Each of the three layers in the proposed film would be sensitive to one of the three primary colors, and each of the three layers would have substances (called "color couplers") embedded in them that would form a dye of the required color when combined with the by-products of the developing silver image.When the silver images are bleached away, the three-color dye image would remain.Copies of the film for sale to the public were also produced using Kodachrome. These had several disadvantages because they used a réseau filter made from discrete color elements that were visible upon enlargement.
By timing how long it took for an image to form in the top layer, but not yet in the next layer beneath that one, they began to solve the problem that Fischer could not.Because of the growth and popularity of alternative photographic materials, its complex processing requirements, and the widespread transition to digital photography, Kodachrome lost its market share, its manufacturing was discontinued in 2009 and its processing ended in December 2010.After announcing the return of Ektachrome at the beginning of 2017, Eastman Kodak CMO Steven Overman told The Kodakery podcast, "we are investigating Kodachrome, looking at what it would take to bring that back.".The only part left of Fischer's original problem with a multi-layer emulsion were the wandering sensitizing dyes.In 1929 money ran out, and Mees decided to help them once more.
