Photographic material, with spectrally sensitized silver halide emulsion layer(s) on a base, contains 1,2,4-triazoline 3-thio- or -seleno-ether compound(s) (I). Photographic material, with spectrally sensitized silver halide emulsion layer(s) on a base, contains 1,2,4-triazoline 3-thio- or -seleno-ether compound(s) of formula (I). X = sulfur (S) or selenium (Se); R<1> = aryl or heterocyclyl; R<2> = alkyl, alkenyl, alkynyl, aralkyl or hetarylalkyl; R<3> = alkyl, alkenyl, aryl, aralkyl, hetaryl or hetarylalkyl; R<4> = hydrogen (H), alkyl, alkenyl, aryl, aralkyl, hetaryl or hetarylalkyl; R<3>R<4> = atoms completing a carbocyclic or heterocyclic ring.
