摘要： A method for preparing a coating solution containing a cocrystallized titanyl phthalocyanine-titanyl fluorophthalocyanine, the method comprising: dry milling a charge-generation pigment or mixtures of charge-generation pigments; increasing the amorphousness of the pigment mixture as determined by X-ray crystallography using X-radiation characteristic of Cu Kα at a wavelength of 1.541 Å of the Bragg angle 2θ to provide an amorphous pigment mixture; contacting the amorphous pigment mixture with a first organic solvent having a gammac hydrogen bonding parameter of less than 9, with or without the presence of a dispersant material, to produce a crystalline pigment of the charge-generation pigment prior to contacting the pigment with a second organic solvent having a gammac hydrogen bonding parameter greater than 9; mixing at least one of a second organic solvent, a dispersant and a binder with the crystalline pigment/first solvent mixture without isolating the crystalline pigment to produce a mixture; and, adjusting the concentrations of the first organic solvent, crystalline pigment, binder, dispersants and second organic solvent as required to produce the coating solution of a selected composition.

摘要： A fine solid particle aqueous dispersion comprises dispersed particles of a substantially water insoluble nonpolymeric organic compound useful in imaging and a polymeric dispersant having an HLB number of at least 8. The dispersion can be prepared by(a) forming a coarse aqueous slurry of solid particles of said compound and a polymeric dispersant having an HLB number of at least 8; and(b) milling said slurry for a period of time sufficient to provide particles of the desired particle size of less than 0.5 micron.
