| 摘要 |
<p>() An improvement in the prevention colour-fog and staining in colour-photographic materials is obtained by the inclusion of acylamino substituted hydroquinones derivatives. The compounds can easily be synthesized do not crystalize from their dispersions and are not oxidized to coloured by-products during developments.</p> |
