    摘要： The present invention provides an intermediate film for laminated glass which can improve the sound-insulating property. The intermediate film for laminated glass according to the present invention has a layered structure including at least two layers, comprising: a first layer containing a polyvinyl acetal resin and a plasticizer; and a second layer positioned on a first surface of the first layer. In a phase diagram of three values including a degree of acetalization, a degree of acetylation, and a hydroxy group content of the polyvinyl acetal resin contained in the first layer, the values of the degree of acetalization, the degree of acetylation, and the hydroxy group content each fall within a region surrounded by a line including four straight lines connecting a first coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 70 mol%: 30 mol%: 0 mol%), a second coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 34 mol%:30 mol%:36 mol%), a third coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 94 mol%: 0 mol%:6 mol%), and a fourth coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 100 mol%: 0 mol%: 0 mol%) in the stated order.

    摘要： The present invention aims to provide an intermediate film for laminated glass which, in the case of being used for constituting a laminated glass, enables to improve the sound-insulating property in a high frequency range of the obtained laminated glass over a wide range of temperature. The intermediate film for laminated glass of the present invention1 has a structure that a first layer 2, a second layer 3, and a third layer 4 are laminated in this order, each of the first, second, and third layers 2, 3, and 4 contains a polyvinyl acetal resin and a plasticizer, the hydroxy group content in the polyvinyl acetal resin contained in the first layer 2 is lower than each of the hydroxy group contents in the polyvinyl acetal resins contained in the second and third layers 3 and 4, and the ratio (T1/(T2+T3)) of the thickness (T1) of the first layer 2 to the total thickness (T2+T3) of the second and third layers 3 and 4 is 0.14 or lower.
