摘要:
A water base ink set for ink-jet recording includes a black ink containing water, a black pigment and a water-soluble organic solvent and a color ink containing water, a dye, and a water-soluble organic solvent. The black pigment is a negatively-chargeable and self-dispersible pigment. The dye has a fluorescein structure. The color ink further contains an alkylamine ethylene oxide adduct. The water-soluble organic solvent contained in the black ink is same as that contained in the color ink. With the ink set, not only the bleeding hardly occurs but also satisfactory discharge stability is obtained even when an ink-jet recording is performed on a regular paper.
摘要:
An ink set for ink-jet recording comprises a pigment ink and a dye ink containing a pigment and a dye as coloring agent, respectively. The pigment ink contains water, a water-soluble organic solvent, and a negatively charged pigment wherein potassium ion and sodium ion have a total ion concentration of not more than 200 ppm, and divalent or multivalent metal ion or ions have a total ion concentration of not more than 10 ppm. The dye ink contains water, a water-soluble organic solvent, and a dye associated with a counter ion of lithium ion wherein potassium ion and sodium ion have a total ion concentration of not more than 400 ppm, and divalent or multivalent metal ion or ions have a total ion concentration of not more than 10 ppm. In the ink set, the pigment and dye inks can be used in combination without complicating a maintenance system.

摘要:
A water base ink for ink-jet recording contains a surfactant represented by the following formula (1) or (2), dipropylene glycol, a coloring agent, and water: CH3—(CH2)11—O—(CH2CH2O)z—H(2) In the formula (1), R represents alkyl group, and x and y represent integers which satisfy x+y=5 to 15. In the formula (2), z represents an integer of not more than 9. The performance of initial introduction into a recording head is satisfactory, and it is possible to simultaneously reduce the feathering and the color bleed even when the recording is performed on regular paper.
