摘要：
A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein said emulsion layer or other hydrophilic colloid layer contains a colored polymer matting agent. The colored matting agent comprises a dye adsorbed to a polymer. The dye is selected to adsorb light in the same wavelength region that to which the photographic material is exposed. Use of the present invention inhibits the occurrence of black spots.
