An aqueous composite particle composition containing composite particles and polyvalent metal ion is provided. The composite particles contain pigment particle with adsorbed polymer particles. The polymer particles contain pendant acid functional groups and has a molecular weight in a select range. Also provided are methods of preparing the aqueous composite particle composition. The aqueous composite particle composition is useful for preparing coating with high gloss and improved solvent resistance.

Aqueous composite particle composition

A binder composition for aqueous coatings that exhibit high gloss and superior corrosion resistance when applied to metal substrates comprising an aqueous emulsion copolymer, the copolymer including as polymerized units, at least one ethylenically unsaturated monomer and an ethylenically unsaturated strong acid monomer, such as phosphorus containing monomers, particularly phosphoethylmethacrylate; or salts thereof. Also provided is a method for achieving high gloss and superior corrosion resistance of metal substrates by coating a substrate with an aqueous coating composition comprising the binders of the present invention and drying, or allowing to dry, the aqueous composition.

Binder compositions for direct-to-metal coatings

Aqueous dispersion of copolymers formed by the polymerization of a monomer mixture containing 0.05% to less than 4.5% by weight of certain terminally unsaturated oligomers are useful for improving the scrub resistance, corrosion resistance, opacifying capacity and/or efflorescence resistance of a coating.
