  • Apparatus for developing or peeling alkali-type photosensitive film
    Patent number: 4593986
    Abstract: A developing or peeling solution for developing or imagewisely peeling an alkali-type photosensitive film containing a suspension of released photosensitive film is regenerated by introducing one or more reagents and a gas for depositing the suspension in floating state and removing the floated deposit by a skimmer from the developing or peeling solution. The regenerated developing or peeling solution can be used again and again for the development or peeling.
    Type: Grant
    Filed: March 4, 1985
    Date of Patent: June 10, 1986
    Assignee: Hitachi Chemical Co. Ltd.
    Inventors: Yoshiaki Tomisawa, Seiji Kinoda, Eiji Fujita, Masanori Murata, Toshio Takeuchi, Ken Ogawa
  • Process for regenerating solution for developing or peeling alkali-type photosensitive film
