R 11 to R 15 each independently represent a hydrogen atom or a substituent, and
Y 1 and Y 2 each independently represent a hydrogen atom or a substituent,
where at least one of R 11 or R 14 is a substituent, and
wherein at least one of R 11 to R 15 is a group represented by Formula (R-100):
*-L R1 -(X R1 ) n   (R-100)

wherein, in Formula (R-100), L R1 represents an aliphatic hydrocarbon group, an aromatic hydrocarbon group, a heterocyclic group, —O—, —S—, —NR L1 —, —CO—, —COO—, —OCO—, —SO 2 —, or an (n+1)-valent linking group consisting of a combination of these groups; R L1 represents a hydrogen atom, an alkyl group, or an aryl group; X R1 represents an acid group or a basic group; n represents an integer of 1 or more; and, in a case where n is 1, L R1 may be a single bond.

2 . The composition according to claim 1 ,
wherein one of R 1 and R 2 in Formula (1) is a cyano group and the other is an aryl group or a heteroaryl group, and one of R 3 and R 4 in Formula (1) is a cyano group and the other is an aryl group or a heteroaryl group.

3 . The composition according to claim 1 ,
wherein Y 1 and Y 2 in Formula (1) each independently represent —B(boron)R Y1 R Y2 , where R Y1 and R Y2 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, or a heteroaryloxy group, and R Y1 and R Y2 may be bonded to each other to form a ring.

4 . The composition according to claim 1 ,
wherein the coloring agent represented by Formula (1) has a maximal absorption wavelength at a wavelength of 650 nm or more.

5 . The composition according to claim 1 , further comprising:
a compound represented by Formula (Pc),

in Formula (Pc), Rp 1 to Rp 16 each independently represent a hydrogen atom or a substituent,
at least one of Rp 1 or Rp 4 represents an alkyl group,
at least one of Rp 5 or Rp 8 represents an alkyl group,
at least one of Rp 9 or Rp 12 represents an alkyl group,
at least one of Rp 13 or Rp 16 represents an alkyl group, and
M 1 represents two hydrogen atoms, a divalent metal atom, or a divalent substituted metal atom including a trivalent or tetravalent metal atom.

6 . A film formed of the composition according to claim 1 .

7 . An optical filter comprising:
the film according to claim 6 .

8 . A solid-state imaging element comprising:
the film according to claim 6 .

9 . An image display device comprising:
the film according to claim 6 .

10 . An infrared sensor comprising:
the film according to claim 6 .

11 . A camera module comprising:
the film according to claim 6 .

12 . A compound represented by Formula (1),

in Formula (1), R 1 to R 4 each independently represent a substituent,
R 5 represents an alkyl group,
R 11 to R 15 each independently represent a hydrogen atom or a substituent, and
Y 1 and Y 2 each independently represent a hydrogen atom or a substituent,
where at least one of R 11 or R 14 is a substituent, and
wherein at least one of R 11 to R 15 is a group represented by Formula (R-100);
*-L R1 -(X R1 ) n   (R-100)

wherein, in Formula (R-100), L R1 represents an aliphatic hydrocarbon group, an aromatic hydrocarbon group, a heterocyclic group, —O—, —S—, —NR L1 —, —CO—, —COO—, —OCO—, —SO 2 —, or an (n+1)-valent linking group consisting of a combination of these groups; R L1 represents a hydrogen atom, an alkyl group, or an aryl group; X R1 represents an acid group or a basic group; n represents an integer of 1 or more; and, in a case where n is 1, L R1 may be a single bond.
