Narrative:

Flight took off with 2 of the 4 method 2 drift-down alternates illegal; I noticed this shortly after the flight departed den as I was checking all of my flts' drift-down alternates. I noticed after departure because I had a flight declare an emergency that took up some time that I could have used to check the drift-down alternates. After the emergency was under control I noticed the error with the alternates and I changed the 2 illegal alternates to legal ones and amended release with the captain.
