Glue

Whales:
I initially doubted it would be the colourant, but given that the MSDS I linked claimed that colourant could be a few % of the final composition I might be wrong.

Found as MSDS for UHU Color Glue Stic, but they are completely troll with the ingredients.

I didn't find Saunders SAU99601 (your link), but this link calls the UHU glue stic "purple" with a different product number, SAU99653:
https://www.usaofficemachines.com/sau99653-uhu-stic-permanent-purple-application-glue-stick-1-41-oz-stick-by-saunders-mfg-co-inc.html

That number brings up this safety sheet:
http://content.oppictures.com/Master_Images/Master_PDF_Files/SAU99653_MSDS.PDF

As expected it is useless, except in addition to phenolphthalein (dye --> clear), it lists polyvinylpyrrolidone ("povidone")(https://en.wikipedia.org/wiki/Polyvinylpyrrolidone), but doesn't give a composition range.

If one clicks on the glue stick link in the Wikipedia article, you get this: https://en.wikipedia.org/wiki/Glue_stick


Edit: Sorry, I took a long time referring to post #14 and didn't see the more recent posts.

The USA Office Machines place apparently has stock (but shipping costs make it worth more than its weight in gold). Hmmm.

Not a success :(

A bit sticky but the test print warped and lifted an edge, and the whole thing came off quite easily.

jpanhalt:
That's research.

Have you tried PVA glue (white or yellow wood glue) or rosin alone?  Polyvinylpyrrolidone is really quite similar to PVA.  Shellac may bond a little to well.  It can be used to attach irregularly shaped objects to the faceplate on a jeweler's lathe, but I have used it on a 3" hobby lathe too.
