Ink, and recording process making use of it

An ink jet device comprising an ink storing member impregnated with an ink comprising a dye and a liquid medium, wherein said dye is represented by the following Formula (I):

• ##STR10## wherein R.sub.1 and R.sub.2 each represent a hydrogen atom, a methyl group, a methoxy group or --SO.sub.3 M, R.sub.3 and R.sub.4 each represent a methyl group, a methoxy group or an acetylamino group;
• X represents an acetyl group, a benzoyl group;
• --SO.sub.2 C.sub.6 H.sub.5, --SO.sub.2 C.sub.6 H.sub.4 --CH.sub.3, or ##STR11## where R.sub.5 and R.sub.6 each represent a hydrogen atom, or --C.sub.2 H.sub.4 OH;
• and M represents an alkali metal, an ammonium group, or an organic ammonium group;
• and
• a head having a plurality of orifices for discharging said ink as ink droplets.
