Holography with a new photopolymer system, DMP-128, will be described. Films of DMP-l28 are coated on either solid or flexible substrates from an aqueous solvent. The resulting films, when stored dry, have a shelf life that exceeds nine months. The dry films are inactive and must be incubated for a few minutes in an environment of approximately 50% rh before laser exposure. Recording is possible with eitheF blue (442nm, 488nm), green (514nm), or red (633nm, 647nm) laser light. Exposure of 5mj/cm is sufficient for high diffraction efficiency (80%-95%) transmission holograms, while 30mj/cm2 is required for bright reflection holograms. It is not necessary to exclude atmospheric oxygen during hologram recording. Refractive index modulation of 0.03 is routinely achieved. After laser exposure a uniform white light illumination is used to complete the photo-polymerization. A single processing bath yields holograms with good environmental stability. An additional processing bath yields images with exceptional resistance to high humidity.
