Abstract

A coloring composition includes 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

First claim

What is claimed is:

1 . 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), R 1 represents a hydrogen atom, an alkyl group, or an aryl group, R 2 to R 9 each independently represent a hydrogen atom or a substituent, and two adjacent groups among R 2 to R 9 may be bonded to each other to form a ring,
provided that at least one of R 2 to R 9 includes a group represented by Formula (R-1),
—W 1 —(X 1 ) n   (R-1)

in Formula (R-1), W 1 represents an (n+1)-valent linking group, X 1 represents an acid group or a basic group, and n represents an integer of 1 to 5,
when X 1 in Formula (R-1) represents a basic group, at least one of R 2 to R 9 includes the group represented by Formula (R-1), and
when X 1 in Formula (R-1) represents an acid group, at least one of R 6 to R 9 includes the group represented by Formula (R-1).

2 . The coloring composition according to claim 1 ,
wherein the acid group represented by X 1 of Formula (R-1) is a carboxyl group, a sulfo group, a phosphoric acid group, a group represented by —SO 2 NHSO 2 Rf 1 , or a salt of these groups, where Rf 1 represents a group including a fluorine atom, and the basic group represented by X 1 of Formula (R-1) is an amino group or a salt of an ammonium group.

3 . The coloring composition according to claim 1 ,
wherein X 1 of Formula (R-1) is the basic group.

4 . The coloring composition according to claim 1 ,
wherein the compound S-2 is a compound represented by Formula (1a),

in Formula (1a), R 1 represents a hydrogen atom, an alkyl group, or an aryl group, R 2 to R 9 each independently represent a hydrogen atom or a substituent, two adjacent groups among R 2 to R 9 may be bonded to each other to form a ring, and M 1 represents a metal atom which may be coordinated with a ligand, where at least one of R 2 to R 9 includes the group represented by Formula (R-1).

5 . The coloring composition according to claim 4 ,
wherein M 1 in Formula (1a) is a copper atom which may be coordinated with a ligand or a zinc atom which may be coordinated with a ligand.

6 . The coloring composition according to claim 1 ,
wherein the pigment includes at least one selected from a yellow pigment, a green pigment, or a red pigment.

7 . The coloring composition according to claim 1 ,
wherein the pigment includes a pigment having a metal atom.

8 . The coloring composition according to claim 7 ,
wherein the pigment having a metal atom includes an azomethine metal complex.

9 . The coloring composition according to claim 8 ,
wherein the azomethine metal complex includes at least one selected from an azomethine copper complex or an azomethine zinc complex.

10 . The coloring composition according to claim 1 ,
wherein the coloring composition includes the compound S in an amount of 1 to 30 parts by mass with respect to 100 parts by mass of the pigment.

11 . The coloring composition according to claim 1 , further comprising:
a polymerizable compound; and a photopolymerization initiator.

12 . The coloring composition according to claim 1 ,
wherein the coloring composition is used for a color filter or an infrared transmitting filter.

13 . The coloring composition according to claim 1 ,
wherein the coloring composition is used for a solid-state imaging element.

14 . A film obtained from the coloring composition according to claim 1 .

15 . An optical filter comprising:
the film according to claim 14 .

16 . A solid-state imaging element comprising:
the film according to claim 14 .

17 . An image display device comprising:
the film according to claim 14 .
