1. A laminate comprising:
a wavelength selective absorption layer containing a thermoplastic polymer resin, a dye including at least one of the following dyes A to D, and an antifading agent for a dye; and
a gas barrier layer directly arranged on at least one surface of the wavelength selective absorption layer,
wherein the gas barrier layer contains a crystalline resin,
a thickness of the gas barrier layer is 0.1 μm to 10 μm, and
an oxygen permeability of the gas barrier layer is 60 cc/m2·day·atm or less,
dye A: a dye having a main absorption wavelength range at a wavelength of 390 to 435 nm,
dye B: a dye having a main absorption wavelength range at a wavelength of 480 to 520 nm,
dye C: a dye having a main absorption wavelength range at a wavelength of 580 to 620 nm, and
dye D: a dye having a main absorption wavelength range at a wavelength of 680 to 780 nm, and wherein the amount of the thermoplastic polymer resin in the wavelength selective absorption layer is 70% by mass or more and 99.90% by mass or less.
