Abstract
To reduce the viscosity of a coloring composition containing a pigment.SOLUTION: The coloring composition contains a compound represented by formula (I), and a pigment. [In formula (I), L1 represents a group represented by formula (ph1); R1 to R4 each independently represent a hydrogen atom, a hydrocarbon group that may have substituents, a heterocyclic group, -SO3 N(R5)4, a cyano group, or a halogen atom, provided that at least one of R1 to R4 is -SO3 N(R5)4, or a hydrocarbon group having one or more -SO3 N(R5)4 groups as substituents; and R5 represents a hydrogen atom or a hydrocarbon group, where multiple occurrences of R5 may be identical or different.]SELECTED DRAWING: None
