Problems solved by technology

[0004] However, on the other hand, various physical properties such as light resistance and water resistance may be poor, resulting in poor light resistance and water resistance of printed matter printed with the dye ink composition.
In terms of water resistance, it can be improved by using inkjet special recording paper with an ink absorbing layer, but it is not enough for ordinary paper

Embodiment

[0056] The present invention will be described in more detail using the following examples, but the present invention is not limited by these examples.

[0057] Adjustment of ink composition

[0058] Each component was mixed according to the composition in Table 1 below, and filtered through a 10 μm membrane filter to prepare each ink. However, the numerical values ​​in the table represent the content (weight basis %) in the ink.

[0059] Table 1

[0060]

[0061] * Dispersant: Styrene-acrylic acid copolymer ammonium salt (molecular weight 7000, resin content 38%)

[0062] Evaluation 1: Color rendering

[0063]For each of the yellow ink compositions obtained in Production Examples Y1 to Y4, the color rendering property was evaluated as follows. Using an inkjet printer PX-A650 (manufactured by Seiko Epson Co., Ltd.), β printing was performed at 100% duty in a size of 5 cm×5 cm on photographic paper (“glossy”, manufactured by Seiko Epson Co., Ltd.). The color develo...

Abstract

The invention provides an ink jet recording combination ink of images, which realizes light resistance and water resistance, but also realizes favorable images, particularly to favorable color. The ink jet recording combination ink includes a cyan ink combination, a fuchsin ink combination and a yellow ink combination, wherein the cyan ink combination is made by selecting at least one dye from a group composed of C.I. dye blue 15:3 and C.I. dye blue 15:4 as a colorant, while the fuchsin ink combination is made by selecting at least one dye from a group composed of C.I. dye red 122, C.I. dye red 202, C.I. dye red 209 and C.I. dye purple 19 as a colorant, and the yellow ink combination is made of C.I. dye yellow 213.

Description

technical field [0001] The present invention relates to an ink set containing a cyan ink composition, a yellow ink composition, and a magenta ink composition used in an inkjet recording method, and the combination of the reaction liquid and the ink An inkjet recording method in which a substance is attached to a recording medium for printing. Background technique [0002] The inkjet recording method is a printing method in which a droplet of an ink composition is leaped and attached to a recording medium such as paper to perform printing. This method is characterized in that high-resolution, high-grade images can be printed at high speed with a relatively inexpensive device. [0003] Ink compositions used in inkjet recording generally contain water as a main component, and contain a coloring component and a humectant such as glycerin for preventing clogging and the like. As the coloring agent used in the ink composition for inkjet recording, water-soluble dyes are often us...
