That didn't help much. I'm not into chemestry. I want to know what types of
cleaners are acetate based. And I want to know brand names. I'm asking for
someone who was told she could remove the "PROOF" stamp from the negatives
that they bought from a photographer who is retiring and selling off his
stash of negatives.
I think you mean acetone, not acetate. Acetone is liquid. Acetate is a
You can buy acetone at any paint supply store. It will have the word
"acetone" in big letters on the label.
Or, if you have too much money, you can buy it as "nail polish remover"
at a cosmetics counter.
It is likely the negatives are made of acetate. I suggest you start by
trying some negative/slide cleaner from a good photo shop. These days not
all of them will have it. Next alcohol. Neither of the above should hurt
the negatives and may remove the stamp. Acetone is very aggressive and I
have not tried it on negatives, but I fear it may damage the negative. Try
it on one first if you must.
I was a photographer for 50 years. I've never known - or even heard of - a
photographer stamping his negatives with *anything*...potential damage,
general PITA and most importantly there is absolutely no reason to do so.
Have you actually *seen* the negatives or have you seen positive prints with
the word "proof"? If the latter, the word may be within the print; i.e.,
photographically created and un-removeable. If stamped you don't want to
use *anything* that will dissolve the ink but wet the emulsion at the same
time. Like alcohol (unless totally anhydrous).

Actually no I haven't seen the negs, and the lady I'm asking for is pretty
naive when it comes to photographic terms and process. I don't see why he
would have stamped the negtives either. As for the validity of the acetone
recommencation.....the photographers assistant is the one who offered the
advice. I'd better check this out further.
Acetate may refer to several things:
As one poster referenced it is a short term for cellulose acetate,
which is a plastic. However, in chemistry acetate has a specific
meaning. It is a molecular species with a specific structure. Acetic
acid, (vinegar) is mainly the acetate species with a proton (acid)
attached. In your case, as another poster indicated, you may be
confusing it with acetone. However, it also could be ethyl acetate
which can be a constituent of nail polish remover (sometimes with
acetone added as well).
An acetate group can be attached to different molecules to give it

tinea pedis. I can't rmember the strength, ten percent or so solution in
Most inorganic acetates can be made by mixing vinegar and the alkalai
hydroxide of the metal in question.
Cellulose acetate was a big safety improvement over cellulose nitrate. the
nitrate was highly flammable. Can be a big problem when you nitrate shirt
collar (really!) goes poof when you drop a cigar ash on it. Or when your
nitrate film goes poof in the movie projector.
