Abstract: An ionographic process which comprises the generation of a latent image comprised of characters; developing the image with an encapsulated magnetic toner comprised of a core comprised of a polymer and magnetite and wherein the core is encapsulated within a polymeric shell; and subsequently providing the developed image with magnetic ink characters thereon to a reader/sorter device.

Abstract: An aqueous ink jet ink composition comprising pigment, water, and an (A.sub.n -B.sub.m) block copolymer wherein n represents the degree of polymerization of A and m represents the degree of polymerization of B, wherein A is styrene, and B is acrylic acid.

Abstract: A photoconditive imaging member comprised of a supporting substrate, a photogenerating layer comprised of a photogenerating pigment, or photogenerating pigments dispersed in a polystyrene/poly(methacrylic acid) (A.sub.n -B.sub.m) block copolymer wherein A is the anchoring block, B is the steric stabilizing block, and n and m represent the number of segments; and a charge transport layer.

Abstract: A photoconductive imaging member comprised of a supporting substrate, a photogenerating layer comprised of photogenerating pigments dispersed in a polystyrene/polyvinyl pyridine (A.sub.n -B.sub.m) block copolymer wherein n represents the degree of polymerization of A and m represents the degree of polymerization of B, and a charge transport layer.

Abstract: Disclosed is a toner composition comprised of pigment particles and monovinyl aromatic terpene copolymer resin particles, and more specifically styrene terpene copolymer resins.

Abstract: A process for the preparation of a more perfect crystalline form of the Type I polymorph of titanyl phthalocyanine which comprises dissolving a precursor titanyl phthalocyanine Type I in a solution of trihaloacetic acid and alkylene chloride; adding the resultant solution to a solvent thereby enabling precipitation of Type X titanyl phthalocyanine; separating the titanyl phthalocyanine Type X from the solution; followed by a first washing with an organic solvent and a second washing with water; slurrying the resulting Type X titanyl phthalocyanine in an organic solvent enabling conversion of said Type X to Type IV titanyl phthalocyanine; and thereafter, subjecting the Type IV titanyl phthalocyanine obtained to treatment with an organic solvent to enable said crystalline form of titanyl phthalocyanine Type I.
