  • Electrostatic dissipative surface coating and high temperature label employing same
    Patent number: 10689548
    Abstract: An electrostatic dissipative coating composition comprises a phenoxy-epoxy resin system comprising from 40-80 parts by weight to 5-20 parts by weight of an epoxy resin. Carbon nanotubes are dispersed in the phenoxy-epoxy resin system. The coating composition includes at least one isocyanate crosslinking agent and at least one metal catalyst. In a further aspect, a label construction comprising the electrostatic dissipative coating composition is provided.

  • Laser-driven method and apparatus for lithographic imaging and printing plates for use therewith
    Patent number: 6095049
    Abstract: Apparatus and methods for imaging lithographic plates using laser devices that emit in the near-infrared region, and plates suitable for imaging with the apparatus and methods. Laser output either ablates one or more plate layers or physically transforms a surface layer, in either case resulting in an imagewise pattern of features on the plate. The image features exhibit an affinity for ink and/or a fluid to which ink will not adhere that differs from that of unexposed areas.

  • Lithographic printing members having secondary ablation layers for use with laser-discharge imaging apparatus
    Patent number: 5353705
    Abstract: Lithographic printing plates suitable for imaging by means of laser devices. Laser output ablates one or more plate layers, resulting in an imagewise pattern of features on the plate. The image features exhibit an affinity for ink or an ink-abhesive fluid that differs from that of unexposed areas. The plates also include a secondary ablation layer that ablates only partially, and in a controlled fashion, as a result of destruction of overlying layers.
