摘要 |
The invention provides an ink for use in an ink jet recording process in which an ink is ejected from a recording head by the action of thermal energy, comprising a pigment, a water-soluble polyurethane polymer, a compound represented by a general formula (1) having a weight-average molecular weight of 1,000 or more and 8,500 or less, and a polyethylene oxide alkyl ether the alkyl group of which has 12 or more carbon atoms, wherein based on the total mass of the ink the content (mass %) of the compound represented by the general formula (1) is 0.4 times or more and 10.0 times or less in terms of mass ratio with respect to the content (mass %) of the polyethylene oxide alkyl ether. |
