Provided are a cardanol-modified silane coupling agent, which can improve strength and toughness by improving adhesion at an interface between a filler and a cellulose resin when being used as a surface-treatment agent, a resin additive, or the like, a cardanol-modified filler subjected to a surface treatment with the cardanol-modified silane coupling agent, and a cellulose resin composition having excellent toughness. More specifically, provided are a cardanol-modified silane coupling agent obtained by reacting cardanol or a derivative thereof with an epoxy silane coupling agent or an isocyanate silane coupling agent, a cardanol-modified filler obtained by subjecting a filler to a surface treatment with the cardanol-modified silane coupling agent, a cellulose resin composition comprising the cardanol-modified filler and a cellulose resin, and a cellulose resin composition comprising the cardanol-modified silane coupling agent, a filler, and a cellulose resin. |
