Abstract of the Disclosure Modified polyethylene with an average molecular weight of 500 to 10,000is 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 molecu- lar 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 modified polyethylene is applied in the form of an aqueous dispersion, to glass surfaces, especially the external surfaces of glass containers. The modified polyethylene is suitable especially for so-called 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 con- tainers, provided with the protective layer, can be labelled in the usual manner.
