| 摘要 |
An aqueous coating composition comprising at least one aqueous binder latex, wherein the aqueous binder latex is prepared by (1) an aqueous phase polymerization of at least one olefinically monounsaturated, free-radically polymerizable monomer with at least one olefinically monounsaturated, free-radically polymerizable monomer with at least one acid group in organic solvent or in aqueous emulsion to form an acid functional (meth)acrylic resin, and neutralizing the acid groups of the formed polymer and (2) polymerizing in aqueous emulsion at least one olefinically unsaturated, polymerizable monomer with the resulting reaction product from (1) to form the aqueous binder latex, wherein the ratio by weight of the monomers of (1) to the monomers of (2) is in the range of from 10:90 to 90:10.
