Abstract:
A pigment mixture comprising (a) pigment particles, (b) colloidal spacer particles dispersed on surfaces of the pigment particles, and (c) carrier particles, wherein the pigment particles with colloidal spacer particles are dispersed on surfaces of the carrier particles. A pigment mixture of titanium dioxide pigment particles having colloidal silica spacer particles on surfaces of the titanium dioxide, the titanium dioxide and colloidal silica attached to surfaces of diatomaceous earth carrier particles, provides improved optical efficiency of the pigment and improved retention in a paper fiber matrix.
