提供一种隔音性优异的夹层玻璃用中间膜,其隔音性能不仅在吻合效应区提高,而且在质量控制区也提高。一种夹层玻璃用中间膜,其具备隔音层,所述隔音层由包含选自热塑性树脂及热固性树脂中的至少1种树脂(a1)的组合物(A)形成,在频率0.3Hz、拉伸模式下测定将组合物(A)成形为厚度0.8mm而成的片的动态粘弹性时得到的tanδ在温度TA(℃)下具有极大值,温度TA(℃)为‑50~50℃的范围内,在TA(℃)下的tanδ为2.5以上。

    Provided is an interlayer film for laminated glass which is excellent in sound insulation property and has improved sound insulation performance not only in a coincidence region but also in a mass-dominated region. The interlayer film for laminated glass includes a sound insulating layer which is formed from a composition (A) containing at least one resin (a1) selected from a thermoplastic resin and a thermosetting resin, wherein a tan´ obtained when a dynamic viscoelasticity of a sheet, which is obtained by molding the composition (A) to have a thickness of 0.8 mm, is measured at a frequency of 0.3 Hz in a tension mode has a maximal value at a temperature T A (°C), T A (°C) is in a range of -50 to 50°C, and the tan´ at T A (°C) is 2.5 or more.
