Lifetime of silver halide holographic materials comparative accelerating testing

Ultra fine grain panchromatic silver halide light sensitive material HP-P for RGB recording of reflection holograms have been recently developed. The average grain size is less than 10 nm, and recording energy for maximum diffraction efficiency for the spectral range 400-675 nm is in the frame of 0.5-2.5 mJ/cm2. To estimate the life time of the new material an accelerating testing at different temperatures (40°C, 60°C and 100°C) has been applied and compared with the results for the well known red sensitized silver halide emulsions HP-650, having average grain size about 10 nm. On the base of the obtained results according Arenious low at least three months life time of the new material at ambient conditions could be guaranteed, and more than six months at -5°C storage condition.
