Abstract: A biodegradable display protector comprises a top layer; an antimicrobial (AF) layer beneath the top layer; a core layer formed of biodegradable material beneath the AF layer; an adhesive layer beneath the core layer; and a bottom release layer beneath the adhesive layer. The bottom release layer may be peeled off to allow the screen protector to be adhered to a display screen. In the embodiments, biodegradable polyethylene terephthalate (PET) or biodegradable polylactic acid (PLA) may be used for an inflexible protector whereas biodegradable thermoplastic urethane (TPU) may be used for a flexible protector. A thickness of the screen protector may be between about 0.08mm to about 0.23mm.

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.
