摘要：

PURPOSE:To obtain printing which is excellent in quick drying, printing quality and fastness even when recording is performed on plain paper, by a method wherein in a recording method by an ink jet system, ink containing an acidic dye and/or a direct dye and ink containing a basic dye are one upon the other printed. CONSTITUTION:Ink containing an acidic dye and/or a direct dye and ink containing a basic dye are one upon the other printed. As the acidic dye and direct dye to be used, azo series or the like are exemplified. Further, as the basic dye, azo series or the like are exemplified. As contents of an aqueous dye of the acidic dye, direct dye, and basic dye, a range of 0.2-10% to total weight of respective ink is exemplified. Though an aqueous solvent is preferably contained in ink, as said aqueous solvent, for instance, ethylene glycol or the like in addition to water are preferably contained. As the content of the aqueous solvent, a range of 10-89.5wt.% to total weight of respective ink is exemplified. pH of ink to be used is respectively adjusted generally at 6-8.
