Photographic elements containing development accelerator release compounds |
摘要 |
Certain development inhibitor releasing compounds when incorporated in a photographic element at low levels provide development acceleration. The compounds release silver halide binding groups that are substituted with a group containing an ether oxygen atom and/or an imino nitrogen atom. They are especially useful in high speed color photographic materials.
