I also see records bearing an image of the printing on the sleeve. This
evidently is caused by chemicals in the ink which react with the shellac.
By the way, never write on a record sleeve with a magic marker - you will
see the same thing happen.

What I have not seen (as far as I know) is any record obviously affected by
an acid-laden sleeve. Has anyone else?
