MATTE METAL TONE DECORATIVE SHEET AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2016/152252

A1

[Problem] The purpose of the present invention is to provide a matte metal tone decorative sheet with which a matte metal tone decoration can be easily implemented, and a manufacturing method therefor. [Solution] The present invention is characterized by heating a decorative sheet in which at least a metal thin film layer is partially laminated on a base material sheet having stretching properties, so as to evenly generate micro cracks in the metal thin film layer and obtain a matte metal tone. The base material sheet is made easily stretchable by the heating, but the metal thin film layer is not capable of following the stretching of the base material sheet and receives a tensile force from the base material sheet. Accordingly, the micro cracks can be evenly generated in the metal thin film layer. That is, since there is no need to partially form irregularities or a matte layer on the base material sheet, the number of processing steps can be decreased and the aligning accuracy at the boundary between a gloss portion and a matte portion can be improved.
