  • Pigment-dispersed aqueous recording liquid and printed material
    Patent number: 7348368
    Abstract: A pigment-dispersed aqueous recording liquid containing at least a pigment and a resin, which comprises from 60 to 200 parts by weight of the resin to 100 parts by weight of the pigment, wherein at least one of the resin is a water-dispersible urethane type resin, a weight fraction of a polyurethane urea part of which is at most 2.0 wt % to the urethane resin, and the pigment dispersed in the recording liquid has a dispersion particle size D50 of from 40 to 100 nm.
    Type: Grant
    Filed: March 3, 2004
    Date of Patent: March 25, 2008
    Assignees: Mitsubishi Chemical Corporation, Seiko Epson Corporation, Mikuni Shikiso Kabushiki Kaisha
    Inventors: Munetaka Kakiuchi, Shuichi Kataoka, Takashi Oyanagi, Kimihiko Ohya, Seiji Kamamasu
  • Coating formulation for printing plate precursor, printing plate precursor, printing press, fabrication process of printing plate, and regeneration process of printing Plate
    Publication number: 20060144271
    Abstract: Disclosed are a printing plate precursor, a fabrication process of the printing plate precursor, a fabrication process of a printing plate, a regeneration process of the printing plate, a printing press, and a coating formulation for the printing plate precursor. According to the present invention, a printing plate can be fabricated directly from digital data, and sufficient image quality can be obtained without a developing step, i.e., a developer. To permit repeated use of the precursor, the precursor has a surface, which contains a photocatalyst and is capable of showing hydrophilicity when exposed to activating light having energy higher than band gap energy of the photocatalyst.
