  • Patent number: 8546070
    Abstract: A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record can be used to provide color photographic prints. The element also has a non-light sensitive interlayer between the green light and red light sensitive color records. This interlayer comprises a hydrophilic colloid and an acrylic latex polymer having a glass transition temperature (Tg) of less than 0° C. The presence of this acrylic latex polymer in the interlayer reduces the formation of a cyan line defect when the color photographic print is folded or creased, such as in photobooks.

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.
