<P>PROBLEM TO BE SOLVED: To provide an ultraviolet-curable magenta ink composition having excellent preservation stability (dispersion stability) and jetting properties and obtained by using a magenta pigment. <P>SOLUTION: The ultraviolet-curable magenta ink composition for inkjet printing contains a quinacridone-based pigment, a photopolymerizable compound, a macromolecular dispersant having a basic absorbing group, a photopolymerization initiator, and a quinacridonesulfonic acid-based compound. The composition preferably contains a photopolymerizable compound dissolving the macromolecular dispersant. <P>COPYRIGHT: (C)2004,JPO |
