    Kodak Archives are located at the Rush Reeves Library / Rochester University.
    I contacted with them many times asking the chemistry of two color red and green inorganic pigments. One researcher told me green was cyanide based but no idea for red.
    I looked their index and found collection of Kodak Research Abstracts 1915 to
    1960s. Next month I will order interlibrary loan from 15 to 22.
    What about 1960s to recent times research abstracts ?

    Thanks ,

    May I ask what you plan to do with the information? Or just for reference?

    Capstaff (in 1914 - 1916) talks about acid dyes, "preferable a salt of a sulfonic acid".
    Not red and green, but "one an orange-red and the other a blue green".

    Q.G.

    I know how he described the colors. Sulfonic acid dyes concept even patented by himself.
    But it is not used for 22 kodachrome but bleach and replace silver with inorganic pigments.
    I wrote about these at older posts.

    Holmsburger ,

    I cant decide to what to do before learning the chemistry.

    Me either.
    Interlibrary loan is not usually free these days...
    It is rather inconcievable that you would ask for pounds of books to be sent across the world with no particular reason in mind, and looking for nothing in particular.

    KA cover a wide range of topics and are not a Betty Crocker Cookbook.
