I was just thinking... Aerochrome didn't require an infrared filter (like a Hoya R72) to shoot. Or a tripod. Most just slapped a yellow filter over the lens to block the blue light from coming in. So if they made the "red" layer IR sensitive with a cyan dye, the "green" layer red sensitive with a magenta dye, the "blue" layer green sensitive with a yellow dye, then put the yellow filter layer on over that, then the filter would be built-in and the user wouldn't have to remember the filter that way either.

Oh and I checked the page the OP linked to, and they've sold out of this emulsion already. I guess they were doing 4,000 rolls of 120 and 3,500 rolls of 35mm.
