Definitions
- the present invention relates to a fixing composition for a photographic silver halide light-sensitive element, and more particularly to an improved quick fixing composition for a photographic silver halide light-sensitive element.
- a fixing composition is used for the latter processing, and for this purpose, various thiosulfates, such as sodium thiosulfate are employed.
- ammonium thiosulfate which dissolves the silver halide more quickly than sodium thiosulfate has frequently been used.
- An ammonium thiosulfate type fixing composition is effectively employed for processing a photographic light-sensitive element having a thick silver halide emulsion layer, such as, a photographic X-ray film.
- the fixing speed of an ammonium thiosulfate-type fixing composition is markedly influenced by the type of developing composition used.
- a large amount of an alkaline material such as potassium carbonate or potassium hydroxide, is used in a developer as a developing accelerator, but when employing such a potassium salt, the fixing speed of an ammonium thiosulfate-type fixing composition is reduced to a greater extent than when employing a sodium salt as the alkaline material.
- potassium bromide is widely employed as an anti-foggant, however, the fixing speed is also reduced by the presence of potassium bromide. 1
- liquid photographic processing chemicals have been utilized.
- a liquid processing composition having a high concentration is desirable.
- the amount of chemicals used in development is increased and, a highly concentrated liquid developer tends to be widely employed as more convenient.
- the concentration of the liquid developer generally depends on the solubility of the alkaline material which comprises a large porportion of the developer. Since the solubility of potassium salts (such as potassium carbonate and potassium hydroxide) is higher than that of sodium salts, such potassium salts are frequently employed in a liquid developer. However, when processing photographic light-senstive films which have been developed in a liquid developer containing the above-mentioned potassium salts in an ammonium thiosulfate type fixing composition, there is a marked reduction in fixing speed. This Will cause problems when conducting the development using an automatic developing machine.
- potassium salts such as potassium carbonate and potassium hydroxide
- an object of this invention is to provide a fixing composition containing ammonium thiosulfate capable of fixing at high speeds a photographic silver halide light-sensitive element which has been developed in a liquid developer. Best results are obtained when the developer has contained a potassium salt.
- R and R represent a member selected from the group consisting of a hydrogen atom, an amino group, an alkyl group, a hydroxyalkyl group, an aryl group, and an allyl group.
- R generally represents a member selected from the group consisting of a hydrogen atom, an alkyl group, a hydroxyalkyl group and an allyl group.
- R and R may combine to form a heterocyclic ring, in which case it is necessary that R not be an allyl group.
- an ammonium thiosulfate-type fixing composition for photographic silver halide light-senstive elements containing a compound represented by the general formula wherein R and R each represents a hydrogen atom, an amino group, an alkyl group, a hydroxyalkyl group, an aryl group or an allyl group; said R and R may combine to form a heterocyclic ring; and R represents a hydro gen atom, an alkyl group, a hydroxyalkyl group or an allyl group when R and R do not form a heterocyclic ring, but represents a hydrogen atom, an alkyl group or a hydroxyalkyl group when R and R form a heterocyclic ring, i.e., in this case R may not be an allyl group.
- a highly-sensitive silver iodoa'bromide film was image Water to make 1 liter.
- the photographic film thus developed was processed in a fixing solution having the following composition:
