| titleOfInvention | Photographic color developing composition containing calcium ion sequestering agent combination and method of use |
| abstract | Concentrated and working strength photographic color developing compositions are stabilized with the inclusion of two specific types of calcium ion sequestering agents. One of the sequestering agents is a polyelectrolyte such as a polycarboxylic acid or salt thereof having a molecular weight of from about 2000 to about 100,000. The other one is a non-polymeric aminocarboxylic acid, polyphosphonic acid, or a salt thereof. The weight ratio of the first calcium ion sequestering agent to the second calcium ion sequestering agent is from about 1:1 to about 20:1. These compositions can be used to process color photographic materials such as color photographic papers. |
