Claims17
A coloring composition comprising:
- at least one compound S selected from a compound S-1 represented by Formula (1) or a compound S-2 in which the compound S-1 is coordinated to a metal atom;
- a pigment;
- a resin;
- and
- a solvent,
- in Formula (1), R1 represents a hydrogen atom, an alkyl group, or an aryl group, R2 to R9 each independently represent a hydrogen atom or a substituent, and two adjacent groups among R2 to R9 may be bonded to each other to form a ring,
- provided that at least one of R2 to R9 includes a group represented by Formula (R-1),
- —W1—(X1)n (R-1)
- in Formula (R-1), W1 represents an (n+1)-valent linking group, X1 represents an acid group or a basic group, and n represents an integer of 1 to 5,
- when X1 in Formula (R-1) represents a basic group, at least one of R2 to R9 includes the group represented by Formula (R-1), and
- when X1 in Formula (R-1) represents an acid group, at least one of R6 to R9 includes the group represented by Formula (R-1).
