A recyclable plastic article having a scratch resistant coating. An injection molded thermoplastic article is coated with a polymeric or inorganic coating so as to enable the coating to be compatible with the thermoplastic during the recycling process. The polymeric hard coat contains functional chemical groups that interact with the underlying thermoplastic resin to render the coating miscible with the thermoplastic resin when the recyclable plastic article is ground, pelletized and molded. After the typical recycling process of grinding, pelletizing, and molding, the thermoplastic resin retains at least 95% of the original mechanical properties of the virgin resin. Compatibilization agents and other processing steps are not needed to insure proper recycling.
