Do we have any chemists in the group?  

The photographic "fixatives" may very well be, at most, slight tweaks on common coatings.

I have often wondered whether there are any meaningful chemical differences between a pricey gloss or matte "art" varnish and a top quality product made for floors or furniture.  There are very few types of clear coatings, and they have been well understood for years.  My wild guess is that there is not a large enough "art market" to justify wholly distinct formulas and manufacturing, although I would imagine that manufacturers can easily tweak formula runs for special purposes.
