Abstract
A low molecular weight, film-forming, polymerizable, ethylenically-unsaturated compound is water- and organic solvent-soluble (i.e., soluble in both water and organic solvents) but is readily converted on exposure to actinic radiation to a polymer that is solvent-insoluble (i.e., not soluble in water, organic solvents, or mixtures of water and organic solvents) and, in certain examples, is hydrophobic. The compound comprises the ethylenically-unsaturated derivative (i.e., an ester or an amide) of a sulfopolyol or sulfopolyamine having an ethylenic unsaturated functionality of 2 to 18 and an equivalent weight per ethylenic unsaturated functionality of less than 2500.
