Abstract
A tabular silver halide emulsion wherein the tabular grains account for more than 75% of the total grain projected area said emulsion comprising silver halide grains nucleated in the presence of nucleation peptizer and thereafter grown in the presence of growth peptizer, wherein at least one of the peptizers is substantially pure collagen like material prepared by genetic engineering, said peptizer having an amino acid sequence comprising more than 4 different amino acids. A process of preparing the AgX emulsion.
