Abstract

In a resin molded article (M), a wear-resistant surface layer (2) is provided on a surface of a base (1) made of a thermoplastic resin with an undercoat layer (3) being interposed therebetween, and the surface layer (2) has a composition containing silicon, oxygen, carbon, and hydrogen, a thickness of 0.02 μm or greater and 0.48 μm or less, and a density of greater than 1.5 g/cm³ or a hardness of 1.5 GPa or greater.

Claims

1. A resin molded article, wherein

a wear-resistant surface layer is provided on a surface of a base made of a thermoplastic resin with an undercoat layer being interposed therebetween, and

the surface layer has a composition containing silicon, oxygen, carbon, and hydrogen, a thickness of 0.02 μ

m or greater and 0.48 μ

m or less, and a density of greater than 1.5 g/cm³ or a hardness of 1.5 GPa or greater.

2. The resin molded article of claim 1, wherein

the surface layer has a composition ratio of oxygen to silicon which is greater than or equal to 1.5 and less than 2.0, and a composition ratio of carbon to silicon which is less than or equal to 0.33.

3. The resin molded article of claim 1, wherein

the surface layer is formed by plasma-enhanced CVD.

4. The resin molded article of claim 1, wherein

the resin molded article is a glazing panel for an automotive window.
