Positive-working immobile photographic azo compounds |
| abstract |
Photographic elements, processes for forming images in photographic elements and new compounds are disclosed. Generally, the invention relates to immobile compounds which can be used to provide positive images from negative recording-developing photographic materials such as negative silver halide emulsions. The compounds contain a photographically useful group such as a dye or dye precursor and are capable of releasing said photographically useful group under alkaline conditions, and are also capable of reaction with an oxidized silver halide developing agent before substantial release of said photographically useful group occurs, to provide a reaction product having a substantially lower rate of release of said photographically useful group. In specific embodiments, the compounds of this invention contain an electrophilic cleavage group located in the linkage between a ballast group and a photographically useful moiety wherein said electrophilic cleavage group is a carbamic acid derivative. |
