In photographic silver halide material, with a base and light-sensitive silver halide emulsion layer(s) containing 3-phenylbenzofuran-2-one(s) and a long-chain alk(en)ol(s) or acyl-, cyano-, nitro- or fluoro-phenol(s). Photographic silver halide material has a base, light-sensitive silver halide emulsion layer(s) and light-insensitive layer(s) containing 3-phenylbenzofuran-2-one(s) of formula (I) or (II) and also long-chain alk(en)ol(s) of formula R<31>-OH (III) or acyl-, cyano-, nitro- or fluoro-phenol(s) of formula (IV). R<1> = H, alkyl or acyl; R<2>, R<3> = (cyclo)alkyl, alkenyl, (het)aryl, halogen, OR<4>, SR<5>, NR<6>R<7>, NO2, CN, SO2R<8>, COOR<9> or COR<10>; R<4>, R<5>, R<6> = alk(en)yl, cycloalkyl or (het)aryl; R<6>, R<7> = H, R<4>, COR<10>, COOR<9> or SO2R<8>; R<8>, R<10> = alk(en)yl, cycloalkyl, (het)aryl or NR<6>R<7>; R<11>, R<12> = (cyclo)alkyl, (het)aryl, halogen, SR<5>, NR<6>R<7>, NO2, CN, SO2R<8>, COOR<9>, COR<10> or H; R<13>, R<14> = OR<15> or R<11>; R<15> = H, alkyl or aryl; R<31> = alkyl or aryl; R<32> = H or alk(en)yl; R<33> = alk(en)yl or (het)aryl; R<34> = H, aryloxy, alkoxy, alkylthio, (het)arylthio or halogen; R<31> = alk(en)yl with >= 8C atoms; R<32> = acyl, CN, NO2 or F; R<33> = alk(en)yl, aryl, Cl, acyloxy or acylamino; n, m, o = 0-4; p = 0-3; q = 1 or 2; r = 0-4; q+r = at most 5; or Two R<2>, R<3>, R<13>, R<14> groups = a condensed carbo- or heterocyclic ring; or R<1>, R<2> or R<3> and R<13> or R<14> = a group bound to a polymer chain; Two R<32>, 2 R<33> or one R<32> plus one R<33> groups = 5-6-membered aliphatic or aromatic ring; the R<32> and R<33> groups = groups containing a total of >= 4 C atoms
