Abstract

Stabilizing baths used in rapid reproduction processes of photographic elements which comprise stabilizers, hardening additives and corrosion preventatives are improved in that certain heterocyclic compounds are incorporated in the baths. Excellent protection against corrosion is attained without a deleterious effect on the quality of the photographic material.
