ABSTRACT:
An ink composition of the present invention is disclosed, which contains (i) a sensitizing dye represented by the following Formula (I); (ii) at least one polymerization initiator selected from the group consisting of α-aminoketones and acyl phosphine oxides; and (iii) an ethylenically unsaturated bond-containing polymerizable compound. In Formula (I), X represents O, S or NR; n represents an integer of 0 or 1; R represents a hydrogen atom, an alkyl group or an acyl group; R1to R8each independently represent a hydrogen atom or a monovalent substituent; R1and R2, R2and R3, and R3and R4may be connected to each other to form a ring; and R5or R6may be connected to R7or R8to form an aliphatic ring but not to form an aromatic ring.
