Abstract : The purpose of this program was to develop highacuity diaxo-reproduction materials to meet the duplication requirements of aerial reconnaissance films. Initially, the selection of diazofilms for this application is attributed chiefly to their inherent ability to generate copies through several generations with minimum loss in resolution. Other advantages of diazofilms include dry-processing, direct and reversing capability and print durability. The research program was directed toward producing: an improved positive-working diazofilm, a new negative-working diazo photo-reproduction system, a laboratory model ammonia-processing unit capable of independent control of the variables affecting development, and detailed information on the performance characteristics of the materials produced. The principal objectives of the program were achieved. The most noteworthy accomplishment was the development of the negative-working diazofilm. This new photo-reproduction method makes possible a complete diazo photo-reproduction system in which aerial negatives can be reproduced as positives or negatives on a variety of translucent or opaque base supports.
