摘要:
A color photographic material is described containing a compound of formula (I) wherein, if n=1, R1 is, inter alia, a radical of formula (II), and, if n=2, R1 is unsubstituted or C1–C4alkyl- or hydroxy-substituted phenylene or naphthylene; or —R12—X—R13—, and other residues are as defined in claim 1. The compound of formula (I) is effective as scavenger of the oxidized form of the developer (Dox scavenger), especially when contained in an interlayer between light sensitive layers. Selected compounds of this class can also be used as additives, for example as dye stabilizer, in color photographic materials, or as an antioxidant for organic materials.
