Abstract:
A pressure-sensitive adhesive containing a near infrared absorbing dye having excellent shielding function for near infrared rays and excellent in durability is provided. In a light resistance test, a layer of the pressure-sensitive adhesive having a thickness of 25±5 μm has an absorption intensity at the maximum absorption wavelength of the near infrared absorbing dye after a light resistance test of 50% or more of the absorption intensity before the test in which light with an irradiance of 64.5 W/m2 at a wavelength of 300 to 400 nm is irradiated on the layer for 160 hours.
