Abstract
A waterborne photoimageable composition or photoresist comprises a latex binder polymer having acid acid functionality to render it developable in alkaline aqueous solution, at least about 50 mole percent of the acid functionality being sulfonic acid moieties, a photopolymerizeable monomer fraction, and a photoinitiator chemical system.
