That obviously is the very reason why all the other Kodak transparency films later on used essentially the same process as initially developed by Agfa.<br />I am not a chemist, but as I understand it, Agfa's solution was in a way ingeniously simple. The emulsion structure of film at that time was relatively coarse as far as the silver halides are concerned. To prevent color coupler migration, they simply made the resulting color couplers large enough that they could not pass the general structure of the emulsion. With other words, the color couplers got stuck in their respective emulsion layers.LEICA Barnack Berek Bloghttps://www.blogger.com/profile/09055435560407011075noreply@blogger.comtag:blogger.com,1999:blog-1320126156594375642.post-51469586571223011582017-03-10T11:34:29.185-06:002017-03-10T11:34:29.185-06:00Do you have any idea how Agfa finally solved the p...Do you have any idea how Agfa finally solved the problem of color coupler migration to the other emulsion layers? I understand Kodak's solution with the Kodachrome, but that turned out to be somewhat of a hassle since it required for the film to be sent to a processing lab.Anonymousnoreply@blogger.com
