Title:
INK SET AND INK JET RECORDING METHOD
Document Type and Number:
Japanese Patent JP2016141693
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ink set, even in the case a blue ink using C.I. pigment violet 23 and an ink using carbon black are jointly used, capable of recording an image in which the reduction of image clarity and the generation of the unevenness in the concentration in a color-mixed part are suppressed.SOLUTION: Provided is an aqueous ink set having a combination of the first ink and the second ink. The first ink and the second ink respectively include a resin dispersant, a water soluble urethane resin, a water soluble organic solvent A having a dielectric constant of 40.0 or more and a water soluble organic solvent B having a dielectric constant of below 40.0. The first ink further includes carbon black having a BET specific surface area of 50 to 240 m/g, further, the second ink further includes C.I. pigment violet 23, and the content A(mass%) of the water soluble organic solvent A in the first ink is lower than the content A(mass%) of the water soluble organic solvent A.SELECTED DRAWING: None
