PRESSURE-SENSITIVE ADHESIVE CONTAINING NEAR INFRARED ABSORBING COLORING MATTER

摘要

A pressure-sensitive adhesive containing a near infrared absorbing dye having excellent shielding function for near infrared rays and excellent in durability is provided. A pressure-sensitive adhesive containing a near infrared absorbing dye, wherein the layer of the pressure-sensitive adhesive has a thickness of 25 ± 5 µm and absorption intensity at the maximum absorption wavelength of the near infrared absorbing dye after light resistance test is 50% or more for absorption intensity before the test in the light resistance test in which light with an irradiance of 64.5 W/m 2 at a wavelength of 300 to 400 nm is irradiated for the layer for 160 hours.
