Abstract: The present invention relates to a method for processing a silver halide photographic light-sensitive material having at least one silver halide emulsion layer containing silver iodide with a processing solution having fixing ability after developing the light-sensitive material. The object of the present invention is to speed up the fixing process in the foregoing method and to reduce the amount of waste liquor from the fixing process. The present invention is characterized in that the processing with the processing solution having fixing ability is performed while the processing solution is brought into contact with an anion-exchange resin and that 20 to 2,000 l of the processing solution per liter of the anion-exchange resin is brought into contact with the resin.

Abstract: The present invention relates to a method for bleaching a silver halide photographic light-sensitive material having at least one silver halide emulsion layer containing silver iodobromide after color-developing it. The object of the present invention is to speed up the bleaching treatment in the aforesaid method and to reduce the amount of waste liquor from the bleaching treatment. The present invention is characterized in that the bleaching is performed in the presence of a bleaching accelerator and that it is carried out while a bleaching solution is brought into contact with an anion-exchange resin.

Abstract: Novel disubstituted dichlorosilane compounds which have two different specified substituents and are necessary as monomers for preparing special silicone resin are provided and a method for producing same without accompaniment of by-product production is also provided.

Abstract: In the method of producing 3-chloropropyltrichlorosilane by the addition reaction of trichlorosilane to allyl chloride, [Pt(PPh.sub.3).sub.2 Cl.sub.2 ] is used as the catalyst for the reaction.Side reactions are suppressed to give a high yield of the product.

Abstract: Substituted phenethyldichlorosilanes having a longer chain alkyl group and diphenethyldichlorosilane which are useful as compounds for improving heat-resisting property and other properties of silicone-oils, -rubbers and -varnishes which are used as electric insulating materials, lubricating oils, water-repelling agents, paintings, releasing agents, etc. are provided. A method for producing these compounds with a high yield without producing by-products is also provided.

Abstract: A process of selectively separating a developing agent and/or a color development accelerator such as benzyl alcohol, etc., from photographic processing solutions containing these materials by bringing the processing solutions into contact with a copolymer selected from the group consisting of a styrenedivinylbenzene copolymer and a methacrylic acid monoestermethacrylic acid polyester copolymer. The developing agent thus adsorbed on the copolymer can be recovered therefrom by treating the copolymer with, e.g., diluted sulfuric acid.
