Abstract:
A composition suitable for forming latex or emulsion formulations comprising an aqueous dispersion composed of a blended mixture of:(a) a derivative of a non-drying oil having an ethylenically unsaturated carboxylic acid ester of the formula: ##STR10##(b) at least one copolymerizable monomer selected from the group consisting of vinyl acetate, vinyl chloride, vinyl ester of C.sub.5 -C.sub.12 saturated tertiary branched carboxylic acids, acrylonitrile, acrylamide, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, glycidyl acrylate, glycidyl methacrylate, acrylic acid, butyl acrylate, butyl methacrylate, methyl methacrylate, methyl acrylate, para-acetoxystyrene, and styrene;(c) a drier selected from the group consisting of aliphatic carboxylic acid salts of cobalt, manganese, lead, zirconium, calcium, and mixtures thereof; and(d) one or more of anionic, cationic, amphoteric, or nonionic surface-active agent;wherein (i) R is either methyl or a multifunctional moiety having the structure: ##STR11##where R.sub.12 and R.sub.13 are the same or different and are independently selected from the group consisting of a saturated or unsaturated fatty acid chain;(ii) R.sub.9 is either hydrogen or methyl;(iii) a, a', b, b', and c, are integers, where a and a' have a value of from 2 to 4, b and b' have a value of 0 to 2 with the proviso that the sum of b and b' is 1 or 2, and c has a value of 5 to 12; and(iv) the total weight percent of (a) and (b) in said aqueous dispersion is at least from about 5 and not more than about 60 weight percent, based on total weight of the composition, wherein (a) and (b) are present in the weight ratio ranging from about 1:7 to about 1:20.
