Zusammenfassung:	PURPOSE:To improve mold releasability of moldings using a phenolic resin from a heated metallic mold. CONSTITUTION:The objective phenolic resin composition is obtained by blending 100 pts.wt. phenolic resin with 0.1-100 pts.wt. terpenic resin and/or rosin-based resin oil resin or further 0.1-100 pts.wt. coumarone-indene resin and/or petroleum resin. This resin composition is excellent in mold releasability. Thereby, the mold releasability of moldings from a heated metallic mold can be improved without losing thermosetting properties of the phenolic resin and deteriorating physical properties such as strength after the molding by a prescribed extent or more. As a result, the operation to mold a blended material using this composition is facilitated.
