摘要：
An opacifying pigment that includes 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 such as, for example TiO2, at least partially encapsulated in polymer is provided. Also provided are processes for forming the encapsulated pigment particle and compositions including the encapsulated pigment particle.
