Morphology

backed = back (transparent) = back + ed

The photographic sense is a technical application but is directly formed from 'back' + '-ed' meaning 'coated on the back side'.

Etymology

Backed comes from the same old root bæc, meaning 'back' or 'rear', and grew to mean 'having a backing', a layer or support on the rear side of something. So a 'backed' film is one that has a special layer on its back to stop light or give support.
