PURPOSE:To rapidly desilverize the title film by processing the disk shape-film with a specified bleach-fix bath, while rotating the film with a prescribed rotating speed. CONSTITUTION:The disk-shape film is color-developed, and then is processed with the bleach-fix bath which does not substantially contain a silver ion and an iodine ion, and contains a bleach-accelerating agent shown by formulas I and/or II, while rotating the film at a speed of 10-1,000r.p.m. In formulas I and II, Q is an atomic group necessary for forming a heterocyclic ring, R<0> is an aliphatic or aryl group, etc., R<2> is hydrogen atom or a group shown by formula III, Q<1> is the same meaning to the group Q. The bleach accelerating agent shown by formulas I and/or II is composed of a compd. etc., shown by formula IV. And, when the rotating speed of the disk film is slower than the prescribed speed, the desilverization of the film is insufficient, while when the speed of the film is faster than the prescribed speed, the deterioration of the bleach-fix bath is accelerated. So that, the both cases mentioned above are not preferable. |
