PURPOSE:To obtain the good shelf-life and the safety of the titled solution at the time of transporting said solution by incorporating a specified component in the titled solution, and by storing the titled solution in a case composed of a plastic wrapping material comprising a composite film. CONSTITUTION:The titled solution contains 0.03-0.40mol./l sulfite and has pH (25 deg.C) of 3.9-6.5, and is stored in the case composed of the plastic wrapping material comprising at least one sheet of the composite film. The wrapping material has the excellent gas tightness, and prevents the deterioration in quality of the titled solution, and also does not generate a defect such as a pinhole and a crack at the time of transporting. Thus, the titled solution with a commodity form is composed of an one liquid fixing solution capable of easing a mixing and compounding, and does not generate the injury, etc., at the time of transporting, and can be stored for a long period. |
