INKJET RECORDING METHOD AND INKJET RECORDING APPARATUS

摘要

An inkjet recording method using an active light-curable inkjet ink according to the present invention is characterized in that: the inkjet ink contains at least a gelling agent, a photopolymerizable compound and a photopolymerization initiator; the gelling temperature T1 (° C.) of the active light-curable inkjet ink, the temperature T2 (° C.) of the ink at the time when the active light-curable inkjet ink landed on a recording medium, and the temperature T3 (° C.) of the ink at the time when the active light-curable inkjet ink is irradiated with active light satisfy the relationship T1 (° C.)>T2 (° C.)>T3 (° C.); and the solubility of the gelling agent in the photopolymerizable compound at T3 (° C.) is less than 0.1% by mass. This inkjet recording method is capable of suppressing blooming, while at least maintaining the leveling properties and the pinning properties of an inkjet ink.
