Abstract
Official abstract text for this publication.
The present invention provides an ink jet ink that is capable of recording an image excellent in light resistance and ozone resistance and has excellent intermittent ejection stability. The ink jet ink contains a coloring material and a water-soluble organic solvent. The coloring material contains a compound represented by the following general formula (I), the water-soluble organic solvent contains ethylene urea end an alkanediol having 4 to 6 carbon atoms, and a content A (% by mass) of the coloring material, a content B (% by mass) of the ethylene urea and a content C (% by mass) of the alkanediol having 4 to 6 carbon atoms based on a total mass of the ink satisfy relationships of 0.20≦B/A≦10.0 and 0.10≦C/A≦10.0.
