Title:
COLORED METAL WIRE
Document Type and Number:
WIPO Patent Application WO/2010/071184
Kind Code:
A1
Abstract:
Conventional colored metal wires involve such a problem that the production costs are high due to use of expensive materials such as synthetic resin coating materials (such as polyester coating materials) used for metal wires, particularly for colored coated plated iron wires (steel wires), and vinyl chloride resins and polyethylene resins used for resin-coated plated iron wires (steel wires), in addition to use of pigments and dyes.  The present invention provides a colored metal wire which can be colored only by a comparatively low-cost chemical conversion liquid, without using the above-mentioned expensive materials at all. The colored metal wire is characterized by comprising a plating layer on the surface of a metal wire and a color layer that is formed on top of the plating layer and colored by chemical conversion, said layers being formed by a step of forming the plating layer by plating the surface of the metal wire which serves as the base material, and a succeeding step of forming the color layer by chemical conversion.
