PROBLEM TO BE SOLVED: To provide a lignin resin composition excellent in curability and a molding material using the same. A resin composition comprising a lignin compound and a crosslinking agent as essential components, wherein the lignin compound has a molar ratio of phenolic hydroxyl group and alcoholic hydroxyl group obtained by decomposing biomass from 9: 1. A lignin resin composition, which is one or two selected from a lignin compound having a ratio of 8: 2 and a lignin derivative having a reactive group introduced into the lignin compound. The reactive group in the lignin derivative is a lignin resin composition having an epoxy group. A molding material comprising the lignin resin composition and a filler. [Selection figure] None |
