    摘要: A coating composition containing about 45-80% by weight of a binder and 20-55% by weight of an organic liquid; wherein the binder contains (A) about 40-90% by weight, based on the weight of the binder, of an acrylic polymer containing polymerized hydroxyl containing monomers of the following group of hydroxy alkyl acrylate or methacrylates having 1-4 carbon atoms in the alkyl group, and polymerized alkyl acrylates and methacrylates having 1-18 carbon atoms in the alkyl groups, or styrene or any mixtures of the above and 0.1-5.0% by weight, based on the weight of the acrylic polymer, of polymerized fluoroalkyl containing monomer represented by the formula ##STR1## where R is hydrogen or an alkyl group having 1-2 carbon atoms, n is an integer of 1-11 and R.sub.f is a fluoroalkyl containing group having at least 4 carbon atoms and (B) about 10-60% by weight, based on the weight of the binder, of a fluorinated organic polyisocyanate crosslinking agent.
