Aqueous dispersions comprising modified polyethylene with an average molecular weight of 500 to 10,000 are disclosed. The polyethylene has one or more laterally bound group(s) of the formula -CONH(CH2)nNR1R2 wherein R1 and R2 are the same or different and represent a low molecular weight alkyl group with 1 to 4 carbon atoms and n is 2 or 3, or its salts with aliphatic carboxylic acids with 1 to 3 carbon atoms. The aqueous dispersion is applied to glass surfaces, especially the external surfaces of glass containers. The dispersions are suitable especially for socalled cold-end finishing. The protective layers obtained have very good smoothing values. The protective layers are resistant to the repeated action of hot, aqueous washing liquors and retain their smoothness. Glass containers, provided with the protective layer, can be labelled in the usual manner. |
