ABSTRACT:
Embossed metallic flakelets have high damage resistance and can be produced readily. A method for production is also provided. The embossed metallic flakelets are produced by dip-coating an organic-inorganic composite layer 12 on upper and lower sides of a carrier layer made of a PVA film or the like by a sol-gel process, and pressing an original embossed pattern 14 having an embossed pattern against the organic-inorganic composite layer 12 under pressure to transfer the embossed pattern onto the organic-inorganic composite layer 12. A sample having the transferred embossed pattern is sintered, to form a metallic film 10 on the organic-inorganic composite layer 12 by deposition or the like. The organic-inorganic composite layer 12 is dip-coated on the metallic film 10 by a sol-gel process, they are sintered, the carrier layer is dissolved in water to separate the metallic film 10 which is held between the organic-inorganic composite layers 12 on the upper and lower sides of the carrier layer, and the separated metallic film 10 is pulverized into embossed metallic flakelets.
