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. Prior to mold placement, the back-printed surface is coated with an adhesive layer. Molten resin composed mainly of polybutylene terephthalate is then injected into the mold cavity to cause the adhesive to bond the pattern-printed film integrally onto a corresponding surface of the resulting molded PBT article.
