Abstract (en)
[origin: EP0517053A1] By means of adding a diindolyl disulphide during the preparation of the emulsion, a rapidly developing and highly sensitive silver halide emulsion is obtained which is distinguished by a steep gradation, a small rise in fog during storage, an improved threshold gradation and low sensitivity to below-threshold pre-exposure.
