Document Type and Number:
WIPO Patent Application WO/2018/061910
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a molded body that has superior transparency, processability, and formability while still suppressing the occurrence of coloring. A method for manufacturing a molded body (10) has a film-material forming step (33) and a molding step (32). In the film-material forming step (33), an elongated film material is formed from cellulose acylate. In the molding step (32), the obtained film material (20) and a substrate material (22) formed of a thermoplastic resin are integrally molded thereby forming the molded body (10) having a cellulose acylate film (13) and a transparent substrate (11) by thermoforming at a forming temperature in the range of 150-240°C inclusive.
