<P>PROBLEM TO BE SOLVED: To provide a photo-curable inkjet ink which exhibits the inhhibited bleeding of the photopolymerization initiator, decomposition products of the initiator, the sensitizer and other compositions and can prevent the deterioration of the low odor-emission property, the hardness of the cured films and the curability. <P>SOLUTION: The photo-curable inkjet ink comprises a monomer, a pigment and a photopolymerization initiator expressed by general formula (1). In the general formula (1), R<SP>1</SP>-R<SP>4</SP>are each independently an alkyl group, an aryl group and the like; X is a 4-16C divalent condensed aromatic ring group optionally containing a hetero atom. <P>COPYRIGHT: (C)2008,JPO&INPIT |
