Document Type and Number:
WIPO Patent Application WO/2021/095649
Kind Code:
A1
Abstract:
Provided are: a resin molded article having higher abrasion resistance and improved weather resistance; a resin molded article for a vehicle window; and a method for producing a resin molded article. A rear module 1, which is a resin molded article, is constituted from: a substrate 10 made from a polycarbonate resin; a primer layer 11 made from an acrylic resin and formed on the substrate by applying a solvent and letting the solvent dry; and a hard coat layer 12 made from a silicone-based polymer and formed on the primer layer by applying a solvent and letting the solvent dry. The rear module also includes a modified layer 13 in which a hard layer is formed by irradiating and modifying the hard coat layer 12 with UV rays. The modified layer 13 is modified with high-illuminance UV light such that the modified layer 13 has a thickness of at least 70 nm, whereby a highly weather-resistant hard layer can be achieved while retaining high abrasion resistance.
