ABSTRACT:
The matting agent particles of matted photographic imaging materials contain a finely divided solid as well as a dye that is only present at the image-forming points after exposure and development of the material. The starry night effect is thereby avoided. The dye can be formed during exposure and development from a precursor, e.g., from silver halide or from couplers for color photography or for diazo processes.
