ABSTRACT:
A method which includes enhancing effects upon treating the surface of a thermoplastic resin article by a surface-activating treatment such as corona discharge and the like or by a primer treatment and, thereby, improving coating performance, printability, adhesiveness and so forth of the thermoplastic resin article. The resin article is subjected to a surface-heating treatment which comprises heating only surface layer of the resin article up to a melting point of the thermoplastic resin or a higher temperature followed by cooling the surface layer, and then, subjected to the surface-activating treatment or primer coating.
