<p>PURPOSE:A novel recording solution useful for ink jetting recording method, having prolonged use life of recording head, extremely reduced trouble ratio of head, and raised reliability, containing a specific compound. CONSTITUTION:The desired recording solution containing 5wt% compound (e.g., compound shown by the formula II, formula III, etc.) shown by the formula I [Q1 and Q4 are (substituted)phenyl, or substituted naphthyl; Q2 and Q3 are (substituted)phenylene or substituted naphthylene; the substituent group is -NH2, -OH, -CH3, -C2H5, -Cl, -Br, -SO3M, -SO2NH2, -SO2NHCH3, -NO2, or -COOM' (M and M' are Na, K, Li, ammonium, or amine)] as a recording agent for forming a recorded image. For example, the compound shown by the formula I is dissolved in water or a mixture of water and 20-50wt% water-soluble organic solvnt (e.g., diethylene glycol, etc.) and used.</p> |
