Abstract:
The present invention aims to provide an intermediate film for laminated glass which, in the case of being used for constituting a laminated glass, enables to improve the sound-insulating property of the obtained laminated glass, and a laminated glass. The intermediate film 1 for laminated glass of the present invention comprises a first layer 2 which contains a polyvinyl acetal resin and a plasticizer, and the polyvinyl acetal resin and the first plasticizer are a polyvinyl acetal resin and a first plasticizer which have a cloud point of 5° C. or lower when the cloud point is measured using a solution prepared by dissolving 8 parts by weight of the polyvinyl acetal resin in 100 parts by weight of the first plasticizer; and the laminated glass 11 of the present invention comprises first and second components for laminated glass, and the intermediate film 1 for laminated glass sandwiched between the first and second components for laminated glass.
