摘要

Abstract of the DisclosureLight-sensitive colour photographic materialwhich contains on a base in at least onesilver halide emulsion layer or an interlayer which isassigned to this and does not contain silver halide, atleast one DIR coupler of the formulain which R is alkyl having 1to 18 carbon atoms or aryl, D is hydrogen, optionallysubstituted alkyl having 1 to 18 carbon atoms, cyclo-alkyl having 3 to 10 carbon atoms, alkenyl having 2 to 18carbon atoms, cycloalkenyl having 5 to 10 carbon atoms,aralkyl having 7 to 18 carbon atoms, cyano or halogen andG is a optionally substituted aliphatic hydrocarbonradical having 1 to 18 carbon atoms, the sum of the carbonatoms in the substituents D and G being at least 5, L1 ishydrogen or alkyl having 1 to 5 carbon atoms, L2 is alkylhaving 1 to 18 carbon atoms, phenyl or phenyl substitutedby halogen, alkyl or alkoxy, each having 1 to 18 carbonatoms, acylamino, sulphonamide groups or carboxamidegroups and X is sulphur or selenium, and wherein thetriazolyl radical released during the reaction of thecoupler with an oxidation product of an aromatic developercontaining primary amino groups has development-inhibitingeffects.The DIR-couplers can contribute substantially to improvinginterlayer colour correction and to the image grain and thesharpness of the photographic images obtained after imagewiseexposure and usual processing of said photographic material.
