I am certain that it will NOT work as an etching resist. However, Inko did
make a photo sensitive stencil material. It was a colloidal (?) liquid
that was sensitized with dichromate. IIRC FeCl etchant destroyed it. I
know that acetone and/or chlorine bleach were used to reclaim the screen,
so one had to use a synthetic screen (real silk doesn't last very long in
straight Clorox!)
If your silkscreen technique is good you can use it to make a stencil, then
screen the image onto your boards to make a run. Don't think you'll get
very good resolution compared to direct photo resist.
