Interesting article/product. Wonder if it could be used as a photoresist? 

It can be used on materials other than cloth:
http://lumi.co/blogs/projects/3790072-perfect-summer-bangle 

and the non-exposed material washes off, so the exposed material is being left behind. The question is: Will it resist an echant?

and... is it any better than existing materials?

Their FAQ says it only works on absorbent natural materials (cotton, silk, rattan, wood, ...) so I doubt it would work on copper.  It is a dye, after all, but it may have other applications.

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.
