  • Photosensitive relief printing plate and photosensitive intaglio printing plate
    Patent number: 5698373
    Abstract: The present invention relates to a photosensitive relief or intaglio printing plate comprising a base and a photocurable photosensitive layer formed on the base, the photocurable photosensitive layer containing a dye precursor which forms a dye upon irradiation of actinic light. A relief (convex) pattern or a concave pattern can be recognized by coloring, thereby facilitating the printing plate inspecting work. The developing solution used is not colored or contaminated.

  • Dry planographic printing plate and preparation thereof
    Patent number: 4342820
    Abstract: Provided is a presensitized planographic printing master plate requiring no dampening water for use in negative work which comprises a base substrate, a light releasing photosensitive layer overlying the base substrate and a silicone rubber layer overlying the photosensitive layer. When the printing master plate is exposed through a negative film and then treated with a developer, only the silicone rubber layer overlying the exposed photosensitive layer is removed, while the photosensitive layer remains as it is to form an image area. Dampening water is not required when printing is carried out.
