Abstract
Direct-print images of improved stability against prolonged light-exposure are obtained in a photodevelopable element by spectrally sensitizing the photodevelopable emulsion, providing in the emulsion layer or a superposed layer a compound absorbing radiation in the inherent sensitivity range of the silver halide, and effecting image-wise exposure with radiation comprising light of the spectral range for which the silver halide has been spectrally sensitized.
