  • Publication number: 20240376333
    Abstract: A pretreatment ink that suppresses white spots, suppresses the occurrence of overflow defects from water-based ink, and can produce recorded matter having high image reproducibility. This pretreatment ink, which is coated in advance onto a base material before a water-based ink is coated onto the base material, contains at least a reaction agent, water, and an organic solvent. The organic solvent includes a water-soluble solvent A selected from the group consisting of alkanediols and monools.

  • Publication number: 20240117210
    Abstract: An ink set with which it is possible to effectively prevent bleeding of aqueous ink even in the case when printing takes place at high speed by means of an inkjet discharge recording method. This ink set includes a pretreatment ink and an aqueous ink and is used for a recording method in which the respective inks are discharged on a base material as an inkjet. The respective inks included in said ink set have static surface tensions that satisfy the following relation: static surface tension SP of the pretreatment ink<static surface tension SC of the aqueous ink.
