Abstract

A water-based ink set includes a yellow ink, a magenta ink, and a cyan ink, each including a coloring agent, water, and a water-soluble organic solvent. The yellow ink includes dyes (Y-1) and (Y-2), the magenta ink includes dyes (M-1) and (M-2), and the cyan ink includes a dye (C-1). Dye (Y-1): a dye represented by the formula (Y-1) Dye (Y-2): at least one dye selected from the group consisting of C. I. Direct Yellow 86, C. I. Direct Yellow 132, and C. I. Direct Yellow 142 Dye (M-1): a dye represented by the formula (M-1) Dye (M-2): at least one dye selected from the group consisting of dyes represented by a formula (M-2a), dyes represented by the formula (M-2b), C. I. Acid Red 1, and C. I. Acid Red 254 Dye (C-1): a dye represented by the formula (C-1).

Description

technical field [0001] The present invention relates to an aqueous ink set for inkjet recording, an ink cartridge and an inkjet recording device. Background technique [0002] Water-based ink sets for inkjet recording are generally required to satisfy the following performances at a high level: (1) Provide vivid images with good color development; (2) Light fastness, reactive gas resistance (NO x , ozone and other oxidizing gases, SO x etc.), excellent fastness such as water resistance; (3) no problem even if it comes into contact with various components used in inkjet recording devices; Sufficient ejection stability is maintained even when the nozzles of the ink head are clogged, etc. [0003] In addition, an ink set containing three color inks of yellow, magenta, and cyan is strongly required to have a hue close to a standard hue and be vivid as a water-based ink set for inkjet recording when expressing natural images through color mixing. In addition, recorded natural ...
