The need for ultra-fine-grain silver halide emulsion for recording colour holograms is explained. The lack of suitable commercial materials for colour holography was the reason behind the European SilverCross project. The two-year RD project is introduced with its expected outcome. The work carried out by one of the seven partners NEWI/CMO is described. A range of experimental panchromatic silver halide emulsions have been produced and tested. High-quality materials with a low-level blue light scattering and good colour rendition have been obtained. Work on improving the current formula and procedure is in progress in order to increase the sensitivity and the stability of the emulsion.
