I didn't dissect the chemistry described, but the idea isn't particularly
novel. There are several processes that make use of chemical image
transfer to form a positive. One of the most notable being the Polaroid
process. The Carbro pigment process also works by chemical hardening of
the pigmented gelatin in contact with a silver image.
