Abstract

A laminate includes: a near infrared light absorbing layer that includes a near infrared absorbing colorant; and a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant, in which in at least one of the near infrared light absorbing layer or the color filter layer, a content of a compound in which an acid group selected from a sulfo group, a phosphate group, or a carboxyl group is bonded to a colorant skeleton is 0.1 to 99.9 mass % with respect to a total mass of compounds having a colorant skeleton.

First claim

What is claimed is:

1 . A laminate comprising:
a near infrared light absorbing layer that includes a near infrared absorbing colorant; and a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant, wherein in at least one of the near infrared light absorbing layer or the color filter layer, a content of a compound in which an acid group selected from the group consisting of a sulfo group, a phosphate group, and a carboxyl group is bonded to a colorant skeleton is 0.1 to 99.9 mass % with respect to a total mass of compounds having a colorant skeleton.

2 . The laminate according to claim 1 ,
wherein the color filter layer includes colored pixels of multiple colors, and in each of the colored pixels, a content of the compound to which the acid group is bonded is 0.1 to 99.9 mass % with respect to the total mass of the compounds having a colorant skeleton.

3 . The laminate according to claim 1 ,
wherein in the near infrared light absorbing layer and the color filter layer, a content of the compound to which the acid group is bonded is 0.1 to 99.9 mass % with respect to the total mass of the compounds having a colorant skeleton.

4 . The laminate according to claim 1 ,
wherein the near infrared absorbing colorant is at least one selected from the group consisting of a pyrrolopyrrole compound, a cyanine compound, and a squarylium compound.

5 . The laminate according to claim 1 , further comprising:
an oxygen barrier film.

6 . The laminate according to claim 4 , further comprising:
an oxygen barrier film.

7 . The laminate according to claim 1 , further comprising:
an oxygen barrier film that is formed on a laminate including the near infrared light absorbing layer and the color filter layer.

8 . The laminate according to claim 4 , further comprising:
an oxygen barrier film that is formed on a laminate including the near infrared light absorbing layer and the color filter layer.

9 . The laminate according to claim 5 ,
wherein an oxygen permeability of the oxygen barrier film is 200 ml/m 2 ⋅day⋅atm or lower.

10 . The laminate according to claim 7 ,
wherein an oxygen permeability of the oxygen barrier film is 200 ml/m 2 ⋅day⋅atm or lower.

11 . An optical filter comprising:
the laminate according to claim 1 .

12 . A solid image pickup element comprising:
the laminate according to claim 1 .

13 . An image display device comprising:
the laminate according to claim 1 .

14 . An infrared sensor comprising:
the laminate according to claim 1 .

15 . A kit that is used for manufacturing a laminate,
the laminate including: a near infrared light absorbing layer that includes a near infrared absorbing colorant, and a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant, in which in at least one of the near infrared light absorbing layer or the color filter layer, a content of a compound in which an acid group selected from the group consisting of a sulfo group, a phosphate group, and a carboxyl group is bonded to a colorant skeleton is 0.1 to 99.9 mass % with respect to a total mass of compounds having a colorant skeleton, and the kit comprising:
a near infrared light absorbing layer-forming composition that includes a near infrared absorbing colorant; and
a color filter layer-forming composition that includes a chromatic colorant,
wherein in at least one of the near infrared light absorbing layer-forming composition or the color filter layer-forming composition, a content of a compound in which an acid group selected from the group consisting of a sulfo group, a phosphate group, and a carboxyl group is bonded to a colorant skeleton is 0.1 to 99.9 mass % with respect to a total mass of compounds having a colorant skeleton.
