CONSTANT RETENTION METHOD FOR DEVELOPING ACTIVITY OF DEVELOPING SOLUTION

机译:开发溶液的活性的常数保持方法

摘要

PURPOSE:To retain the developing activity of a developing solution always at a constant level, by replenishing a developing solution fatigued with development of a positive type presensitized plate by 2 series system. CONSTITUTION:A photosensitive layer containing an o-quinonediazide compound is provided on an aluminum base to form a positive type presensitized plate, and an alkaline developing solution for this plate is replenished with first and second replenishing solutions stronger in alkalinity than this, and the first solution is added each time the photosensitive material (presensitized plate) is processed, and the second solution is added continuously (or intermittently) in a constant rate to retain the activity of the developing solution. The above developing is processed preferably in an automatic developing machine, and it is desirable that the length of the photosensitive material in the running direction is measured to set the amount of first replenishing solution to that of a predetermined proportion to the length, and this amount of the solution is added to the developing solution.
