<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable ink for inkjet recording which shows excellent curability with little irradiation of the energy ray irrespective of the thickness of a coat film and which does not cause ununiformity of the curing. <P>SOLUTION: The active energy ray curable ink for inkjet recording comprises a colorant, a compound containing an ethylenic double bond, and a photopolymerization initiator. The photopolymerization initiator contains a compound represented by general formula (1) and an α-aminoketone compound or an acylphosphine oxide compound. The amount of the compound represented by general formula (1) is ≥40% by mass of a total of the photopolymerization initiators. In the formula, A represents one selected from the group consisting of -O-, -CH<SB>2</SB>-, -CH(CH<SB>3</SB>)- and -C(CH<SB>3</SB>)<SB>2</SB>-, and R<SP>1</SP>and R<SP>2</SP>independently represent a hydrogen atom, a methyl group or a trimethylsilyl group. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
