Looking for thoughts on developing times for Polaroid Type 55 neg processed with HC110 in trays. I will have some HC110 Dilution H mixed up for developing some Arista EDU but of course I can mix other dilutions if necessary. I didnt have too many sheets to start with and will have 4 whole sheets for testing and to get things ironed out. Im thinking of starting with 9 minutes and adjusting from there?

I must admit I'm a bit confused.
Polaroid type 55 negs are already 'developed' when you open them up and separate them from the positive.
The only thing I've had to do is bathe them in sodium sulfite to get rid of the anti-halation coating on the back.
Wally if the pods are crystallized then it is better to just open them up and develop the film.
Ken- IIRC the negative was a Kodak film and it could have been something like Panatomic-X or Double-X. You may want to start with the times for those films. Good luck!
That is correct, my pods seem to have dried up so using them for the neg. Looks like 8 or 9 minutes is a good starting point, if in fact it is Panatomic-X or Double-X. I should know soon enough.
Thanks

I used to do just that. Process the negs in HC110. Back in the mid 1980s it was Panatomic X. But I believe when Kodak and Polaroid had their falling out, when kodak started putting out a polaroid type instant camera, I believe Polaroid changed the film. I can't verify it but I had it that it was changed to a fuji film. Not that it matters.

Kodak supplied the negative film for T-55, start to finish. It was similar to, if not identical to, Panatomic-X. I don't know what developing times will work for you, but I'd guess that a using a high dilution will make finding the right time/contrast level easier.
Oh, this is good info. I have one unopened box of Type 55 in the film fridge. While I hope the pods are not crystallized, if they are I think I will try Rodinal 1:100 @ ~ 20 minutes.
Finally got around to processing the Type 55. I used Kodak HC-110 dilution H at 9, 10 and 12 minutes, taco method. To my eye, I saw very little difference in the negs between the 3 times. Here is one of the test shots. This one was the 10 minute time. Slight curve adjustment at the scan and then in PS. Not too bad, looks like my scanner is producing some lines towards the top of the image. FYI don't squeeze the pods to hard when removing film from envelope!

Darn... Why didn't I think of doing this? About three years ago I threw away several boxes of Type 55... must have been six or eight.
Yikes!must have been six or eight
