Water reducible coating compositions

A water reducible composition which comprises on a 100 parts resin basis an aqueous or solution dispersion of a defoamer, volatile components and a resin, said resin consisting essentially on a 100 weight percent basis of polymerized monomeric units, said units being obtained from polymerized monomers in the following percentages:

• 64.5 to 84.5 percent of a hard hydrophobic enhancing units from monomers selected from the class consisting of styrene, .alpha.-methylstyrene, acrylonitrile, vinyl toluene, methyl methacrylate, vinyl chloride and vinylidene chloride;
• 15 to 35 percent of soft hydrophobic enhancing units from monomers selected from at least one acrylate selected from the class consisting of methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, lauryl acrylate, isodecyl methacrylate, butyl methacrylate, isobutyl methacrylate, at leas one vinyl ether selected from the class consisting of ethyl, butyl, octyl, decyl, and cetyl vinyl ether and/or at least one diene selected from 1,3-butadiene, isoprene and 2,3-dimethyl butadiene, provided that said diene monomers are not mixed together and copolymerized with vinyl chloride or vinylidene chloride;
• and 0.5 to 10 percent of a hydrophilic enhancing organic acid unit selected from the class consisting of acrylic, methacrylic, fumaric, itaconic and maleic acid, said volatile components comprising a volatile amine in sufficient amount to result in a pH of from 8 to 14 for the composition;
• a water insoluble organic solvent;
• and a water soluble solvent selected from the class consisting of ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, diethylene glycol monoethyl ether acetate, diethylene glycol diethyl ether, ethylene glycol monomethyl ether acetate, dipropylene glycol methyl ether, methyl ethyl ketone, propylene glycol ethyl ether, propylene glycol isopropyl ether, propylene glycol butyl ether, acetone, methyl propyl ketone and diacetone alcohol;
• the water insoluble organic solvent having a weight ratio of from 70:30 to 20:80 relative to the water soluble organic solvent, and 0 to 30 parts of a plasticizer having a melting point of about -40.degree. C. to about 25.degree. C., a boiling point of at least 95.degree. C., and a solubility parameter of about 8 to about 16, with the proviso that when water is present it is present in a volume ratio relative to the volatile components of at least 80:20.
