Imageable articles having dye selective interlayers |
| abstract |
The use of copolymers of vinylidene chloride and vinyl pyrrolidone as selective diffusion media in dye-diffusive photothermographic imaging constructions is disclosed. Unoxidized phenolic leuco dye molecules diffuse into a film of these copolyers but do not readily diffuse out. In contrast, their oxidized dye forms, which are quinoidal in nature, readily diffuse through these interlayers resulting in improved image stability and color separation. |
