It's been a long and convoluted path, but basically yes, at least in terms of the business relationships. From memory, 3M spun off its media division as Imation, which was then bought up by Ferrania. FWIW, I don't believe I've ever seen Ferrania film for sale as such in the US, but it's pretty common as a house brand.
