Publication number: 20230358934Abstract: An integral multilayer optical film includes a plurality of interference layers; a structured layer disposed on the interference layers and including a plurality of particles dispersed in a binder; and a barrier layer disposed between the structured layer and the interference layers and co-extruded with the interference layers and the structured layer. The structured layer has a first major surface facing away from the interference layers and a second major surface facing the interference layers. The barrier layer causes the particles to impart a greater surface roughness to the first major surface than the second major surface so that when the optical film is illuminated with a light source, the optical film has a first average effective transmission T1 when the first major surface faces the light source and a second average effective transmission T2 when the first major surface faces away from the light source, where T1-T2?5%.Type: ApplicationFiled: September 9, 2021Publication date: November 9, 2023Inventors: Carl A.
