Abstract
An ink composition for ink jet recording comprising a dye, 1 to 10% by weight of glycerin, 1 to 5% by weight of a monohydric alcohol having 4 or less carbon atoms, 0.5 to 10% by weight of 1,3-dimethyl-2-imidazolidinone and 75 to 95% by weight of water. The ink composition of the present invention can offer a good balance of properties required of the ink jet recording ink, especially quality of the print, dryability of the print, water-resistance of the print, storage stability and a property that does not attack members constituting a recording head and an ink passage.
