发明名称 POLYBUTYLENE TEREPHTHALATE RESIN MOLDED ARTICLE HAVING PICTORIAL PATTERN FORMED THEREON AND PROCESS FOR PREPARING THEREOF
摘要 <p>A surface-patterned, injection-molded article of polybutylene terephthalate (PBT) is produced by placing a film composed mainly of a polyester 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 PBT resin to be injected thereinto. The polyester resin film has a melting point between 10.degree.C to 60.degree.C less than the melting point of the injected PBT. Molten resin composed mainly of polybutylene terephthalate is then injected into the mold cavity to cause the pattern-printed film to at least partially plasticize and thereby integrally meld (bond) onto a corresponding surface of the resulting molded PBT article.</p>
