Embodiment 1

[0036] The magenta blue ink composition of the present embodiment comprises (following % all is weight %): 3% directness blue dye 199 (Bayer AG), 1.5% acid blue dye 90 (Orient Chemical), 3.0% tensio-active agent Tergitol 15-S-9 (Union Carbide), 12.0% ethylene glycol (Aldrich), 79.7% water, 0.1% buffer MES (Morpholinoethane sulfonic acid), 0.2% chelating agent EDTA, 0.5% fungicide Proxel GXL (ICI) .

[0037] The method of testing the water resistance is to measure the color properties of the inkjet-printed Omni-Ocean blue artwork, put it in deionized water for 30 minutes, take it out and let it dry naturally at room temperature, and measure the color properties again. The experimental results are listed in Table 1. The inkjet printer used in this water resistance test is a commercially available dedicated inkjet printer, and the paper used is plain paper, which is measured by a commercially available spectrometer.

Embodiment 2

[0039] The magenta ink composition of the present embodiment comprises: 3% directness blue dye 86 (BayerAG), 1.5% acid blue dye 90 (Orient Chemical), 3.0% surfactant Tergitol15-S-9 (Union Carbide) , 12.0% ethylene glycol (Aldrich), 79.7% water, 0.1% buffer MES, 0.2% chelating agent EDTA, 0.5% fungicide Proxel GXL (ICI).

[0040] The printing and testing methods are as described in Example 1.

Embodiment 3

[0042] The magenta ink composition of the present embodiment comprises: 1.5% directness blue dye 199 (Bayer AG), 1.5% acid blue dye 9 (Orient Chemical), 1.5% acid blue dye 90 (Orient Chemical), 3.0% surface Active agent Tergitol 15-S-9 (Union Carbide), 12.0% ethylene glycol (Aldrich), 79.7% water, 0.1% buffer MES, 0.2% chelating agent EDTA, 0.5% fungicide Proxel GXL (ICI).

[0043] The printing and testing methods are as described in Example 1.

Abstract

The present invention discloses a nautic blue combined colorant for ink jet printing. Said nautic blue dyes composition mainly contains acid blue dyes 90 and matches it with copper phthalocyanine blue dyes mutually. Said invented neutic blue combined colorant has good water-proofing property, can obtain excellent printing quality.

Description

field of invention [0001] The present invention relates to a magenta combined coloring material used in inkjet printing, and to a magenta and color inkjet ink composition containing the combination of the coloring material. Background of the invention [0002] For a color inkjet printer, it usually includes magenta ink, cyan ink, yellow ink and black ink, a total of four color inks. However, in recent years, light-color series inks, such as light magenta, light cyan, and light yellow, have appeared in the field of inkjet printing. This invention also makes In the inkjet printing technology, the color performance is more abundant. Most of these inks are composed of water-based dyes. The so-called water-based dyes have better compatibility with water, so that the fastness to water is greatly reduced. As a result, the waterproof performance of the printed image is very poor; in addition, the dye is also poor in light resistance, which makes the image f...
