摘要:
A liquid composition which can achieve superior scratch resistance of images at such a level that coloring materials are hardly scraped off even when images are scratched with finger nails under application of such strong pressure as to scratch a recording medium at its non-recorded areas. The liquid composition contains at least a modified siloxane compound having specific structure and a polymer whose acid value and hydrogen bond parameter (δh) are specified.

An ink to be used in an ink jet recording method of ejecting an ink from a recording head through action of thermal energy can improve the ink ejection stability and shows a high storage stability and a high color developability. An ink to be used in an ink jet recording method of ejecting an ink from a recording head through action of thermal energy is characterized in that the ink comprises a pigment represented by the general formula (1), a dispersant, a water-soluble organic compound and an aggregation inhibiting substance for inhibiting aggregation after dispersion breakdown of the pigment, and the content (mass %) of the aggregation inhibiting substance with respect to the total mass of ink is 0.4 times or more to less than 1.3 times of the content (mass %) of the pigment with respect to the total mass of ink.

An ink comprise a dye, a silicon-containing surfactant, an ethylene oxide adduct of acetylene glycol and a liquid medium, wherein a weight ratio of the silicon-containing surfactant to the ethylene oxide adduct of acetylene glycol is not lower than {fraction (1/5000)}, but lower than {fraction (1/20)}. An ink-jet recording process include the step of ejecting the ink by an ink-jet system. An ink set include in combination a first dye having a certain color tone, and a second dye ink having a color tone different from that of the first dye ink, wherein at least one of the first and second dye inks is the above ink. An ink set include dye inks of yellow, magenta and cyan, wherein the dye inks include an ethylene oxide adduct of acetylene glycol respectively, and the dye inks of magenta and cyan further have a silicon-containing surfactant.

摘要:
The present invention relates to aqueous ink that exhibits characteristics based on cationic self-dispersing carbon black, and that has superior ejection stability even after suspension of printing. The aqueous ink includes cationic self-dispersing pigment, in which at least one cationic group is bound to the surface of the pigment directly or with another atomic group therebetween, a water-soluble organic solvent, and water. In addition to this, the aqueous ink contains an acidic compound including a proton in the structure thereof that can be dissociated due to dissolution into water, and having a dissociation stage of the proton with a dissociation constant of less than 1.
