I'm aware of such stuff, and it's rather expensive indeed,
it's made by 3M. It is 0.5 mm aluminium with a photosensitive
coating, developed with a liquid. It has a glue to stick it 
onto a base material. That glue they use is amazing, 
it's like chewing gum, but even stickier.

Anyway, the transfer of lettering etc is as much a hassle
as is the making of pcb's... And the resulting coating is
not as dark black as I'd like, and it's easily scratched,
so it needs a plastic spray coating or something like that.
It is available in several colours.

(So this must be a different material than described by Stew.)
