1. An ink composition comprising a first color material and a second color material,
wherein the first color material is a compound represented by the following Formula (A-I), and the second color material is a compound represented by the following Formula (B-V): wherein, in Formula (A-I), R4's represent a substituent, R5's represent —OR6 or —NHR7, and R6 and R7 represent a hydrogen atom or a substituent, X3 represents a divalent linking group, n0 is 0 or 1, Ar3's represent a divalent heterocyclic group, and Ar4's represent an alkyl group, an aryl group, or a triazine group: wherein, in Formula (B-V), R13's each independently represent a hydrogen atom or a substituent, R14's each independently represent —OR16, —NHR17 or a cyano group, and R16 and R17 represent a hydrogen atom or a substituent, X1 represents a substituted or unsubstituted aryl group, or a substituted or unsubstituted triazine group, n6 is 0 or 1, Ar1's each independently represent a divalent heterocyclic group, and Ar2's each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a triazine group, wherein the content of the first color material in the ink composition is 0.1 or more and 10.0 or less by mass ratio (mass of the first color material/mass of the second color material) relative to the content of the second color material. |
