    摘要： An ink jet printing system includes an ink receiving sheet and an ink-jet printer. The ink receiving sheet includes a support, at least one receiving layer and a top coat layer. The ink-jet printer includes an ink-jet cartridge comprising an ink. The receiving layer includes a hydrophilic binder and a vinyl polymeric compound and has a total coverage weight of at least 12 g/m2, and the top coat layer is free of vinyl polymeric compounds and comprises a hydrophilic binder and a corn starch matting agent. The ink includes a dye selected from the group consisting of azo and disazo dye at a concentration higher than 4% by weight, in order to achieve an optical density higher than 3.00.

    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.
