Abstract
An interlayer film for a laminated glass according to the present invention comprises a benzotriazole-based compound having a maximum absorption wavelength peak of 370 nm or more and 405 nm or less, and has a transmittance difference represented by T1000−T0 of less than 2.0%, wherein T1000 represents a transmittance at 400 nm after being irradiated with xenon light having an irradiance of 180 w/m2 for 1000 hours at a black panel temperature of 83° C., a temperature in a chamber of 50° C., and a humidity in a chamber of 50% RH, and T0 represents a transmittance at 400 nm before being irradiated.
