摘要： A water base ink for ink-jet recording contains self-dispersible carbon black as a coloring agent. The total content of an organic acid having a number of carbon or carbons of 1 to 6 and a salt of the organic acid is not more than 400 ppm. The organic acid having a number of carbon or carbons of 1 to 6 includes monocarboxylic acid, dicarboxylic acid and oxy acid, and the salt of the organic acid includes salts of these acids. When the water base ink is used in an ink-jet recording apparatus, the discharge stability of the ink is improved.

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 includes carbon black as a coloring agent and water. The content of chlorine ion contained in the ink is not more than 8 ppm. The ink may be added with 1,2,3-benzotriazole as a rustproofing agent. Even when oxygen is contained in an amount of about 9 ppm in the ink, the corrosion of a discharge section, which would be otherwise caused by chlorine ion, can be avoided even in the case of the use for a printer which uses a metal member for the discharge section.
摘要翻译：用于喷墨记录的水基油墨包括作为着色剂的炭黑和水。墨中含有的氯离子的含量为8ppm以下。油墨可以加入1,2,3-苯并三唑作为防锈剂。即使在油墨中含有约9ppm的氧气的情况下，即使在使用金属构件的打印机的情况下也可以避免由氯离子引起的排出部的腐蚀用于放电部分。

摘要： The present disclosure relates to an ink-jet ink set which, in spite of using a black ink including a black pigment, may form printed matter (e.g., images) with desirable fixability to glossy paper, color balance after fading (fading stability), and/or water resistance and/or ink-jet ink sets with desirable storage stability. An ink set may include a yellow dye ink including a yellow dye, a magenta dye ink including a magenta dye, a cyan dye ink including a cyan dye and a black ink. A black ink may include a black pigment, a yellow dye, a magenta dye and a cyan dye. A black ink may have a weight ratio of the amount of the black pigment to the total amount of the yellow dye, the magenta dye, and the cyan dye of from about 30/70 to less than about 70/30 (e.g., from about 30/70 to about 70 (but not inclusive of 70)/30).

摘要： A water-based ink set for ink-jet recording is provided. According to this ink set, graininess in a low density printed part can be reduced without reducing a color reproduction range in red and magenta directions in a high density printed part. In addition, the color reproduction range in the red direction can be extended to improve the vividness of red color. The water-based ink set for ink-jet recording includes a magenta ink and a red ink. The magenta ink is a light magenta ink having a lightness (L*) of about 50 or more in the L*a*b* colorimetric system. Preferably, the ink set further includes a light cyan ink having a lightness (L*) of about 60 or more and a blue ink and/or a green ink.
