摘要： An interlayer film for laminated glasses which prevents a decrease in TL value by lessening a coincidence effect and is highly effective in sound insulation in a wide temperature range. The interlayer film comprises: a polyacetal resin blend which comprises a polyacetal resin having an average degree of polymerization of 1,000 to 3,000 and a polyacetal resin having an average degree of polymerization of 3,000 to 5,000 and which has a degree of acetalization of 60 to 85 mol% and an acetyl group content of 8 to 30 mol%; and a plasticizer. The interlayer film, when examined for dynamic viscoelasticity, gives a temperature dependence of loss tangent in which the lowest-temperature side maximum of loss tangent appears at 30°C or lower.
