PURPOSE: A method for imprinting a hologram on a molded article by using uneven holograms is provided to improve quality of a molded article by imprinting holograms on not only a flat surface but also a curved surface of the molded article. CONSTITUTION: A method for imprinting a hologram on a molded article by using uneven holograms is as follows. A film is composed of a base material(111), a hologram receiving layer(112), and a metal deposited layer(113). The film is embossed with holograms so that uneven holograms are imprinted. The film imprinted with the uneven holograms is closely attached to an injection mold by a vacuum generator after inserting in the injection mold. Synthetic resin is put into the injection mold and heated and cooled in order to imprint the uneven holograms formed in the film on the molded article. |
