Document Type and Number:
WIPO Patent Application WO/2023/042661
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a laminated film that has further uniform properties regarding optical characteristics and the like, and that can maintain said properties for a further extended period of time. This laminated film is characterized by comprising two or more different types of thermoplastic resin layers and is characterized in that, when ratios of interface layer thicknesses analyzed through GCIB-TOF-SIMS with respect to the film thickness are calculated in all types of interfaces formed by the different thermoplastic resin layers, the lowest value thereof is 1.0×10-4-1.0×10-2.
