PROBLEM TO BE SOLVED: To provide a photopolymerizable inkjet ink which is solid at room temperature, which simultaneously achieves low skin sensitivity in addition to quick drying property, high image quality and stable printing aptitude; and to provide an ink cartridge, an inkjet printing process and an inkjet recording device using the ink.;SOLUTION: (1) The photopolymerizable inkjet ink which is solid at room temperature contains a monomer or oligomer whose skin sensitivity is negative, and a wax having a hydrophilic functional group. (2) The ink cartridge accommodates the photopolymerizable inkjet ink which is solid at room temperature. (3) The inkjet printing process includes heating the photopolymerizable inkjet ink which is solid at room temperature to liquefy it and printing it, and photocuring it after ink drops are thickened or solidified on a substrate held at room temperature.;COPYRIGHT: (C)2013,JPO&INPIT
