The films include alternating polymeric layers configured to selectively reflect and transmit visible light at a design angle of incidence, where the selective reflection includes first and second visible reflection bands. At

대표청구항 ▼

What is claimed is: 1. A multilayer optical film comprising alternating polymeric layers configured to selectively reflect and transmit visible light at a design angle of incidence, the selective reflection comprising first and second visible reflection bands, wherein at least one of the first and second visible reflection bands is a first-order reflection. 2. The film of claim 1, wherein the film is further configured to selectively reflect infrared light in an infrared reflection band at the design angle of incidence. 3. The film of claim 2, wherein the first visible reflection band comprises a first-order reflection and the second visible reflection band is an overtone of the infrared reflection band. 4. The film of claim 1, wherein the alternating polymeric layers comprise at least a first and second distinguishable set of alternating polymeric layers, and further wherein the reflection bands correspond respectively to the at least first and second sets of layers. 5. The film of claim 4, wherein the first set of layers comprises an f-ratio of less than about 0.5. 6. The film of claim 5, wherein the second set of layers comprises an f-ratio of about 0.5. 7. The film of claim 5, wherein the first set of layers comprises an f-ratio of less than about 0.3. 8. The film of claim 4, wherein the first set of layers comprises an f-ratio of greater than about 0.5. 9. The film of claim 8, wherein the second set of layers comprises an f-ratio of about 0.5. 10. The film of claim 8, wherein the first set of layers comprises an f-ratio of greater than about 0.7. 11. The film of claim 1, wherein the first and second visible reflection bands have bandwidths of about 50 nm or less. 12. The film of claim 1, wherein the selective reflection for visible light further comprises a third visible reflection band. 13. The film of claim 12, wherein the film is further configured to selectively reflect infrared light in an infrared reflection band at the design angle of incidence, and further wherein the first and third visible reflection bands are overtones of the infrared reflection band.
