In a word, no:

Q. Q. Is anything written on the back of the Declaration of Independence?

A. Yes, there is writing on the back of the original, signed Declaration of Independence. But it is not invisible, nor does it include a map, as the Disney feature film, National Treasure, suggests. The writing on the back reads "Original Declaration of Independence, dated 4th July 1776," and it appears on the bottom of the document, upside down. To learn more, read the article, The Flip Side of History. Please note that the back of the Declaration of Independence is not on display in the Rotunda for the Charters of Freedom.
