Abstract

A primer coating composition for bonding a functional laminate to a lens during cast-polymerization, including an acrylic polymer; a urethane acrylate oligomer; a reactive component capable of reacting with a lens-casting monomer for casting the cast-polymerized lens, a UV initiator or a thermal initiator, and a solvent. A method for cast-polymerizing a lens, including applying the primer coating composition to at least one external surface of a functional laminate; cutting and forming the functional laminate, placing the shaped functional laminate to which the primer coating is applied and a monomer for casting a lens in a casting cell so that the monomer contacts the primed surface of the functional laminate, and cast-polymerizing the monomer in the casting cell. An ophthalmic lens, including a cast-polymerized lens including at least one polymer, a functional laminate, and a primer coating obtained by curing the primer coating composition and deposited on at least one external surface of the functional laminate.
