PROBLEM TO BE SOLVED: To provide opacifying particles that include certain pigments substantially encapsulated with a polymer and a method for forming them. SOLUTION: The opacifying particles including a pigment particle having an average particle diameter of from 0.005 to 5μm and an index of refraction of at least 1.8; a first polymer attached to the surface of the pigment particle via a silane residue, and a second polymer which substantially encapsulates the pigment particle having the attached first polymer is provided. A method for forming the opacifying particle as is a coating composition and a plastic composition including the opacifying particle are provided. COPYRIGHT: (C)2006,JPO&NCIPI |
