Direct-positive super-sensitized silver halide emulsions |
abstract |
Direct-positive silver halide emulsions comprising fogged silver halide grains and an electron acceptor are described wherein the emulsion is spectrally sensitized by means of 2-aryl-indolocarbocyanines. The combination of electron acceptors and these spectral sensitizers provides super-sensitizing effects that are not impaired by the presence of color couplers. |
