Recording liquid composition

A recording liquid composition for use in a recording system of the type in which the recording liquid composition is jetted from a small orifice in a form of droplet flying toward a recording material on which an image is to be printed, said recording liquid composition comprising a nitrogen-containing heterocyclic ketone compound and, as its recording agent component, a compound of the general formula (B):

• ##STR10## wherein Q.sub.3 and Q.sub.6 each represents a substituted or unsubstituted phenyl or naphthyl group;
• Q.sub.4 and Q.sub.5 each represents a substituted or unsubstituted 1,4-phenylene or 1,4-naphthlyene group;
• R.sub.5 and R.sub.6 are selected from hydrogen, hydroxyl and amino group;
• R.sub.7 and R.sub.8 each represents hydrogen atom or sulfo group in a form of sodium salt or quaternary ammonium salt;
• X is --NH--, --N.dbd.N-- or --CH.dbd.CH-- and
• n is 0 or 1 provided that when n is 0, Q.sub.4 and Q.sub.5 are not unsubstituted 1,4-phenylene at the same time.

In a ink jet recording process for discharging a recording liquid from a discharge orifice in a recording head and spattering said recording liquid in the form of droplets for recording, the improvement which comprises employing a recording liquid comprising a carrier liquid and a compound of the general Formula B as follows:

• ##STR14## wherein Q.sub.3 and Q.sub.6 each represents a substituted or unsubstituted phenyl or naphthyl group;
• Q.sub.4 and Q.sub.5 each represents a substituted 1,4-phenylene or 1,4-naphthylene group;
• R.sub.5 and R.sub.6 are selected from hydrogen, hydroxyl and amino group;
• R.sub.7 and R.sub.8 each represents hydrogen atom or sulfo group in a form of sodium salt or quaternary ammonium salt;
• X is --NH--, --N.dbd.N or --CH.dbd.CH-- and n is 0 or 1 provided that when n is 0, Q.sub.4 and Q.sub.5 are not unsubstituted 1,4-phenylene at the same time.
