Abstract
An improved method of preparing embossed metallic flakelets for a hologram pigment improves productivity through a simpler process. A metallic foil 12 is first pressed between a cooperative pair of dies 10 having mutually complementary embossed patterns to thereby transfer to the surfaces of the metallic foil 12 the embossed pattern of the dies 10. Finally, the pulverized metallic flakelets are mixed with predetermined other ingredients to make a hologram pigment.
Claims12
A method of producing embossed metallic flakelets, comprising:
- pressing a metallic foil on its opposite surfaces between a cooperating pair of dies, which have two mutually complementary embossed patterns, to form on the surfaces of the metallic foil undulation corresponding to the embossed pattern of the dies;
- and
- pulverizing the metallic foil into metallic flakelets.
