It should be fine, I believe. Kodak used to produce a special contact printing paper - "Azo" - but it was discontinued some years back. There were supplies available from Smith and Shamlee in the US a while back.
Azo was a very light weight paper base which tended to curl incredibly when wet. It probably also needed to be mounted to a sub-support once dried.
