Claims
- 1. A photosensitive material comprising silver iodide produced by decomposing a solid electrolyte of the formula MAg4I5 having an ionic conductivity of >0.001 ohm−1 cm−1 in an organic solvent, where M is a monovalent cation, said photosensitive material further comprising a sensitizing agent selected from the group consisting of residual MAg4I5, MAg4I3, and mixtures of said residual MAg4I5 and said MAg4I3.
- 2. A photosensitive material according to claim 1, wherein M is Na+, K+, Rb+, Cs+ or NH4+.
- 3. A photosensitive material according to claim 2, wherein M is Rb+.
- 4. A photosensitive material according to claim 1 wherein said solid electrolyte of the formula MAg4I5 is formed by melting together stoichiometric amounts of MI and AgI, followed by cooling to solidify said MAg4I5.
- 5. A photosensitive material according to claim 1 wherein said decomposing is carried out in the presence of acetone.
- 6. A photosensitive material according to claim 1 wherein said silver iodide comprises β silver iodide.
- 7. A photothermographic element comprising the photosensitive material according to claim 1.
