Claims13
A process for the preparation of negatively charged toner compositions with a negative triboelectric charge of from about a negative 10 to about a negative 30 consisting essentially of admixing toner resin particles, green pigment particles comprised of HELIOGEN GREEN.TM., and a positive charge enhancing additive selected from the group consisting of cetyl pyridinium chloride and distearyl dimethyl ammonium methyl sulphate incorporated. pigment particles, and a positive charge enhancing additive incorporated into said toner composition that enables passivation of said green pigment particles, and subsequently adding thereto surface additives and wherein said passivated green pigments enable the minimization or avoidance of adverse effects on the toner triboelectric charging characteristics and wherein said toner compositions have rapid admix characteristics with an admix time of from about 15 to about 60 seconds.
A color imaging process which comprises the development in sequence of latent images formed on an imaging member with a toner comprised of resin particles, HELIOGEN GREEN.TM. pigment particles, a charge enhancing additive, and surface additive particles.
