Abstract
Modified zirconia fine particles which are stable in an acidic region as well as in an alkaline region, and which may be readily adjusted in refractive index in a predetermined range are disclosed. Also disclosed is a substrate with a hard coat film excellent in adhesiveness with the substrate, abrasion resistance, scratch strength, pencil hardness and the like without interference fringes and a coating solution which may form the hard coat film. The substrate with a hard coat film is composed of composite oxide particles formed on at least one surface of the substrate and a matrix component, wherein the composite oxide particles are composite oxide particles having a core-shell structure composed of a core formed from zirconium oxide and a shell formed from antimony pentoxide and/or silica.
