  • Patent number: 10457821
    Abstract: An aqueous inkjet ink includes at least water, a coloring material, a water-soluble organic solvent component, a surfactant, and resin microparticles. The water-soluble organic solvent component includes a first monool-type solvent represented by R1O(CH2CH2O)mH in which R1 represents a straight or branched alkyl group having 1 to 4 carbon atoms, and m represents an integer of 2 or 3, a second monool-type solvent represented by R2O(C3H6O)nH where R2 represents a straight or branched alkyl group having 1 to 4 carbon atoms, and n represents an integer of 2 or 3, and a third monool-type solvent that is at least one selected from the group consisting of 3-methoxy-1-butanol and 3-methoxy-3-methyl-1-butanol. The content of the third monool-type solvent in the ink is about 8% by mass or greater and about 27% by mass or less. The content of the first monool-type solvent in the ink is about 0.5% by mass or greater and about 9% by mass or less. The content of the second monool-type solvent in the ink is about 0.

  • Patent number: 10214034
    Abstract: An inkjet recording device allows a recording medium to be set easily, and prevents the recording medium from being warped so that printing quality is not lowered. An inkjet printer includes a bed including a surface that supports a recording medium, and a pivoting device that pivots the bed around a horizontal axis to locate the bed horizontally or vertically or pivots the bed around the horizontal axis to incline the bed with respect to a horizontal plane. The inkjet printer also includes a pair of guide rails provided on the bed and extending in an X direction and a movable member extending in a Y direction, engaged with the pair of guide rails and slidable on the pair of guide rails to move in the X direction.

  • Publication number: 20180118965
    Abstract: An aqueous inkjet ink includes at least water, a coloring material, a water-soluble organic solvent component, a surfactant, resin particles, and a water-soluble carbodiimide compound that acts as a crosslinking component. The surfactant is a silicone-based surfactant. The resin microparticles include a functional group reactive with a carbodiimide group at least at a surface thereof. A mass ratio of the resin microparticles with respect to the water-soluble carbodiimide compound is about 10 or greater.
