摘要:
A photographic developing apparatus of the type in which development is effected by passing exposed sensitive material (principally one for printing such as photographic paper) successively through a developing vessel, a bleaching/fixing vessel, and a rinsing vessel. The bleaching/fixing vessel is replenished with a mixture of concentrated processing liquid and liquid extracted from the rinsing vessel, so that the amount of processing liquid discharged from the rinsing vessel as overflow is reduced, thereby alleviating the burden of waste liquid disposal.When the exposed sensitive material to be processed is principally one for photographing such as negative film or reversal film, the material is successively passed through a developing vessel, a bleaching vessel, a fixing vessel, and a rinsing vessel, or through a developing vessel, a bleaching vessel, a bleaching/fixing vessel, and a rinsing vessel, so that concentrated processing liquid and liquid extracted from the rinsing vessel are supplied to the fixing vessel or the bleaching/fixing vessel which is immediately before the rinsing vessel.
摘要:
In a photographic processing apparatus for immersing and developing an exposed light sensitive material in a developer contained in a developing tank, the temperature of the developer is detected and an evaporation amount of the developer corresponding to an elapsed time period is estimated on the basis of the temperature detected. Then, a replenishment water is supplied to the developing tank by the amount based on this estimated evaporation amount. Consequently, an optimum concentration of the developer in the developing tank can be maintained, thereby preventing a change in the developing characteristics.

摘要:
In a processing method wherein, after a silver halide color photographic material is subjected to color development, the silver halide color photographic material is desilvered and then washed and/or stabilized, a photographic material that has at least one high-silver chloride emulsion layer, and in which at least one emulsion layer contains a monodisperse emulsion, is rapidly processed with a color developer having a water-soluble high polymer compound. The coating amount of silver of the said silver halide color photographic material is preferably 0.75 g/m2 or less, and the color developer contains chloride ions in an amount of 0.035 mol/liter or more. In continuous and rapid processing, fluctuations of photographic properties (particularly changes in sensitivity and gradation) are remarkably reduced, the ununiformity of developed density is remarkably improved, and the occurrence of a deposit on a processing tank wall surface is prevented.

摘要:
A method for continuously processing an image-wise exposed silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer containing 95 mol % or more of silver chloride is disclosed, which comprises the steps of developing the silver halide color photographic material in a color developer and supplying a replenisher to the color developer, the replenisher comprising used color developer and a regenerant wherein components accumulated to the color developer during the continuous processing are not removed from the replenisher. This method does not require a large scale apparatus and provides stable photographic properties without substantially producing waste water and without causing crystallization of chemicals in a replenisher even after repeated regeneration, particularly when varying the amount of light-sensitive material being processed per unit time.

摘要:
Processing a silver halide color photographic material comprising color developing, desilvering and water washing and/or stabilizing. In this process, a photographic material which has at least one emulsion layer containing a high silver chloride content, and at least one emulsion layer containing a monodisperse emulsion, is continuously processed with a color developing solution containing a water-soluble high polymer compound. The coated amount of silver in the photographic material is preferably 0.75 g/m.sup.2 or less. The color developing solution preferably has a chloride ion content of 0.035 mol/l or more. The water soluble high polymer compound can be a polyester, polyamide, polyurethane, polyether, polycarbonate or a natural high polymer compound, or their derivatives. It is obtained by polymerizing or copolymerizing a monomer containing a copolymerizable ethylene type unsaturated group. The high polymer compound is preferably added in the amount of 0.001-10 g per liter of the color developing solution. By using this process, fluctuations in photographic properties is remarkably reduced, uniformity in developed density is remarkably improved, and the prevention of deposits on the processing tank wall surface is improved.
