by formula 11 and formula 26 in a molar ratio of 50:50)] and 136 g of propylene glycol monomethyl ether acetate added 3.6 g of azobisisobutyronitrile solution, and continued to stir at 70°C for another 4 hours. Thus, the unsaturated group-containing first resin D having a solid content acid value of 110 mgkOH / g was obtained. The...
