Abstract
A transparent resin plate superior in quality and productivity and a method for producing the same by forming a hard-coat layer on a substrate into a hardened film and by establishing a reforming method thereof are disclosed. The transparent resin plate has a substrate (1), a primer layer (2) and a hard-coating layer (3) in order, wherein the primer layer (2) is formed by a wet method, the hard-coating layer (3) is formed out of silicone polymer by the wet method, the surface of the silicone polymer layer is exposed to irradiation by ultraviolet light having a wavelength less than 200 nm, and only the exposed region is changed into a reformed region mainly composed of silicon dioxide.
Claims10
A method for producing a transparent resin plate in which a resin substrate is covered with a hard-coat layer, comprising:
- forming said hard-coat layer out of silicone polymer by a wet method;
- irradiating a region of the hard-coat layer with vacuum ultraviolet rays from an ultraviolet light source, wherein the vacuum ultraviolet layers have a wavelength less than 200 nm, and wherein only said region is reformed, by exposure to the irradiation, into a hardened film mainly composed of silicon dioxide, said region having a thickness no greater than 0.6 μm and being thinner than the portion of the hard-coat layer that is other than said region.
A transparent resin plate comprising:
- a hard-coat layer for covering a transparent resin plate, wherein the hard-coat layer comprises silicone polymer, and a part of a surface of the hard-coat layer comprises a hardened film having a film thickness no greater than 0.6 μm and being mainly composed of silicon dioxide, the hardened film forming a flat surface with the part of the silicone polymer that is not the hardened film.
