Abstract
The keeping qualities (shelf life), and photographic speed of non-silver free radical photosensitive materials are increased by the incorporation of at least one of each of three classes of additives, namely: PA1 (1) a stabilizer, usually an alcohol or a phenol; PA1 (2) a speed enhancer; and PA1 (3) a compound which enhances the capability of heat fixing of films containing both (1) and (2).
