Lenses such as optical lenses are pasted and peeled off during processing, but in order to avoid scratches on the lens surface, a protective coating is usually applied to the lens surface. As this protective coating, synthetic resin coatings such as vinyl chloride resin coatings and butyral resin coatings, paraffin wax, etc. are mainly used.

Methylene chloride, trichlorotrifluoroethane, 1, 1
.. 1-) Attempts have been made to use octarogenated hydrocarbons such as lychloroethane, trichlorethylene, and tetrachlorethylene. Among these, methylene chloride in particular has the features of strong dissolving power, low toxicity, non-flammability, and extremely high chemical stability. There is a problem in that it is difficult to achieve easy and complete removal of smearing. In order to solve this problem, various attempts have been made to add certain additives, but no fully satisfactory results have been obtained.

In view of the above-mentioned points, the present inventors have determined that by adding a relatively small amount of other substances to the helogenized hydrocarbon mixture without impeding the performance and features inherent to methylene chloride, it is possible to improve the performance and characteristics of methylene chloride. As a result of extensive research aimed at achieving cleaning effects, it was discovered that the above objectives could be satisfied by adding a hydrophobic surfactant and/or a monocarboxylic acid ester to helogenated hydrocarbons.1 The invention has been completed.

以下本発明の詳細な説明する。The present invention will be explained in detail below.

The blending ratio of the above additives to the helogenated hydrocarbon is:
in the range of 0.01-10% by weight (preferably 0.1-5% by weight) for hydrophobic surfactants, and 1-50% by weight (preferably 10-3011% by weight) for monocarboxylic acid esters. If the amount of these additive components is too small, a sufficient cleaning effect will not be obtained, and on the other hand, even if a large amount exceeding the above range is added, no further effect will be obtained. Not only that, but it is also economically disadvantageous and flammable.
