<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable type ink-jet ink comprising a quinophthalone pigment stably dispersed in a monomer and having excellent jetting stability and preservation stability and to provide prints cured with the active energy ray-curable type ink-jet ink. <P>SOLUTION: The active energy ray-curable type ink-jet ink is characterized as follows. The ink is composed of a polymer dispersing agent, an active energy ray-curable monomer, the quinophthalone pigment and a quinophthalone derivative obtained by reacting the quinophthalone pigment with concentrated sulfuric acid, etc., and containing a sulfonic acid or a salt thereof. <P>COPYRIGHT: (C)2007,JPO&INPIT |
