Abstract: A coloring liquid can form an image showing a high color developability and a high vividness as well as an excellent water fastness when used as recording material with a recording technique such as ink-jet printing. An ink tank, a recording unit, a recording apparatus and a recording method are adapted to use such a coloring liquid. Such a coloring liquid contains at least one colorant compound having a structure represented by the general formula (1) below and an ink tank, a recording unit, a recording apparatus and a recording method are adapted to use such a coloring liquid.

Abstract: There is provided a colorant material comprising a compound represented by at least one of the following general formulas (1) and (2) as a first colorant compound and at least one of a water insoluble triphenylmethane compound and a water insoluble xanthene compound as a second colorant compound
