Abstract

Provided are a coloring composition capable of producing a film having fewer defects generated, and the like even in a case where the coloring composition is stored for a long period of time in an environment with variations in temperature, a color filter, a pattern forming method, a solid-state imaging device, and an image display device. The coloring composition includes a heterocycle-containing coloring agent such as a compound represented by Formula (1), a phthalimide compound, a solvent, and a resin. In Formula (1), R 1 to R 13 each independently represent a hydrogen atom or a substituent, and adjacent groups of R 1 to R 8 may be bonded to each other to form a ring, provided that at least one of the pairs of adjacent two groups of R 1 to R 8 is bonded to each other to form an aromatic ring.

First claim

What is claimed is:

1. A coloring composition comprising:
a heterocycle-containing coloring agent including a nitrogen atom;
a phthalimide compound;
a solvent; and
a resin,
wherein the heterocycle-containing coloring agent is at least one selected from Formulae (1) to (4),

in Formula (1), R 1 to R 13 each independently represent a hydrogen atom or a substituent, and adjacent groups of R 1 to R 8 may be bonded to each other to form a ring, provided that, in at least one of pairs of adjacent two groups of R 1 to R 8 , the adjacent two groups of R 1 to R 8 is bonded to each other to form an aromatic ring;
in Formula (2), R 205 and R 208 each independently represent a hydrogen atom, an alkyl group, an aryl group, or a heteroaryl group, R 201 to R 204 , R 206 , and R 207 each independently represent a hydrogen atom or a substituent, Y 1 represents a nitrogen atom or —CR Y1 —, Y 2 represents a sulfur atom or —NR Y2 —, R Y1 and R Y2 each independently represent a hydrogen atom, an alkyl group, an aryl group, or a heteroaryl group, and X represents a bis(sulfonyl)imide anion, a tris(sulfonyl)methide anion, or an anion having a boron atom;
in Formula (3), R 301 , R 311 , and R 310 each independently represent a hydrogen atom, an alkyl group, an aryl group, or a heteroaryl group, and R 302 to R 305 , and R 306 to R 309 each independently represent a hydrogen atom or a substituent, and X represents a bis(sulfonyl)imide anion, a tris(sulfonyl)methide anion, or an anion having a boron atom; and
in Formula (4), R 401 and R 402 each independently represent SO 2 R 403 or COR 403 , and R 403 represents an alkyl group, an aryl group, or a heteroaryl group.

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

in Formula (PI), A 1 to A 4 each independently represent a hydrogen atom, a halogen atom, or an alkyl group.

3. The coloring composition according to claim 2 ,
Wherein, in the phthalimide compound, at least one of A 1 to A 4 in Formula (PI) is a bromine atom.

4. The coloring composition according to claim 1 ,
wherein the phthalimide compound is contained in a proportion of 0.001 to 6.0 parts by mass with respect to 100 parts by mass of the total amount of the compounds represented by Formulae (1) to (4).

5. The coloring composition according to claim 1 , further comprising a curable compound.

6. The coloring composition according to claim 5 , which further comprises a photopolymerization initiator; and
wherein the curable compound includes a radically polymerizable compound.

7. A color filter using the coloring composition according to claim 1 .

8. A solid-state imaging device comprising the color filter according to claim 7 .

9. An image display device comprising the color filter according to claim 7 .

10. A pattern forming method comprising:
forming a coloring composition layer on a support using the coloring composition according to claim 1 ; and
forming a pattern onto the coloring composition layer by a photolithographic method or a dry etching method.
