Abstract

A composition includes: a compound represented by Formula (1); and at least one selected from the group consisting of a curable compound and a resin. Provided are a film that is formed using the composition, an infrared cut filter, a solid image pickup element, an infrared sensor, and a camera module. Further, provided is a compound represented by Formula (1). R 1 and R 2 each independently represent a group represented by the following Formula (2) and having a SP value of 12.2 (cal/cm 3 ) 1/2 or higher as a whole.

First claim

What is claimed is:

*—X 1 -L 1 -Y 1   (2)

in Formula (2), X 1 represents a m-phenylene group, a p-phenylene group, a divalent fused polycyclic aromatic ring group in which two or more aromatic rings are fused, or a divalent heteroaromatic ring group, L 1 represents a single bond or a divalent linking group, Y 1 represents a polar group, and * represents a linking site to a pyrrolopyrrole ring in Formula (1).

2. The composition according to claim 1 ,
wherein Y 1 represents a group having at least one structure selected from the group consisting of an N-substituted imide structure, an acid anhydride structure, a cyano group, an alkylsulfone group, an arylsulfone group, an alkylsulfoxide group, an arylsulfoxide group, an N-disubstituted sulfonamide group, and an N-disubstituted amide group.

3. The composition according to claim 1 , further comprising:
a colorant derivative other than the compound represented by Formula (1).

4. The composition according to claim 1 ,
wherein a viscosity at 25° C. is 1 mPa·s to 100 mPa·s.

5. The composition according to claim 1 ,
wherein the compound represented by Formula (1) is in the form of particles.

6. The composition according to claim 5 ,
wherein a volume average particle size of the compound represented by Formula (1) is 5 nm to 500 nm.

7. The composition according to claim 1 , comprising:
a resin having a polyester chain as the resin.

8. The composition according to claim 1 , comprising:
an alkali-soluble resin as the resin.

9. The composition according to claim 1 , comprising:
the curable compound.

10. The composition according to claim 9 , further comprising:
a polymerization initiator.

11. A film which is formed using the composition according to claim 1 .

12. A film that is formed by curing the composition according to claim 9 .

13. An infrared cut filter comprising:
the film according to claim 11 .

14. A solid image pickup element comprising:
the film according to claim 11 .

15. An infrared sensor comprising:
the film according to claim 11 .

16. A camera module comprising:
a solid image pickup element; and
the infrared cut filter according to claim 13 .

17. A compound represented by the following Formula (1),

wherein, in Formula (1), R 1 and R 2 each independently represent a group represented by the following Formula (2) and having a solubility parameter of 12.2 (cal/cm 3 ) 1/2 or higher as a whole, R 3 to R 6 each independently represent a cyano group, an acyl group, an alkoxycarbonyl group, an alkyl group, an arylsulfinyl group, or a heteroaryl group, R 7 and R 8 each independently represent a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, —BR 9 R 10 , or a metal atom, at least one of R 7 or R 8 and at least one of R 1 to R 4 may form a covalent bond or a coordinate bond, R 9 and R 10 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, or a heteroaryloxy group, and R 9 and R 10 may be bonded to each other to form a ring, and
*—X 1 -L 1 -Y 1   (2)

in Formula (2), X 1 represents a m-phenylene group, a p-phenylene group, a divalent fused polycyclic aromatic ring group in which two or more aromatic rings are fused, or a divalent heteroaromatic ring group, L 1 represents a single bond or a divalent linking group, Y 1 represents a polar group, and * represents a linking site to a pyrrolopyrrole ring in Formula (1).
