    • A method of preparing a molded article by means of an in-mold decoration process, is described. The method includes, providing a laminate (4) of a plurality of separate realisable thermoplastic labels (14) superposed over a carrier film (26). A decoration (86) is applied in-line to the exposed second surface (68) of the labels (14), thereby forming a decorated laminate (5). The decorated laminate (5) is forwarded and indexed into a mold (20) such that the exposed first surface (77) of the carrier film (26) abuts at least a portion of the interior surface of the mold, and the decorated second surface (68) of the label (14) faces the interior space of the mold. Plastic material (e.g., thermoplatic material) is injected into the mold against the decorated surface of the label, thus forming a molded article. The carrier film (26) is then separated from the molded article. At least a portion of the surface of the molded article prepared in accordance with the present method is defined by the first surface (71) of at least one label. Molded articles that may be prepared according to the present method include identification cards, such as driver’s licenses and animal tags (e.g., cattle tags), and lenses, such as tinted ophthalmic lenses and sunshade lenses.
    • 描述了通过模内装饰工艺制备模塑制品的方法。 该方法包括提供叠置在载体膜(26)上的多个单独可实现的热塑性标签(14)的叠层(4)。 将装饰品(86)与标签(14)的暴露的第二表面(68)成直线地嵌合,由此形成装饰层压板(5)。 装饰的层压板(5)被引导并分度到模具(20)中,使得载体膜(26)的暴露的第一表面(77)邻接模具的内表面的至少一部分,并且装饰的第二表面 标签(14)的表面(68)面向模具的内部空间。 将塑料材料(例如,热塑性材料)注入模具中以抵靠标签的装饰表面,从而形成模塑制品。 然后将载体膜(26)与模制品分离。 根据本方法制备的模塑制品的表面的至少一部分由至少一个标签的第一表面(71)限定。 可以根据本方法制备的成型制品包括身份证,例如驾驶执照和动物标签(例如牛标签)和透镜,例如有色眼镜和遮阳镜。
