PURPOSE:To provide a coating compsn. which is excellent in hiding effect and water resistance and can be completely peeled off during the washing of a bottle, by blending liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester and glycerol fatty acid ester. CONSTITUTION:Liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester and glycerol fatty acid ester are blended together. If necessary, an appropriate quantity of water is further added thereto. Any of the above three fatty acid esters has an emulsifying action. Liquid paraffin is effective in spreading over the surface of a bottle and increasing an action of penetrating into scratched regions. These fatty acid esters are used in such a proportion that they account for 25-5% of the total quantity of the compsn. The glycerol fatty acid esters include those derived form 10-21 C fatty acids, among which lauric acid, palmitic acid, stearic acid and oleic acid are preferred.
