PURPOSE:To make possible to rapidly process the title material and to effect the excellent desilverization of the sensitive material by specifying the total processing time of bleach and fix processings of the sensitive material and incorporating a specified compd. in the sensitive material. CONSTITUTION:The total processing time of the bleach and fix processings of the sensitive material is specified to less than 3min and 45sec, and the compd. shown by the formula is incorporated in the sensitive material. In the formula. A is a single bond, hydrogen atom., a cation or its precursor necessary for neutralizing a molecule, B is -S- group, etc., X is alkylene, alkenylene, arylene or cycloalkylene group or a combination thereof, Y is hydrogen atom. or a polar substituting group, R1-R5 are each hydrogen atom., alkyl, alkenyl or aryl group, B1 is oxygen or sulfur atom., (l) and (m) are each 0 or 1, (n) is 1 or 2, and when (n) is 2, A is a single bond. Thus, the rapid and low replenishing processings of the sensitive material make possible, and the desilverization property of the sensitive material is improved. |
