<p>A coating composition that forms a finish that is soil resistant and easily cleaned having a binder of (A) an acrylic polymer of polymerized hydroxyl containing monomers of hydroxy alkyl (meth)acrylates having 1-4 carbon atoms in the alkyl groups and polymerized monomers from the group of alkyl (meth)acrylates having 1-18 carbon atoms in the alkyl groups, styrene or any mixtures of the above and the acrylic polymer has a weight average molecular weight of about 2,000-20,000 determined by gel permeation chromatography; (B) an acrylic polymeric additive of polymerized hydroxyl containing monomers of hydroxy alkyl (meth)acrylates having 1-4 carbon atoms in the alkyl groups, polymerized monomers from the group of alkyl (meth)acrylates having 1-18 carbon atoms in the alkyl groups, styrene or any mixtures of the above and polymerized fluoro alkyl containing monomer represented by formula (I) where R is selected from the group of hydrogen or an alkyl group having 1-2 carbon atoms, X is a divalent radical and Rf is a fluoro alkyl containing group having 4-20 carbon atoms and the additive has a weight average molecular weight of about 1,000-15,000 determined by gel permeation chromatography; and (C) an organic cross-linking agent; and where a cured layer of the coating of the composition has a combination of advancing water contact angle of at least 100° and a hexadecane advancing contact angle of at least 40°. Articles coated with the composition also are part of this invention.</p> |
