Abstract

A resin article having a ceramics coating layer comprises a resin substrate, an intermediate layer and a ceramics coating layer. The intermediate layer is made of a crosslinked resin having a higher hardness than that of the resin substrate. The intermediate layer acts to increase the bonding strength between the resin substrate and the coating layer so that the durability against the peeling of the coating layer can be improved.

Claims

1. A resin article having a ceramics coating layer thereon, said article comprising:

a resin substrate formed in an uniform shape,

an intermediate layer made of a cross-linked acrylate having a hardness greater than said resin substrate at least partially covering the surface of said resin substrate, and

a ceramics coating layer formed on the surface of said intermediate layer.

2. The resin article according to claim 1, in which the intermediate layer is harder than said resin by at least 1 pencil hardness.

3. The resin article according to claim 1, in which the resin substrate is made of a thermoplastic resin or a thermosetting resin.

4. The resin article according to claim 3, in which the thermoplastic resin is a polycarbonate, polymethylmethacrylate, or ABS.

5. The resin article according to claim 1 in which the ceramic coating layer is indium tin oxide.
