摘要:
The toner for color electrophotography employing simultaneously fixing of various color toners, includes at least a coloring agent and a binder resin, wherein inorganic fine particles are internally added to the toner to have viscoelastic properties approximated to a level of other toners with different colors to be simultaneously fixed together therewith. The method for heat and pressure fixing a transferred image formed by toners of two or more colors on a recording medium using a heat roller, includes the step of fixing the transferred image formed by the above toner for color electrophotography together with black toner.
摘要:
A combination of powder coatings usable in a powder coating method for forming a coating film having visually homogeneous hue by mixing two or more powder coatings of which each color is different. In the combination of powder coatings, each of differences in triboelectric charges of two or more powder coatings is 5.0 μC/g or less. The coating method usable herein includes the step of applying onto a substrate to be coated two or more powder coatings of which each color is different, in which the triboelectric charges are controlled in the above given ranges.
摘要:
A toner for electrophotography comprising a resin binder comprising a crystalline polyester and an amorphous resin, wherein said crystalline polyester is dispersed in the resin binder in an amount of from 1 to 40% by weight, and wherein 90% or more of a dispersed domain of said crystalline polyester has a diameter of from 0.1 to 2 μm. The toner for electrophotography can be suitably used for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing, and the like.

The crystalline polyester can be suitably used for a resin binder for toner for electrophotography and the like used for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing, and the like; a polyester resin composition comprising the crystalline polyester.
摘要:
While plural kind of powder paints of different hues are mixed with each other without melting for preparation of a powder paint of a desire hue, a fluidity improver possessing a charge control function is simultaneously mixed into the powder paints without melting. The mixed powder paint containing the fluidity improver is charged, and then electrostatic powder coating is performed by the charged powder paint.
摘要:
The combination of powder coatings usable in a coating method comprising mixing two or more powder coatings of which each color is different, wherein each of the powder coatings fuses with each other and is heat-cured, to thereby give a coating film having a homogeneous hue. A powder coating composition comprising two or more powder coatings of which each color is different, wherein each of the powder coatings fuses with each other and is heat-cured, to thereby give a coating film having a homogeneous hue. A coating method comprising the steps of (a) applying to a substrate two or more powder coatings, of which each color is different; (b) heating to fuse with each other each of the two or more powder coatings applied in step (a); and (c) curing the resulting fused product in step (b), to give a coating film having a homogeneous hue.
摘要:
An electrostatic latent image formed on a light-sensitive body is developed by making a thermosetting powder coating material adhere under electrostatic force to the light-sensitive body. The powder coating material on the light-sensitive body is transferred from the transfer part of an intermediate transfer body which is softer than the light-sensitive body and the object to be coated, onto an object to be coated. The powder coating material is thermally set in such a way that it is able to bake onto the object to be coated.

摘要:
The present invention provides a process for producing toner particles having small particle size and small particle size distribution which uniformly contain a polyolefin wax in high yield by a simple process. That is, according to the present invention, there is provided a process for producing a toner which comprises dissolving or dispersing a polymerizable composition comprising:(I) a vinyl monomer,(II) an acrylic resin-grafted polyolefin, and(III) a colorantin a dispersion solvent and then polymerizing it, wherein no resin deposition occurs when the acrylic resin-grafted polyolefin (II) is dissolved or dispersed in a mixed solution of one volume of the vinyl monomer (I) and two or more volumes of the dispersion solvent.
