Abstract
On-press developable, negative-working lithographic printing plate precursors have a sulfuric acid anodized aluminum-containing substrate in which the oxide layer pores have been widened using an acidic or alkaline treatment. Over the widened pores, a hydrophilic coating is applied, which coating comprises a non-crosslinked hydrophilic polymer having carboxylic acid side chains. This particular substrate provides improved adhesion and printing durability for on-press development and printing.
