摘要:
A rinse-processing composition of the present invention comprises a compound represented by R-(OC2H4)n-OH, wherein R is an alkyl group containing 8 to 13 carbon atoms and n is an integer of 10 to 30, but comprises neither aldehyde compounds nor hexamethylenetetramine derivatives, and a processing method and a processing apparatus of the present invention uses such a rinse-processing composition.
摘要:
A method of processing photosensitive material which passes through at least two processing solutions in which the material is rinsed after passing through a first solution and prior to passing through the second solution. The mixture of rinse solution and recovered first solution is returned to the process cycle to replenish the first solution.
摘要:
An aminopolycarboxylic acid compound represented by X 1 represents a hydrogen atom, alkyl group, hydroxyethyl group, alkoxyalkyl group or hydroxyl group, X 2 represents an alkyl group aralkyl group, hydroxyl group, hydroxyalkyl group or alkoxyalkyl group, M 1 , M 2 , M 3 and M 4 each represent a hydrogen atom or cation, and t and u each represent 0. The aminopolycarboxylic acid compound of the present invention can be used as a chelating agent for various metals, which is excellent in the biodegradability and masking effect on metals. The aminopolycarboxylic acid or a heavy metal complex thereof may be used as an additive in photographic materials and processing solutions in which case t and u may be 0-5.
摘要:
A photographic processing composition containing at least one compound represented by formula (I)
wherein R, R 1 and R 2 each represent a hydrogen atom, an alkyl group or an aryl group; and L 1 represents an alkylene group or an arylene group. Also disclosed a processing composition for a silver halide color photographic material containing a metal chelate compound formed from a compound represented by formula (I) and a metal salt selected from salts of Fe(III), Mn(III), Co(III), Rh(II), Rh(III), Au(III), Au(II) and Ce(IV). A method is also disclosed for processing a silver halide photographic material with the processing compositions.

摘要:
Color photographic materials are processed using a final rinse solution containing as essential components: a water-soluble or water-dispersible glycol, and a mixture of two specific surfactants. One surfactant is a nonionic polyethoxylated, nonfluorinated compound, or an anionic non-fluorinated sulfate or sulfonate, and the second surfactant is a nonionic or anionic fluorinated compound. This solution provides processed materials, with or without a magnetic backing layer, that are free of scum or other residues, non-tacky, and resistant to abrasion and fingerprinting. The final rinse solution can be provided in concentrated form, particularly because the glycol is included.
摘要:
A method for processing a black-and-white silver halide photographic light-sensitive material. The method comprises the steps of (1) developing the black-and-white photographic light-sensitive material containing a quaternary onium compound with a developer containing ascorbic acid or a derivative thereof and having a pH value of from 8.0 to 10.0, (2) fixing the light-sensitive material, (3) washing the light-sensitive material by an automatic processor having a multi-step counter flow washing system, and (4) drying the light-sensitive material.
摘要:
A method of processing photographic material comprises developing the photographic material by treatment with a developer (26), and fixing the developed photographic material by treatment with a fixer (32, 38) while reducing the level of silver ions in the fixer (38) by electrolysis. Between the developing and the fixing, the photographic material is treated with an intermediate treatment liquid (44) for a period of time less than the treatment time with the fixer (32, 38). The intermediate treatment liquid (44) contains used fixer (38). The efficiency of fixing is improved without the use of substantially greater liquid volumes and in particular without the use of further quantities of water.
