<p>PURPOSE:A recording solution useful especially for ink jetting method utilizing heat energy, having thermally high solubility stability and recording stability, and prolonged life of recording head, containing a compound having a specific structure. CONSTITUTION:0.5-20wt% compound shown by the formula (R1 is H, OH, or NH2; R2 is H, or SO3M; R3 and R4 are H, OH, NH2, NO2, or SO3M; R5 is H, OH, NH2, or SO3M; R6 is H, or SO3M; R7 and R8 are H, NH2, or SO3M; at least one of R5, R6, R7, and R8 is SO3M; M is alkali metal, ammonium, or amine) based on a recording solution is blended with 5-95wt% water and water- soluble organic solvent (e.g., diethylene glycol, etc.) as liquid medium components based on the recording solution, and, if necessary, a viscosity modifier, surface active agent, surface tension adjustor, etc., to give the desired recording solution.</p> |
