  • Patent number: 9182697
    Abstract: Recording sheet for wet electrophotography, having excellent toner fixability and transferability when printing is carried out by using a wet electrophotographic system employing a wet toner. The recording sheet for wet electrophotography is a recording sheet to be used in a wet electrophotographic system wherein an image is transferred from a heated blanket roll to a recording sheet. The recording sheet comprises a substrate and a toner receiving layer provided thereon containing inorganic fine particles and having a pore volume with a pore radius of 100 nanometers or less measured by a nitrogen adsorption method of 0.3 mL/g or more.
    Type: Grant

  • Patent number: 5916734
    Abstract: Provided is a method for making a lithographic printing plate according to which the area of a silver thin film of non-image area of a lithographic printing plate material comprising a support, at least a hydrophilic layer on the support and a silver thin film on the hydrophilic layer is exposed by laser beams to be fused and/or decomposed by heat transformed from laser energy thereby to disclose the hydrophilic layer.
