Definitions
- the invention relates to a photothermographic silver halide material and.method for producing in such a material improved fog stability on shelf aging by incorporating dithioethers with two or more terminal hydroxy groups.
- Silver halide photothermographic imaging materials often referred to as "dry silver" compositions because no liquid development is necessary to produce the final image, have been known in the art for many years. These imaging materials basically comprise a light insensitive, reducible silver source, a light sensitive material which generates silver when irradiated, and a reducing agent for the silver source.
- the light sensitive material is generally photographic silver halide which must be in catalytic proximity to the light insensitive silver source. Catalytic proximity is an intimate physical association of these two materials so that when silver specks or nuclei are generated by the irradiation or light exposure of the photographic silver halide, those nuclei are able to catalyze the reduction of the silver source by the reducing agent.
- silver is a catalyst for the reduction of silver ions and the silver-generating light sensitive silver halide catalyst progenitor may be placed into catalytic proximity with the silver source in a number of different fashions, such as partial metathesis of the silver source with a halogen-containing source (e.g., U.S. Pat. No. 3,457,075), coprecipitation of the silver halide and silver source material (e.g., U.S. Pat. No. 3,839,049), and any other method which intimately associates the silver halide and the silver source.
- a halogen-containing source e.g., U.S. Pat. No. 3,457,075
- coprecipitation of the silver halide and silver source material e.g., U.S. Pat. No. 3,839,049
- Photothermographic emulsions in a manner similar to photographic emulsions and other light sensitive systems, tend to suffer from fog. Fog is spurious image density which appears in unexposed areas of the element and is often reported in semitometric results as D min .
- Traditionally, photothermographic materials have suffered from fog instability on shelf aging. The fog level rises steadily as the materials reach extended age such as one year at room temperature (ambient conditions). Adding to the difficulty of fog control on shelf aging is the fact that the developer is incorporated in the photothermographic element, which is not the case in most silver halide photographic systems. The need for shelf life extenders in photothermographic elements is therefore considered to be very important.
- the fog level of freshly prepared photothermographic materials will be referred to as initial fog.
- a great deal of effort has been directed towards minimizing the initial fog and stabilizing the fog level on shelf aging.
- Mercuric salts are described as antifoggants in U.S. Pat. No. 3,589,903.
- Fog reduction has been described for organic carboxylic acids such as benzoic and phthalic acids in U.S. Pat. No. 4,152,160, for benzoyl benzoic acid compounds in U.S. Pat. No. 4,784,939, for indane or tetralin carboxylic acids in U.S. Pat. No. 4,569,906, for dicarboxylic acids in U.S. Pat. No.
- Halogenated compounds have also been shown to be strong antifoggants and are described in U.S. Pat. Nos. 4,546,075, 4,756,999, 4,452,885, 3,874,946 and 3,955,982.
- Halogen molecules or halogen molecules associated with a heteroatom ring are also useful antifoggants and are described in U.S. Pat. No. 5,028,523.
- Other materials finding applications as photothermographic antifoggants include palladium compounds found in U.S. Pat. No. 4,102,312 and G.B. Pat. No. 1,502,670; iron group metals found in U.S. Pat. No.
- the generation of fog, in particular on shelf aging, in photothermographic elements comprising photosensitive silver halide, organic silver salt oxidizing agent and reducing agent for silver ion can be reduced by the addition of a dithioether with two or more terminal hydroxy groups as defined by formula (I).
- the organic linking groups may be alkyl, aryl, alkene, heteroaromatic or mixed groups (e.g. arylalkyl groups).
- the aryl or heteroaromatic ring may also carry substituents being selected from the class consisting of halogen (e.g., Br and Cl), hydroxy, amino, carboxy, alkyl and alkoxy.
- substituents being selected from the class consisting of halogen (e.g., Br and Cl), hydroxy, amino, carboxy, alkyl and alkoxy.
- alkyl group includes ether groups (e.g., CH3-CH2-CH2-O-CH2-), haloalkyls, nitroalkyls, carboxyalkyls, hydroxyalkyls, sulfoalkyls, etc. while the term alkyl includes only hydrocarbons. Substituents which react with active ingredients, such as very strongly electrophilic or oxidizing substituents, would of course be excluded as not being inert or harmless.
