DuPont has developed photopolymer materials for recording volume phase holograms. These unique materials record the complete wavefront of light from an object as a periodic refractive index modulation throughout the thickness of the film. Materials have been designed and developed for reflection and transmission holograms for a variety of applications. Recently, new materials with panchromatic sensitivity, designed specifically for color display holography, have been developed. This paper presents DuPont's new color material designed for reflection display holography. An overview of the recording mechanism, holographic performance, and process of use is given. Experimental color balancing results are discussed, and performance is compared to that of a film with different color balancing characteristics.
