Title:
ACTIVE RAY-CURABLE INKJET RECORDING METHOD, AND PRINTED MATTER
Document Type and Number:
Japanese Patent JP2018122431
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an active ray-curable inkjet recording method which is excellent in curability of an ink composition to be used and can obtain a printed matter with less yellow discoloration and odor, and to provide a printed matter formed by the inkjet recording method.SOLUTION: An active ray-curable inkjet recording method includes: a discharge step of discharging an ink composition containing a radical polymerization initiator having a molar absorption coefficient in ultraviolet rays having a wavelength of 300 nm of 500 L/(cm mol) or more and a weight average molecular weight of 500-100,000, and a polymerizable compound by an inkjet printing method; and a curing step of irradiating the discharged ink composition with ultraviolet rays by an LED light source having a peak between a wavelength of 275-310 nm under an atmosphere such that oxygen concentration is 5 vol.% or less to cure the ink composition.SELECTED DRAWING: Figure 1
