Description

Coloring composition, inkjet recording ink, inkjet recording method, and inkjet printer cartridge

The present invention relates to a coloring composition, an ink for ink jet recording, an ink jet recording method, and an ink jet printer cartridge.

The ink jet recording method is a method of printing by causing ink droplets to fly and adhere to a recording medium such as paper as is well known. This printing method is capable of printing high-resolution, high-quality images at high speed and easily with an inexpensive apparatus. In particular, in color printing, technical development has recently been carried out as an image forming method that can replace photographs. .

For example, Patent Documents 1 and 2 describe inks for inkjet recording containing xanthene compounds.

Japanese Unexamined Patent Publication No. 2013-133395 International Publication No. 2015/105108

However, further improvements in performance are required in the dye field.

The present invention is excellent in hue, saturation and coloring power (print density), can form an image having excellent light resistance, ozone resistance and moisture resistance, and is also excellent in ejection stability in an ink jet printer. It is an object of the present invention to provide a coloring composition, an ink jet recording ink using the coloring composition, an ink jet recording method using the ink jet recording ink, and an ink jet printer cartridge filled with the ink jet recording ink.

The present inventors diligently studied and found that the above problems can be solved by the following means. In the present invention, the concentration of the dye contained in the colored composition (ink) is reduced by combining the compound represented by the general formula (1) and the azo compound represented by the general formula (D). High coloring power (print density) and image fastness (light resistance, ozone resistance, and moisture resistance) can both be achieved while contributing to the improvement of ejection stability. In the present invention, by combining different dye nuclei having good hue and saturation and high coloring power, it was possible to satisfy coloring power and image fastness at a higher level than using each independently. Conceivable.
Although the detailed reason is not clear, when the xanthene dye represented by the general formula (1) and the azo dye represented by the general formula (D) are mixed (for example, in an ink for ink jet recording or an ink jet recording method). It was estimated that the required performance was achieved without causing a large drawback such as a decrease in light resistance and a decrease in ink ejection stability. ing.
