Claims
- 1. A method for reducing treatment of a silver halide photographic light-sensitive element for a photomechanical process wherein said photographic light-sensitive element comprises a support, at least one photosensitive silver halide emulsion layer thereon, and at least one light-insensitive upper layer on the emulsion layer, wherein said light-insensitive upper layer comprises a hydrophillic colloid and at least one of the light-insensitive upper layers contains a compound having an electric charge and is substantially insoluble in water but soluble in a water-miscible organic solvent, wherein said compound is employed in am amount sufficient for increasing adaptability to a reducing treatment and wherein said compound is a polymer containing at least 5 mol % of a unit represented by formula (I): ##STR10## wherein R represents an aliphatic hydrocarbon group having from 4 to 22 carbon atoms; m.sub.1 and m.sub.2 represent each 0 or 1; B represents --O-- or --NH--; A represents an aliphatic divalent group having from 1 to 50 carbon atoms; and X represents a functional group having an electric charge, said method comprising bringing a silver image, formed on the light-sensitive element by exposure and development, into contact with a reducer through said light-insensitive upper layer containing said compound.
- 2. The method as claimed in claim 1, wherein said compound has a solubility in water at 25.degree. C. of not more than 0.01% by weight, and a solubility in a water-miscible organic solvent at 25.degree. C. of at least 1% by weight.
- 3. The method as claimed in claim 1, wherein said polymer is a copolymer containing from about 10 to 60 mol % of the unit represented by formula (I).
- 4. The method as claimed in claim 1, wherein said compound is used in an amount of from about 2 to 150% by weight based on the weight of the hydrophillic colloid in the light-insensitive upper layer.
- 5. The method as claimed in claim 1, wherein said compound is used in an amount of from about 10 to 60% by weight based on the weight of the hydrophillic colloid in the light-insensitive upper layer.
- 6. The method as claimed in claim 1, wherein said water-miscible organic solvent is selected from the group consisting of lower alcohols, acetone, dimethylformamide, dimethyl sulfoxide, n-butanol, water-soluble ketones and lower fatty acid esters.
- 7. The method as claimed in claim 1, wherein said compound having an electric charge is selected from the compounds which contain an anionic charge, a cationic charge and an amphoteric charge.
