<p>PROBLEM TO BE SOLVED: To obtain an yellow pigment-based aq. recording liquid for ink jet printers which has a good light resistance and is excellent in chroma and storage stability in spite of contg. specific C.I. pigments (e.g. C.I. Pigment Yellow 185) poor in light resistance. SOLUTION: In an aq. recording liquid used for ink jet printers and contg. fine colored particles formed by coating a pigment with an org. polymer compd. having neutralized anionic groups, C.I. Pigment Yellow 154 and at least one pigment selected from among C.I. Pigment Yellow 185, C.I. Pigment Yellow 180, C.I. Pigment Yellow 139, C.I. Pigment Yellow 138, C.I. Pigment Yellow 110, C.I. Pigment Yellow 109, and C.I. Pigment Yellow 74 are simultaneously contained.</p> |
