Method of processing exposed photographic silver dye bleach materials comprising heating after processing liquid application
First Claim
1. A method of processing exposed photographic silver dye bleach materials using the process stages (1) development, (2) dye bleach, (3) silver bleach, (4) fixing and (5) washing, it being possible to combine process stage (3) with process stage (2), or with process stages (2) and (4) into one process stage, which comprises, for the process stages (1) and (2) or the process stages (1) and also (2) and (3) combined or the process stages (1) and also (2) and (3) and (4) combined, applying to the uppermost layer of the material an amount of corresponding processing liquid which is equivalent to not more than the swelling volume of the material, subjecting the material to a heat treatment after each treatment with processing liquid, and, if appropriate, washing and drying the material.

Abstract
The processing of exposed silver dye bleach materials by applying, to the uppermost layer of the material, an amount of processing liquid which corresponds to not more than the swelling volume of the material, followed by a heat treatment.
The process is particularly suitable for the production of positive colored images, especially in automatic copying or photographing machines.
