To provide: a pretreatment solution for water-based pigment inkjet printing, which has excellent adhesion to ink non-absorbent media and can form a printed material with good print image quality without blotting between inkjet ink droplets; and an ink set comprising the pretreatment solution and a water-based inkjet ink.SOLUTION: A treatment solution for use in a recording method implemented with a water-based inkjet ink at least contains water, an aggregating agent that aggregates components of the ink, and an organic compound. The organic compound contains a compound selected from compounds represented by the shown or other specific chemical formulas, satisfying prescribed conditions.SELECTED DRAWING: None 【課題】インク非吸収性メディアに対する密着性に優れ、インクジェットインク液滴同士で滲みが起こらずに、印刷画質が良好な印刷物を得ることができる、水性顔料インクジェット印刷用の前処理液、及び前記前処理液と水性インクジェットインクを含むインクセットの提供することを課題とする。【解決手段】水系インクジェットインクを用いて行う記録方法に用いる、処理液であり、前記処理液は、少なくとも、水と、インクの成分を凝集させる凝集剤、有機化合物と、を含有する。前記有機化合物は、下記他特定の化学式で表される化合物から選択される化合物を所定の条件を満たして含む。TIFF2024058039000018.tif1579TIFF2024058039000019.tif1175TIFF2024058039000020.tif1370【選択図】なし
