Abstract
Excessive image density produced during or after processing by dye diffusing from the image generating unit into the dye image-receiving layer of an integral color transfer assemblage is controlled by incorporating into the assemblage a scavenger layer capable of immobilizing byproducts of processing reactions which may affect image quality in the image-receiving layer.
