Technicolor did revive the dye transfer process in the nineties. If you saw "Apocalypse Now, Redux" you saw what will probably remain the last wide release IB print. These prints were much more expensive to produce (think of it: pin-registered film processing), and the upper management pulled the plug after a couple of years. Watch for Apocalypse Now Redux at your local revival house or repertory theatre. These "revived" prints were made with a new set of more permanent dyes, so the prints will be around for a long time, looking just as spectacular as when they were released. I think I will ask the Pacific Cinematheque, here in Vancouver, to get ahold of a print. There are some reds that you've never seen on a theater screen unless you've seen an IB print.
