PROCESS FOR PRODUCING A CURVED SUBSTRATE COVERED WITH A FILM |
摘要 |
A process for producing a curved substrate (20) covered with a film (10) comprises a heat treatment of the film performed between a step of preforming said film and a step of assembling the film with the substrate. A maximum temperature of the pre-assembling heat treatment is higher than another maximum temperature of a post-assembling heat treatment (F) which is performed after the assembling step. Then the assembly of the substrate (20) with the film (10) is not altered during said post-assembling heat treatment. In particular, no defect and no delamination appear, and no change in the curved shape of the substrate is caused by the post-assembling heat treatment, even if the substrate (20) has a low glass transition temperature.
