Definitions
- Example I was again repeated with the exception that the stabilizer 4-hydroxy-6-mercaptopyrazole(3,4d)pyrimidine was incorporated into a high contrast graphic art emulsion at a concentration of 100 cubic centimeters of the 1% by weight solution per 10 kilograms of emulsion with similar results. Development was carried out in a graphic arts developer identified as Ansco A-79 and having the following composition:
