Abstract
The invention is directed to a photographic material, comprising a photographic support and color sensitive recording layers on top of said support, said recording layers being separated from each other by interlayers, wherein the interlayers are characterized by the interlayer design parameter {[SC]*d2} (wherein [SC] is the concentration scavenger moieties bound to the water soluble polymer applied in the interlayer per gram total interlayer polymer and the dry thickness of the interlayer) having a value larger than 2.0*10−15 mmol m2/g and a maximum concentration [SC] of 0.5 mmol/g.
