WIPO Patent Application WO/2011/021673

Kind Code:

A1

Abstract:

Disclosed are a method for producing a decorative metallic article having a woodgrain metal (mokumegane) pattern, which is composed of a fired copper part formed by firing a copper-containing plastic composition and a fired silver part formed by firing a silver-containing plastic composition, and a decorative metallic article having a woodgrain metal pattern. Specifically disclosed is a method for producing a decorative metallic article having a woodgrain metal pattern, comprising: a plate-forming step for shaping each of a copper-containing plastic composition and a silver-containing plastic composition into a plate to give a copper plate and a silver plate; a laminating and bonding step for alternately laminating the copper plate and the silver plate on each other, then stretching the obtained multilayered plate in such a manner as to reduce the thickness thereof by 10% or more, and bonding the same; a decorative article-forming step for forming a copper-silver multilayered decorative article by using said multilayered plate; a copper-silver multilayered decorative article-drying step for drying said copper-silver multilayered decorative article; a woodgrain metal pattern-forming step for cutting or polishing the surface of the copper-silver multilayered decorative article thus dried to visualize a woodgrain metal pattern, and forming a notch; and a fired product-forming step for firing the decorative article thus notched to give a fired decorative article (69).
