  • Patent number: 8815982
    Abstract: A colored system including a coated substrate and a color pigment that adheres to the coated substrate, and a method for producing the colored system are described. The disclosed method adheres effectively the color pigments to the coated substrates. The resulting colored system avoids their separation during coating applications. The colored metallic paints/inks can be prepared by mixing a color pigment solution with a coated substrate solution. The resulting colored system displays vivid color and strong metallic luster.

  • Patent number: 8702861
    Abstract: An ink composition includes a water resistant aluminum pigment and water. The water resistant aluminum pigment is formed of an aluminum pigment and a covering film that contains Si and is formed on the surface of the aluminum pigment. A 50% average particle diameter of a corresponding circle obtained by calculation from areas of X-Y plain surfaces of the aluminum pigment is in a range from 0.5 pm to 3 pm. The coverage ratio of the covering film on the surface of the aluminum pigment, calculated from presence ratios of C, O, Al, and Si detected by XPS measurement at an incident angle of 30°, is in a range from 30% to 90%.
