  • Lithographic fountain concentrate
    Patent number: 4530721
    Abstract: A lithographic concentrate capable of being mixed with water to provide a lithographic fountain solution comprising a low molecular weight polyacrylic acid, colloidal silica and, preferably, phosphate ion.
    Type: Grant
    Filed: September 20, 1983
    Date of Patent: July 23, 1985
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Gerard H. Kinderman, James F. Sanders
  • Photolithographic element containing a silver-receptive polyaldehyde-containing receiving layer
    Patent number: 4361635
    Abstract: A photolithographic sheet capable of forming a lithographic printing plate upon imaging via silver salt diffusion transfer comprising a support, a silver halide emulsion, and a receptor layer overlying the emulsion, the receptor layer comprising a high molecular weight hydrophilic polymer and catalytic nuclei for silver salt diffusion transfer development, the major proportion of the polymer being a dialdehyde polysaccharide.
    Type: Grant
    Filed: June 19, 1981
    Date of Patent: November 30, 1982
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Gerard H. Kinderman, James F. Sanders
  • Photographic speed transfer element with oxidized polyethylene stripping layer
    Patent number: 4226927
    Abstract: A presensitized photographic speed light sensitive sheet structure suitable for producing a dry transfer element, comprising a substrate having a release coating thereon, and overlying the release coating a photo-sensitive layer comprising a silver halide emulsion. After light exposure to an original and development, the remaining silver image portions have a greater adhesion for a receptor surface when applied thereto under pressure than the adhesion of the indicia to the substrate under like pressure.
    Type: Grant
