    摘要: An object of the present invention is to provide an ink set which can produce images with color developability undoubtedly higher than images produced by a conventional pigment ink and closer to images produced by silver halide photography or output from a laser printer, in particular, color developability in a red color region, while keeping ink reliability. The ink set comprises at least a first ink and a second ink wherein the first ink has a maximum absorption wavelength in a region of 450 nm or more and less than 500 nm and the second ink has a maximum absorption wavelength in a region of 500 nm or more and 570 nm or less, and the ink set has a B/A ratio of a minimum absorbance B to a maximum absorbance A of 0.7 or more and 1.0 or less among absorbances of the first ink and the second ink in total in a region of 450 nm or more and 570 nm or less.

    摘要: The invention provides an aqueous ink comprising a polymer having hydroxyl groups and a pigment, which can provide images excellent in scratch resistance and highlighter resistance and can inhibit the seeping out phenomenon of the polymer and the deterioration of storage stability and ejection characteristics even when it is stored for a long period of time. The aqueous ink comprises a polymer having hydroxyl groups and a pigment, wherein a proportion of a content of a polymer that is not adsorbed on the pigment out of the polymer having hydroxyl groups to the content of the pigment in the ink is 2.0 mass % or more, and a content (mass %) of the polymer that is not adsorbed on the pigment out of the polymer having hydroxyl groups is 0.20 mass % or less based on the total mass of the ink.
