| titleOfInvention | Process for the production of thin films of cellulose derivative |
| abstract | The manufacture of very thin films of cellulose derivatives, particularly cellulose esters and ethers, described in the parent Specification, is modified by employing a base which is soluble or slightly soluble in the solvent used in the preparation of the soution of the cellulose derivative from which the film is made, and the film is removed from the base before the solvent has completely evaporated, that is, as soon as possible after solidification, or alternatively, the cellulose derivative is applied to the base in the form of a highly-concentrated viscous or pasty solution. Suitable bases are cellulose acetate and other cellulose derivatives, indiarubber, a rubberized fabric, gelatine, &c.; and to the base or to the solution may be added substances such as glycerine, a glycerine derivative or a mineral oil, which serve to decrease the adhesiveness of the film to the base. Layers of solutions of different cellulose derivatives may be spread one on the other; after drying, the layers can be separated. According as the base has a smooth or patterned or ornamental surface so the film will be plain or ornamented. |
