 In the field of motion pictures, the many-layered type of color film normally called an "integral tripack" in broader contexts has long been known by the less tongue-twisting term "monopack".For many years, Monopack (capitalized) was a proprietary product of Technicolor Corp, whereas monopack (not capitalized) generically referred to any of several single-strip color film products, including various Eastman Kodak products.It appeared that Technicolor made no attempt to register Monopack as a trademark with the US Patent and Trademark Office, although it asserted that term as if it were a registered trademark, and it had the force of a legal agreement between it and Eastman Kodak to back up that assertion.
