  • Patent number: 7517555
    Abstract: A copper plating solution according to the present invention is characterized by that it comprising 0.03 mol/L to 0.5 mol/L of copper sulfate, 0.05 mol/L to 0.7 mol/L of ethylenediaminetetraacetic acid and 0.02 mol/L to 0.3 mol/L of sulfite, and has a pH adjusted to 5.0 to 8.5. A method for copper plating according to the present invention is characterized by that it comprises using the copper plating solution above. The copper plating solution and the method for copper plating according to the present invention stably provide a uniform copper plating film excellent in adhesion on the surface of an article to be plated, such as rare earth metal-based permanent magnet.

  • Patent number: 6987081
    Abstract: A colored metal sheet useful as a decorative member, a multi-colored signboard, etc. is provided by transfer-printing a topcoat or clear paint layer 4 formed on a substrate metal sheet 1 with a sublimation dye. A basecoat paint layer 2 and a primer paint layer 3 may be formed between the substrate metal sheet 1 and the paint layer 4. A sublimation dye penetrates into the paint layer 4 to form colored parts 5 extending along thickness direction of the paint layer 4. Glass flakes 6 (of 8 ?m or less in thickness and 10-70 ?m in length) and calcium silicate (of 1-8 ?m in primary particle size) may be dispersed in the paint layer 4, to improve slippage-proof property and wear-resistance. Powdery silica (of 0.5-8 ?m in particle size) may be dispersed in the paint layer 4, to improve anti-scratching property and wear-resistance.
