Kodak 5327 PHR 35mm film

[kartracer]

I have some 35mm negs with this code on the strip. The only reference I can see is for some Ektar 25 slide film using this code. Any ideas what it is?

Yes, Kodak Ektar 25 Professional PHR. They also had a non-pro Ektar 25 (CK). I still have some Ektar 25 PHR in 120 roll in the freezer with an expiration date of June, 1997.
