1. A coating composition comprising:
(1) a first polymeric component which comprises a first polymeric dispersion, wherein first polymers contained in the first polymeric dispersion have a surface free energy of equal to or greater than 28 mJ/m2 and a volume average particle size diameter of from 0.1 to 10 microns;
(2) a second polymeric component which comprises one or more second polymeric emulsions wherein second polymers contained in the second polymeric emulsions have a surface free energy equal to or less than 26 mJ/m2 and a volume average particle size diameter from 0.005 to 1,000 microns;
(3) one or more rheology modifiers such that the coating composition has a viscosity of from 100 to 2000 cPs; and
(4) optionally, base to stabilize the first and second polymeric components;
wherein the first polymeric component is present in an amount such that the solids in the first polymeric component are from 50 to 99.9 wt % of a total solids content of the coating composition;
wherein the second polymeric component is present in an amount such that the solids in the second polymeric component are from 0.1 to 50 wt % of a total solids content of the coating composition; and
wherein the coating composition comprises from 50 to 99.9 wt % of the first polymeric dispersion and from 0.1 to 50 wt % of the second polymeric emulsion.
