Abstract
Polymer compositions containing a polyoxymethylene polymer are disclosed that are receptive to paints and ink coatings. The polymer composition contains a polyoxymethylene polymer having a relatively high functional group content in combination with a coupling agent, a texturizing agent, and optionally a thermoplastic elastomer. The polymer composition can be molded into various articles at a mold temperature less than about 125° C., such as from about 60° C. to about 120° C. and then painted or printed with an ink composition. The polymer composition has been found to dramatically improve adhesion between the molded article and the ink or paint coating.
