- wherein X.sub.2 represents a hydroxyl group, a halogen atom, an amino group or a --COOM.sup.3 group, A represents an alkylene group, M.sup.3 represents a hydrogen atom, an ammonium group, an alkali metal atom or an organic ammonium group, and
- said flexible container is composed of a multilayer film comprising at least one layer of a polyolefin resin or a polyethylene-vinyl acetate copolymer resin, and at least one layer of a resin selected from the group consisting of:
- A. ethylene-vinyl alcohol copolymer resins,
- B. polyamide resins,
- C. acrylonitrile resin,
- D. polyethylene terephthalate resin,
- E. polyhalogenated vinylidene resin,
- F. polyhalogenated vinyl resin,
- G. polyethylene resin deposited with ceramic, and
- H. polyethylene terephthalate resin deposited with ceramic.
A photographic processing chemicals kit comprising a processing agent contained in a sealed flexible container, wherein said container is composed of one multilayer film comprising at least one layer of a resin selected from a polyolefin resin or a polyethylene-vinyl acetate copolymer resin, and at least one layer of a resin selected from the group consisting of:
- A. ethylene-vinyl alcohol copolymer resin,
- B. polyamide resin,
- C. acrylonitrile resin,
- D. polyethylene terephthalate resin,
- E. polyhalogenated vinylidene resin,
- F. polyhalogenated vinyl resin, and
- G. polyethylene resin deposited with ceramic, and
- H. polyethylene terephthalate resin deposited with ceramic;
- polyethylene or polyethylene terephthalate film deposited with ceramic;
- wherein the water vapor transmission rate of the multilayer film is not more than 20 g/m.sup.2.day, and the oxygen transmittance of the multilayer film is not more than 5 ml/m.sup.2.day.atm, and
- said processing agent is a bleaching agent comprising at least one compound represented by Formula B:
- Formula B
- X.sub.2 --A--COOM.sup.3
- wherein X.sub.2 represents a hydroxyl group, a halogen atom, an amino group or a --COOM.sup.3 group, A represents an alkylene group, M.sup.3 represents a hydrogen atom, an ammonium group, an alkali metal atom or an organic ammonium group.
