<p>An intermediate film for a laminated glass comprising a plasticized poly(vinyl acetal) resin film, which exhibits a whitening length from an edge of 7 mm or less wherein the whitening length is measured after allowing a laminated glass, which has been manufactured by sandwiching the above intermediate film between two sheets of glass having a thickness of 2.0 to 4.0 mm, to stand for two weeks under an environment of 80 °C and a relative humidity of 95 %, and exhibits a weight decrease during being left to stand at 150 °C for one hour of 3 wt% or less; and a laminated glass using the same. This laminated glass not only is excellent in characteristics such as transparency, weather resistance, adhesiveness and resistance to cutting through, but also exhibits reduced whitening of a marginal part thereof even when it is left in an atmosphere of a high humidity, and further is free from problems relating to firing during autoclaving and to edge cut for trimming.</p> |
