Since SD3057 without J aggregation is a green sensitive dye, Would it not be possible to create an RGB sensitive emulsion by aggregation of only some of the Ag halide-dye?.
I have never attempted to produce panchromatic emulsion with only one dye. But care with both concentration and mixing of the dye might make this possible.
Or, is my neighbor smoking something that is drifting over here? THAT is a real possibility. It ain't my fault. This is San Bernardino. Drugs are all over and used by people you would never suspect.
Even Retired Kodak engineers,PE.
