ABSTRACT:
Imageable articles having dye selective interlayers comprising copolymers of styrene and vinylidene chloride are disclosed. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be prevented from diffusing away from an image receiving layer. Additionally, the selective interlayers allow unoxidized leuco dye to be diffused away from an image receiving layer, thereby increasing print stability. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color density in the final image.
