摘要： A water-base jet printing ink comprising a coloring matter and an aqueous medium as the main components, wherein at least one member selected from among dyes of the general formula (A) and salts thereof is contained as the coloring matter (A) [wherein R1 and R3 are each hydrogen, halogeno, or the like; R2 and R4 are each hydrogen, alkyl, or the like; A is phenyl or naphthyl; X is a divalent connecting group; and m and n are each 1 to 4]. It is preferable that a dye represented by the general formula (A) be freed from insolubles by adjusting the pH of an aqueous solution of the dye to 9 or above. The ink does not clog a printer head and enables the formation of high-quality and bleeding-free images.

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.
