A holographic material is investigated which uses an incorporated hardening developer in a fine grain silver halide emulsion to first obtain a hardening modulation in the gelatin, and then convert the hardening modulation to a refractive index modulation by alcohol dehydration similar to the dichromated gel process. The hardening modulation is observed but conversion to a refractive index modulation by alcohol dehydration is not seen. The feasibility and problems of the material are evaluated.
