| titleOfInvention | Photothermographic composition including a mixture containing benzyl alcohol or 2-phenoxyethanol speed-increasing solvent and an aromatic hydrocarbon solvent |
| abstract | Abstract of the Disclosure In a photothermographic silver halide composition capable of being coated on a support comprising a hydro-philic photosensitive silver halide emulsion containing a gelatino peptizer with an organic solvent mixture, a hydro-phobic binder and an oxidation-reduction image-forming composition comprising (1) a silver salt of a long-chain fatty acid with (11) an organic reducing agent for said silver salt of a long-chain fatty acid, improvements are provided by a solvent mixture comprising a combination of (A) an alcohol photographic speed-increasing solvent which is a compound selected from the group sonsisting of benzyl alcohol photographic speed-increasing solvents and 2-phenoxyethanol speed-increasing solvents with (B) an aromatic hydrocarbon solvent that is compatible with the alcohol solvent said (C) 0 to 10% by weight of the solvent mixture of said hydrophobic binder. The discribed photo-thermographic composition can be prepared by very thoroughly mixing, such as ultrasonic wave mixing, (I) a hydrophilic photosensitive silver halide emulsion with (II) an organic solvent mixture comprising described (A), (B) and (C), and then very thoroughly mixing the resulting product with (III) comprising (a) a hydrophobic binder and (b) an oxidation-reduction image-forming composition comprising (i a silver salt of a long-chain fatty acid with (ii) an organic reducing agent, typically in an organic solvent. The photothermographic composition can be coated on a suitable support to provide a photothermographic element. |
