| titleOfInvention | Photographic reversal process using a color developing agent in the black-and-white developer |
| abstract | A photographic reversal process for the production of positive photographic images by imagewise exposure of the photosensitive material containing at least one silver halide emulsion layer, black-and-white first development of the material, chemical fogging, color development and bleaching, fixing, washing or stabilizing and drying, in which the material is transferred from the first development to the color development without any intermediate steps, such as intermediate washing or diffuse second exposure, the first development bath exclusively contains one or more N,N-dialkyl-p-phenylenediamine derivatives as developer and a tin(II) complex compound and is adjusted to a pH value of <8 and the color development bath likewise exclusively contains one or more N,N-dialkyl-p-phenylenediamine derivatives as developer and is adjusted to a pH value >10, requires considerably less time than the conventional process but produces equivalent results. |
