<p>PROCESSES This invention relates to a liquid radiation curable composition useful for coating and imaging which comprises (1) an acrylic or methacrylic terminated, urethane cor taining polyene, (2) a non-water soluble vinyl monomer diluent, preferably an acrylate or methacrylate monomer diluent, (3) a polythlol containing at least two thiol groups per molecule and (4) a photoinitiator. The composition on exposure to radiation, e. g., a U.V. light source, cures to a solid polythioether.</p> |
