| titleOfInvention | Suppressing calcium ions in developer |
| abstract | Calcium ions present in photographic processing solns., are suppressed by treating exposed silver halide material with a soln. contg. triethylene tetraminehexaacetic acid or its alkali salt. The agent may be added to developer, pre-hardener, neutralizing soln. or other baths. Developer may be hydroquinone, 1-phenyl-3-pyrazolidone, monomethyl-p-aminophenol or their derivs. |
