Patent ID: 8710123

Claim:
An ink for inkjet recording comprising an ink composition comprising a polymerizable compound, a polymerization initiator, a pigment and an oil-soluble dye, wherein the pigment and the oil-soluble dye are in any combination of a yellow pigment and a yellow oil-soluble dye, or a magenta pigment and a magenta oil-soluble dye, wherein the yellow oil-soluble dye comprises at least one compound selected from compounds represented by the following formulas (I-1), (II) and (III): wherein in the formula (I-1), W, Y 1 , Y 2 and R 1 to R 4 are each independently a hydrogen atom or a monovalent substituent; R 5 to R 8 are each independently an alkoxycarbonyl group; and X 1 and X 2 are each independently a monovalent electron-withdrawing group having a Hammett's σp value of 0.20 or more; wherein in the formula (II), R 11 , R 13 and R 14 are each independently an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group or an unsubstituted or substituted heteroaryl group, and R 12 and R 15 are each independently a hydrogen atom or a monovalent substituent, wherein R 13 and R 14 may be linked to each other to form a 5- or 6-membered hetero ring; and Z 1 , Z 2 , Z 3 and Z 4 are each independently a hydrogen atom or a monovalent substituent, wherein Z 1 and Z 2 , and Z 3 and Z 4 may be linked to each other to form a 5- or 6-membered ring; wherein in the formula (III), R 11 , R 12 , R 13 , R 14 and R 15 are each independently a hydrogen atom or a monovalent substituent; and R 16 and R 17 are each independently an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group or an unsubstituted or substituted heteroaryl group, and may be linked to each other to form a ring; wherein the magenta oil-soluble dye comprises a compound represented by the following formula (IV-1): wherein in the formula (IV-1), Z 1 is a cyano group; Z 2 is an isopropyl group or a t-butyl group; R 1 is a hydrogen atom; R 2 is an alkyl group having 1 to 4 carbon atoms; R 3 and R 4 are each independently an alkyl group, an aryl group, a heterocyclic group, a sulfonyl group or an acyl group; a and e are each an alkyl group which may be substituted, wherein the number of carbon atoms of a+e is 2 or more; b, c and d are each independently a hydrogen atom, a halogen atom or an alkyl group; and Q is a heterocyclic group.
