Abstract
A formed body includes a base material, an adhesive layer, and a cellulose acylate film. The base material is formed of a thermoplastic resin and is in the form of a transparent sheet. The adhesive layer bonds the base material and the cellulose acylate film. The cellulose acylate film has a thickness in a range of 15 μm or more and 100 μm or less, and is formed of cellulose acylate including an ester oligomer or a sugar ester derivative.
Claims6
A formed body comprising:
- a transparent base material that is formed of a thermoplastic resin;
- an adhesive layer that is provided on a surface of the base material;
- and
- a film that is provided on a surface of the adhesive layer opposite to the base material, has a thickness in a range of 15 μm or more and 100 μm or less, and is formed of cellulose acylate including an ester oligomer having a molecular weight in a range of 700 or more and 5000 or less,
- wherein the film has
- a cellulose acylate layer that is provided on a side close to the adhesive layer and is formed of the cellulose acylate, and
- a saponified layer that is provided on a side opposite to the adhesive layer and contains the cellulose acylate which is saponified,
- in a case where an amount of acyl groups in the saponified layer is X and an amount of acyl groups in the cellulose acylate layer is Y, an acyl group ratio determined by X/Y is at most 0.7, and
- wherein, in a surface of the saponified layer, a contact angle of pure water 15 seconds after the pure water is dropped is 35 degrees or less.
