Abstract
Official abstract text for this publication.
A method of manufacturing a glass resin laminated body includes a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and the resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film. A ratio of an elastic modulus P 1 of a surface layer of the first roller to an elastic modulus P 2 of the resin film P 1 /P 2 satisfies a relation of 3×10 −3 ≤P 1 /P 2 ≤1.0.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a glass resin laminated body comprising: a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film, wherein a thickness of the adhesive layer is less than or equal to 5 μm, a ratio of an elastic modulus P 1 of a surface layer of the first roller to an elastic modulus P 2 of the resin film P 1 /P 2 satisfies a relation of 3×10 −3 ≤P 1 /P 2 ≤1.0, the surface layer of the first roller is formed of a material having an elastic modulus that is lower than the elastic modulus of iron, the surface layer of the first roller is a portion of the first roller 1 mm inward from a surface of the first roller towards a center; and the surface layer of the first roller is formed of a resin from a group consisting of polyethylene terephthalate, polyethylene, or polypropylene. 2. The method of manufacturing a glass resin laminating body according to claim 1 , wherein the resin film includes a polarizing plate disposed on an opposite side of the adhesive layer with respect to the glass film. 3. The method of manufacturing a glass resin laminating body according to claim 2 , wherein the polarizing plate includes a polarizer and a protection film.
