摘要：The present invention relates to a stable aqueous dispersion of multiphaseamphoteric polymer particles comprising a crosslinked polymer phase comprisingstructural units of a phosphorus acid monomer, a carboxylic acid monomer, amultiethylenically unsaturated monomer, and an ethylenically unsaturated nonionicmonomer; and a second polymer phase comprising a carboxylic acid monomer and anethylenically unsaturated nonionic monomer. The present invention also relates tocomposites of the particles and pigment particles such as TiO. The composition is usefulfor preparing dried coatings with improved hiding.
