A new ultra-fine grain silver halide photofilm for pulsed colour holography has been developed. The film is now being manufactured on an industrial basis and is commercially available. The photo-emulsion used has an average silver grain size of 10 nm and is sensitive to emissions at 440 nm, 532 nm and 660 nm – the emission wavelengths of the pulsed lasers commonly used in modern digital holographic printers. In the article we present the basic characteristics of the new material.
