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.
