    RC Paper Longevity

    I tried a search but it turned up nothing. Having recently returned to B&W film work, I recalled that a number of years ago there were issues with the longevity of RC papers. Is this still a problem, or have these been resolved? Thanks in advance.
    WYSIWYG - At least that's my goal.

    I don't know how long a time you are thinking of but I have some RC 11X14 that is over 6 yo and still prints nice. Agfa and Luminos

    No one knows for certain, but modern RC papers seem quite log-lived.

    Still, if you want to be assured of the longevity of your prints, fibre papers are not that difficult to use, have a beautiful tonality, and will give you the best that silver photography can do.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    It depends on manufacturer.

    The chemistry used for most stabilization is expensive, and so to cut costs, the amount is reduced. Other companies don't have big research budgets so they do the best they can.

    Only Ilford, Kentmere and Fuji papers meet my criteria. Kodak would if they made them.

    Others, maybe? IDK. I rarely test them and have no recent experience.

    Sometimes RC is worse than FB and sometimes FB is worse than RC. It depends. You cannot make a generalization that works for a specific paper.

    I guess i read this wrong (shocking) I was thinking about keeping unexposed paper not in terms of the archival quality of RC paper!! Now about the archival quality of RC paper-----I don't know pooh about that. I have read 7-10 years max and I have also read properly process RC can last 100+years who really know---I like the look of fiber better----sorry

    I have hundreds of prints on Kodak RC paper from 1972 to 1975 that are as good as ever.

    I just used Kodak RC paper made in the early 70's and they work perfectly still. i'm getting bright whites and deep blacks.

    You can read the OP either way. And, either way, my answer is valid.

    The first generation of PE/RC papers suffered from yellowing (and brittleness?) of the polyethylene foils over time. This was believed to be caused by the titaniumdioxide, which was added to the plastic as white pigment, catalysing destructive reactions under the influence of oxygen and light .
    Meanwhile antioxidative agents and peroxide scavengers are added to the plastic, which are believed to stop that problem. Accelarated-aging test make the industry consider a longevity of these foils of many decades.

    However, I wonder about the outcome or consideration of the aging tests of the first generation RC papers…

    Dear All,

    Our on-going longevity tests of RC base products show better stability than we ever thought at the outset.
    Quality RC ( monochrome ) products from the major manufacturers should certainly extend to the 50+ year mark with ease, the issue as correctly noted above is on the structure and permanence of the substrate and its interaction with the coating. As always, for true archival permanence use fibre base, and correct storage disciplines.
