ABSTRACT:
A method for preparing a decomposable film which comprises the steps of dispersing poly-.alpha.-methylstyrene or a polyalkylene carbonate in water, or preferably dissolving poly-.alpha.-methylstyrene or the polyalkylene carbonate in a solvent, dispersing the resulting solution in water, vaporizing the solvent so that the content of the solvent may be in the range of from 20 to 100% by weight based on the weight of poly-.alpha.-methylstyrene or the polyalkylene carbonate, applying the resulting aqueous emulsion, and then drying the same; and a method for preparing a metal film having a flat surface which comprises the steps of depositing a metal on the surface of the decomposable film, and then treating the film at a temperature higher than the decomposition temperature of the film.
