Waterborne photoresists having binders neutralized with amino acrylates

A photoimageable composition capable of being borne as an emulsion in an aqueous medium comprising

• A) between about 30 and about 80 wt % of a latex binder polymer having an acid number of between about 40 and about 250,
• B) between about 15 and about 50 wt % of alpha,beta-ethylenically unsaturated monomer(s), exclusive of amino acrylates,
• C) between about 0.1 and about 25 wt % of a photoinitiator or photoinitiator chemical system which generates free radicals,
• D) between about 0.1 and about 20 wt % of an aminoacrylate(s) so as to neutralize between about 1 and about 40 mole percent of the acid functionality of the latex binder polymer;
• and
• E) up to about 40 wt % of an additional neutralizing base and/or polyether polyurethane associate thickener in amounts in conjunction with said aminoacrylate(s) sufficient to stabilize the photoimageable composition as an aqueous emulsion,
• the weight percentages being based on total weight of components A-E.
