COLOR PHOTOGRAPHIC MULTI-LAYER MATERIAL |
| abstract |
Li polyphosphate (I) is used in the blue-sensitive AgX (X = halogen) emulsion of a colour photographic material having a red-sensitive (RS) AgX emulsion contg. an immobile. The process is quick and economical. Organic hydrazine deriv. and hydrazine content can be reduced quantitatively to 0.5 (0.01) ppm. Purified waste waters contain 100-200 ppm organic C and can be charged directly to a clarifying plant. |
