PURPOSE:To ornament the surface of a metallic frame body made of titanium or high tensile aluminum alloy for spectacles so as to have good adhesiveness and excellent durability without corrosion by coating the surface thereof with an ABS resin and metallizing the same. CONSTITUTION:The surface of the metallic frame body 1 made of the titanium or high tensile aluminum alloy is roughened and the ABS resin film 2 is formed on the surface. The surface of the film 2 is subjected to metallizing such as chemical plating, vapor deposition, sputtering vapor deposition and thermal spraying of metal, etc. to form a metallic film 3 thereon, by which the surface is ornamented. |
