2. Description of the Related Art A mold is made of two glass plates and a plastic gasket, which is tightened with a fastener to prevent liquid leakage, regulate the sheet thickness, and inject a monomer or syrup such as methyl methacrylate therein. It is common to produce a cast sheet by polymerizing and demolding and releasing. It is known that a glass surface is treated in order to improve the removability from the cast sheet and the glass cell. For example, JP-A-49-128966 proposes a method of treating a glass surface with an organic silane compound having a functional group capable of performing a chemical reaction on the glass surface.

However, although the above-mentioned conventional method for improving the demolding and releasability has a certain effect, it is still insufficient, and the glass surface after the surface treatment becomes cloudy, resulting in a cast sheet. There is a problem such as transfer. In view of such circumstances, the present inventors have conducted intensive studies on a method for producing a cast sheet having excellent demolding and releasability, and as a result, use a glass cell in which a layer made of a specific fluorine-containing silane compound is formed on the inner surface of the cast cell. As a result, it was found that excellent demolding and releasability was obtained without clouding the glass surface, and it was found that it was perpetuated, and the present invention was achieved.
