Abstract

A composition includes a near-infrared absorber, a color material that transmits near-infrared rays and shields visible light, at least one compound selected from the group consisting of a resin having a glass transition temperature of 100° C. or higher, and a resin precursor of the resin having a glass transition temperature of 100° C. or higher, and a surfactant.

First claim

What is claimed is:

1. A composition comprising:
a near-infrared absorber;
a color material that transmits near-infrared rays and shields visible light;
at least one compound selected from the group consisting of a resin having a glass transition temperature of 100° C. or higher, and a resin precursor of the resin having a glass transition temperature of 100° C. or higher; and
a surfactant,
wherein the resin having a glass transition temperature of 100° C. or higher is a cyclic olefin resin.

2. The composition according to claim 1 ,
wherein the color material that transmits near-infrared rays and shields visible light includes an organic black coloring agent.

3. The composition according to claim 2 ,
wherein the organic black coloring agent includes at least one selected from a compound having a perylene skeleton or a compound having a lactam skeleton.

4. The composition according to claim 1 ,
wherein the near-infrared absorber is a compound having a maximum absorption wavelength in the wavelength range of 700 to 1,800 nm.

5. The composition according to claim 1 ,
wherein the near-infrared absorber includes at least one selected from a colorant compound having a cation and an anion in the same molecule, a colorant compound which is a salt of a cationic chromophore and a counter anion, or a colorant compound which is a salt of an anionic chromophore and a counter cation.

6. The composition according to claim 1 ,
wherein the near-infrared absorber includes at least one selected from a squarylium compound or a croconium compound.

7. The composition according to claim 1 ,
wherein the surfactant is a fluorine-based surfactant.

8. The composition according to claim 1 ,
wherein the composition is a composition for a near-infrared transmitting filter.

9. A film obtained by using the composition according to claim 1 .

10. A dry film obtained by using the composition according to claim 1 .

11. A pattern forming method comprising:
applying the composition according to claim 1 onto a support to form a composition layer; and
subjecting the composition layer to a photolithography method or a dry etching method to form a pattern.

12. A pattern forming method comprising:
applying the dry film according to claim 10 onto a support to form a dry film layer; and
subjecting the dry film layer to a photolithography method or a dry etching method to form a pattern.

13. A near-infrared transmitting filter obtained by using the composition according to claim 1 .

14. A structure comprising:
a light-receiving element;
first pixels constituted of a laminate including a color filter and a near-infrared cut filter, provided on a light-receiving surface of the light-receiving element; and
second pixels including the near-infrared transmitting filter according to claim 13 , provided at a position different from a region where the first pixels are provided, on the light-receiving surface of the light-receiving element.

15. An optical sensor comprising the near-infrared transmitting filter according to claim 13 .

16. An image display device comprising the near-infrared transmitting filter according to claim 13 .
