    摘要： A method for producing a magnetic recording medium while minimizing electrostatic charge buildup on the medium during production. The method comprises applying a liquid material over a surface of a moving web to form a continuous wet coating thereon and smoothing the wet coating with a flexible blade having two major surfaces. The flexible smoothing blade comprises a conductive layer and is positioned so that a portion of one major surface is in contact with the wet coating so that electrostatic charge on the coated web is continuously dissipated.

    摘要： A photolithographic plate, method for preparation thereof, and salt compound useful in the preparation, the method involving the treatment of a metallic silver image on a substrate with a homogeneously stable acidic aqueous salt solution comprising a ferricyanide anion for oxidizing the metallic silver and an organic cation capable of forming a water-insoluble, inherently oleophilic complex with oxidized silver, the cation being derived from a protonatable nitrogen-substituted hydrocarbon compound containing a formal imine group therein which is in resonant association with adjacent groups within the hydrocarbon compound.

    摘要： A thermal transfer system for transferring material in an imagewise manner by means of thermal transfer printing from a donor element to an image receiving element is used to prepare printing plates. In one construction, a donor element, which is prepared by coating a photoinitiator (and optionally a sensitizer) in a binder on a backing material, is used with an image receiving element, which is prepared by coating a photopolymer (and optionally a sensitizer) on a substrate having a microporous hydrophilic crosslinked silicated surface. In an alternative construction, a donor element, which is prepared by coating a sensitizer in a binder on a backing material, is used with an image receiving element, which is prepared by coating a photopolymer and photoinitiator on a substrate having a microporous hydrophilic crosslinked silicated surface. In yet another construction, a donor element, prepared by coating a thermal transfer layer containing a photopolymer, a photoinitiator and/or a sensitizer on a backing material, is used with an image receiving element having a microporous hydrophilic crosslinked silicated surface.
