  • Publication number: 20040234891
    Abstract: Various imaging members including lithographic imaging members (such as printing plates) have an aqueous-based imaging layer applied to a support. Directly over the imaging layer is a protective layer that is applied as a non-aqueous inverse emulsion comprising highly hydrophilic, water-swellable microgel particles dispersed in a water-immiscible organic solvent. This protective layer provides physical durability but it is still readily removed during or after imaging with water or fountain solutions.

  • Patent number: 6821720
    Abstract: A method of producing a thermal-developable photosensitive material is provided, which prevents mixing of materials between layers to ensure that the coating surface is in a good condition. In this method, liquids for forming a photosensitive layer, an intermediate layer and a protective layer are simultaneously applied in a multilayer form on a substrate to produce a thermal-developable photosensitive material. A pH of the intermediate layer coating liquid is adjusted within a range from 5 to 10 and a viscosity of the intermediate layer coating liquid is adjusted within a range from 20 to 150 mPa·s. Moreover, a pH buffering salt is added to the intermediate layer coating liquid.

  • Patent number: 6818367
    Abstract: The invention relates to an imaging element comprising an imaging layer and a support, wherein the support comprises a base material having thereon at least two polyolefin layers, wherein the uppermost layer of the at least two polyolefin layers comprises a mixture of optical brighteners comprising a Compound A having the following formula: a Compound B having the following formula: and a Compound C having the following formula: wherein the layers below the uppermost layer of the at least two polyolefin layers comprise migratory optical brightener; and wherein the imaging layer is on the same side of the base material as the at least two polyolefin layers. The inventive support unexpectedly minimizes exudation of the brightener at the polyolefin surface and provides excellent absorption/emission characteristics, brightening power and heat to meet the critical requirements of the photographic field.
