Spectrally-sensitized silver halide emulsion, useful in photographic material, e.g. color photographic camera or copying material, is supersensitized with 1-substituted 5-oxo-, 5-thio- or 5-imino-dihydro-1,2,4-triazole compound

Color photographic material combining improved sensitivity with good storage stability is chemically ripened with a short chain xanthate and spectrally sensitized with a cyanine dye

Siegel Joerg; Borst Hans-Ulrich; Bergthaller Peter

Color photographic material with reduced fog without sacrifice in sensitivity uses a long-chain xanthate as stabilizer to counteract the fogging effect of sulfur-, selenium or tellurium ripeners

Siegel Joerg; Borst Hans-Ulrich; Bergthaller Peter

Photographic material has silver halide-iodide emulsion containing dithiocarboxy-(het)arene compound and sensitized chemically with different sulfur, selenium or tellurium sensitizer

Siegel Joerg; Borst Hans-Ulrich; Bergthaller Peter

Spectrally sensitized silver halide photographic material, especially color photographic material, contains N-unsubstituted phenothiazine and/or phenoselenazine compound(s)

Siegel Joerg; Borst Hans-Ulrich; Bergthaller Peter

Silver halide photographic emulsion comprises short-chain alkyl xanthate and divalent selenium or tellurium compound and has improved storage stability and higher sensitivity

Siegel Joerg; Borst Hans-Ulrich; Bergthaller Peter
