Color negative film was introduced in 1941-2 with Kodacolor (George
Eastman
House says 1941, Eastman Kodak says 1942 for this film).

Earlier than that. It was patented by Agfa in 1936, and put on the
market in 1937.

Found a few more facts... Agfa introduced their Agfacolor-Neu transparency
film in 1936. Their color negative film didn't appear until 1939 - two
years before Kodacolor.
