Abstract:
1. A process for preparing an optical article, comprising: (a) providing an optical article comprising a substrate having an exposed surface, (b) depositing onto said exposed surface of the substrate a first layer of a first curable composition comprising at least one cleavable surfactant, wherein the cleavable surfactant is selected from the group consisting of: (c) curing at least partially said first curable composition, thereby forming a first coating, (d) forming a second coating onto said first coating, and (e) obtaining an optical article comprising a substrate successively coated with said first coating and said second coating, said first coating adhering to said second coating, wherein, after said first curable composition has been deposited onto the exposed surface of the substrate, and before step (d), said optical article is subjected to a treatment step resulting in a cleavage of at least a portion of the cleavable surfactant, and wherein no surface treatment with energetic species selected from ions, radicals, photons or electrons is performed on the first coating before proceeding to step (d).
