<p>A substantially water-free, water-washable, energy-curable composition includes an epoxy oligomer and/or urethane oligomer having at least two ethylenically unsaturated moieties, at least one alkoxylated polyol monomer having at least two ethylenically unsaturated moieties and capable of being copolymerized with the oligomer, and a surface active agent capable of being integrated into the molecular structure of the cured polymer and further capable of rendering the uncured composition dispersible in water. Optionally, the composition can contain a photoinitiator. The composition is self-dispersible in water and is especially suitable for use as a coating material for a printing screen.</p> |
