| titleOfInvention | Silver halide photographic light-sensitive materials that prevent color turbidity |
| abstract | PURPOSE:To improve both light resistance and color turbidity and to solve a problem on sweating by containing a specified formula of an azenta coupler and a dialkylhydroquinone fading inhibitor in a photosensitive emulsion layer and a specified formula of a dialkylhydroguinone compound in a photosensitive emulsion layer and a non-photosensitive layer. CONSTITUTION:In a formula I Z represents a non-metallic atom group necessary to formation of a nitrogen-contained heterocycle and X represents a group capable of being separated resultant from reaction to the oxidant of a hydrogen atom or a color developing agent. R represents a hydrogen atom or a substitutional group and alkyl having the number of carbons of 1 - 32 is preferable as the substitutional group, and a straight chain or a branch can be used. A halogen atom is listed as a group represented by X and separated through reaction between the color developing agent and an oxidant. R12 and R13 in a formula II are a second grade or a third grade alkyl group, and a total sum of the numbers of carbons represented by R12 and R13 is 20 or more. The use of a specific decoloring inhibitor and a specific hydroquinone compound prevents the color turbidity, synergistically improves light resistance, and also prevents the occurrence of sweating. |
