摘要： An improved photographic element comprises a support bearing at least one silver halide emulsion layer having associated therewith a hydroquinone compound that functions as a scavenger for oxidized developing agent. The hydroquinone compound has sufficient bulk that it is substantially non-diffusible in the photographic element and has in the two-position thereof an asymmetric tertiary carbamoyl substituent. These scavenger compounds exhibit very high activity, have excellent stability upon long-term storage and do not leave colored residues after processing.

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.
