Photographic elements comprising 2-phenylcarbomoyl-1-naphthol image-modifying couplers yielding dyes resistant to crystallization and reduction |
摘要 |
<p>Photographic elements comprising certain 2-phenylcarbamoyl-1-naphthol image-modifying couplers exhibit proper hue, a resistance to dye crystallization, and a resistance to leuco cyan dye formation. Such couplers can be utilized for their image-modifying effect and can contribute substantially to the overall dye density of an image.</p> |
