Modern Relevance of Invisible Ink Messages
As an indication of security, most inks mentioned above were already known by the end of World War I. However, in 1999, the U.S. Central Intelligence Agency successfully requested that a 1940s technical report on invisible ink remained exempt from mandatory declassification, based on the claim that invisible ink was still relevant to national security. The report thus remained classified until 2011.
Former MI-6 agent Richard Tomlinson alleges that Pentel Rolling Writer rollerball pens were extensively used by MI-6 agents to produce secret writing (invisible messages) while on missions.

“And of the other things death is a new office building filled with modern furniture,
A wise thing, but which has no purpose for us.”

“The season developed and matured. Another year’s installment of flowers, leaves, nightingales, thrushes, finches, and such ephemeral creatures, took up their positions where only a year ago others had stood in their place when these were nothing more than germs and inorganic particles. Rays from the sunrise drew forth the buds and stretched them into long stalks, lifted up sap in noiseless streams, opened petals, and sucked out scents in invisible jets and breathings.”
—Thomas Hardy (1840–1928)
“International business may conduct its operations with scraps of paper, but the ink it uses is human blood.”
—Eric Ambler (b. 1909)
“The first of the undecoded messages read: “Popeye sits in thunder,
Unthought of. From that shoebox of an apartment,
From livid curtain’s hue, a tangram emerges: a country.””
—John Ashbery (b. 1927)
