Abstract

This invention has its object to provide an interlayer film for laminated glass an interlayer film for laminated glass which, when assembled into laminated glass, offers good transparency, weathering resistance, adhesion, penetration resistance and other characteristics, does not cause marginal whitening of laminated glass even exposed to a highly humid atmosphere, and free from the risk for a fire hazard in autoclaving or the problem associated with edge trimming and a laminate glass comprising said interlayer film.

This invention is related to an interlayer film for laminated glass comprising a plasticized poly(vinyl acetal) resin film, wherein, when a laminated glass fabricated by interposing said interlayer film between a pair of glass sheets each 2.0 to 4.0 mm thick is allowed to sit in an environment of 80 °C
and 95% relative humidity for 2 weeks, the distance of whitening from its edge is not greater than 7 mm, and when said interlayer film for laminated glass is allowed to sit at 150 °C for 1 hour, its weight loss is not greater than 3 weight %.
