Abstract: Disclosed herein is a pigment ink comprising self-dispersing type carbon black to the surface of which at least one hydrophilic group is bonded through another atomic group, an aqueous medium, and a silicon compound. The pigment ink can form images excellent in fastness properties such as water fastness and light fastness and character quality, can be efficiently ejected when applied to ink-jet recording and can also be stably ejected from a recording head irrespective of recording head and printing environment.

Abstract: A water base ink comprising water, multiple water soluble organic solvents o f different types and a water insoluble color material, wherein the multiple water soluble organic solvents comprises a good solvent for the water insoluble color material and a poor solvent for the water insoluble color material, wherein providing that A represents the total amount (mass%) of go od solvent in the ink while B represents the total amount (mass%) of poor solve nt in the ink, the ratio of A:B is in the range of 10:5 to 10:30, and wherein upon comparison of the respective Ka values, determined in accordance with t he Bristow method, of the multiple water soluble organic solvents, the water soluble organic solvent exhibiting the maximum Ka value is a poor solvent. With respect to pigment inks, images of high OD having a satisfactorily larg e area factor even with a small amount of ink drop can be obtained.

Abstract: A fiber body which exhibits sufficient ink supplying characteristics for keeping up with the trend toward diversification of ink and high printing speed while ensuring an easy and simple ink injection operation and a liquid container having the same. The ink tank 1 has a PP fiber body (crosshatched area of the figures) 2, as a negative pressure generating member for an ink jet head which ejects liquid to perform recording, arranged almost all over the interior thereof, so as to allow the fiber body to hold a liquid to be supplied to an ink jet head. On the top of the tank casing, provided is an atmosphere communication port 3. And as a PP fiber body 2, used is an assembly of intertwined PP fibers of which surface has been subjected to surface treatment of giving hydrophilic nature thereto.
