Definitions

  • U.S. Patent 3,962,513 discloses the use of a dual-layer coating construction for the production of lithographic printing plates.
  • the first layer was a coating of carbon black and nitrocellulose binder coated on top of a clear substrate.
  • An overlying layer of crosslinkable, ink-receptive resin was coated over this propellant layer. Upon laser heating, the resin was transferred to an aluminum plate. The run length and the image sharpness of the resulting plate were improved with this construction.
  • a thermally addressed element comprising a transparent (or translucent) substrate free of gas-producing polymer (polymers with a thermally available nitrogen content of greater than about 5 weight percent (as defined later herein) and having a black metal coating on one surface thereof can be used in a thermally addressed imaging process to produce a sharp black-and-transparent image on the substrate.
  • the element is directly addressed and the image is immediately formed thereon.
  • Microstructured PET films prepared as described in Example 6 were vapor coated with either aluminum or copper at a coating thickness of 1000 ⁇ .
  • the samples were imaged as in Example 1 except that the samples were imaged from the substrate side, the power on the film plane was 1.2 W, and the beam sweep speed was 48 m/sec.
  • the width of the imaged line segments were 10 ⁇ m.
