A Post-it note (or Sticky Note) is a piece of paper stationery with a re-adherable strip of adhesive on the back, designed for temporarily attaching notes to documents and other surfaces. Although now available in a wide range of colors, shapes, and sizes, Post-it notes are most commonly a 3-inch (76 mm) square, canary yellow in color. A unique low-tack adhesive allows the notes to be easily attached and removed without leaving residue.
Post-it notes were invented by 3M's Art Fry, using an adhesive developed by a colleague, Spencer Silver. Until the 1990s, when the patent expired, they were produced only in the 3M plant in Cynthiana, Kentucky. Although other companies now produce sticky or repositionable notes, most of the world's Post-it Brand notes are still made in Cynthiana.
The term "Post-it" and the canary yellow color are registered trademarks of 3M. "Sticky Note", likewise, is a trademark of Société Bic. Generic terms for competitors include "repositionable notes" and "repositional notes". To take advantage of the success of the brand, 3M manufactures other products related to the Post-it concept.
In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, was attempting to develop a super-strong adhesive, but instead he accidentally created a "low-tack", reusable, pressure-sensitive adhesive that has been characterized as "a solution without a problem". For five years, Silver promoted his invention within 3M, both informally and through seminars, but without much success. In 1974, a colleague of his, Art Fry, who had attended one of Silver's seminars, came up with the idea of using the adhesive to anchor his bookmark in his hymnbook. Fry then developed the idea by taking advantage of 3M's officially sanctioned "permitted bootlegging" policy. 3M launched the product in stores in 1977 in four cities under the name "Press 'n Peel", but its results were disappointing. A year later, in 1978, 3M issued free samples to residents of Boise, Idaho, and 94 percent of the people who tried them said that they would buy the product. On April 6, 1980, the product debuted in US stores as "Post-It Notes". In 1981, Post-its were launched in Canada and Europe.
In 2003, the company came out with Post-it Brand Super Sticky notes, with a stronger glue that adheres better to vertical and non-smooth surfaces.
Standard Post-it Brand notes have only partial adhesive coating on the back, along one edge. Similar products are used for specialized purposes with full adhesive coating; the US Post Office uses such yellow address labels to forward mail.
The yellow color was chosen by accident; a lab next-door to the Post-it team only had scrap yellow paper, which the team initially used.
Use in art
"The Yellow Stickee Diary of a Mad Secretary", by Rosa Maria Arenas, is the mini graphic journal of an office worker/artist, exhibited July 7 - August 25, 2013, at the Michigan Institute of Contemporary Art (MICA) Gallery in Lansing, Michigan. The 41 drawings displayed are a tiny percentage of the more than 2000 original drawings that constitute the Yellow Stickee Diary Project which Arenas created while working temp jobs from 1994 to 2005. Printed with archival inks on archival paper, the reproductions include "stickee sized" (3" x 5") framed prints and enlargements of the original drawings (which were all done on post-it notes).
In 2012, Turkish artist Ardan Özmenoglu was selected to have a solo exhibition at Bertrand Delacroix Gallery in the art district of Chelsea, Manhattan. The exhibition, titled “E Pluribus Unum” (Latin for “Out of many, one”), opened November 15, 2012 and featured large scale works on Post-it notes.
In 2004, Paola Antonelli, a curator of architecture and design, included Post-it notes in a show entitled "Humble Masterpieces".
Rebecca Murtaugh, a California artist who uses Post-it notes in her artwork, in 2001 created an installation by covering her whole bedroom with $1000 worth of the notes, using the ordinary yellow for objects she saw as having less value and neon colors for more important objects, such as the bed.
In 2000 the 20th anniversary of Post-it notes was celebrated by having artists create artworks on the notes. One such work, by the artist R. B. Kitaj, sold for £640 in an auction, making it the most valuable Post-it note on record.
Use in technology
Analogues of Post-it notes have also been used in technology in the form of desktop notes which are computer applications developed to allow users to put virtual notes on their computer desktop. These computerized versions of Post-it notes include 3M's own "Post-it Brand Software Notes", "Stickies" in Mac OS, "Sticky Notes" in Windows, or other non-free applications like ShixxNOTE. Additionally, some web applications have developed Post-it sort notes for online use.
