Abstract
A method for manufacturing a thin metal film with an embossed pattern, which enables the precise transfer of the embossed pattern and generates a strong interference color is provided. An embossing belt having an embossed pattern formed on one surface thereof is coated with a thermosetting transparent resin The transparent resin is dried and cured and is coated with PVA which is sintered to form a PVA layer whereby the transfer of the embossed pattern is completed. After that, the transparent resin with the PVA layer bonded to the surface opposite to the embossed pattern is peeled from the embossing belt and reeled in, and an aluminum layer is deposited on the surface of the belt on which the embossed pattern is formed. The aluminum layer is coated with another transparent resin and the PVA layer is removed through a dissolving step. Resulting resin layers are pulverized to create a hologram pigment.
