摘要:
A water base ink for ink-jet recording, which is usable for an ink-jet recording apparatus having an ink-jet head provided therein with an ink flow passage formed of nickel or nickel alloy, includes a coloring agent, water, and a water-soluble organic solvent. The ink is blended so that a current density, which is obtained within an electric potential range of −600 to +300 mV, is not more than 100 &mgr;A/cm2 when anodic polarization measurement is performed by using a reference electrode of silver/silver chloride, a counter electrode of platinum, and a working electrode of nickel or nickel alloy. The ink does not corrode any part for constituting the flow passage in the ink-jet head.

摘要:
An ink-jet water-based ink set comprises a black ink and a yellow ink. The black ink contains a black dye, barium hydroxide, and purified water. The yellow ink contains a yellow dye, ammonium chloride, and purified water. When these inks are used to produce liquid drops and to record images on a recording medium with the aid of an on-demand recording head, the barium hydroxide and ammonium chloride initiate an endothermic reaction, whereby color intermixing is reduced, and adequate spraying stability is obtained.
摘要:
A water base ink for ink-jet recording is provided, which makes it possible to secure a high recording quality with a sharp image area edge by avoiding any blurring even when recording is performed on regular paper and which has satisfactory purge restoration performance. Therefore, no bubble remains in an ink flow passage, and no discharge failure is caused. Further, the discharge operation never becomes unstable. In the water base ink for ink-jet recording, the surface tension is not less than 40 mN/m, and the amount of dissolved oxygen is not more than 4 mg/L.
摘要:
A water base ink for ink-jet recording comprises water, a coloring agent, a water-soluble organic solvent, and a benzotriazole-based metal-inactivating agent and alkanolamine. When the ink is used in an ink-jet recording apparatus which has the metal member containing nickel or nickel alloy in an ink supply passage, nickel is eluted from the metal member in an amount of not more than 50 ppm. The ink makes it possible to perform stable jetting operation for a long term without causing any deterioration of metal members of a discharge head due to the metallic corrosion and the elution of nickel into the ink.
摘要:
A set comprising recording inks, with which the color bleed is reduced even when recording is performed on regular paper, is provided. The ink set for ink-jet recording comprises a black ink and a color ink, wherein each of the black ink and the color ink contains at least water, a coloring agent, and a water-soluble organic solvent, the water-soluble organic solvent contained in the black ink has a solubility parameter which is different by not less than 4 from a solubility parameter of the water-soluble organic solvent contained in the color ink, and the water-soluble organic solvent is contained abundantly in an amount next to an amount of water in each of the inks.
摘要:

摘要:
A water base ink for ink-jet recording contains an amine compound selected from the group consisting of N-n-butylethanolamine, 1,4-bis(3-aminopropyl)piperazine, benzylamine, and an amine compound represented by a specified structural formula, a surfactant having a specified structural formula, a coloring agent, and water. It is possible to obtain a satisfactory rub resistance and a high printing quality with a sharp outline without causing any feathering on a recorded image. Further, it is possible to obtain a long term nozzle discharge stability by suppressing any corrosion on a metal member of a discharge head unit of an ink-jet recording apparatus.
摘要:
An ink for ink-recording is provided, which makes it possible to reduce color bleed while suppressing even when recording is performed on regular paper. The ink for ink-jet recording contains water, a coloring agent, a water-soluble organic solvent, and a compound represented by the following general formula (1): wherein R represents a alkyl group having a number of carbons of 8 to 18, and x+y is not more than 10. A surface tension of the ink is controlled to 31 to 35 mN/m, which can reduce color bleed and feathering.
