摘要：
A water-based ink-jet recording ink which comprises as major components a water-insoluble dye, water, and a resin and is in the form of an emulsion, characterized by containing at least one yellow dye selected from the group consisting of quinophthalone compounds represented by general formula (1) and pyridone azo compounds represented by general formula (2). It is excellent in light resistance and storage stability. Especially when used as an ink-jet recording ink, the water-based ink can form a high-quality image free from blurring. The image recorded has excellent water resistance.
