发明名称 Ink-jet recording ink, ink color set, and ink-jet recording method
摘要 Provided is magenta ink that satisfies all the necessary properties including good light-fastness, good color reproducibility, especially good color reproducibility of magenta-related secondary colors of red and blue, and high reliability, and gives satisfactory high-quality images. Also provided are a color ink set for ink-jet recording, which contains the magenta ink, and an ink-jet recording method in which is used the magenta ink or the color ink set. The magenta ink contains water, a colorant and at least two water-soluble organic solvents, and its visible-light absorbance spectrum gives a first peak A (abs.) within a range of from 500 to 570 nm and a second peak B (abs.) within a range of from 300 to 350 nm with a ratio A/B falling between 0.9 and 2.5. The magenta ink is combined with cyan ink and yellow ink to form the color ink set, which contains water, colorants and at least two water-soluble organic solvents.
