ABSTRACT:
A water-dispersible polymer and a coating composition containing the water-dispersible polymer are disclosed. The water-dispersible polymer is prepared from: (a) an epoxy compound having about two epoxy groups, such as an epoxy resin, (b) a linking compound having (i) conjugated carbon-carbon double bonds or a carbon-carbon triple bond and (ii) a moiety capable of reacting with an epoxy group, such as sorbic acid, and (c) acrylic monomers, at least a portion of which are capable of rendering the polymer water dispersible, such as acrylic acid, wherein the epoxy portion (a) of the polymer is covalently linked to the polymerized acrylic portion (c) by linking compound (b). The coating composition contains the water-dispersible polymer, a fugitive base to solubilize the polymer, a curing agent, and a carrier containing water.
