Hi John
Thanks!
Unfortunately I don't buy anything that has a Koda in its name.
New55 is not marketing this product primarily to replace develop and fix methods...
Ken
I am interested in seeing if this new product has succeeded where others have failed.
best of luck !

The problem with monobaths is that they just don't work very well.
John, ID-11 wouldn't work very well. A monobath needs a very active developer composition. They are therefore most commonly based on the Phenidone-hydroquinone combination, in relatively high concentrations compared with the standard working solutions of Phenidone-hydroquinone developers. This is likely one of the reasons the "scratch" formula uses HC-110. If one hates Kodak for some reason, a possible replacement for HC-110 could be Ilford's Ilfotec HC. The posted scratch formula looks rather crude to me. My guess is the New55 commercial product would be a better option.
Regarding scratch mixing of monobaths, they often use a sodium hydroxide alkali. Take proper precautions regarding the handling and mixing of hydroxides. The same can be said for introducing things like household ammonia solutions into your darkroom. Please be careful.
Do you know what the "sludge" is composed of? Can it be mitigated after formation?
Ken
the concept is always intriguing. Back in the 60s the local camera store had a tiny clear plastic film Tank from Japan. you would stic in the entire 20 exposure cassette and add the little bottle of monobath and wian and rewind the film for some number of minutes, then take the film out or the now ruined cassette, wash it and hang it up to dry. Item was promoted as a way to check that your camera was still working when you were travelling. using a 20 exposure roll allowed for room for the solution to get at the film.
Never saw them sell one, and so I don't know if it worked.
The new stuff advertised here is intriguing for sure, although the shipping restrictions make it useless for so many people. It is not rated as per capacity, or shelf life on the order page. if it is used one shot it would be quite expensive.
The first use of a monobath was reported in the BJ of 1859. Since then numerous formulas have been proposed. Some have even become commercial products. None of them were able to satisfactorily overcome several severe problems. Among these are
o A higher than normal level of fog.
o Softening of the emulsion.
o Film specificity.
o Loss of film speed.
o Sludging of the bath from non-image silver.
When Haist's book first came out I tried a couple of the formulas. The best results were with his MM-1 formula. I am interested in seeing if this new product has succeeded where others have failed.
