Abstract
Negative-working, infrared radiation-sensitive lithographic printing plate precursors have an imageable layer on a substrate. The imageable layer includes a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to infrared radiation, a polymeric binder, one or more infrared radiation absorbing compounds, and an inorganic phosphoric acid or inorganic phosphoric acid precursor. The lithographic printing plate precursors can be designed for either off-press or on-press development after IR imaging.
