From Kodak Professional Black and White Films pamphlet F-5 (9-69):

"A high contrast panchromatic film 0n .007-inch acetate base for copying originals containing colored lines or printed matter on either white or colored paper. Various filters can be used to increase separation between colors that photgraph in similar tones of gray or to eliminate a color if desired. ... "

The film is rated at ASA 100 for white flame arc illumination, 80 for tungsten. It was rated as fine grain and very high resolving power. Recommended developers were D-11 for 4 minutes for high contrast and D-8 for 2 minutes for maximum contrast. The recommended time in D-11 gave a contrast index of 2.8. This is an inherently very high contrast film (although not as contrasty as litho films). For more or less continuous tone, document film developers, POTA, or very dilute developers will probably be needed. These will no doubt reduce the film speed. I used a bit of Contrast Process Ortho, a related film, with D-76 once upon a time, and I got continuous tones but still extreme contrast, not good for ordinary work.
