Document Type and Number:
WIPO Patent Application WO/2023/044613
Kind Code:
A1
Abstract:
An aqueous coating composition contains: (A) an emulsion polymer comprising, based on the weight of the emulsion polymer, from 0.48 wt% to 1.20 wt% of structural units of a phosphorous acid monomer, a salt thereof, or mixtures thereof, from 0.5 wt% to 3 wt% of structural units of diacetone (meth) acrylamide, from 10 wt% to 80 wt% of structural units of a vinyl aromatic monomer, structural units of a C1-C24-alkyl ester of (meth) acrylic acids, and optionally, structural units of an α, β-ethylenically unsaturated carboxylic acid; (B) a specific amount of a dicarboxylic acid of formula (I) HOOC-R-COOH, a salt thereof, or mixtures thereof; and (C) from 0.05 wt% to 5 wt% of a flash rust inhibitor relative to the aqueous coating composition weight.
