In my direct message to Judy I mentioned the old stripping papers Kodak and
others used to make. These were conventional silver bromide papers coated
on a relatively thick coating of soluble gelatin. You'd expose and process
the paper normally. When dry you could transfer the image onto a wide
variety of surfaces as in the carbon transfer process, i.e., *hot* water
made the backing easily removable.
Gum prints can be developed in *cold* water without affecting gelatin for a
considerable amount of time (several hours anyway; hardened gelatin can
last one week under water before it decomposes). Of course, if your paper
is glued with gelatin on a support, you can expect the exposed dichromated
gum to harden your gelatin as well. I read in a patent that a red dye in
the gelatin layer would prevent the actinic light from doing its work. This
would take a fair amount of experimentation.
