Do you think that this polymer stuff would imbibe dyes? Would it stick to completely raw (unsubbed) melinex?

The reason I ask is, if you could coat a layer of this polymer, and have it not lift off of unsubbed melinex, you could then coat a gelatin emulsion for subsequent sensitization and etching using the carbon method. However, it should not be able to imbibe the acid dyes used in dye-transfer processes or else you can't really get clean & clear highlights.

PhotoFormulary has a subbed melinex which is awesome, but I understand it's a somewhat limited supply and who doesn't like an alternative?

Just a thought!
