Abstract:
There is provided an interlayer film for laminated glass with which a low yellow index value, low excitation purity and high heat shielding properties can be achieved in spite of the thickness varying with places. The interlayer film for laminated glass according to the present invention has a two or more-layer structure, has a thickness of one end thinner than a thickness of the other end at the opposite side of the one end and includes a first layer containing a thermoplastic resin and a second layer containing a thermoplastic resin, the difference between the maximum thickness and the minimum thickness in the first layer is smaller than the difference between the maximum thickness and the minimum thickness in the second layer, and the first layer contains a heat shielding compound.
