Abstract (en)
Negative colour photographic Ag halide (AgX) material has a transparent film base with at least two blue-sensitive (BS), at least 2 green-sensitive (GS) and at least two red-sensitive (RS) AgX emulsion layers with yellow, magenta and cyan couplers resp. and a yellow filter layer. The layers with the same spectral sensitivity have different speeds and the yellow filter layer is nearer the film base than the BS emulsion layers and the GS and RS emulsion layers are nearer the base than the yellow filter layer. The novelty is that: (a) at least one of the fastest GS and fastest RS layers contains an effective amt. of a crown ether (I) of formula (IA), (IB) or (IC); and (b) these fastest layers contain Ag(Br,I) emulsions with 1-15 mol.% AgI. X1 = Gp. V or VI element; L1 = opt. substd. hydrocarbon gp. with at least 2 C in the main chain between two adjacent X1 atoms or X1 atom and the adjacent bridge top atom L2; L2 = bridge top atom; and n = 1-10.
Abstract (de)
Negativ entwicklendes, farbfotografisches Silberhalogenidmaterial, das auf einen transparenten Träger wenigstens 2 blauempfindliche, gelbkuppelnde, wenigstens 2 grünempfindliche, purpurkuppelnde, wenigstens 2 rotempfindliche, blaugrünkuppelnde Silberhalogenidemulsionsschichten und eine Gelbfilterschicht enthält, wobei die Schichten gleicher spektraler Empfindlichkeit unterschiedliche fotografische Empfindlichkeiten aufweisen, und wobei die blauempfindlichen Schichten vom Träger entfernter angeordnet sind als die Gelbfilterschicht und die grün- und rotempfindlichen Schichten zum Träger näher angeordnet sind als die Gelbfilterschicht, zeichnet sich durch eine verbesserte Entwicklungskinetik aus, wenn wenigstens eine der höchstempfindlich grünempfindlichen und der höchstempfindlich rotempfindlichen Schichten einen Kronenether enthält.
