PURPOSE:To prevent color stain by incorporating a specified compound into an intermediate layer and/or an emulsion layer as a color stain inhibitor. CONSTITUTION:An intermediate layer and/or an emulsion layer contg. a compound represented by the formula and having one or more optionally substituted sulfamoylamino groups on its phenol or naphthol ring as a color stain inhibitor is formed on a support. The preferred amount of the compound contained in the intermediate layer is 1.0X10<-3>-1.0X10<-5>mol/m<2>, and that of the compound contained in the emulsion layer is 1.0X10<-4>-1.0X10<-6>mol/m<2>. In the formula, R<1> is H, halogen, alkyl, alkoxy, acylamino or the like; each of R<2> and R<3> is arylsulfonyl, alkylsulfonyl or sulfamoyl; When R<1> is not sulfamoylamino, one between R<2> and R<3> is sulfamonyl; and the ring having substituted OH may form a naphthol ring together with a group of atoms Q.
