Procedure
252 g of Adeka Resin EP-4100, 16 g of PGE (phenyl glycidyl ether), 70 g of toluene and 70 g of IPA were added to 132 g of DEAPA and the addition reaction was carried out at 80° to 90° C. for 4 h while the solvent was refluxed. Then, toluene and IPA were distilled out. After thorough distillation of the solvent, a reaction product (A-2) was obtained. This reaction product was mixed with the phenoic novolac (B-1) obtained in Example 1 or bisphenol F in a ratio shown in the following table and a melt masking reaction was carried out at 150° C. for 3 h.
