Abstract

Ein farbfotografisches Aufzeichnungsmaterial, bestehend aus transparentem Schichtträger, darauf angeordneten farbkupplerhaltigen rotempfindlichen, grünempfindlichen und blauempfindlichen Silberhalogenidemulsionsschichteneinheiten und gegebenenfalls weiteren, nicht lichtempfindlichen Schichten, wobei die grünempfindliche Silberhalogenidemulsionsschichteneinheit aus mindestens zwei grünempfindlichen Teilschichten besteht, von denen die vom Schichtträger am weitesten entfernte Teilschicht die höchste Empfindlichkeit aufweist und vom Schichtträger weiter entfernt angeordnet ist als jede Teilschicht der rotempfindlichen Silberhalogenidemulsionsschichteneinheit und wobei jede Teilschicht der blauempfindlichen Silberhalogenidemulsionsschichteneinheit vom Schichtträger weiter entfernt angeordnet ist als die höchstempfindliche Teilschicht der grünempfindlichen Silberhalogenidemulsionsschichteneinheit, enthält in der höchstempfindlichen Teilschicht der grünempfindlichen Silberhalogenidemulsionsschichteneinheit einen organischen bei der Verarbeitung entfärbbaren gelben Farbstoff; die daran auf der vom Schichtträger abgewandten Seite angrenzende nicht lichtempfindliche Bindemittelschicht enthält keine Silberhalogenidentwicklungskeime und im wesentlichen keinen bei der Verarbeitung entfärbbaren Farbstoff.A color photographic recording material consisting of a transparent substrate, color-coupler-containing red-sensitive, green-sensitive and blue-sensitive ones arranged thereon Silver halide emulsion layer units and optionally further, non-light-sensitive layers, the green-sensitive silver halide emulsion layer unit consists of at least two green-sensitive sub-layers, of which the sublayer furthest away from the substrate has the highest sensitivity has and is arranged further away from the layer support than each sub-layer of the red-sensitive Silver halide emulsion layer unit and each sub-layer of the blue-sensitive silver halide emulsion layer unit further away from the substrate is arranged as the most sensitive sublayer of the green-sensitive silver halide emulsion layer unit, contains in the most sensitive sublayer green sensitive silver halide emulsion layer unit an organic at the Processing decolorizable yellow dye; the one facing away from the layer support Adjacent non-photosensitive binder layer contains no silver halide development nuclei and essentially none that can be decolored during processing Dye.
