The external additive does not react or has no interaction with an organic photoreceptor and therefore change in quality does not occur or the photoreceptor is not scraped. Furthermore, it has a good flowability and therefore adhesion of a toner to the photoreceptor does not occur.

  • Patent number: 6786965
    Abstract: An aqueous organic pigment dispersion used to integrally color concrete and other building materials which includes: alkali metal silica particles as a binder; organic pigment; water; and dispersing agent in an amount effective to disperse the organic pigment and the binder in the water. A method for preparing the aqueous organic pigment dispersion includes (i) mixing, at 3,000 to 10,000 rpm, alkali metal silica particles; organic pigment; and dispersing agent, thereby forming a dispersion premix; (ii) milling the dispersion precursor in a mixer filled with glass beads for a period of time sufficient to reduce the particle size of the organic pigment to about 100 to about 300 nanometers, thereby forming a non-standardized dispersion; and (iii) standardizing the dispersion against a color standard by adding water.
