Abstract

A coloring composition contains a halogenated zinc phthalocyanine pigment A, an isoindoline pigment B, a resin C, and a curable compound D having an ethylenically unsaturated bonding group, in which the resin C includes a resin C1 having a repeating unit derived from a polymerizable compound Cm having a C Log P value of 3.0 or more with the C Log P value being a calculated value of a Log P which is the common logarithm of a partition coefficient P of 1-octanol/water, and having a cyclic structure in a molecule thereof, and the ratio of the mass of the halogenated zinc phthalocyanine pigment A to the mass of the isoindoline pigment B is 55:45 to 85:15 in terms of the mass of the halogenated zinc phthalocyanine pigment A:the mass of the isoindoline pigment B.

First claim

What is claimed is:

1. A coloring composition comprising:
a halogenated zinc phthalocyanine pigment A;
an isoindoline pigment B;
a resin C; and
a curable compound D,
wherein the resin C includes a resin C1 which does not include an epoxy group, but has a repeating unit formed by polymerizing a polymerizable compound Cm having a C Log P value of 3.0 or more with the C Log P value being a calculated value of a Log P which is the common logarithm of a partition coefficient P of 1-octanol/water, and having a cyclic structure in a molecule thereof,
a ratio of the mass of the halogenated zinc phthalocyanine pigment A to the mass of the isoindoline pigment B is 55:45 to 75:25 in terms of the mass of the halogenated zinc phthalocyanine pigment A:the mass of the isoindoline pigment B, and
the coloring composition includes no coloring agents other than the halogenated zinc phthalocyanine pigment A and the isoindoline pigment B.

2. The coloring composition according to claim 1 ,
wherein the resin C1 is contained in the amount of 5% by mass or more with respect to the total mass of the resin C.

3. The coloring composition according to claim 1 ,
wherein the repeating unit formed by polymerizing the polymerizable compound Cm is contained in the amount of 5% to 95% by mole with respect to all the repeating units of the resin C1.

4. The coloring composition according to claim 1 ,
wherein the resin C1 further has a repeating unit having an acid group.

5. The coloring composition according to claim 1 ,
wherein the polymerizable compound Cm has at least one selected from an aliphatic ring or an aromatic hydrocarbon ring.

6. The coloring composition according to claim 1 ,
wherein an acid value of the resin C1 is 10 to 160 mgKOH/g.

7. The coloring composition according to claim 1 ,
wherein the curable compound D includes a polymerizable compound.

8. The coloring composition according to claim 7 , further comprising a photopolymerization initiator.

9. The coloring composition according to claim 1 ,
wherein the curable compound D includes a compound having an epoxy group.

10. The coloring composition according to claim 1 ,
wherein the ratio of the mass of the halogenated zinc phthalocyanine pigment A to the mass of the isoindoline pigment B is 55:45 to 66:34.

11. The coloring composition according to claim 1 ,
wherein the isoindoline pigment B is C. I. Pigment Yellow 139 or C. I. Pigment Yellow 185.

12. The coloring composition according to claim 1 ,
wherein the isoindoline pigment B is C. I. Pigment Yellow 139.

13. The coloring composition according to claim 1 ,
wherein the C Log P value of the polymerizable compound D1 is 4.0 to 12.0.

14. 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 on the coloring composition layer by a photolithographic method or a dry etching method.

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

16. A solid-state imaging element comprising the color filter according to claim 15 .
