  • Patent number: 8425790
    Abstract: An ink composition for ink jet printing is provided which gives a cured object excellent in adhesion to metallic plates, resistance to etchants, and alkali removability and can be stably ejected with an ink jet apparatus. The ink jet composition for etching resists has a viscosity at 25° C. of 3-50 mPa s and includes monomers comprising: either a polymerizable phosphoric ester compound represented by general formula (I); a polyfunctional monomer having two or more ethylenic double-bond groups per molecule and having no phosphoric ester group, the content of the ethylenic double-bond groups being 4×10?3 to 8×10?3 mol/g; and a monofunctional monomer having one ethylenic double-bond group per molecule and having neither phosphoric ester group nor carboxy group. In the formula, X represents C1-3 alkylene, Y represents C2-3 alkylene, and R represents hydrogen or methyl.
    Type: Grant

  • 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.
