Their numerous "No Suggested Replacement" says it all. Not interested in Chemical Photography anymore.
Well, go though the list, then.
A couple (toners, reducers, inverters, stab, hardener) will have been discontinued for regulatory reasons - they contain poisons like selenium, prussic acid or allergens like formaldehyde, and have been cancelled by many makers.
A couple of others are bulk-size raw chemicals, where Kodak cannot be competitive with chemistry dealers - photography is hardly dead if you have to buy your thio or glacial from the chemistry dealer in town rather than having it shipped from Rochester.
Then there are some processes which are not used any more. Nobody starts or replenishes big tank compensating developer any more - that was a technology used for low grade bulk consumer development, and that is positively gone. There is no market left for film in applications cheaper and more ugly than digital.
"Royalprint" was a activate-and-stabilize semi-dry rapid RC processor used in copier applications, by rural photo stores to eliminate water from their dwindling back room b&w printing business, and by press labs for rush printing. Photographers hated it, as the prints were fading or blackening within weeks. Scanners and laser copiers/printers had already pretty much killed it before the first digital cameras appeared. I guess if there had not been some military or governmental long term contract that stuff would have been discontinued and forgotten by the mid nineties at the very latest.
Selectol-Soft has been obsoleted by Kodak cancelling the matching paper.
That leaves Retouching Fluid and Microdol-X as the only items (maybe) actively killed by Kodak.
