Abstract

Ein farbfotografisches, negativ entwickelndes Silberhalogenidmaterial mit einem Träger und wenigstens einer blauempfindlichen, wenigstens einen Gelbkuppler enthaltenden Silberhalogenidemulsionsschicht, wenigstens einer grünempfindlichen, wenigstens einen Purpurkuppler enthaltenden Silberhalogenidemulsionsschicht und wenigstens einer rotempfindlichen, wenigstens einen Blaugrünkuppler enthaltenden Silberhalogenidemulsionsschicht, deren Silberhalogenide zu wenigstens 95 mol-% aus AgCl bestehen und bei dem mindestens eine Silberhalogenidemulsionsschicht bei Analogbelichtung Solarisation aufweist, zeichnet sich bei scannender Belichtung durch hohe Farbdichte und bei Analogbelichtung durch einen von der Belichtungszeit unabhängigen Kontrast aus.A color photographic, negatively developing silver halide material with one Carrier and at least one blue-sensitive, at least one yellow coupler containing silver halide emulsion layer, at least one green sensitive, at least one silver halide emulsion layer containing magenta couplers and at least one red-sensitive, containing at least one cyan coupler Silver halide emulsion layer, the silver halides of which are at least 95 mol% consist of AgCl and in which at least one silver halide emulsion layer has solarization with analog exposure, stands out with scanning exposure due to high color density and with analog exposure through one of the exposure time independent contrast.
