Resin article having a ceramics coating layer

#1. Field of the Invention

#The present invention relates to a resin article having a coating layer made of ceramics.

#2. Description of the Prior Art

#The resin article having the ceramics coating layer according to the present invention comprises a resin substrate shaped in a form such as a plate, a ceramics coating layer formed by a physical coating method, and an intermediate layer between the substrate and coating layer. The intermediate layer is made of a resin which has a higher hardness than that of the resin forming the substrate.

#The resin substrate in this description designates a molded body made of a thermoplastic resin or a thermosetting resin. The resin article may be formed in a regular shape such as a plate which can be determined according to the usage. Such resins as polymethyl acrylate, ABS, polyvinylchloride, nylon and polyester may be employed.

#The ceramics coating layer is a thin ceramics which is formed by a conventional physical vapor deposition. Such physical deposition methods are available as vacuum evaporation, sputtering, reactive vacuum evaporation and reactive sputtering. The ceramics coating layer may be such a conductive transparent one as indium tin oxide composed of indium oxide including tin oxide for 5%. Also such ceramics coating layer may be made of titanium nitride, aluminium nitride, silicon oxide and titanium oxide.
