Use of a laminated glass comprising an interlayer film

摘要

The invention provides an interlayer film for a laminated glass and a laminated glass,
which are protected against a slump in TL value through attenuation of said coincidence effect and adapted to display an outstanding sound insulation performance over a broad temperature range. An interlayer film for a laminated glass
which shows a temperature dependence of loss tangent
in which the lowest-temperature side maximum of loss tangent appears at 30°C or lower when examined for dynamic viscoelasticity.
