Abstract: Provided is an ink jet ink containing a coloring material having a buffer region in an ink use range, the ink jet ink being capable of suppressing the occurrence of the deterioration (dissolution) of a heating portion surface in contact with liquid; and the disconnection of wiring for applying a voltage to a heating portion even when long term continuous printing is performed. The ink jet ink is used for an ink jet recording apparatus equipped with a recording head having a heating portion surface in contact with liquid comprising a metal and/or a metal oxide. The ink jet ink contains a coloring material in a content (mass%) of 3 mass% or more with respect to the total mass of the ink jet ink. The coloring material is a colorant having a buffer region in an ink use range, and comprises a compound represented by the following general formula (I) and/or a compound represented by the following general formula (II). General formula (II) H(OCH 2 CH 2 ) p R 5

CPC classification number: C09B5/14 , C09D11/328
Abstract: This invention provides an ink for ink jet recording that, even when an ink for ink jet recording containing a colorant having a buffer region in an ink working range is used to perform continuous printing for a long period of time, can suppress a deterioration (dissolution) on a liquid contact face in a heat generating part and can suppress the occurrence of disconnection in wiring for applying voltage to the heat generating part. The ink for ink jet recording is used in an ink jet recording apparatus provided with a recording head having a metal and/or metal oxide-containing heat generating part liquid contact face and has a colorant content (% by mass) of not less than 3% by mass based on the total mass of the ink for ink jet recording. The colorant has a buffer region in an ink working range. The ink further contains a compound represented by general formula (I) and/or a compound represented by general formula (II).
