A method for making the particles is provided wherein a latex copolymer functions as a stabilizer controlling particle size of the core composition of the toner particles. The latex copolymer becomes the shell composition thereof. The particles are particularly useful in a process for transferring a toned image comprised of such particles from a photoconductor to a receiver.

    摘要: A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of a pigment by depositing thereon a coating of a low melting point wax. The method involves preparing a mixture of a wax solution and a pigment dispersion which is heated to a temperature sufficient to assure dissolution of wax and permitting the mixture to cool slowly to room temperature at which point a coating of wax is deposited upon the surface of the pigment. The wax coated pigment particles are then used as a component of the organic phase in a limited coalescence process.

    摘要: A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of a pigment by depositing thereon a coating of a low melting point hydrophobic semi-crystalline polyester wax. The method involves preparing a wax solution by dissolving at ambient temperature a low melting point hydrophobic semi-crystalline polyester wax in a first solvent capable of dissolving the wax at ambient temperature; forming a pigment dispersion by mixing at ambient temperature a pigment, a first polymer material and a second solvent in which the hydrophobic wax is insoluble at ambient temperature; admixing the wax solution with the pigment dispersion so resulting in precipitation of the wax upon the surface of the pigment; mixing the wax coated pigment dispersion thus formed with a solvent in which the hydrophobic wax is insoluble at ambient temperature and, optionally, a second polymer material and, optionally, a charge-control agent to form an organic phase; dispersing the organic phase in an aqueous phase comprising a particulate stabilizer and, optionally, a promoter; homogenizing the resultant mixture, and evaporating the solvent and washing and drying the resultant product.
