Provided is an intermediate film for laminated glass, which is capable of achieving a low yellow index value, a low excitation purity, and a high heat insulation property regardless of the thickness varies depending on the position. This interlayer for laminated glass has a structure of two or more layers, has a thickness at one end that is thinner than a thickness at the other end on the opposite side from the one end, and is provided with 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 of the first layer is smaller than the difference between the maximum thickness and the minimum thickness of the second layer, and the first layer contains a heat-insulating compound.
本发明提供一种夹层玻璃用中间膜,不管厚度根据位置不同而各异,均可以达成较低的黄色指数值、较低的激发纯度和较高的隔热性。本发明的夹层玻璃用中间膜具有2层以上的结构,一端的厚度比上述一端的相反侧的另一端的厚度薄,具备包含热塑性树脂的第一层和包含热塑性树脂的第二层,上述第一层的最大厚度和最小厚度之差比上述第二层的最大厚度和最小厚度之差小,上述第一层包含隔热性化合物。
