The data is on the Kodak website (MTF Curves):

I think there is an error on MTF curve on your Kodak link for k25, the MFT is displaying 100t 7248/5248 film stock and not k25. So is k25 the winner of the resolving power contest between k40 and 7245?

Try this:

On more recent films, Kodak is publishing MTF data for all three colors, rather than a single "neutral" curve.

Yes, K25 was discontinued several years ago.
