PURPOSE:To make it possible to rapidly process the title material, and to improve the desilverization of a sensitive material by specifying the black colloidal silver content and the degree of swelling of the sensitive material, respectively. CONSTITUTION:The degree of swelling of the sensitive material has largely effect on the desilverization. Namely, the sensitive material is processed by image-likely exposing the sensitive material mounted at least two layers of each of a blue photosensitive layer, a green photosensitive layer, and a red photosensitive layer on a supporting body, and then subjecting the exposed sensitive material on a color-development, followed by processing it with a processing bath having fixing ability immediately after a bleaching processing, and the total processing time of the bleaching and a fixing processings is specified within 3min and 45sec. So that, the black colloidal silver content of the sensitive material is controlled to <=0.10g/m<2> converting to a metallic silver, and the degree of swelling of the sensitive material is controlled to 1.5 to 4.0. The black colloidal silver is composed of an ordinally colloidal silver having a particle size of >=20mum, and especially, is incorporated in a nonphotosensitive layer near to the supporting body. |
