 Essentially, the "Imbibition Agreement" lifted a portion of the "Monopack Agreement's" restrictions on Technicolor (which prevented it from making motion picture products less than 35mm wide) and somewhat related restrictions on Eastman Kodak (which prevented it from experimenting and developing monopack products greater than 16mm wide).Eastmancolor, introduced in 1950, was Kodak's first economical, single-strip 35 mm negative-positive process incorporated into one strip of film.This eventually rendered Three-Strip color photography obsolete, even though, for the first few years of Eastmancolor, Technicolor continued to offer Three-Strip origination combined with dye-transfer printing (150 titles produced in 1953, 100 titles produced in 1954 and 50 titles produced in 1955, the very last year for Three-Strip as camera negative stock).
