摘要： The present invention relates to a light-sensitive silver halide color multilayer photographic material which comprises a support base having coated thereon at least three red-sensitive emulsion layers having different sensitivity, at least three green-sensitive emulsion layers having different sensitivity, and at least two yellow-sensitive emulsion layers having different sensitivity, wherein

(a) a core-shell silver halide emulsion having an average silver iodide content lower than 10% mol is present in at least one of the lowest sensitive red-, green-and yellow layers,
(b) a yellow dye forming malonodiamide DIR coupler having in the coupling position thereof a 4,7-dihalogen-2-benzotriazolyl group is present in both the medium sensitive red- and green-sensitive layers, and
(c) a yellow dye forming DIR coupler having a 1,2,4-triazolyl group attached to the coupling position, such 1,2,4-triazolyl group comprising a hydrolizable alkoxy-or aryloxy-carbonyl group attached to a benzytlthio substituent on the 1,2,4-triazolyl group is present in at least one of the highest sensitive red- and green-sensitive layers.

摘要： The present invention relates to a light-sensitive emulsion, and a light-sensitive photographic material containing the same, comprising silver bromoiodide grains of a core shell structure comprising a) an inner core consisting essentially of silver bromide or silver bromoiodide, the silver iodide content of said inner core being within the range of 0 to 10 mole %, and b) a plurality of shells consisting essentially of silver bromide or silver bromoiodide, wherein a pure silver iodide phase representing from 0.1 to 5 mole% of the total silver halide grain content is interposed between two adjacent shells, and wherein at least one of said adjacent shells has a silver iodide content higher than 5 mole%.
