PROBLEM TO BE SOLVED: To provide an intermediate film for a laminated glass which has a multilayer structure, can display an image having high contrast by irradiation with a beam and has excellent heat resistance, and to provide a laminated glass obtained by using the intermediate film for a laminated glass.SOLUTION: There is provided an intermediate film for a laminated glass which comprises a light-emitting layer containing a polyvinyl acetal resin, a plasticizer and a light-emitting material, a first resin layer containing a polyvinyl acetal resin laminated on one surface of the light-emitting layer and a plasticizer, a second resin layer containing a polyvinyl acetal resin laminated on the other surface of the light-emitting layer and a plasticizer, in which the hydroxyl group amount of the polyvinyl acetal resin contained in the light-emitting layer is lower than the hydroxyl group amount of the polyvinyl acetal resin contained in the first resin layer and the hydroxyl group amount of the polyvinyl acetal resin contained in the second resin layer, and the difference between the hydroxyl group amount of the polyvinyl acetal resin contained in the light-emitting layer, and the hydroxyl group amount of the polyvinyl acetal resin contained in the first resin layer and the hydroxyl group amount of the polyvinyl acetal resin contained in the second resin layer is less than 6.5 mol%.SELECTED DRAWING: None |
