Kodak sensitized paper

[dario]

Hi folks

I'm not sure if this is the right forum, but I'll give it a try.

I recently acquired a box of "Kodak Sensitized Paper". It came in a tin box that was completely sealed and required a key to open it, rather like an old sardine tin before the days of rip tops. Inside that was a regular cardbood box. See the attached.

I suspect it might be 50-100 years old.

On opening the box, the paper appeared to be in good condition, so I experimented and found:

1. It's completely insensitive to tungsten light.

2. Exposing it to daylight (with a neg in a contact printing frame) for about 1 second and developing in Dektol produces an image. The image is neutral black and white, just like a normal modern monochrome print. The image appeared rapidly and I had to take the print out of the developer long before the usual 2 minutes (but perhaps just because I'd over exposed it).

3. Exposing it to daylight (open shade on a sunny day) for about two hours produced a distinct, but not very strong, image of an orangy-brown colour.

So what have I got? My guess is that it's a chloride paper, but it seems too insensitive to be used as a regular printing-out paper, although I have no knowledge of how long typical printing-out exposures were. How would it have been used, given that it's insensitive to tungsten light? And what would it have been used for?

I'd appreciate any information.

Thanks.

You've got Eastman chloride waterproof printing or as the name says Eastman Kind 1019. It was still used in the 1940's. Can't really find more info on the paper

The outer package is made of sheet metal?

Thanks for the replies.

AgX: The outer container is (I think) tin plate (thin tin-plated steel). It had been soldered shut, so was completely air-tight.

I believe it was for contact printing and required long exposures. I would be curious to see a print made on a sheet.

Indeed, please show us a print!

Here's my first attempt at printing out (two different exposures).

Interesting.

Is that an enlargment or contact print? What developer did you use?

 

[dario]

It's a contact, printed-out (no developer) image from a 4x5 neg. About two hours exposure in open shade.

It appears now that the paper I have is a contact paper (albeit rather slow) rather than a printing-out paper.
