Abstract

See full text

Provided are an actinic energy radiation curable ink, which can achieve a high fineness and natural glossiness when recording is carried out onto a non-absorptive recording medium such as a film or a laminated paper or a slightly absorptive recording medium such as a coated paper; and an actinic energy radiation curable inkjet recording method. This actinic energy radiation curable ink, which is to be used in inkjet recording, is characterized by: said actinic energy radiation curable ink undergoing reversible sol/gel phase transition depending on temperature; said actinic energy radiation curable ink containing from 1% or more by mass to less than 10% by mass of a gelling agent; and, at temperature Tm (° C.) that is separately defined, the storage elastic modulus (G′) of the actinic energy radiation curable ink being from 0.1 or more Pa to less than 1000 Pa and the storage elastic modulus (G′) being smaller than the loss elastic modulus (G″) thereof.
