Definitions
- the present invention relates to a non-aqueous inkjet ink suitable for use in an inkjet recording system.
- the ink jet recording system is a printing system that performs printing by ejecting liquid ink having high fluidity from a fine nozzle and attaching it to a recording medium such as paper.
- This system is a relatively inexpensive device and has a feature that it can print high-resolution and high-quality images at high speed and with low noise.
- the ink coloring material used in the ink jet recording system is excellent in light resistance, weather resistance and water resistance necessary for high-quality printing, and therefore, the ink using pigment as the coloring material tends to increase.
- color printing is usually performed by three color ink sets including three subtractive primary colors of yellow (Y), magenta (M), and cyan (C), or black ( Various hues are expressed using four color ink sets to which K) is added. Since pigments have different structures and surface treatments, or have different particle sizes, when two types of pigments are used in one ink (for example, Y ink), the dispersion state of the pigment changes and storage stability is achieved. Sexuality worsens and color changes. For this reason, one pigment is usually used for each of the Y, M, C, and K inks.
- Patent Document 1 describes that the color developability of water-based ink is improved by mixing and using pigment dispersions dispersed by different dispersing means.
- Patent Document 2 describes a water-based ink that can improve glossiness when printed on glossy paper by microencapsulating a pigment mixture composed of a plurality of types of organic pigments using a resin having a dispersion function. ing.
- non-aqueous inks have poorer colorant and solvent detachability than water-based inks, and the colorant easily penetrates into the paper together with the solvent, so that the colorant hardly remains on the paper surface. For this reason, the non-aqueous ink has a problem that the image density and the saturation are lowered even when the color is adjusted by combining two or more kinds of pigments. For example, if the conventional four-color ink set M ink and Y ink are toned in vermilion, only a color with strong blueness and low saturation can be produced. Furthermore, when a mixed color is used, there is a problem that the color reproduction range becomes narrow.
- the ratio of the pigment in the ink is increased, a printed matter having a high image density can be obtained, but in this case, the saturation is further lowered. In particular, this phenomenon is more remarkable in the case of non-aqueous ink that easily permeates paper, particularly plain paper, than water-based ink. Further, increasing the proportion of the pigment in the ink causes a decrease in pigment dispersion stability and storage stability. Increasing the proportion of the dispersant can improve the pigment dispersibility, but doing so may increase the viscosity and cause clogging of the nozzles of the inkjet apparatus.
- the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-aqueous inkjet ink that can be printed with high saturation and has good storage stability.
- the non-aqueous ink-jet ink of the present invention is a non-aqueous ink-jet ink containing at least two kinds of color pigments, a pigment dispersant and an organic solvent, wherein the pigment is a watching red pigment and a benzimidazolone pigment. Is.
- the watching red pigment is C.I. I. Pigment Red 48: 1 or C.I. I. It is preferably at least one of Pigment Red 48: 3.
- the benzimidazolone pigment is C.I. I. Pigment Yellow 180 is preferable.
- the non-aqueous inkjet ink of the present invention is a non-aqueous inkjet ink containing at least two types of color pigments, a pigment dispersant and an organic solvent, and the two types of color pigments are a watching red pigment and a benzimidazolone pigment.
- a high-saturation vermilion print can be obtained, and an ink with good storage stability can be obtained.
- the non-aqueous inkjet ink of the present invention is combined with at least one non-aqueous inkjet ink selected from cyan ink, magenta ink, yellow ink or black ink. Since the saturation of the ink is improved, the color gamut, which is the color expression range, can be widened when a mixed color is used.
- the non-aqueous ink-jet ink of the present invention is a non-aqueous ink-jet ink (hereinafter also simply referred to as ink) containing at least two kinds of color pigments, a pigment dispersant and an organic solvent, and the two kinds of color pigments are a watching red pigment and It is a benzimidazolone pigment.
- Watching red pigment is C.I. I. Pigment Red 48, more specifically C.I. I. Pigment Red 48: 1, C.I. I. Pigment Red 48: 2, C.I. I. Pigment Red 48: 3, C.I. I. Pigment Red 48: 4, C.I. I. Pigment Red 48: 5, and these watching red pigments can be used either alone or in combination. From the viewpoint of dispersibility and stability, C.I. I. Pigment Red 48: 1 or C.I. I. More preferably, it is at least one of Pigment Red 48: 3.
- Benzimidazolone pigments include P.I. Y. 180, P.I. Y. 175, P.I. Y. 154, P.I. Y. 151, P.I. Y. 120, P.I. Y. 181, P.I. Y. 194 and the like, and these benzimidazolone pigments can be used alone or in combination as appropriate. From the viewpoint of dispersibility and stability, P.I. Y. 180 is more preferred.
- Benzimidazolone pigments have a monoazo or disazo structure, and the close structure to the watching red pigment is considered to be one of the reasons for ensuring storage stability. Even if Pigment® Red® 122 (quinacridone), Pigment® Red 146, or Pigment® Red® 269 (naphthol), which are widely used as magenta pigments, are used in place of the watching red pigment, storage stability cannot be ensured and saturation cannot be obtained. Further, when Pigment Red 57: 1 (brilliant carmine 6B) is used instead of the watching red pigment, the storage stability can be secured, but the saturation cannot be obtained. Depending on the type of benzimidazolone pigment, the saturation and tinting strength may vary slightly, but the difference is much greater with the Watching Red pigment, and the Watching Red pigment is effective in terms of color and saturation. it is conceivable that.
- the mixing ratio (mass% ratio) of the watching red pigment and the benzimidazolone pigment is preferably 90:10 to 10:90, more preferably 90:10 to 20:80, and even more preferably 90:10 to 50: More preferably, it is 50. If the mass ratio of the benzimidazolone pigment is too large, the saturation will be too high, and it will be difficult to visually obtain a difference in saturation due to changing the mass ratio.
- the total amount of these pigments is preferably 1 to 30% by mass, more preferably 3 to 20% by mass, and even more preferably 5 to 15% by mass with respect to the total amount of ink.
- the ink of the present invention can finely adjust the saturation and lightness by including various known pigments other than the watching red pigment and the benzimidazolone pigment.
- various known pigments can be used, but carbon black is preferable because it can be finely adjusted with a small amount.
- Preferred examples of carbon black include furnace black, lamp black, acetylene black, and channel black.
- the content of the carbon black pigment with respect to the total amount of the pigment is preferably 1.0% by mass or less, and more preferably 0.6% by mass or less. If the amount is too large, the saturation is greatly reduced, which is not preferable.

These may be used alone or in combination of two or more. When using 2 or more types mixed, it is necessary for a liquid mixture to form a single continuous phase.
