FWIW, here's the link to Kodak's description of the new Ektar 100. There's a link there that will get you a datasheet in PDF:

Also: This says that Ektar 100 (available in October, in 135/36 only) is to replace 100 UC, and further that 400UC is to be killed by the end of 2008. So, if you like 100UC or 400UC, now's the time to buy!
