Abstract
A floor polish vehicle composition includes a polymer component having, among other monomers, carboxyl functional groups and at least one sulfur-containing acidic group, such as a sulfate or sulfonate group. An aqueous component of the floor polish vehicle component includes a multivalent transition metal ion, such as zinc, preferably present as a complex. Typically, the floor polish vehicle composition is an emulsion, wherein the copolymer component is a discontinuous phase and an the aqueous component is a continuous phase. The floor polish vehicle composition can include a polymer component that is a copolymer having carboxyl functional groups and anionic acid functional groups, wherein the anionic acid functional groups have a pK.sub.a of less than about 3.0. An example of a suitable anionic acid functional group is a sulfur-containing acid functional group, such as a sulfate or sulfonate acid group.
