Abstract:
A lithographic processing solution has a pH of less than 12 and comprises at least 0.001 and up to and including 1 weight % of a water-soluble or water-dispersible, non-IR-sensitive compound that has a heterocyclic moiety with a quaternary nitrogen in the 1-position of the heterocyclic ring, and has one or more electron donating substituents attached to the heterocyclic ring, at least one of which electron donating substituents is attached in the 2-position. This processing solution can be used to develop both single-layer and multi-layer positive-working lithographic printing plate precursors that have been imaged using infrared radiation.
