A photographic silver halide material is provided which comprises in at least one layer a solid dispersion of a water-insoluble dye of the formula <IMAGE> (1) wherein each of L, L' and L'' are an optionally subsituted methine group, n is 0 or 1, Q is an optionally substituted aryl group or an optionally substituted heteroaromatic group, R1 represents a hydrogen atom or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical or an optionally substituted amino group, R2 represents a hydrogen atom or a hydroxy, amino, -CN, -COOR1, -CONR1R2 or -COR1 group or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, and R3 represents a -CN, -COOR3, -CONR3R4, -SO3H, -SO3(-) or -COR3 group, where R1, R2, R3 and R4 each independently represent a hydrogen atom or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, in a binder. The solid dispersion of the dye is finely divided in the binder material of said layer which normally is a filter or anti-halation layer. A marked increase in sharpness of the images obtained from photographic material containing in at least one layer the solid dye dispersion can be observed. |
