Description of the Related Art Conventionally, as a material for a container, for example, Japanese Patent Laid-Open No. 1-264040 describes a laminated material composed of a base material such as paper and a resin layer laminated on the base material. .. Since this laminated material has been devised in the resin layer, it is excellent in the effect of suppressing the foaming of carbonated beverages and also in the stacking characteristics of a bending machine, but it does not always have sufficient moldability, and it is particularly difficult to use paper-based materials. When a material is used, there is a problem that it cannot be formed into a cup at once by vacuum forming or pressure forming.

られる。As the silicone compound in the present invention, an organosilicon compound having at least one hydrogen group is reacted with a hydrocarbon compound having at least one double bond capable of reacting with the hydrogen group and having 18 or more carbon atoms. Comb-type graft polymers obtained from the above are particularly preferably used. A method for producing this modified silicone compound is described in, for example, JP-A-63-
It is described in detail in Japanese Patent No. 3076. As the silicone compound, general silicone oil, modified silicone oil partially modified with methylstyrene group, methylphenyl group, etc., and silicone polymer are generally used (GP).
