Melenex subbed film base

Esters based on cellulosis can be softened by solvents. By this approach solvent containing subbing layers can be made which form an intermediate between emulsion and base.

PET, which is an ester too, though is hard to dissolve. Thus other approches had to be looked for. Making the PET reaktive is one way to do.
