ABSTRACT:
A surface-patterned, injection-molded article of polybutylene terephthalate is produced by placing a film composed mainly of a polybutylene resin and back-printed with a desired graphic and/or indicia pattern in a mold cavity so that the printed surface of the film will be in contact with resin to be injected thereinto. Molten resin composed mainly of polybutylene terephthalate is then injected into the mold cavity to bond the pattern-printed film integrally onto a corresponding surface of the resulting molded PBT article.
