I believe it is their line of budget consumer paper for running through minilabs and churning out a bazillion cheap 6x4's. Thinner base, etc. I've no idea how the emulsion relates to the various Endura grades (Portra, Supra, Ultra).
It's been around since about 2003 I think and Endura is still sold so I don't think it's any form of replacement.
Lately I've been printing with a bunch of different kodak emulsions - outdated (late 2011) but frozen supra endura, supra endura vc, supra premiere, edge and royal. Edge and Royal are the exact same emulsion except that royal has backprint and a thicker base. Both edge and royal are useable but they actually have weaker contrast than all the other kodak offerings listed above due to the fact that they produce a very weak black. The pro papers look a hundred times better. Too bad the premiere is so damn contrasty...
I just found on Wilhelm site that Kodak Ektacolor Edge Generations has only 1/2 the stability of Fuji Crystal Archive. While I believe Kodak Endura was close to Fuji paper.
Question: Does Kodak currently sell ANY Endura equivalent in rolls?
The local lab that I use for prints from digital files (because that is all they do) goes through large quantities of Endura - I've seen their shipments arrive.

Same problem with Fuji once you want anything bigger than 20x24 - you have to cut from rolls now,
though there is still a fair amt of slightly older paper around in cut sheet up to 30x40. I finally started
cutting from a forty-inch-wide roll a week ago. It was polyester based and damn heavy, but I managed
just fine on one of my less arthritic finger days. Fortunately, the special cutting table I made for it
worked perfectly on the first try.
