Abstract
The present invention relates to an aqueous-based coating composition for forming strippable, protective coating for protecting surfaces, such as glass, metal, ceramic, plastic or other materials of construction. More specifically, the compositions and coatings formed therefrom of this invention are particularly useful in connection with protecting precision surfaces, such as optical lenses, including but not limited to ophthalmic lenses, telescopic lenses, microscopic lenses, and the like, which protection is desirably only of a temporary nature.
