Definitions
- the covering power of photosensitive photographic silverhalide preparations can be increased by adding lactose to the photosensitive layer and/or to the auxiliary layers, e.g., sublayers, filter layers and anti-abrasion layers, with no occurrence of the drawbacks mentioned above. Addition of lactose then not only enhances covering power, but also substantially diminishes fogging. These results are wholly unexpected and were in no way predictable. As is known in the art, lactose is not even a macromolecular compound, but has a comparatively low molecular weight and is also characterized by substantial solubility in water. Hence, from this it would be expected that the lactose would be leached out of the film layers during processing so that its effect would be lost.
- lactose is not even a macromolecular compound, but has a comparatively low molecular weight and is also characterized by substantial solubility in water. Hence, from this it would be expected that the lactose would be leached out of the film layers during processing so
- the present invention offers the possibility of employing a low-molecular substance for the specified purpose, with the advantage that it does not affect the viscosity of the emulsion.
- reducing agents to photosensitive emulsions 3,185,569 Patented May 25, 1965
- Preparation of the emulsions according. to this invention may be carried out by the usual methods.
- the lactose is added to the emulsion in amounts of 5 55 g. per liter, the addition being advantageously effected either before finishing the emulsion or immediately before coating the film. Addition may, however, be effected at any other time as maybe desired during the emulsification process.
- lactose to the photosensitive layer and/ or to the auxiliary layers in amounts of 5-55 g. to 20-100 g. of silver bromide.
- the gelatino-silver halide emulsions of the invention contain at least 20% by weight of lactose based on silver halide. On a dry basis, the lactose-containing gelatinosilver halide emulsions contain 35% to 70% silver halide, 20% to 60% gelatin, and 5% to 40% lactose, all by weight.
- the process is applicable to all silver halide: gelatin emulsions but is particularly effective in coarse-grained high-sensitivity emulsions.
- the lactose can be added to gelatin silver chloride, silver bromide, silver iodobromide, silver chlorobromide and other simple and mixed silver halide emulsions.
- the final emulsions can contain any of the wellknown optical sensitizing dyes as well as non-optical sensitizers such as sulphur sensitizers, e.g., allyl isothiocyanate, allyl diethyl thiourea, phenyl isothiocyanate and sodium thiosulfate; the polyoxyalkylene ethers disclosed in Blake et al., U.S.
- Other non-optical sensitizers such as amines as taught by Staud et al., U.S. Patent 1,925,508 and metal salts as taught by Baldsiefen, U.S. Patent 2,540,085 and Baldsiefen et al., U.S. Patent 2,540,086 may also be used.
- Antifoggants e.g., benzotriazole and triazaindenes can be used as well as the usual hardeners, i.e., chrome alum, formaldehyde, etc.
- the modified lactose-containing gelatino-silver halide emulsions may be coated on any suitable support such as paper or films composed of cellulosic esters, e.g., cellulose triacetate, cellulose acetate/butyrate; superpolymers, e.g., polyvinyl chloride co vinyl acetate, polyvinyl acetals, e.g., formal and acetal; polystyrene, polyamides, e.g., polyhexamethylene adipamide, and polyesters, e.g., polyethylene terephthalate, polyethylene terephthalate/ isophthalate and those polyesters obtainable by condensing terephthalic acid or dimethyl terephthalate with propylene glycol, diethylene glycol, tetramethylene glycol or cyclohexane-1,4-dimethanol (hexahydro-p-xylene alcohol).
- lactose may be used in emulsions according to this invention. Because of its low price, it has substantial commercial superiority over the dextrans.
- Lactose 40 g. per kg. of emulsion ready for coating, is added to emulsion B while no lactose is added to emulsion A.
- the emulsions are cast on a film base, yielding films A and B.
- a Wedge pattern was copied on each of these films. They were developed in a developer having the composition:
- a photographic gelatin-silver halide emulsion layer containing on a dry basis to 70% silver halide, 20% to 60% gelatin and 5% to lactose, all by weight.
- a photographic element comprising a gelatino-silver halide emulsion layer having in intimate association therewith 5 to 22 grams of lactose per 20 to 100 grams of silver halide.
- a photographic element comprising a gelatino-sil- -ver halide emulsion layer having in intimate association therewith on a dry basis 35% to 70% silver halide, 20% to gelatin, and 5% to 40% lactose, by weight.
