Abstract
An imaging element is disclosed for making a lithographic printing plate comprising a lithographic support and an imaging layer comprising (i) a polymer having aryldiazosulfonate units and/or aryltriazenylsulfonate units and (ii) a compound capable of generating a radical and/or an acid upon exposure to UV light. The imaging element can be exposed by UV light and developed by water or an aqueous solution. Exposure and/or development can be performed on or off press.
