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;
a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant; and
an oxygen barrier film that is formed on a laminate including the near infrared light absorbing layer and the color filter layer in this order,
wherein the near infrared absorbing colorant is a dye,
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,
the color filter layer includes a pigment as the chromatic colorant,
5 to 50 mass % of the chromatic colorant has a sulfo group bonded to a colorant skeleton,
the color filter layer includes colored pixels of multiple colors, and each of the colored pixels does not include the chromatic colorant in which an amino group is bonded to a colorant skeleton of the chromatic colorant or a colorant derivative in which an amino group is bonded to a colorant skeleton of the colorant derivative,
an oxygen permeability of the oxygen barrier film is 200 ml/m 2 ·day·atm or lower,
the oxygen barrier film is formed at least one selected form the group consisting of SiO 2 , SiN, Al 2 O 3 , CaO, Fe 2 O 3 , MgO, GazO, ZrO 2 , TiO 2 , CaF 2 , tetraethoxysilane, tetraethyl orthotitanate, tetramethoxysilane, ethyltriethoxysilane, and methyl trimethoxysilane, and
the oxygen barrier film is an outmost layer interposed with a planarizing layer and a lens layer.

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

3. A solid image pickup element comprising:
a sensor and
the laminate according to claim 1 .

4. An image display device comprising:
an image display device and
the laminate according to claim 1 .

5. An infrared sensor comprising:
a sensor and
the laminate according to claim 1 .

6. The laminate according to claim 1 ,
wherein the oxygen barrier film is formed using SiO 2 .

7. 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,
a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant, and
an oxygen barrier film that is formed on a laminate including the near infrared light absorbing layer and the color filter layer in this order, in which 5 to 50 mass % of at least one of the near infrared light absorbing colorant and the chromatic colorant has an acid group selected from the group consisting of a sulfo group, a phosphate group, and a carboxyl group bonded to a colorant skeleton, and
the kit comprising:
a near infrared light absorbing layer-forming composition that includes the near infrared absorbing colorant; and
a color filter layer-forming composition that includes the chromatic colorant,
wherein the near infrared absorbing colorant is a dye,
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 to 50 mass % of the chromatic colorant has a sulfo group bonded to the colorant skeleton, and
the color filter layer includes colored pixels of multiple colors, and each of the colored pixels does not include the chromatic colorant in which an amino group is bonded to a colorant skeleton of the chromatic colorant or a colorant derivative in which an amino group is bonded to a colorant skeleton of the colorant derivative,
an oxygen permeability of the oxygen barrier film is 200 ml/m 2 ·day·atm or lower,
the oxygen barrier film is formed at least one selected form the group consisting of SiO 2 , SiN, Al 2 O 3 , CaO, Fe 2 O 3 , MgO, GazO, ZrO 2 , TiO 2 , CaF 2 , tetraethoxysilane, tetraethyl orthotitanate, tetramethoxysilane, ethyltriethoxysilane, and methyl trimethoxysilane, and
the oxygen barrier film is an outmost layer interposed with a planarizing layer and a lens layer.

8. The laminate according to claim 7 ,
wherein the oxygen barrier film is formed using SiO 2 .
