Definitions

  • the present invention relates to a water-soluble azo compound or a salt thereof, an ink composition containing the same, and a colored body colored with these.
  • ink ejection methods have been developed as recording methods using an ink jet printer, which is one of the representative methods. These all generate ink droplets and attach them to various recording materials (paper, film, fabric, etc.) for recording. In this method, since the recording head and the recording material are not in direct contact with each other, no noise is generated and the method is quiet. In addition, since it has the characteristics that it is easy to downsize, speed up, and colorize, it has been rapidly spreading in recent years and is expected to grow greatly in the future. Conventionally, inks such as fountain pens and felt pens, and inks for ink-jet recording have been used in which water-soluble pigments (dyes) are dissolved in an aqueous medium.
  • inks such as fountain pens and felt pens, and inks for ink-jet recording have been used in which water-soluble pigments (dyes) are dissolved in an aqueous medium.
  • a water-soluble organic solvent is added to these water-based inks in order to prevent clogging of ink at a pen tip or an ink discharge nozzle.
  • These inks give a recorded image of sufficient density, do not cause clogging of the pen tip and nozzles, have good drying properties on the recording material, have little bleeding, and have excellent storage stability. Such performance is required.
  • Ink jet nozzle clogging occurs when the water in the ink evaporates in the vicinity of the nozzle before other solvents and additives, and the pigment solidifies and precipitates when the composition state is low in water and high in solvents and additives.
  • the very important required performances is that solids are not easily deposited even when the moisture content in the ink is low. For this reason, high solubility in solvents and additives is one of the properties required for pigments.
  • a method for eliminating nozzle clogging a method using a dye having a high printing density is known. By using a pigment having a high printing density, the pigment content in the ink can be reduced while maintaining the conventional printing density. This not only makes it difficult to precipitate the dye, but is also advantageous in terms of cost, and development of a dye having a high printing density is desired.
  • the color area that can be expressed in a single color or mixed color becomes narrow, and the range of the color area that is desired to be expressed may be insufficient. For this reason, development of highly saturated pigments and inks containing them is desired.
  • the ink performance is required to be stable for long-term storage, high in recorded image density, and excellent in fastness such as water resistance, moisture resistance, light resistance and gas resistance. It is done.
  • the gas resistance means that a gas having an oxidizing action (also referred to as an oxidizing gas) existing in the air reacts with a dye (dye) of a recorded image on the recording material or in the recording material to record.
  • ozone gas is considered to be a main causative substance that promotes the discoloration and fading phenomenon of ink jet recorded images. Since this discoloration phenomenon is characteristic of ink jet recorded images, improvement of ozone gas resistance is an important technical problem in this field.
  • inkjet printers have the advantage that the type of recording paper is not limited, and the price of the printer itself is low, and the spread is particularly widespread in small to medium-sized office environments such as small offices and home offices (SOHO).
  • SOHO small offices and home offices
  • pigment ink does not dissolve in water-based ink, it does not enter a solution state, but is a dispersed ink. Therefore, when this is used for ink jet recording, there are problems with the stability of the ink itself and the nozzles of the recording head. Problems such as clogging occur.
  • pigment ink when pigment ink is used, there is often a problem in abrasion resistance. In the case of a dye ink, such a problem is considered to be relatively difficult to occur.
  • the moisture resistance is extremely inferior to that of a pigment ink, and an improvement to the problem is strongly desired.
  • dye ink tends to cause a problem that a dye attached to the surface of plain paper by ink jet recording penetrates more quickly toward the back side of the paper, resulting in a decrease in color density.
  • the ink receiving layer As one method for obtaining a photographic image-recorded inkjet image, there is a method of providing an ink receiving layer on the surface of a recording material.
  • the ink receiving layer provided for such a purpose often contains a porous white inorganic substance in order to speed up drying of the ink and to reduce bleeding of the pigment with high image quality.
  • the color fading due to the ozone gas is noticeable.
  • the above-mentioned color change of recorded images due to oxidizing gas is regarded as a problem. .
