    Abstract: The present invention relates to a process for preparing a multistage phosphorus acid functionalized latex polymer comprising the steps of: a) contacting a first acrylic monomer with a first phosphorus acid monomer under emulsion polymerization conditions to form a first stage polymer; then b) contacting the first stage polymer with a second acrylic monomer and a second phosphorus acid monomer under emulsion polymerization conditions to form the latex polymer. The latex polymer is useful as an absorbing polymer for pigment particles used, for example, in coatings formulations.
