Subject: Dye stability in C41 B&W films
Does anyone know of anything published on dye stability in the various C41-process black & white films that have been on the market in the past fifteen years or so? Ilford has had two (XP1 and XP2); last year Kodak started distributing its T400CN; and now I see Konica has a version packed in throwaway cameras. I don't know anything about the Konica film but the Ilford and Kodak films differ quite noticeably: Kodak has a light mask to make printing on colour machines easier, while the Ilford film is a (more or less) clear film. All three must use a dye and it seems at least possible that they all use different dyes. I wonder whether these dyes have approximately the same life expectancy as other colour dyes, or indeed if they've been tested.
