Liquid Developing Composition Or Process (e.g., Using Toner Particles In Liquid Vehicle, Etc.) Patents (Class 430/45.2)
  • Patent number: 8628906
    Abstract: A method of printing, comprising: a) developing a latent image on a photosensitive surface with a visible toner, thereby producing a visible toner image; b) transferring the visible toner image to a surface of an intermediate transfer member; c) applying a layer of an adhesive material over at least a portion of the visible toner on the intermediate transfer member, but substantially not to any part of the surface of the intermediate transfer member which is not covered with the visible toner; and d) transferring the visible toner image and the layer of adhesive material from the intermediate transfer member to a printing medium, thereby causing the visible toner to adhere better to the printing medium than it would without the layer of adhesive material, wherein the adhesive material has a stronger adhesion to the printing medium than the visible toner.

  • Patent number: 8304154
    Abstract: The present invention provides a particle dispersion liquid including (meth)acrylic resin-containing hydrophobic particles, an acetylene glycol surfactant adsorbed to the hydrophobic particles, and water; the particle size, in a state of being swollen due to absorbing water until saturation, of the hydrophobic particles to which the acetylene glycol surfactant has been adsorbed being 1.1 to 2 times as large as the particle size of the hydrophobic particles in a dried state.

  • Patent number: 8039182
    Abstract: An object is to improve the adhesion strength between a circuit pattern and its substrate without increasing the resistance value of the circuit pattern in preparation of a circuit pattern holding substrate. A circuit pattern formation device 100 forms, after forming a precursor circuit-pattern 12 in the surface of a dielectric thin film body 4, a circuit pattern 14 onto a target substrate 23 from the dielectric thin film body. After forming an electrostatic latent image 2 in the upper surface of the dielectric thin film body, the electrostatic latent image is exposed using an exposure unit 3 to prepare a pattern. A development apparatus 7 supplies a conductive particle dispersion solution 6 to this pattern to form a precursor circuit-pattern. By energizing the circuit pattern holding substrate 8, in which an adhesive layer 22 is formed, the precursor circuit-pattern is temporarily transferred to the circuit pattern holding substrate.

  • Patent number: 7670732
    Abstract: An image forming method includes: by using a plurality of liquid developers having different colors, forming a plurality of single color images corresponding to the colors; transferring a non-fixed color image onto a recording medium; and fixing the non-fixed color image onto the recording medium. In the image forming method, each of the liquid developers includes an insulting liquid containing unsaturated fatty acid components and toner particles dispersed in the insulating liquid, and an oxidation polymerization accelerator that accelerates an oxidation polymerization reaction of the unsaturated fatty acid components during fixation is contained in the liquid developer forming the single color image that is positioned closest to the recording medium among the plurality of single color images forming the non-fixed color image.

  • Patent number: 7517622
    Abstract: A printing method comprising: forming a first image utilizing a liquid toner comprising carrier liquid and pigmented polymer particles having a first color; transferring the first image to an intermediate transfer member, forming at least one additional image utilizing a liquid toner comprising at least one carrier liquid and pigmented polymer particles having a second color, different from the first color, transferring the at least one additional image to the intermediate transfer member overlaid on the first image, to form a composite image on the intermediate transfer member; and further transferring the composite image to a further substrate, wherein said polymer particles in said first liquid toner and in at least one of said additional liquid toners have different compositions, aside from colorants, the differences in composition including at least one of different polymers or blends of polymers, different amounts or types of plasticizers, different amounts of solvated liquid and different compositions
