Abstract
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 PA1 (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, PA1 (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 PA1 (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.
