Zusammenfassung:	Optically clear adhesives (OCA) with UV blocking below 380 nm are described. The OCA comprise a UV blocking package of UV absorbers and hindered amine light stabilizers. The UV blocking package is suitable for a variety of OCA, including PIB-based OCA, styrenic block copolymer-based OCA, silicone-based OCA, or acrylic-based OCA. The OCA with UV blocking in the invention are particularly suitable as laminating films, tapes or encapsulants for adhering display electronic devices, e.g., LCD displays, LED displays, flexible and foldable displays, and touch screens.
