Abstract
A toner composition comprised of resin particles, passivated pigment particles coated with a polymeric coating, and a passivated tribofiller component coated with a polymeric coating, and wherein the tribofiller component possesses the same, or substantially the same index of refraction as the resin particles in the visible region of the spectrum.
Claims21
A toner composition consisting essentially of resin particles passivated pigment particles encapsulated within a polymeric coating, and a passivated tribofiller component coated with a polymeric coating, and wherein the tribofiller component possesses the same, or substantially the same index of refraction as the resin particles in the visible region of the spectrum;
- and wherein said tribofiller is selected from the group consisting of orthoclase, albite, fused silica, a metal halide, magnesium oxide, soda lime, and glass.
A process for obtaining passivated toners by adding to toner resin particles colored passivated pigment particles encapsulated within a polymeric coating, and a passivated tribofiller component coated with a polymeric coating, and wherein the tribofiller component possesses the same, or substantially the same index of refraction as the resin particles in the visible portion of the spectrum;
- and wherein said tribofiller is selected from the group consisting of orthoclase, albite, fused silica, a metal halide, magnesium oxide, soda lime, and glass.
