Abstract
The invention relates to a photographic element comprising at least one absorber dye and at least one sensitizing dye wherein the peak sensitivity of said absorber dye and said sensitizing dye are similar. This provides improved perceptual red detail in regions of high red density in the negative image.
Claims3
A color photographic paper element comprising, in a red sensitized layer, at least one absorber dye comprising ##STR21## and at least one sensitizing dye comprising ##STR22## wherein the peak sensitivity of said absorber dye and said sensitizing dye overlap for greater than 90% of the spectral envelope.
