  • 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.
