Spectral selective reflective image wall, for laser, LCD or CRT projection, comprises a cholesteric polymer layer

摘要

A spectral selective reflective image wall, comprising a cholesteric polymer layer, is new. An Independent claim is also included for production of a spectral selective reflective image wall by polymerization of a cholesteric polymer layer onto a substrate. Preferred Features: The substrate consists of plastic, textile and/or glass material, especially a plastic-impregnated textile sheet, and has three cholesteric polymer layers for blue, green and red light.
