Highly sensitive colour photographic recording material with increased sensitiviy in the blue spectral region

Highly sensitive colour photographic recording material with increased sensitiviy in the blue spectral region

In fast colour photographic material with red-sensitive (RS), green-sensitive (GS) and blue-sensitive (BS) silver halide (AgX) emulsion units containing cyan, magenta and yellow couplers respectively and optionally light-insensitive layer(s), the BS unit consists of NOTLESS 2 layers sensitised with...

Zusammenfassung:In fast colour photographic material with red-sensitive (RS), green-sensitive (GS) and blue-sensitive (BS) silver halide (AgX) emulsion units containing cyan, magenta and yellow couplers respectively and optionally light-insensitive layer(s), the BS unit consists of NOTLESS 2 layers sensitised with sensitising dyes giving a sensitivity curve characterised by the following parameters; 460 nm ≤ lambda (Smax) ≤ 480 nm; b80 ≥ 24 nm; b50 ≥ 91 nm; b20 SIMILAR 106 nm; in which lambda (Smax) = the wavelength of the sensitivity curve maximum (100% intensity); b80. b50, b20 = the width of the sensitivity curve at 80, 50 and 20% respectively of the maximum intensity.
