    Abstract: A water dispersed coating composition comprises a mixture of (1) a water-soluble neutralized adduct of 4-14% by weight of an a ,b -ethylenically unsaturated dicarboxylic acid and/or anhydride with 86-96% of a drying or semi-drying oil, and (2) a latex of a copolymer of 25-66 mol. per cent conjugated diolefin and 34-75% styrene or derivative thereof, or a water-soluble aminoplast, or a water-soluble epoxy resin. The adduct is sufficiently neutralized e.g. with ammonia, an amine, or a quaternary ammonium hydroxide to form a clear solution in water at a pH of 7.5 without the use of organic solvents. It is also capable of forming a water-insensitive film when baked at 350 DEG F. for 30 minutes. A small amount of an amino-alkyl-alkanediol, e.g. 2 - methyl - 2 - amino - 1,3 - propanediol; 2 - ethyl - 2 - amino - 1,3 - propanediol, or 2 - methyl-2-amino-1,4-butanediol may be added to the neutralized adduct. Suitable latices for ingredient (2) of the compositions contain copolymers of:-styrene and butadiene; styrene and isoprene; 4-chlorostyrene and butadiene; 4-chlorostyrene and isoprene; 2- or 3-chlorostyrene and butadiene; a methyl styrene and butadiene; styrene, butadiene and methyl or ethyl acrylate. In the example compositions were prepared containing one of three adducts prepared from linseed oil with differing amounts of maleic anhydride; butadiene - styrene latex; TiO2; lamp black; talc; barytes; strontium chromate; suspending agent (Ben-A-Gel); anti-foaming agent; manganese naphthenate; pine oil; wetting agent (Tamol 731); ammonia; and water. The compositions were coated on phosphatized metal and baked.
