Half esters of isobutylene/maleic anhydride copolymer as attenuators of photographic film development |
| abstract |
A photographic film with a polymeric acid-reacting neutralizing layer comprising a half ester of isobutylene/maleic anhydride copolymer is provided herein. This polymeric acid-reacting neutralizing layer is used to attenuate a photographic film's development process, which is effective under alkali conditions, by lowering the pH of the alkaline processing composition. |
