Here is the PDF for Ektachrome 100, but any Data sheet that gives MTF will tell the same story. The Lp/mm here is about 30 at 50% contrast:
Here's the Data sheet for portra 400, where the MTF 50 of the longest wavelength red, is also about 30-40 Lp/mm:http://www.kodak.com/global/en/profe...4050/e4050.pdf
Here's Kodak Tri-x 400, a fairly lower resolution film among black and white films, it can still resolve about 50lp/mm at MTF 50: http://www.kodak.com/global/en/profe...4017/f4017.pdf
Of course there are other factors such as development and what lens you ate using, but otherwise resolution is essentially a measure of perceived sharpness at MTF50.
Don't expect the same fine details from even Kodachrome 64 slides as from say, Ilford FP4.
The image size will also affect perceived sharpness as the eye (or your computer screen) can only resolve so many line pairs at a specified distance. At a small enough size the same lens imaging on color and black and white films the same scene, the images will look indistinguishable in their "sharpness".
T-Max 400 resolves about 75 Lp/mm, while t-max
100 resolves about 120, and even the grainy P3200 can resolve about 75 Lp/mm at MTF 50: http://www.kodak.com/global/en/profe...4016/f4016.pdf
