The sticky notes were at the beginning of canary yellow, by now, since the phase out of the basic patents, they come in many different colors and shapes from multiple vendors. Stickers are a popular promotional gift . They have now become a ubiquitous office tool developed. Special features are the insoluble adhesive bead of adhesive tape. They allow you the piece of paper several times to stick to different surfaces without leaving any residue with a screwdriver.

In 1968, employed Spencer Silver on the Minnesota Mining and Manufacturing Company (3M) to develop a new super glue, which is stronger than all the known adhesives should be. The result of his work was only a sticky mass, which was applied to surfaces at all, however, was again just as easily replace. The only product that was developed into a kind of whiteboard , which should get along without pins. The board was coated with the adhesive so that the list could be removed more easily and hinkleben. As this board sold poorly, it was taken off the market and the invention of Spencer Silver was forgotten.

Years later, in 1974, angered Art Fry , a member of a church choir and a colleague, Spencer Silver, the fact that he’s bookmarks fell out while standing constantly in the music magazines. He remembered the invention of his colleagues and took a sample of the adhesive from the laboratory . He wore it on slips of paper and tested his invention on the very next Sunday in church. And indeed their bookmarks adhered reliable, but were nevertheless easily solved without the sheet music to destroy. The post-its were invented.

The original Post-it is canary yellow and has a size of 76 × 76 mm. There are now more than 400 product types from different manufacturers. In Germany about 4.5 million units per year (about 100 pages each) are sold (as of 04/2005). The U.S. magazine “Fortune” told the Post-it to one of the most important inventions of the 20th Century – along with the refrigerator , the Boeing 707 and the compact disc .
