Color-forming carboxamidonaphthalene dye precursor and carboximide dye in photographic material and process |
摘要 |
A new color-forming 4-(4'-secondary or tertiary-amino)anilino-1-carboxamidonaphthalene dye precursor in a photographic material and process enables formation of a dye image by means of cross-oxidation without the need for a coupling reaction. The color-forming 4-(4'-secondary or tertiary-amino)anilino-1-carboxamidonaphthalene dye precursor is useful in a photographic silver halide material for producing (i) a dye image, or (ii) a dye image and silver image. The exposed photographic material is processed to produce (a) a positive dye image, (b) a negative dye and negative silver image, (c) a negative dye image or (d) a positive dye image and a positive silver image. New naphthoquinoneimide dyes are also described.
