    摘要： The invention provides a method for preparing an ink having constituents of a water-soluble dye having a water-soluble solubilizing group of at least one of a sulfonic group and a carboxyl group, water, a water-soluble substance that is condensation-polymerized in the absence of the water, a water-soluble medium and an additive including at least one of an organic acid salt and an inorganic acid salt. This method includes a first mixing step of mixing at least the dye and the water-soluble substance out of the constituents of the ink excluding the additive; a second mixing step of mixing a mixture obtained in the first mixing step and the additive; and a pH adjusting step, performed before the second mixing step, of preparing a solution including the mixture or a solution including the additive while adjusting the solution to a given pH range by using a pH adjuster.

    摘要： Changes of ink properties are prevented in an ink jet recording head, an ink cartridge, and a recording apparatus which include ink containing a dye having an anion group, a humectant, a penetrant, water, and a hydrolyzable silane compound having an amino group. Resin or rubber which contains a hydrogen ion releasing additive is used for a member of the apparatus with which ink for ink jet recording comes in contact. The content of the additive in the material is not less than 0.001% by mass and not more than 0.1% by mass. The additive includes at least an acid, a ketone, and a functional group of ester each of which exhibits acidic properties.

    摘要： In an ink for ink jet recording use including a water-soluble dye, a humectant, a penetrant, water and a hydrolyzable organic silicon compound, silicon atoms (62) are contained in the ink at a ratio of 3.3 or more with respect to one hydrophilic group (52) in the water-soluble dye molecules (50) so that at least the whole hydrophilic groups (52) in the water-soluble dye molecules (50) are surrounded by silicon atoms (62) as a result of a condensation and polymerization reaction of said organic silicon compound.
