<p>The present invention provides a curable coating composition comprising: a) at least one monomer chosen from polyol poly (meth) acrylate monomers having from 3 to 6 (meth) acrylate functions, b) at least one monomer chosen from polyol polyglycidyl ethers having at least three epoxy functions, c) at least one dysfunctional monomer, d) at least one free-radical photo-initiator, and e) at least one cationic photo-initiator, wherein the molar ratio of acrylate equivalents to epoxy equivalents in the composition ranges from 3:1 to 4:1, and wherein the composition is free of silica and of monomers bearing a silane function. It also provides a method for coating a substrate, such as an ophthalmic lens, with this composition, and to the coating substrate thus obtained.</p> |
