Abstract
Highly versatile stable photoresist emulsions can be prepared using low levels of neutralization while minimizing the use of surfactants and associative thickeners. High solids, low viscosity waterborne photoresist emulsion compositions are prepared by mixing and comminuting a partially neutralized acid functional latex polymer resin with photopolymerizable monomers and photoinitiators under conditions sufficient to produce a stable emulsion.
