Patent ID: 7709093

Claim:
A coating composition, comprising: (a) a film-forming component comprising a functional group-containing resinous binder that comprises (1) a polyurethane component wherein the polyurethane component is formed from the reaction of at least one polyisocyanate, at least one acid functional material or anhydride having at least one functional group reactive with isocyanate or hydroxyl groups of other components from which the polyurethane component is formed, and at least one active hydrogen containing material, wherein the residue of the active hydrogen containing material is a polyether group that is incorporated into the backbone of the polyurethane component; and (2) an active hydrogen containing water dispersible polymer component; and wherein said polyurethane component comprises anionic ionizable groups; and (b) a crosslinking agent having at least two functional groups that are reactive with the functional groups of the film-forming component (a), wherein, when the composition is applied and cured to form a cured coating, the cured coating is characterized as having a bicontinuous morphology.
