The present invention is a surface that is excellent in reactivity with an organic silicon compound or resin that is a matrix component of a coating film and can exhibit excellent coating performance by being blended with a coating material for forming a coating film. The object is to provide treated fine particles. On the surface of the inorganic oxide fine particles, the following formula (1) R n M 1 (OR ') zn (1) M 1 : one or more elements selected from Si, Ti, Zr, and Al R, R ′: one or more groups selected from an alkyl group having 1 to 8 carbon atoms, an aryl group, or a vinyl group n: 0 An oligomer modified fine particle obtained by modifying an oligomer derived from a metal alkoxide represented by an integer z: valence of M 1 , wherein the degree of polymerization of the oligomer is 3 or more, and the oligomer An oligomer-modified fine particle having a weight average molecular weight of 1,000 to 10,000. |
