Patent number: 8546070Abstract: 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.Type: GrantFiled: October 15, 2012Date of Patent: October 1, 2013Assignee: Eastman Kodak CompanyInventors: Jess B.
