Patent ID: 7776144

Claim:
A yellow ink for inkjet recording, which comprises: an aqueous medium; and at least two dyes, wherein the at least two dyes each independently has: a λmax of from 390 nm to 470 nm; a ratio of I (λmax+70 nm) to I (λmax) of 0.4 or less, wherein 1(λmax+70 nm) represents an absorbance at a wavelength of λmax+70 nm and I(λmax) represents an absorbance at a wavelength of λmax; and an oxidation potential higher than 1.0 V versus SCE, and wherein at least one of the at least two dyes is a dye represented by formula (Y1): (A 11 -N═N—B 11 ) n -L wherein A 11 and B 11 each independently represents a heterocyclic group that may be substituted; n is 1 or 2; and L represents a hydrogen atom, a monovalent substituent, a single bond, or a divalent linking group, provided that when n is 1, L is a hydrogen atom or a monovalent substituent, and A 11 and B 11 are both monovalent heterocyclic groups; and when n is 2, L is a single bond or a divalent linking group, A 11 is a monovalent heterocyclic group, and B 11 is a divalent heterocyclic group; and wherein at least one of the at least two dyes is a dye represented by formulae (Y2) or (Y3): P—N═N-Q (Y2) wherein, P represents an aryl group that maybe substituted; and Q represents a heterocyclic group that may be substituted, X—N═N—Y (Y3) wherein, X and Y each represents an aryl group that may be substituted.
