| titleOfInvention | Radiographic material having antispot protection and improved speed to Dmin ratio |
| abstract | The present invention relates to a process for manufacturing a silver halidenphotographic material comprising the step of adding to a silver halide emulsion anpolyamine-polycarboxyl derivative and an aryl compound having at least two hydroxylngroups and at least one additional substituent represented by a sulfonicngroup, an hydroxyl group, a carboxy group or a hydroxymethyl group. The use ofnsuch a combination as antispotting agent to prevent metal contamination and to increasenthe speed to Dmin ratio of a silver halide photographic emulsion and a silvernhalide element comprising such an aryl compound is also claimed. |
