Abstract

The invention relates to primer coating compositions exhibiting very good adhesion properties on a large variety of substrates, in particular plastic substrates such as ophthalmic lenses made of organic glasses and which also impart good impact resistance properties to the thus coated substrates. The invention also concerns substrates coated with these primer coating compositions as well as a method for making such coated substrates.
