    Abstract: The optical article e.g. ophthalmic lens comprises an external water- and/or oil-repellent coating on one of its principle surfaces and a strippable coating directly deposited on the external water- and/or oil repellent coating. The external water- and/or oil repellent coating has a surface energy = 12 mJ/m 2>. The strippable coating has a surface energy >= 30 mJ/m 2>, and has a polar surface energy lower than 26 mJ/m 2>. A thickness and an elongation-to-break of the strippable coating is 15-20 mu m and = 150% respectively.

A thickness and an elongation-to-break of the strippable coating is 15-20 mu m and = 150% respectively. A solid content of polyurethane latex is 25-45 wt.% with respect to a total weight of the latex composition. The external water- and/or oil-repellent coating is deposited on a mono or multi-layer anti-reflection coating.
