Abstract:
A polymer particle (10) useful for opacifying includes a polymer core (12) and a polymer sheath (16) surrounding the polymer core (12). The polymer core (12) is produced by polymerizing the polymer sheath (16) around the polymer core (12) in an emulsion. After at least a portion of the polymer core (12) is formed, a non-homopolymerizing monomer is added to the emulsion.
