Definitions

  • the invention relates to a method for developing photographic silver halide recording materials, in particular for use in X-ray diagnostics and in reproduction technology.
  • the invention has as its object the development process for silver halide recording materials which contain nonionic fluorine Contain surface-active substances, so that the occurrence of the described error is avoided.
  • This object is achieved by a method for developing photographic silver halide recording materials which contain nonionic fluorinated surface-active substances with a developer which contains at least 15 g / l of a dihydroxybenzene developer substance and at least 0.15 mol / l of an alkali metal sulfite at a pH of at most 11 , 5, which is characterized in that the developer contains a wetting agent in a concentration of at least 0.1 g / l dissolved.
  • the object is also achieved by using a developer which, at a pH of at most 11.5, contains at least 15 g / l of a dihydroxybenzene developer compound, at least 0.15 mol / l of an alkali metal sulfite and at least 0.1 g / l of one Contains wetting agent in dissolved form for the spot-free development of photographic silver halide recording materials which contain nonionic fluorinated surface-active substances
  • the wetting agent should be selected so that it is clearly soluble in the developer solution in a concentration of at least 0.1 g / l. Wetting agents that are only dispersed are not suitable because they in turn promote the formation of sludge and can contaminate the developed materials. Basically there is no upper limit for the concentration; for practical reasons (foam formation, costs), 10 g / l should not be exceeded.
  • Anionic wetting agents are preferably used to carry out the process according to the invention. These are generally more readily soluble in the slightly alkaline developer solution than cationic or nonionic substances. In addition, they generally affect the photographic result less than cationic wetting agents.
  • a preferred concentration range for the wetting agent is above 0.5 g / l.
  • wetting agents have proven particularly useful for carrying out the method:
  • the fluorine-containing nonionic surface-active substances used in the invention have molecules which are preferably composed of a polyalkylene oxide and a partially or fully fluorinated alkyl or aralkyl part which are connected by a bridge, for example an ether or sulfonecarbamide bridge.
  • the concentration of the wetting agent in the developer solution generally decreases more or less rapidly during use by discharge and regeneration. This applies in particular to low initial concentration values. It may therefore be advantageous, depending on the material throughput, to meter an aqueous solution of the wetting agent into the development tank or into the regenerate line in order to maintain a uniformly low concentration.
  • the process according to the invention makes it possible to make unlimited use of the advantageous effects of the nonionic fluorinated surface-active substances on the properties of the photographic silver halide materials.
  • the method according to the invention can be used when using photographic silver halide recording materials, in particular in medical diagnostics with X-rays and in reproduction technology.
  • a silver iodobromide emulsion the crystals of which had an average grain volume of 0.4 ⁇ m3 and an iodide content of 2 mole percent, was applied to both sides of a polyethylene terephthalate support.
  • the emulsion contained 100 g of gelatin per mole of silver and usual additives for chemical sensitization and stabilization as well as usual coating aids.
  • the silver coating weight on each side was 2.6 g / m2.
  • On both sides of the emulsion layer was a protective gelatin layer with a Application weight of 1.3 g / m2 applied.
  • the protective layer also contained a nonionic fluorine-containing surface-active substance, as indicated in the table for the various, otherwise identical, samples.
  • the developed film sheets were examined for the presence of white spots with the aid of a light box. The results are shown in the table at the end of the description.
