Abstract:
An interlayer film for laminated glass that suppresses the transmittance of ultraviolet rays with a wave length of 400 nm to 1% or less, and has high light resistance. The interlayer film for laminated glass comprises a thermoplastic resin, an ultraviolet absorber having a structure of formula (1), and an ultraviolet absorber having a structure of formula (2), wherein the amount of the ultraviolet absorber of formula (1) is 0.001 to 0.05% by weight, and the amount of the ultraviolet absorber of formula (2) is 0.5 to 1.0% by weight; wherein R1 is a C1-3 alkyl group; R2 is hydrogen, a C1-10 alkyl group, or a C7-10 aralkyl group; R3 is hydrogen or a C1-8 alkyl group; and R4 is hydrogen or a C1-8 alkyl group.
