INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS
An object of the present invention is to provide a laminate with excellent sound insulating properties and bending strength and a laminated glass using the same. In addition, another object of the present invention is to provide a laminate and a laminated glass in which a lowering of sound insulating performance in a high-frequency region to be caused due to a coincidence phenomenon is suppressed, and a time-dependent change of sound insulating performance after preparation of the laminated glass is small, and which are excellent in sound insulating properties over a broad temperature range. The present invention is concerned with a laminate comprising a layer A including a composition containing a resin having a peak at which a tan ´ as measured by conducting a complex shear viscosity test under a condition at a frequency of 1 Hz in accordance with JIS K 7244-10 is maximum, in the range of from -40 to 30°C; and a plurality of layers B, the layer A being laminated between at least two of the layers B, in which a shear storage modulus at a temperature of 25°C as measured by conducting a complex shear viscosity test under a condition at a frequency of 1 Hz in accordance with JIS K 7244-10 is 1.30 MPa or more.
