  • Photoreceptor and method involving residual voltages
    Patent number: 6406823
    Abstract: A photoreceptor including: a charge transport layer; a top charge generating layer sensitive to a first light wavelength; a bottom charge generating layer sensitive to a second light wavelength; and a substrate, wherein the charge transport layer is positioned anywhere above the substrate, wherein the photoreceptor exhibits in response to exposure by the first light wavelength a first photodischarge curve having a first residual voltage and the photoreceptor exhibits in response to exposure by the second light wavelength a second photodischarge curve having a second residual voltage.

  • Processes for pigment dispersion and articles therefrom
    Patent number: 5449582
    Abstract: A process for preparing ultrafine pigment dispersions comprising providing a solubilized mixture of pigment-Lewis acid complex and an aprotic organic solvent; precipitating the resulting solubilized complex into a protic solvent thereby forming a dispersion of ultrafine pigment particles; removing the aprotic and protic solvents to afford a wet cake containing finely divided pigment particles; optionally neutralizing and washing the wet cake particles; and redispersing the resulting ultrafine pigment particles in an aqueous solution, an organic solvent, or mixtures thereof, and a binder resin to form an ultrafine pigment and binder resin dispersion.
