Patent ID: 7388044

Claim:
A stable autodepositing aqueous dispersion comprising: (a) an epoxy pre-polymer; (b) at least one ethylenically unsaturated monomer polymerized through a heterophase polymerization process; (c) at least one hydrophobic water barrier enhancing agent; and (d) at least one latent curing agent, wherein the aqueous dispersion further comprises dispersion particles and components (a), (b), (c) and (d) are all present in one or more of the dispersion particles, and wherein the at least one hydrophobic water barrier enhancing agent is polymerizable and selected from group consisting of alkyl acrylates conforming to the general structure H 2 C═CHCO 2 —R1, alkyl methacrylate conforming to the general structure H 2 C═C(CH 3 )HCO 2 —R2, and mixtures thereof, wherein R1 is an alkyl group and R2 is an alkyl group.
