  • Patent number: 9452631
    Abstract: A light-emitting medium including a light-emitting image having a pattern area formed on a substrate by using a first fluorescent ink containing a first fluorescent material, a background area formed on the substrate by using a second fluorescent ink containing a second fluorescent material, and a overcoat layer formed on the first fluorescent material of the pattern area and the second fluorescent material of the background area. The first fluorescent material is made of a fluorescent material which emits light of blue color when UV-A is irradiated, and emits light of red color when UV-C is irradiated. The second fluorescent material is made of a fluorescent material which emits light of blue color or light of a color that is viewed as the same color as the blue color when the UV-A is irradiated, and emits light of green color when the UV-C is irradiated.

  • Patent number: 8523238
    Abstract: There is provided a light-emitting medium by which whether a valuable paper or the like is forged or not can be judged easily and promptly. A light-emitting medium constituting a valuable paper includes a light-emitting image. The light-emitting image is composed of a pattern area formed on a substrate by using a first fluorescent ink containing a first fluorescent material, and a background area formed on the substrate by using a second fluorescent ink containing a second fluorescent material. When UV-A is irradiated, the first fluorescent ink and the second fluorescent ink emit light of colors that are viewed as different colors from each other. In addition, when UV-C is irradiated, the first fluorescent ink and the second fluorescent ink emit light of colors that are viewed as different colors from each other, the colors being different from the colors that are viewed when the UV-A is irradiated.

  • Patent number: 7011931
    Abstract: A process for forming an electrode pattern for a plasma display panel, the process including coating a photosensitive conductive paste on a film to form a pattern forming layer, laminating the film onto a substrate with the pattern forming layer facing the substrate, exposing the pattern forming layer from above the film through a mask, separating and removing the film and developing the pattern forming layer to remove unexposed areas, and firing the substrate to adhere the exposed areas of the pattern forming layer to the substrate, thus forming an electrode pattern thereon.
