Matthew,
I use ordyl alpha. There are several manufacturers of such dryfilm
resist. Usually you get it from PCM board house suppliers. Since there
you most likely will have to buy two rolls (all professional laminators
work with two rolls one for the top, the other for the bottom layer)
that might be a bit pricey. Well, I usually still buy two rolls, cause
that material is so versatile I use it up easily and usually also offer
some meters of it to others intersted.
If you search the archives there were other threads. I vaguely remember
that there is an online shop selling sheet material - obviousely at
higher prices...
