Title:
INK-JET RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/137498
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an ink-jet recording method with which it is possible to sufficiently remove air bubbles contained in an actinic-ray-curable ink-jet ink and to heighten the delivery stability and curability of the ink. The ink-jet recording method employs an actinic-ray-curable ink-jet ink which comprises a colorant, a photopolymerization initiator, and a photopolymerizable compound having a molecular weight in the range of 250-1,500. The ink-jet recording method comprises: a step in which the ink-jet ink is introduced into a depressurized space within an ink-jet recorder and deaerated at an ink temperature which is 50°C or higher but lower than 120°C; a step in which droplets of the deaerated ink-jet ink are ejected from the recording head and delivered to a recording medium; and a step in which the ink droplets delivered to the recording medium are irradiated with actinic rays to cure the ink droplets.
