摘要:
A recycling method for photographic processing waste liquid is disclosed. The photographic processing waste liquid is subjected to evaporative concentration under a reduced pressure of not higher than 700 mmHg and at a temperature of not higher than 90.degree. C. The resulting distillate is used as a solvent for photographic processing agents or as an evaporation compensator for processing tanks of an automatic processing machine.

In an apparatus for processing a light-sensitive silver halide photographic material, there is provided a solid agent replenishing device to store a package in which a solid agent is packed in a moistureproofing manner. The replenishing device releases the solid agent from the package so as directly replenish the solid agents to the processing tank.

摘要:
A method for developing light-sensitive silver halide photographic materials, in a compact automatic developing machine, comprising transporting the light-sensitive silver halide photographic materials to a processing tank which contains a processing solution for processing an exposed light-sensitive silver halide photographic material. The processing tank includes a processing portion, and a receiving portion for receiving a solid processing agent. A solid processing agent is supplied to the receiving portion of the processing tank based on information on the amount of processing of the light-sensitive silver halide photographic materials. The solid processing agent is preferably in the form of tablets which contain all components necessary to process the light-sensitive silver halide photographic material. The processing solution is circulated between the processing portion and the receiving portion at a flow rate of not less than 0.5 times the processing tank volume per minute.
摘要:
An apparatus for processing a light-sensitive silver halide photographic material and which has a solid agent replenisher, is provided with a water producing device to recover water from the air or from used processing solution. The apparatus also is provided with a water replenisher which delivers recovered water to a processing tank to replenish the water in the processing solution contained therein.
摘要:
A method for processing a silver halide color photographic light-sensitive material is disclosed. Fogging caused by the color developer contaminated by heavy metal ions is surpressed by the processing method. The processing method is excellent in the point that stable photographic propertied can be obtained for long while of running. The processing method comprises a step for developing with a color developer an imagewise exposed light-sensitive material which comprises a support and a photographic layer being provided on the support and including at least one silver halide emulsion layer, wherein the photographic layer has a swelling ratio within the range of from 1.5 to 3.5 and the silver halide emulsion layer comprises a silver halide emulsion having a silver chloride content of not less than 90 mole %, and the developing step is performed for a time of not less than 90 seconds with a color developer containing a compound represented by the following Formula (1): ##STR1## wherein R.sub.1 and R.sub.2 are each a hydrogen atom or an alkyl group provided that R.sub.1 and R.sub.2 are not hydrogen atoms at the same time, and R.sub.1 and R.sub.2 may be combined to form a ring.

摘要:
A compact automatic developing machine for silver halide photographic light-sensitive materials with improved operability which makes it easy to reduce the replenishing rate and which offers stable photographic performance, comprises at least one processing tank for containing a processing solution for processing an exposed silver halide photographic light-sensitive material. A solid processing agent is stocked and supplied to the processing tank, information on the amount of processing of the silver halide photographic light-sensitive materials is detected, and the supply of the solid processing agent is controlled according to the detected information on the amount of processing of the silver halide photographic light-sensitive material. The solid processing agent is preferably in the form of tablets which contain all components necessary to process the light-sensitive silver halide photographic material.
摘要:
Disclosed is a processing method for silver halide color photographic light-sensitive material in which a silver halide color photographic light-sensitive material is processed with a processing solution capable of fixation and then a part or all of the overflow from stabilizer is allowed to enter in the processing solution capable of fixing wherein said silver halide color photographic light-sensitive material contains a coupler represented by Formula 2eq-1 and said stabilizer contains substantially no formaldehyde but contains a compound represented by Formula I or Formula II: ##STR1##R.sub.1 --O--(R.sub.2 --O).sub.m --X.sub.1 (Formula I) ##STR2## The total amount of silver coated in said silver halide color photographic light-sensitive material is not less than 3 g and not more than 10 g per m.sup.2 of light-sensitive material;said silver halide color photographic light-sensitive material contains a compound represented by the following formulae B-1 through B-3, ##STR3## the above constituents are defined in the specification. The processing method for silver halide color photographic light-sensitive material according to this invention offers good dye image preservability and improved staining in the unexposed portion and which permits waste liquid reduction and is hence excellent from the socio-environment viewpoint.
