| titleOfInvention |
Multiple-speed photographic emulsion containing an organic compound oxidizable to a spectral-sensitizing dye |
| abstract |
A MULTIPLE-SPEED PHOTOGRAPHIC EMULSION IS PROVIDED BY INCORPORATING A COLORLESS DYE PERCURSOR IN A PHOTOGRAPHIC SILVER HALIDE EMULSION. AFTER EXPOSURE, THE EMUSLION IS DEVELOPED AND A NORMAL PHOTOGRAPHIC IMAGE IS OBTAINED, DURING THE COURSE OF DEVELOPMENT, THE DYE PERCURSOR IS CONVERTED INTO AN ACTIVE SPECTRAL SENSITIZING DYE IN THE AREAS OF EXPOSURE. IF HIGHER PHOTOGRAPHIC SPEED IS DESIRED, THE ELEMENT IS THEN UNIFORMLY REEXPOSED TO RADIATION CORRESPONDING TO THE SENSISTIVITY OF THE SPECTRAL SENSITIZING DYE AND DEVELOPMENT IS CONTINUED TO OBTAIN AN AMPLIFIED IMAGE CORRESPONDNG TO A RELATIVELY HIGHER SPEED. |
