Fuente: WIPO "tomato" A seed coating composition comprises an aqueous polymer dispersion, obtainable by radical aqueous emulsion polymerization of a mixture comprising a) ethylenically unsaturated monomers M, with M comprising at least one vinyl ester M1, and at least one (meth)acrylic acid ester M2, b) a carboxyl-groups-containing compound CGCC, c) at least one non-carboxylated saccharide and/or polysaccharide S, and d) at least one emulsifier selected from non-ionic and anionic surfactants, wherein the dispersion has a pH of up to 4. The aqueous polymer dispersion is useful as a binder in compositions, in particular in aqueous compositions for seed coating/dying, and seeds coated with such compositions show reduced dust formation without impaired flowability/sowability.
