摘要：
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.
