Yellow couplers having an aryloxy coupling-off group which contains an orthopolarizable functional group. |
摘要 |
<p>Novel yellow dye-forming couplers, and photographic elements, emulsions and processes for developing images utilizing the novel couplers, are disclosed. The novel couplers include (a) an acyl acetanilide in which the acyl group has a monocyclic or multicyclic carbon center attached to the carbonyl moiety, and (b) an aryloxy coupling-off group at the coupling position of the acylacetanilide, the coupling-off group having in the ortho position a polarizable substituent.</p> |
