This question would be best answered by an employee of 3M, specifically Spencer Silver...
____________________________________________________
The original adhesive used in Post-it notes was invented in 1968 by Spencer Silver, a 3M researcher. While attempting to design a strong adhesive, he instead developed an adhesive that was very weak. No immediate application was apparent, until 1974 when a colleague, Arthur Fry, conceived of using the adhesive to create bookmarks while contemplating a hymnal in his church choir. Initial prototypes were available in 1977, and by 1980-1981, after a large sampling campaign, the product had been introduced around the world.
