Abstract
A coating composition that forms a finish that is soil resistant and easily cleaned having a binder of PA1 (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, PA1 (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 the formula ##STR1## where R is selected from the group of hydrogen or an alkyl group having 1-2 carbon atoms, X is a divalent radical and R.sub.f 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 per…
