| description | The preparation of a photo-sensitive salt dispersion having salts of sparing solubility in water which results in a material having a characteristic curve of the flatter gradient type by precipitating a sparingly soluble salt in a small first volume chamber which permits the reactants to be maintained with constant uniformity through the first chamber by stirring. Conducting the resultant dispersion through a conduit to a separated ripening chamber of a second volume many times that of the precipitating first volume. The silver halide emulsion is partially recycled from the separated ripening chamber through a conduit to the precipitation reaction which is outside of the second volume and where the recycled emulsion serves as reaction medium for the further precipitation of further silver halide salts. |
