摘要:
The present invention relates to a method in which water for preventing the concentration of processing solution in a processing tank from being increased due to evaporation and a replenisher for avoiding a lowering of the effectiveness of the processing solution are added to the processing tank of a photographic processing apparatus. Before the processing tank is replenished with a replenisher, the processing tank is replenished with water by an amount corresponding to the amount of water evaporated therefrom until the liquid surface level reaches the original liquid surface level i.e. replacing evaporated water, and then, the processing tank is replenished with replenisher. Thereafter, the processing solution is discharged by an amount equal to the amount of replenisher added in order to return the liquid surface level to the original liquid surface level. Thus, the performance of the processing solution can be restored while the concentration of the processing solution is kept constant.
摘要:
A method for processing silver halide photosensitive materials comprises replenishing each of replenishers to water washing process and/or stabilization process in an amount of 1 to 50 times the volume of a solution carried over from a bath preceding the water washing process and/or the stabilization process per unit area of the photosensitive material and limiting the amount of calcium compounds included in a layer for constituting photograph of the photosensitive material to not more than 25 mg/m.sup.2 on the basis of the weight of elemental calcium. The method makes it possible to effectively suppress the contamination of the processed photosensitive materials, the increase in turbidity of the water washing and/or stabilization bath solutions and the proliferation of bacteria or molds in these baths. These effects are further enhanced by reducing the amount of calcium and magnesium present in the replenishers for washing and/or stabilization.

A method for processing a silver halide color photographic photosensitive material comprises treating a silver halide photographic material with a bath having fixing ability and then washing with water and/or stabilizing the photosensitive material and characterized in that the amount of replenisher for water washing or stabilization is controlled so that it is 1 to 50 times the volume of liquid carried over by the photosensitive material processed from the bath preceding the water washing bath or the stabilization bath and that the photosensitive material comprises, for instance, compounds (13): ##STR1## The method makes it possible to substantially keep the image performance of the photosensitive material processed high while substantially saving the amount of washing water or the stabilization liquid and substantially shortening the water washing or the stabilization time.
摘要:
A method for processing a silver halide color photographic material is disclosed, comprising after development, bleaching or bleach-fixing an imagewise exposed silver halide color photographic material in the presence of at least one compound represented by formula (I): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom or an alkyl group, or R.sup.1 and R.sup.2 may combine with each other to form a heterocyclic ring; A.sup.1 and A.sup.2, which may be the same or different, each represents an alkylene group having from 2 to 5 carbon atoms which may be substituted; and n represents an integer from 2 to 6.In accordance with the method of the present invention, as a result of accelerated bleaching function, the processing time is shortened while sufficient bleaching is performed, thus providing color photographic images of excellent image quality.

摘要:
In photographic processing apparatus for developing, bleaching-fixing and washing photographic materials, a predetermined quantity of fresh wash water is supplied into a washing tank every time a predetermined amount of the photographic materials have been washed. The fresh wash water is provided by deionizing city water and is reservoired in a replenisher tank. In order to detect a predetermined loss of the fresh wash water in the replenisher tank, a conductivity increasing material is dissolved in the fresh wash water in the replenisher tank when a predetermined quantity of the deionized water is supplied so as to electrically connect a pair of electrodes disposed at a predetermined depth of the replenisher tank. A sterilizer is mixed in the fresh wash water to prevent bacterial growth in the replenisher tank. The conductivity increasing material and the sterilizer are prepared as a predetermined dose of mixture necessary and sufficient for the predetermined quantity of deionized water supplied into the replenisher tank.

摘要:
A method for processing silver halide photographic lightsensitive material in which there are used replenishers for water washing and/or stabilization processes in such manner that the concentrations of calcium and magnesium compounds present in the replenishers are not more than 5 mg/l on the basis of elemental calcium and magnesium respectively, and a part or whole of the overflow from the water washing and/or stabilization process is introduced into a process preceding the water washing and/or stabilization processes. This method makes it possible to save water, to diminish the amount of waste liquor and to make effective use of components contained in processing solutions, without impairing any properties of lightsensitive materials to be processed.

In a photographic paper to be attached to the surface of a desired object, a white adhesive layer, a resin layer containing a light reflective material and an emulsion layer on which an image is to formed are laminated, in this order. The photographic paper can be produced by laminating a resin layer containing a light reflective material on a support base so that the peeling strength between the support base and the resin layer is within a range of 10 to 200 gW, and then laminating an emulsion layer on the resin layer. An image is printed on the emulsion layer, and the support base is removed from the resin layer. Then, a white adhesive layer is provided on the exposed surface of the resin layer.
