Abstract (en)
[origin: EP0866363A1] 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 RS unit consists of NOTLESS 2 layers sensitised with sensitising dyes giving a sensitivity curve characterised by the following parameters : 635 nm ≤ lambda (Smax) ≤ 660 nm; b80 ≥ 35 nm; b50 ≥ 56 nm; b20 ≥ 96 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.
