Abstract:
The present disclosure generally relates to patterned gradient polymer films and methods for making the same, and more particularly to patterned gradient optical films that have regions that include variations in optical properties such as refractive index, haze, transmission, clarity, or a combination thereof. The variation in optical properties can occur across a transverse plane of the film as well as through a thickness direction of the film.
