So, Polaroid, with a large R&D staff and many millions of dollars, managed to produce stable SX-70 film in 1966 and onwards with other integral films.
Was this process described in a patent? Probably not, as it would've expired by now and be available to copy. So it remained a trade secret. Still, I'm surprised that Impossible has gotten this far, yet cannot get that final crucial step of image stability.
Considering the extreme cost of this film, and the short term image quality, I'm amazed that they can stay in business.
