Abstract
A method of covering an abrasion of a glass container comprising coating said container with an aqueous dispersion of a coating material comprising the following components: PA0 (A) liquid paraffin; PA0 (B) at least one fatty acid ester selected from the group consisting of sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, sucrose fatty acid esters, propylene glycol fatty acid esters, glycerin fatty acid esters, and higher alcohol fatty acid esters; and PA0 (C) sodium polyacrylate, the amount of each of said components based on the amount by weight of said dispersion is as follows: PA0 (A) liquid paraffin: 1 to 25 percent; PA0 (B) fatty acid ester: in an amount up to 10 percent; PA0 (C) sodium polyacrylate: in an amount up to 5 percent.
