Abstract
A cover sheet for an integral imaging receiver element comprises a support, a neutralizing layer, at least one timing layer and an alkali permeable hydrophilic layer. The cover sheet may also contain a second alkali permeable layer coated over the alkali permeable hydrophilic layer to promote adhesion of the cover sheet to the other components of the film unit. The photographic film units containing the cover sheets are substantially free from dark spot imperfections and are resistant to delamination of the unit.
