Abstract
The present invention is dedicated to a process for improving the adhesion properties between a first coating obtained from a curable composition and a second coating, through the incorporation of a cleavable surfactant in said curable composition and subsequent cleavage thereof. Said process comprises: depositing onto the substrate of an optical article a first layer of a first curable composition comprising at least one cleavable surfactant, curing at least partially said first curable composition, thereby forming a first coating, forming a second coating onto said first coating, wherein, after said first curable composition has been deposited onto the substrate, and before deposition of the second coating, said optical article is subjected to a treatment step resulting in a cleavage of at least a portion of the cleavable surfactant. Curable compositions containing cleavable surfactants and optical articles having deposited thereon stacks of coatings formed by the above process are also described.
