Abstract

PURPOSE:To obtain a high metallic sheen equal to that of metallically glossy paper with a metal foil attached by a method wherein in a metallic powder- coated paper used for decorative paper, wrapping paper, and the like, a coating layer made of metallic powder containing fine scaly metallic powder specified in amount and dimension and a binder is provided. CONSTITUTION:Metallic powder-coated paper is formed by providing a coating layer made of a binder and metallic powder containing 10% or more fine scaly metallic powder having a major diameter of 3mum or less and a thickness of 100Angstrom or less. As the metallic powder, aluminum, zinc, silver and the like are appropriately used. The metallic powder is mixed with a binder, a solvent, and the like and applied to a paper substrate. As the binder, a polyester, polyacrylic ester, or other synthetic resin generally used as an ink binder is used. As the solvent, an ethyl acetate, a toluene. or the like generally used as an ink solvent is used.
