  • Silver halide emulsions which contain chloride, bromide, iodide or mixtures thereof as the halide.
  • Silver bromide and silver bromide iodide emulsions are generally used for more sensitive recording materials.
  • a disadvantage of the last-mentioned emulsions is that they have an intrinsic sensitivity in the blue spectral range. Therefore, in color recording materials, green and red sensitive layers are generally placed behind a filter that absorbs blue light. Furthermore, such emulsions are not as quickly developable as silver chloride emulsions.
  • Chloride-containing silver halide emulsions are also known, the grains of which have a layered structure. Such grains have a core and at least one layer which surrounds the core and whose properties differ from the core (core / shell emulsions).
