Estimating the term…
An object of this invention is to provide a molded resin product having atmosphere of a quality product as a result of a stereoscopic pattern that is formed on the container surfaces by a simple method such as coating or vapor deposition. Another object of this invention is to provide a surface treatment process for laying a stereoscopic pattern of high quality on the resin surfaces. The molded resin product of this invention comprises a substrate made of a transparent resin, opaque coating film disposed on rear surface of the substrate except for an area set aside for a patterned portion, a transparent resin material disposed in the area set aside for the patterned portion on the rear surface of the substrate, and an opaque reflection coating or a half-reflective coating laminated to the transparent resin material. Under this configuration of the molded resin product of this invention, the patterned portion looks as if it pops up from the rear surface of the substrate. If a half-reflective coating is used, the pattern is visible through the half-reflective coating when the pattern is viewed from the rear surface of the lid of a molded resin product, thus giving atmosphere of high quality to the container.
A molded resin product comprising a substrate made of a transparent resin, opaque coating film disposed on a rear surface of the substrate except for an area set aside for a patterned portion, a transparent resin material disposed on the rear surface of the substrate in the area set aside for the patterned portion, and an opaque reflection coating or a half-reflective coating disposed on a rear surface of the transparent resin material.
A process for surface treatment of a molded resin product wherein opaque coating film is disposed on a rear surface of a substrate made of a transparent resin, except for an area set aside for a patterned portion, that a transparent resin material is disposed on the rear surface of the substrate in the area set aside for the patterned portion, and that an opaque reflection coating or a half-reflective coating is disposed on a rear surface of the transparent resin material, so that a stereoscopic pattern or patterns is/are formed on an upper surface of the substrate.
