is kodak ektacolor photo paper for color, black and white or both??

Answer 1

I think this paper is just for printing color slide film.

Answer 2

As the name says, it is for color negatives. It requires a number additional developing steps, high quality temperature control of the developing baths, must be worked in total darkness [no "safelights"], and chemicals are considerably more expensive and less stable than standard b/w process.

Also, it requires heavy filtering when exposed from a b/w negative source because b/w film does not have the built-in red color base.

Bottom line, use ordinary b/w chemistry and paper for your b/w film projects.
