Title: Plastisols made with polyelectrolyte binders

Abstract: Thermally coalescible plastisols and organosols of the invention comprise dispersions of single-phase particles of random polymers or copolymers that comprise organic polyelectrolytes that contain at least 1% by weight of ionizable monomer or comonomer, dispersed in a medium that comprises a nonvolatile liquid that is compatible with the resin. Incorporation of a photopolymerizable, ethylenically unsaturated compound provides photosensitive plastisols and organosols useful for making relief and planographic printing plates, photoresists, and the like.
