摘要： An ink for ink jet recording contains a dye and water, a water soluble organic solvent which dissolves the dye, and 0.8 to 5 weight percent of propylene oxide/ethylene oxide block copolymer which has an average molecular weight from 1000 to 5000 and whose content of ethylene oxide group is in the range from 5 to 60 weight percent based on the average molecular weight of the block copolymer. The ink has a surface tension of 30-40 dyne/cm and a viscosity of 1-10 centipoise. An ink jet ink of this invention can be a combination of three colors, e.g., cyan, magenta and yellow, or four colors (adding black to these colors).

摘要： An ink-jet ink contains water, a coloring material and an amine compound represented by the formula: R.sub.1 R.sub.2 R.sub.3 N (I) wherein one or two of R.sub.1, R.sub.2 and R.sub.3 represent(s) (an) alkyl group(s) having 1 to 5 carbon atoms substituted by at least one group selected from the group consisting of a carboxy group, a sulfonic acid group, and a Li, Na, Na, K or ammonium salt thereof, and the remainder represents(s) (an) hydrogen atom(s) or (an) alkyl group(s) having 1 to 5 carbon atoms substituted by a hydroxide group or a carbamoyl group. The pH value of the ink is preferably between 6 to 8. Moreover, printing may be made by applying thermal energy to the ink and forming droplets.The ink and the method of printing using the ink may prevent the change of the amount of ink droplets due to kogation on a heater even with a long-term use, and may not cause a heater trouble due to the corrosion of materials constantly in contact with ink. Further, even if the ink is stored for a long-period, the pH of the ink may be kept to be stable and clogging of print head may be prevented and change of hue of images may be avoided.
