A composition responsive to activating energy for forming an imaging film, which composition comprises: (a) an image forming organo-metallic compound; (b) a reductant precursor which will abstract labile hydrogen from a hydrogen donor under the influence of activating radiation to become a reducing agent with respect to the image forming organo-metallic compound; (c) a masked reducing agent which ionizes under the influence of a base; (d) a source of labile hydrogen for reaction with said reductant precursor; (e) a base which is capable of ionizing the masked reducing agent, said base being present in an amount to ionize at least a portion of the masked reducing agent present in the composition, said base being of the type and present in an amount such that the speed of the film is improved; and (f) a matrix in which said organo-metallic compound, reductant precursor, masked reducing agent, source of labile hydrogen and base are combined in amounts effective to form a composition which may be applied to a substrate.
