David, Louis,

Thanks for sharing your experience and the pointer. I checked out their 
website. There's no info what material this is. Any idea? Polyurethane? 
Acrylic? 

Today I got a sample from a local colleague of "Eternacryl Inkjet 
Lamination Matte". This is obviously an acrylic medium, I suspect 
identical to the paint medium I can get at my local art shop. I just 
applied it on a smaple and now wait for it to dry. I used a foam brush, 
I guess that was not a good idea. But I have an airbrush lying around, 
so spraying should not a problem.