- dithioethers with two or more terminal hydroxy groups are set forth below, but the present invention should not be construed as being limited thereto.
- the antifoggants are used in a general amount of at least 0.001 moles per mole of silver. Usually the range is between 0.01 and 5 moles of the compounds per mole of silver and preferably between 0.02 and 0.6 moles of compounds per mole of silver.
- the photothermographic emulsions of this invention may be constructed of one or more layers on a substrate.
- Single layer constructions must contain the silver source material, the silver halide, the developer and binder as well as optional additional materials such as toners, coating aids, and other adjuvants.
- Two-layer constructions must contain the silver source and silver halide in one emulsion layer (usually the layer adjacent to the substrate) and some of the other ingredients in the second layer or both layers, although two layer constructions comprising a single emulsion layer containing all the ingredients and a protective topcoat are envisioned.
- Multicolor photothermographic constructions may contain sets of these bilayers for each color, or they may contain all ingredients within a single layer as described in U.S. Pat. No. 4,708,928. In the case of multilayer multicolor photothermographic articles the various emulsion layers are generally maintained distinct from each other by the use of functional or non-functional barrier layers between the various photosensitive layers as described in U.S. Pat. No. 4,460
- mercury (II) salts While not necessary for practice of the present invention, it may be advantageous to add mercury (II) salts to the emulsion layer(s) as an antifoggant.
- Preferred mercury (II) salts for this purpose are mercuric acetate and mercuric bromide.
- the light sensitive silver halide used in the present invention may typically be employed in a range of 0.75 to 25 mol percent and, preferably, from 2 to 20 mol percent of organic silver salt.

- the silver halide may be in any form which is photosensitive including, but not limited to cubic, orthorhombic, tabular, tetrahedral, etc., and may have epitaxial growth of crystals thereon.
- the silver halide used in the present invention may be employed without modification. However, it may be chemically sensitized with a chemical sensitizing agent such as a compound containing sulfur, selenium or tellurium etc., or a compound containing gold, platinum, palladium, rhodium or iridium, etc., a reducing agent such as a tin halide, etc., or a combination thereof.
- a chemical sensitizing agent such as a compound containing sulfur, selenium or tellurium etc., or a compound containing gold, platinum, palladium, rhodium or iridium, etc.
- a reducing agent such as a tin halide, etc.
- the silver halide may be added to the emulsion layer in any fashion which places it in catalytic proximity to the silver source.
- Silver halide and the organic silver salt which are separately formed or "preformed” in a binder can be mixed prior to use to prepare a coating solution, but it is also effective to blend both of them in a ball mill for a long period of time. Further, it is effective to use a process which comprises adding a halogen-containing compound in the organic silver salt prepared to partially convert the silver of the organic silver salt to silver halide.
- preformed silver halide emulsions of this invention can be unwashed or washed to remove soluble salts.
- the soluble salts can be removed by chill-setting and leaching or the emulsion can be coagulation washed, e.g., by the procedures described in U.S. Pat. Nos. 2,618,556; 2,614,928; 2,565,418; 3,241,969; and 2,489,341.

- the topcoat solutions were coated over the silver layer at a dry weight of 3.0 g/m2. The layer was dried at 175°F for four minutes.
- the coated materials were then exposed with a laser sensitometer incorporating a 780 nm diode. After exposure, the film strips were processed at 260°F for ten seconds. The images obtained were evaluated by a densitometer. Sensitometric results include D min , D max , speed (relative speed at a density of 1.0 above D min versus a control without additive set at 100) and average contrast (Cont, measured as the slope of the line joining density points of 0.25 and 2.0 above D min ). The sensitometry was evaluated shortly after coating (initial) and after shelf aging at room temperature.
- AF-1 3,6-Dithia-1,8-octanediol
- Table 1 The results are compiled in Table 1 and show that 3,6-Dithia-1,8-octanediol (AF-1) is an effective antifoggant and can greatly reduce the fog increase that occurs during shelf aging for these infrared sensitized photothermographic materials. Contrast retention on shelf aging was also improved by AF-1 (example A versus 2, 3 and 4).
- Table 1 also includes a combination of 3,6-Dithia-1,8-octanediol (AF-1) with a vinyl sulfone. This combination may lead to further improvements in shelf aging of photothermographic materials.
