PREPARING IMAGING MEMBER WITH MICROGEL PROTECTIVE LAYER

Title:

PREPARING IMAGING MEMBER WITH MICROGEL PROTECTIVE LAYER

Document Type and Number:

WIPO Patent Application WO/2004/104705

Kind Code:

A1

Abstract:

Various imaging members including lithographic imaging members can be prepared by applying to a support, an aqueous formulation comprising one or more imaging components to form an imaging layer. Over the imaging layer is directly applied a non-aqueous inverse emulsion comprising highly hydrophilic, water-swellable microgel particles dispersed in a water-immiscible organic solvent to form a protective layer. This protective layer provides physical durability but it is still readily removed during or after imaging with water or fountain solutions.
