    Abstract: 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.

    Abstract: An ink that realizes excellent recorded matter fixation and excellent ink stability and reliability, enabling stable production of recorded matter with high image quality; recorded image; a method of inkjet recording; and an apparatus in which the above ink is used. There is provided a water base ink containing micromicelles dispersed in transparent single phase in water, characterized in that the micromicelles are those composed of a mixture of two or more types of surfactants brought into clouded or semitransparent dispersion form in water and an alkyl having compound wherein the water dissolution group is only hydroxyl. There are further provided, utilizing the same, a method of inkjet recording, apparatus and recorded image.

    Abstract: A recording head and a recording unit in which both reliability for ejection stability and storage stability and suppression of color mixing phenomenon can be satisfied. The recording head has ejection opening arrays for ejecting a plurality of inks constituting an ink set, respectively. The inks are respectively contained in an ink cartridge having an ink containing section which is brought into an enclosed state. Among the plurality of inks, specific gravities of at least three inks are different from one another and the difference in specific gravity of at least two inks is 0.020 or more. The ejection opening arrays are arranged such that the total sum of the differences in specific gravity between each two inks ejected from adjoining ejection opening arrays among the inks ejected from the ejection opening arrays is minimized.

    Abstract: Disclosed is an aqueous ink containing water, a water-insoluble colorant and a plurality of water-soluble organic solvents. The water-soluble organic solvents contain a good solvent and poor solvent for the water-insoluble colorant in a specific ratio, and the water-soluble solvent having the largest Ka value among the water-soluble organic solvents is a poor solvent. When such an aqueous ink is in contact with a specific reactive liquid, the dissolution state or dispersion state of the water-insoluble colorant in the ink is destabilized, thereby having a sufficiently large area factor even with a small amount of ink droplet and enabling to obtain an image which is excellent in the image density, bleed resistance and fixability. This aqueous ink is also excellent in shelf life stability.
