INTERLAYER FILM FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

An interlayer film for laminated glass is provided with which it is possible to heighten the penetration resistance of laminated glass. In the interlayer film for laminated glass according to the present invention, when the two surfaces of the interlayer film have different glass transition temperatures and the lower glass transition temperature (°C) of the glass transition temperatures of the two surfaces of the interlayer film is expressed by X, or when the two surfaces of the interlayer film have the same glass transition temperature and this glass transition temperature (°C) of the two surfaces of the interlayer film is expressed by X, and when the tensile rupture energy (J/mm2) of the interlayer film is expressed by Y, then X is 20-50°C and Y is 0.043X+0.83 J/mm2 or greater.
