Abstract
An infrared light transmission film includes a polymer matrix and at least one red colorant, blue colorant, and yellow colorant that are uniformly dispersed in the polymer matrix at amounts effective to allow transmission through the film of at least about 85% of light with wavelengths over about 800 nm while blocking transmission of at least about 90% of light with wavelengths less than about 750 nm.
