The D 19 is a high contrast, high resolution ( and therefore an MTF close to 100%), low fog developer. Known chemical composition. In scientific applications the D 19b is often used.
The recipe of the Kodak HRP developer is unknown to me and not mentioned in the reviews I have. May be, is it the same as the Kodak 19b.

In my experience, Kodak HRP produced results that were equivalent to those produced by Kodak D19 and/or D19b. Kodak HRP was a bit easier to use than D-19, especially for making positive transparencies.
