1. A coating composition comprising:
A) 1 to 94.95% by weight of an aqueous solvent comprising water; B) 5 to 80% by weight of a polymer binder comprising polymerized units derived from one or more ethylenically unsaturated monomers, an acid-functional residue, and a polyvalent metal ion; and C) 0.05 to 10% by weight of a water soluble poly(ethylene oxide) resin having the general formula [—CH2CH2O—]n, wherein n is selected to provide a weight average molecular weight of 100,000 to 1,000,000 grams per mole of the water soluble poly(ethylene oxide), wherein a single coating of the coating composition provides a 60° gloss of 2.3 to 13.3 and a two-coat burnish resistance of 1.1 to 3.8, wherein the gloss is determined in accordance with ASTM D 1455 (2000) and wherein the burnish resistance is determined as a difference in 85° gloss before and after rubbing with a gauze sponge for 5 cycles. |
