Process for forming black dye images |
| abstract |
A process for forming a dye image is disclosed which comprises processing an image-wise exposed silver halide photographic emulsion with an aromatic primary amine color developing agent in the presence of bis pyrazolines obtained by reacting 3-acylamino-5-pyrazolones with para-hydroxybenzaldehydes having at least one of the ortho positions to the hydroxy group substituted with a member selected from halogen, alkyl, aryl, amino or amido groups. The invention includes the present dye forming coupler alone and combined with the silver halide emulsion layer. |
