(54) Image carrying media


(57) An optical barrier layer for use in reflection type image carrying media of the type wherein a thin transparent image receiving layer includes an image which is viewed through one side of the image receiving layer with ambient light that is reflected from a light scattering layer located on the other side of the image-receiving layer. The optical barrier layer is a thin, transparent layer located between the image receiving layer and the light scattering layer and operates to minimize nonlinear density effects of multiple internal reflections.
