Procedure
A reflux condenser, a thermometer, a bleed tube, and a stirrer were set to a four-necked flask. In order to prepare a reaction solution, 212 parts by mass of cresol novolac epoxy resin (N-695 (item number) available from DIC Corporation, epoxy equivalent weight: 212), 221 parts by mass of diethylene glycol monoethyl ether acetate, 0.2 parts by mass of hydroquinone, 300 parts by mass of ω-carboxy-polycaprolactone monoacrylate (Aronix M-5300 (trade name) available from TOAGOSEI CO., LTD., the number average molecular weight: 290), and 3 parts by mass of triphenyl phosphine were added to the four-necked flask. The reaction solution was heated at 115° C. for 12 hours with air bubbled therein to cause the addition reaction. Subsequently, into thus-obtained solution in the four-necked flask, 76 parts by mass of tetrahydrophthalic acid anhydride and 97.3 parts by mass of diethylene glycol monoethyl ether acetate were added, and then thus-obtained solution was heated at 110° C. for 5 hours to react them. Consequently, a 65 mass % solution (carboxyl group containing resin solution C-2) of resin containing a carboxyl group was obtained.
