Temporary Protection Of Glass

#TemporaryProtectionOfGlass

One subject of the invention is a glass substrate coated with a continuous temporary protection film, said film essentially consisting of a stack of discernible colloidal polymer particles. Another

subject of the invention is a process for coating a glass substrate with a continuous temporary protection film, in which process an aqueous dispersion of colloidal particles of at least one water-insoluble

solid polymer is deposited on at least one surface of said substrate and then the film thus obtained is dried at a temperature above the glass transition temperature of said at least one polymer but not exceeding 50°C.
