Patent ID: 7303618

Claim:
An ink for ink-jet recording comprising a thiazole-based compound, C. I. Direct Blue 199 and a dye (1) represented by the general formula (1): wherein, in the general formula (1), Pc(Cu) represents a copper phthalocyanine nucleus represented by the general formula (2), wherein, in the general formula (1), k is a number satisfying 0<k<8; l is a number satisfying 0<l<8; m is a number satisfying 0≦m<8; n is a number satisfying 0≦n<8; k, l, m and n satisfy 4≦k+l+m+n≦8; and R 1 , R 2 , R 3 and R 4 each independently represent a substituent selected from the group consisting of —SO 2 —R a , —SO 2 NR b R c , and —CO 2 —R a , provided that R 1 , R 2 , R 3 and R 4 are not simultaneously the same, that at least one of R 1 , R 2 , R 3 and R 4 has an ionic hydrophilic group as a substituent, and that at least one or more of R 1 , R 2 , R 3 and R 4 is present on each of four benzene rings A, B, C and D of the copper phthalocyanine nucleus represented by the general formula (2), wherein R a represents a substituted or unsubstituted alkyl group; R b represents a hydrogen atom, or a substituted or unsubstituted alkyl group; and R e represents a substituted or unsubstituted alkyl group, wherein about 1 mol % to about 20 mol % of total counter ions in the C. I. Direct Blue 199 and the dye (1) are ammonium ions or organic ammonium ions.
