Multilayer film, interlayer film comprising the multilayer film and laminated glass and sound-insulating glass laminate comprising the interlayer film
The present invention relates to a multilayer film. In various embodiments the multilayer film is an interlayer film for laminated glass. The present invention also relates to an interlayer film for laminated glass, wherein the laminated glass has excellent sound insulating properties. The present invention also relates to a laminated glass that is obtained using this interlayer film. The present invention can effectively improve the compatibility of the resin film (B) with the plasticizer so that the intermediate layer (i.e., the resin film (B)) allows to add more plasticizer(s) to achieve the effect of enhancing sound-insulating. Furthermore, the intermediate layer of the multilayer film uses different plasticizer from the non-intermediate layer of the multilayer film so as to prevent the migration of plasticizers between different layers and the multilayer film has little or no plasticizer bleed-out.
