摘要：
An opacifying pigment encapsulated in polymer including a pigment particle having an average particle diameter of from 0.005 to 5 microns and an index of refraction of at least 1.8; an aminophosphorus acid-functional first polymer having been used to disperse the pigment particle in an aqueous medium; and a second polymer that at least partially encapsulates the dispersed pigment particle is provided. A process for forming the opacifying pigment encapsulated in polymer and compositions including the particles are also provided.
