Abstract
There is provided an ink composition which at least contains a first color material and a second color material, in which the first color material is a compound represented by Formula (A-I) described in the specification, and the second color material is at least one compound selected from a compound represented by Formula (B-I) described in the specification and a compound represented by Formula (B-V) described in the specification.
Claims11
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.
