Abstract

The present invention is a process for producing an injection-molded thermoplastic work piece having a thermoset coating bonded thereto, comprising the steps of introducing into a closed mold a thermoplastic material, such as a polyolefin, heated to a temperature above its melting point and molding said material to form a work piece; followed by introducing a thermoset coating composition capable of generating free radicals into the closed mold to contact at least a portion of a surface of the work piece, the temperature of which is at or above the temperature at which free radicals contained in the coating composition are generated. The mold is then opened and the work piece is removed after the coating composition has at least partially cured. The present invention is also directed to a molded article made by the described process.
