Photographic recording material employing a nondiffusible magenta dye-releasing compound or precursor thereof. |
摘要 |
<p>A photographic recording material is described which employs a novel nondiffusible compound capable of releasing at least one diffusible magenta dye moiety said compound having the formula: <CHEM> wherein: (a) X represents the atoms necessary to complete a 5- or 6-membered heterocyclic ring; (b) Y represents the atoms necessary to complete a 5- or 6-membered heterocyclic fused ring; (c) CAR represents a ballasted carrier moiety capable of releasing the diffusible magenta dye moiety as a function of development of a silver halide emulsion layer under alkaline conditions; (d) R represents a hydroxy group, a salt thereof, or a hydrolyzable precursor thereof, or CAR which is linked to the dye moiety through an oxygen atom thereon; and (e) n is 0, 1 or 2, with the proviso that when n is 0, then R is CAR which is linked to the dye moiety through an oxygen atom thereon.</p> |
