摘要

A recording liquid containing a plurality of water-soluble dyes is provided in which the water-soluble dyes give a tone satisfying the following formula (I) and has a chromatographic characteristic satisfying the following formula (II): 0 + ( DELTA b*)<2> 0 wherein (I), DELTA a* and DELTA b* represent respectively a difference in a* and b* between any two dyes selected from said plurality of dyes in perception chromaticity indexes, and DELTA Rf represents a difference of flow rate Rf in paper chromatography between any two dyes selected from said plurality of dyes. A recording method using the recording liquid is also provided, which is useful for recording onto a recording medium containing a cellulose fiber exposed at the surface of the recording medium.
