    Crone:C - Formula?

    Hi All,

    I have used Crone:C additive in the past as a speed booster when developing film using D76. I am really curious to know what the formula of Crone:C is - does anybody know?

    AFAIK, the exact formula was never released but it appeared to be a solution of phenidone in isopropyl alcohol.

    The formula for Crone:C is owned and controled by a company called Brandess Kalt, which is a Photographic Distributor in Illinois. We have bottled that product under license for them for 20+- years. You will find it in our catalog/website under intensifiers.

    CBG;
    Sorry it is under "additives" on the web site. Still called Crone-C.
