Tetrachlorophthalic acid → Silver

Participants

Reaction Steps

A photothermographic silver soap dispersion was prepared as described in U.S. Pat. No. 5,434,043. A second ligand, tetrachlorophthalic acid, capable of coordination with silver was then added and allowed to exchange with the dispersed silver salt to form a shell of silver tetrachlorophthalate on the original core. Photothermographic films were then constructed also as described in U.S. Pat. No. 5,434,043.
