PROBLEM TO BE SOLVED: To provide a curable resin material-particulate composite material capable of flexibly responding to changes in an organic resin material, a manufacturing method thereof, an optical material comprising a resin-particulate composite obtained by curing the material, and a light emitting device using the same. To provide. First, the surface of fine particles made of a material having a high refractive index is treated with at least a first surface treatment agent R 1 X 1 and a second surface treatment agent R 2 X 2 . R 1 is a long-chain aliphatic or alicyclic hydrocarbon group that prevents fine particles from aggregating and may have a substituent. R 2 is a hydrocarbon group having a structure that is compatible with at least a portion of the resin material monomer and capable of being polymerized together with the resin material when cured, or a derivative group thereof. X 1 and X 2 are —COOH, —PH (O) (OH), —PO (OH) 2 , —SO (OH), —SO 2 (OH), —SH, —NH 2 , or —CH═. it is CH 2. Next, the fine particles and the uncured or semi-cured resin material are mixed with a polymerization agent or the like as necessary. [Selection] Figure 1 |
