Abstract
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.
