(57) [Abstract] [Purpose] As a material suitable for coating polycarbonates and polyolefins containing cyclo rings, it has excellent scratch resistance, adhesion, stain resistance, high surface hardness, and a relatively wide range of physical properties. A silica-based coating material that can be adjusted. [Structure] A silane coupling agent used in the pretreatment, and an alkoxysilane hydrolyzate, a fluorine-based polymer, an inorganic oxide and an inorganic polyacid derivative used after the treatment. |
