| titleOfInvention | Two equivalent type colour couplers containing carbamoyloxy groups at their active positions and their use in photography |
| abstract | 1466728 Azo compounds which are colour couplers for photographic use KONISHIROKU PHOTO INDUSTRY CO Ltd 22 May 1974 [25 May 1973] 22825/74 Heading C4P [Also in Divisions C2 and G2] The invention comprises two-equivalent cyan couplers including the following azo compounds (a) 1 - hydroxy - 4 - [4 - (l<SP>1</SP> - hydroxy - 3<SP>1</SP>,6<SP>1</SP>- disulpho-2<SP>1</SP>-naphthyl azo)anilinocarbonyloxy]- N - n - dodecyl - 2 - naphthoamide di - sodium salt and (b) 1-hydroxy-4-[4-(2<SP>1</SP>-hydroxy-3<SP>1</SP>,6<SP>1</SP>- disulpho - 1 - naphthylazo)anilinocarbonyloxy]- N - [8 - (3<SP>11 </SP>- n - dodecyloxyphenoxy)butyl] - 2- naphthoamide di-sodium salt. Such compounds may be obtained by reacting a 1,4-dihydroxy-2- naphthoamide with p-nitrophenyl isocyanate, reducing the product and coupling with a disulphonaphthol. They may be incorporated into a photographic developer solution or a photosensitive silver halide emulsion layer. |
