Abstract
A coating composition containing about 40-90% by weight of film forming binder and 10-60% by weight of an organic liquid carrier; PA1 wherein the binder contains about PA1 (a) 50-90% by weight, based on the weight of the binder, of a dispersed acrylic polymer having PA1 (i) a core of gelled polymerized ethylenically unsaturated monomers which is not soluble in the organic liquid carrier and having amine functional groups and having chemically grafted thereto PA1 (ii) substantially linear stabilizer polymeric components that are soluble in the organic liquid carrier and comprise polymerized ethylenically unsaturated monomers and have a weight average molecular weight of about 1,000-20,000 determined by GPC (gel permeation chromatography) using polystyrene as the standard; PA1 wherein the monomers of the core and the stabilizer polymeric components are individually selected from the following group of monomers of alkyl (meth)acrylates, wherein the alkyl groups have 1-12 carbon atoms, hydroxy alkyl (meth)acrylate, wherein the alkyl groups have 1-4 carbons atoms, styrene, alkyl styrene, vinyl toluene, acrylonitrile, glycidyl (meth)acrylate, isobornyl (meth)acrylate, alpha-beta ethyleni…
