  • Patent number: 8337011
    Abstract: An inkjet recording sheet for forming an image using aqueous pigment ink that includes a substrate and an ink-receiving layer formed on the substrate. The ink-receiving layer is obtained by applying, on the substrate, a coating composition containing: a cationic acrylic silicone emulsion-based resin having a hydrolyzable silyl group as a crosslinking component; a cationic polyether-based urethane resin; and a carbodiimide group-containing resin, followed by curing the applied coating composition. In the coating composition, the content of the cationic acrylic silicone emulsion-based resin is 2 to 7% by mass, the content of the cationic polyether-based urethane resin is 88 to 94% by mass, and the content of the carbodiimide group-containing resin is 2 to 6% by mass in terms of solid matter.

  • Patent number: 5772840
    Abstract: A casing has an opening at an end thereof, a supply spool and a take-up spool are rotatably mounted in the casing. A pressure blade member is provided in a longitudinal direction of the casing. The pressure blade member has a pressure blade portion projected from the opening, and a shaft portion rotatably supported in the casing so as to be rotated about an axis thereof. A coil spring is mounted on the shaft portion so as to resiliently hold the pressure blade member. A tape is wound on the supply spool and on the take-up spool, and slidably attached on the pressure blade portion.

  • Patent number: 5693394
    Abstract: An adhesive fluorescent coloring layer is applied to a carrier, so that a pressure-activated fluorescent marking tape is formed. When pressure is applied to the back of the carrier, the adhesive fluorescent coloring agent layer is transferred to a substrate. A surface of the adhesive fluorescent coloring layer has a quality so that the adhesive fluorescent coloring layer can be removed from the substrate when applied with external force.
