Title:

ACTIVE-RAY-CURABLE INKJET RECORDING METHOD

Document Type and Number:

WIPO Patent Application WO/2016/199589

Kind Code:

A1

Abstract:

Provided is an active-ray-curable inkjet recording method comprising: a discharge step for discharging, by an inkjet printing system, an ink composition including a polymerizable compound and a radical polymerization initiator having a weight-average molecular weight of 500-100,000 and a molar absorption coefficient of at least 500 L/(cm·mol) for UV rays having a wavelength of 300 nm; and a curing step for curing the discharged ink composition by irradiating the same with UV rays from an LED light source having a peak between the wavelengths of 275-310 nm in an atmosphere having an oxygen concentration of 5 vol% or less.
