PURPOSE:To accurately form an arbitrary metal pattern on the surfaces having various forms by forming a highly insulating resin layer ontg. black oil-soluble dyes on a substrate, whose surface is metal, removing the resin layer in an arbitrary form by YAC laser beams and depositing a metal on the removed part. CONSTITUTION:On a substrate (brass, etc.) whose surface, at least consists of a metal (Ni plating, Cr plating, etc.), a highly insulating resin layer (acrylic resin, polyester resin, etc.) at least contg. black oil-soluble dyes (nigrosine, etc.) is formed. After the resin layer is irradiated with YAC laser beams to remove it in an arbitrary form, the surface of the substrate at the remove part is treated by electric plating, etc., to deposit a metal. The residual resin layer is removed by a water solution of acid, alkali, etc. As a result, an arbitrary metal pattern is formed on the surface of the substrate. |
