Definitions

  • the present invention relates to an inkjet printing method, a coloring composition, an inkjet ink, an ink cartridge, and a dye polymer.
  • a colorant used for coloring a fabric is either a dye or a pigment.
  • a screen printing method, a roller printing method, a transfer method, Inkjet systems have been used.
  • the inkjet method does not need to prepare a plate as compared with other methods, can quickly form an image with excellent gradation, and uses only a necessary amount of ink as a formed image. It can be said that this is an excellent image forming method having environmental advantages such as few.
  • Patent Document 1 describes ink jet printing in which a dye is dissolved in water to prepare an ink, and a fabric is dyed by an ink jet method. Each dye molecule interacts with the fiber so that the dye penetrates into the inside of the fiber and is integrated with the fiber. Therefore, the fabric dyed with the dye has a soft texture and is preferred as a garment. .
  • ink-jet printing using dyes needs to be pre-applied with a printing paste as a pretreatment agent in order to prevent bleeding (improve sharpness), and in addition, the dye is fixed after dyeing. Therefore, it is necessary to steam-heat the colored fabric, and then wash the excess dye and the printing paste as the pretreatment agent by a process such as water washing or soaping.
  • An ink-jet sublimation transfer printing method has been widely put into practical use as a dyeing method that has improved the above-described complicated steps in normal ink-jet printing, the problem of time and labor required for the apparatus, and the problem of wastewater (see, for example, Patent Document 2).
  • a pattern to be printed using an ink-jet printer is printed on transfer paper with ink containing resin particles containing a disperse dye, and then the transfer paper and a polyester fabric are superposed and heat-treated.
  • This is a method for transferring the sublimable dye from the resin particles to the polyester fabric.
  • the dyeing mechanism in this system is said to be a phenomenon of thermal diffusion or thermal sublimation of dye molecules, or a mixture of both.
  • it mainly corresponds to dyeing
  • the used transfer paper cannot be recycled and becomes industrial waste.
  • an ink-jet coloring method using a pigment has also been studied (for example, see Patent Document 3).
  • a pigment and a surfactant as a dispersing agent are mixed in water and then finely dispersed with an attritor or a mill machine together with glass beads, zirconia beads, titania beads, stainless steel balls, etc., are used as a colorant. It has been. Then, this colorant is diluted with a reducer containing an emulsion resin for fixing the pigment, a pigment ink is prepared, adhered to the fiber by an ink jet method, and the resin is fused by a heating roller to fix the pigment. .
  • the coloring method using pigments does not require the selection of a colorant depending on the fiber type, and does not require a complicated steam heating (steaming) process or water washing process.
  • the pigment can be fixed. However, the pigment adheres to (is on) the fiber in the form of particles in which the dye molecules are gathered, and maintains fastness such as washing fastness and friction fastness of the colored cloth (colored cloth).
  • a large amount of emulsion resin must be used as a fixing agent, the texture of the colored cloth becomes stiff, and the quality as clothing is inferior to the colored cloth dyed with a dye.
  • the emulsion resin is dried due to the volatilization of water, the pigment ink is thickened, and a phenomenon such as clogging of the ink jet printer is likely to occur, resulting in poor workability.
  • Patent Documents 4 and 5 describe specific anthraquinone dyes and describe their use in camera and ophthalmic lens materials.
  • Patent Document 6 describes an ink-jet ink containing a polymer having a specific structure in which a specific dye is linked to a polymer skeleton.
  • Patent Document 7 describes an ink-jet ink containing polyurethane having a colorant structure.

  • coloring with a dye is excellent in the quality (texture, fastness) of the colored cloth, but it is necessary to select a dye depending on the fiber type, and the process such as a pretreatment process is complicated. There are some problems, problems that require equipment, and inferior environmental load such as waste water and waste materials. On the other hand, coloring with pigments does not require the selection of dyes based on the fiber type, and the process is simple, but has problems in workability such as clogging of ink jet printers due to thickening of ink, and coloring cloth There is a problem that many of them are inferior in quality (texture). Further, Patent Documents 6 and 7 do not specifically disclose textile printing, and do not describe any of the above problems.
  • the problem of the present invention is that various kinds of fabrics can be dyed, a pretreatment process is unnecessary, there is little environmental load, there is no problem in workability, and the sharpness and robustness of the obtained image are improved.
  • An object of the present invention is to provide an ink-jet printing method that is excellent in color cloth quality (texture).
  • another problem of the present invention is that various types of fabrics can be dyed, a pretreatment process is unnecessary, there is little environmental load, there is no problem in workability, and excellent sharpness and fastness. It is an object to provide a dye polymer, a coloring composition and an inkjet ink capable of providing a colored cloth excellent in image and quality (texture), and an ink cartridge filled with the inkjet ink.
  • the inventors of the present invention have made extensive studies to solve the above problems, and by using a water dispersion of a dye polymer containing a structure derived from a dye having an anthraquinone skeleton, a method of directly printing on a fabric by an inkjet method, It has been found that various types of fabrics can be dyed, a pretreatment process is unnecessary, there is little environmental load, there is no problem in workability, and an excellent quality colored fabric can be obtained. Although details are unknown as a mechanism by which the above problem can be solved by the above method, the present inventors presume as follows.
  • the aqueous dispersion of the dye polymer uses the dye polymer as an aqueous dispersion instead of an aqueous solution, bleeding does not occur as in the case of the pigment particles, a pretreatment process is unnecessary, and no water washing process is required, so no waste water is generated. In addition, since printing is performed directly on the fabric, waste such as transfer paper is not generated. Since the emulsion resin as the fixing agent is not used unlike the pigment ink, the viscosity of the ink is not increased and the workability is excellent. Furthermore, it is considered that the dye polymer is integrated with the fiber at the molecular level so as to cover the surface of the fiber regardless of the fiber type.
