  • Patent number: 4849784
    Abstract: A transfer device and method of its use for an electrostatic imaging system using liquid toner capable of generating images having very high resolution at fast speeds. The station includes three sections, an electrically biased tack down roller, a transfer corona station and a transfer medium separator. These sections are located to prevent the onset of turbulence in the liquid toner.

  • Patent number: 4810624
    Abstract: To protect photographic films from imaging by static discharges during manufacturing and customer use, copolymers of sulfonated monomers and primary amine monomers are coated on a film base and crosslinked with an aldehyde such as glutaraldehyde, or other colloid hardener giving a water-resistant, permanent, conductive (i.e., antistatic) layer.
    Type: Grant

    Date of Patent: March 7, 1989
    Assignee: E. I. DuPont de Nemours and Company
    Inventors: William M. Hardam, Frank L. Schadt, III, Arthur J. Taggi
  • Patent number: 4794066
    Abstract: Improved liquid electrostatic developer containing electrostatic toner particles is prepared by a process wherein an aqueous, e.g., water-wet pigment cake is flushed with a water insoluble vehicle, water is removed, and the developer is formed from the flushed pigment dispersion, thermoplastic resin, dispersant nonpolar liquid having a Kauri-butanol value of less than 30, in a vessel at elevated temperature under high shear, and the dispersion is cooled. The liquid electrostatic developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.

    Inventors: Lyla M. El-Sayed, Arthur J. Taggi
  • Patent number: 4670370
    Abstract: Process for preparation of toner particles for electrostatic imaging comprisingA. dispersing at an elevated temperature in a vessel a thermoplastic resin, a dispersant nonpolar liquid having a Kauri-butanol value of less than 30 and a colorant other than black, e.g., yellow, cyan, magenta, the temperature being maintained to plasticize and liquify the resin and below that at which the nonpolar liquid degrades and any component decomposes:B. cooling the dispersion, either(1) with or without stirring to form a gel or solid mass, the shredding and grinding the mass by means of particulate media in the presence of additional liquid;(2) with stirring to form a viscous mixture and grinding by means of particulate media in the presence of additional liquid; or(3) while grinding with particulate media thereby preventing formation of a gel or solid mass in the presence of additional liquid, andC. separating the dispersion of toner particles, average by area particle size less than 10 .mu.
