PUBLISHED OCTOBER 21, 1969 825,478 DRY PROCESSED PHOTOGRAPHIC MATERIALS CONTAINING PREPROCESSING STABILIZERS Ralph W. Baxendale and George F. L. Wood, both Kodak Park Division, Rochester, N.Y. 14650 Filed Mar. 28, 1969. Published Oct. 21, 1969 Int. Cl. G03c 5/30 U.S. CI. 96-66 No Drawing. 14 Pages Specification The presence of a hydroxybenzoic acid compound in heat processed photographic materials improves the preprocessing stability. Such hydroxybenzoic acid compounds can be described by the formula:
0 i i-(FR wherein R is hydrogen, alkyl, especially alkyl containing 1 to 5 carbon atoms such as methyl, ethyl, propyl, butyl and pentyl or alkali and alkaline earth metals such as lithium, sodium, potassium, calcium, strontium and barium; R is hydrogen, alkyl, especially alkyl containing 1 to 5 carbon atoms such as methyl, ethyl, propyl, butyl and pentyl or alkoxy, especially alkoXy groups containing 1 to 5 carbon atoms such as methoxy, ethoxy, propoxy, butoxy and pentyloxy; and n is 1, 2 or 3. Typical examples of such compounds include gallic acid, 2,4,6- trihydroxybenzoic acid, gentisic acid, methyl gallate, propyl gallate, and the like.
The hydroxybenzoic acids are efiective as preprocessing stabilizers in materials for dry processing which comprise a photographic silver salt and a silver salt stabilizer precursor. In addition, the heat processed photographic materials can contain activator precursors and incorporated developing agents.
