do you mean on polyimide kapton copper clad laminate??
you can get it on ebay ...
Actually thats not a bad idea ....
then run through a laser printer a few times ..... then etch ....
Heck ....
Spendy stuff though ..... but then agin .. its cheeaper than 200$ for a 3 board run ...

Subject: [Homebrew_PCBs] New PCB etching method proposal
I just had an idea of a better PCB generation system. It is still in the
works, but may be a great solution.
There is the photo-resist method that needs darkness.
There is the Toner Transfer System that I use a lot. But I find that I
am always touching up traces, especially the fine ones.
One person figured if they can print directly to the PCB using a laser
jet, but the stiff board would not go through the rollers.
What if I can come up with a flexible material that can be printed to
directly a positive image and then etch? It would be able to go through
laser printers without a problem.
I am building up some samples to test, but would this list be interested
in such a product?
Oh, to stiffen up, just add a piece of fiberglass to the back. Which I
can make as well. Would you be interested in this method? How much would
one be willing to pay for the materials for a 2"x2" size of board -
granted a larger one would be possible as well. In fact, using a legal
size copier would allow one to print up a 11" x 17" circuit board.
