Described herein is a dicarboxylic acid compound of formula (I): Wherein: Rcomprises an aryl group, Ris an alkylene group comprising 1 to 6 carbon atoms, n is 0 or 1, Ris H or CH, and X is S or NZ, wherein Z is H, an alkyl group comprising 1 to 4 carbon atoms or a phenyl group. Such compounds can be used to modify the surface of inorganic particles. These modified inorganic particles may then be advantageously used in polymerizable resins to increase the refractive index of the resulting composite, while enabling good flow properties of the polymerizable composition.
