    摘要: A waterborne acetoacetate-functionalized alkyd coating composition is disclosed which includes an acetoacetate-functionalized alkyd resin, at least one drier, and water. The acetoacetate-functionalized alkyd resin is the reaction product of (i) an alkyd resin, and (ii) an alkyl acetoacetate. Also disclosed is a method of preparing a waterborne acetoacetate-functionalized alkyd coating composition which includes the step of contacting an acetoacetate-functionalized alkyd resin with at least one drier in the presence of water.

    摘要: An aqueous-dispersion comprising a polyester (A) having repeat units from at least one dicarboxylic acid, at least one difunctional sulfomonomer containing at least one metal sulfonate group attached to an aromatic nucleus wherein said functional groups are carboxyl or hydroxyl, and at least one difunctional glycol; and a polymer (B) having repeat units from styrene or one or more derivatives of styrene; a hydroxyalkyl(meth)-acrylate; and a carboxyl group containing monomer selected from methacrylic acid, acrylic acid, itaconic acid and mixtures thereof. Polymer (B) is formed from monomers polymerized in the presence of an aqueous dispersion of polyester (A). The aqueous dispersion may be used in various coatings and inks having excellent water resistance, alkaline resistance, and redispersibility.
