Scotch Tape  is a  brand name  used for certain  pressure sensitive tapes  manufactured by  3M  as part of the company's Scotch brand. The precursor to the current tapes was developed in the 1930s in  Minneapolis, Minnesota  by  Richard Drew  to seal a then-new transparent material known as  cellophane . [1] Although it is a   trademarked   brand name,   Scotch tape   is commonly used in the   United States ,   Canada ,   Italy   and elsewhere as a   generic term   for transparent adhesive tape. (The Australian, Irish, New Zealand, and UK equivalent of   Scotch tape   is   Sellotape .) The Scotch brand includes many different constructions (backings, adhesives, etc.) and colors of tape.
The use of the term  Scotch in the name was  pejorative in the 1920s and 1930s: in 1925, a customer complained that 3M was manufacturing its masking tape too cheaply, and told company engineer Richard Drew to "take this tape back to your stingy Scotch bosses and tell them to put more adhesive on it." [2]
Scotty McTape, a  kilt-wearing  cartoon boy, was the brand's  mascot for two decades, first appearing in 1944. [3] The familiar  tartan design, a take on the well-known  Wallace tartan, was introduced in 1945. [3]
The Scotch brand and Scotch Tape are registered trademarks of 3M. Besides using  Scotch as a prefix in its brand names ( ScotchgardScotchlite, and  Scotch-Brite), the company also used the Scotch name for its (mainly professional) audiovisual magnetic tape products, until the early 1990s when the tapes were branded solely with the 3M logo. [4] In 1996, 3M exited the magnetic tape business, selling its assets to  Quantegy (which is a spin-off of  Ampex).In 1953, Soviet scientists showed that  triboluminescence caused by peeling a roll of an unidentified Scotch brand tape in a  vacuum can produce  X-rays. [5] In 2008, American scientists performed an experiment that showed the rays can be strong enough to leave an X-ray image of a finger on photographic paper. [6]
