Surface-patterned polybutylene terephthalate resin molded articles and process for preparing such molded articles. |
摘要 |
<p>A surface-patterned, injection-molded article of polybutylene terephthalate 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 resin to be injected thereinto. The polyester resin film has a melting point between 10 DEG C and 60 DEG C less than the melting point of the injected polybutylene terephthalate. Molten resin composed mainly of polybutylene terephthalate is then injected into the mold cavity to cause the pattern-printed film at least partially to plasticize and thereby integrally bond onto a corresponding surface of the resulting molded polybutylene terephthalate article.</p> |
