This invention relates to a method for pulverizing gelatin and to products in which pulverized gelatin is used. The present invention relates to a method for pulverizing hydrophilic and water-soluble dry gelatin with relatively high jelly strength using as a medium hydrophilic organic solvent dimethylformamide or organic solvent admixed with dimethylformamide in an atmosphere where moisture is shut out. It further relates to paints containing synthetic resin solutions in dimethylformamide or the organic solvent admixed with dimethylformamide which contains gelatin particles pulverized into 30 microns or smaller in size by the invention method. It provides paint layers, coating layers, films and finished cloths that are formed by using said paints and synthetic resin solutions. By eluting gelatin particles with hot water, paint layers, coating layers, film and finished cloths with excellent moisture permeability can be obtained. |
