Abstract (en)
[origin: WO9325936A2] Copolymers of acrylonitrile and vinylidene chloride are used as selective diffusion interlayers in dye-diffusive photothermographic imaging constructions. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be diffused from an emulsion layer into an image-receiving layers, but have insufficient permeability to the unoxidized leuco dye precursor. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color separation in the final image.
