METHOD FOR PRODUCING HOLOGRAM TONE DECORATIVE SHEET, RIBBON FOR FORMING HOLOGRAM TONE PATTERN USED IN THE METHOD, AND METHOD FOR PRODUCING IN-MOLD DECORATIVE MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide: a method for producing a hologram tone decorative sheet which does not need printing of ink containing a hologram pigment and is effective to improve productivity by cutting down the process; a ribbon for forming a hologram tone pattern used in the method; and a method for producing an in-mold decorative molded product.;SOLUTION: In the ribbon for forming the hologram tone pattern, a film with the total thickness of 0.5-3 μm is formed on a first base sheet 10, and the film includes a laminated film of at least a heat-shrinkable front anchor layer 6 and a thin metal film layer 7. The ribbon is piled up with a decorative sheet 3 where a pattern layer 24 is formed on a second base sheet 30. By applying controlled heat from the back of the ribbon for forming the hologram tone pattern, while the thin metal film layer of the ribbon for forming the hologram tone pattern is changed to a hologram tone pattern layer, the hologram tone pattern layer is transferred from the ribbon for forming the hologram tone pattern, and formed on the surface of the second base sheet on which the pattern layer is formed.;COPYRIGHT: (C)2010,JPO&INPIT
