Abstract: Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property of laminated glass in a relatively low temperature region. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure, and when the interlayer film is sandwiched between two sheets of green glass having a thickness of 2 mm to obtain a laminated glass X with a size of 25 mm long×300 mm wide, an absolute value of difference between a secondary resonance frequency of the laminated glass X before irradiation with xenon light and a secondary resonance frequency of the laminated glass X after irradiation with xenon light determined by a specific xenon light irradiation test is 60 Hz or more, a loss factor at 20° C. of the laminated glass X is 0.25 or more, and a solar transmittance of the laminated glass X is 50% or less.

Abstract: Provided is an interlayer film for laminated glass capable of being enhanced in sound insulating properties of laminated glass at 30° C. The interlayer film for laminated glass according to the present invention includes first and second layers each containing a thermoplastic resin and a plasticizer, and when an absolute value of a difference in cloud point using the thermoplastic resin and the plasticizer in each of the first and second layers is represented by Xa, and a content based on parts by weight of the entire plasticizer in the interlayer film for laminated glass relative to 100 parts by weight of the entire thermoplastic resin in the interlayer film for laminated glass is represented by Z, the interlayer film satisfies at least one of the first constitution: “Xa≤115 and Z≤−0.16Xa+59” and the second constitution: “the thermoplastic resin in the first layer is a polyvinyl acetal resin, and when the acetylation degree on a mole percent basis of the polyvinyl acetal resin in the first layer is represented by Y, Y≥2 and Z≤−0.16Xa−0.2Y+59”.

Abstract: Provided is an interlayer film for laminated glass capable of suppressing the change in sound insulating property of laminated glass in a relatively high temperature region. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure, and when the interlayer film is sandwiched between two sheets of green glass having a thickness of 2 mm to obtain a laminated glass X with a size of 25 mm long x 300 mm wide, an absolute value of difference between a secondary resonance frequency of the laminated glass X before irradiation with xenon light and a secondary resonance frequency of the laminated glass X after irradiation with xenon light determined by a specific xenon light irradiation test is 70 Hz or less, a loss factor at 20° C. of the laminated glass X is 0.24 or more, and a solar transmittance of the laminated glass X is 50 or less.

Abstract: Provided is an interlayer film for laminated glass capable of suppressing the generation of an optical strain in laminated glass, and enhancing the damping performance of laminated glass. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer or two or more-layer structure, and includes a first layer containing a resin, and when the interlayer film is arranged between two sheets of clear float glass having a thickness of 2.5 mm to obtain a laminated glass X with a size of 150 mm in length and 300 mm in width, and the obtained laminated glass X is subjected to a specific measurement of optical strain, an optical strain value is 3.00 or less, whereas when the interlayer film is arranged between two sheets of clear float glass having a thickness of 2.1 mm to obtain a laminated glass Y having a size of 950 mm in length and 1500 mm in width, and the obtained laminated glass Y is subjected to a specific measurement of damping ratio, a damping ratio at a resonance frequency of 50 Hz or more and 80 Hz or less is 5.0% or more.
