A photographic recording material comprising a support, at least one photosensitive silver halide emulsion layer, a protective layer on that side of the at least one silver halide emulsion layer remote from the support and, optionally a backing layer, the protective layer and/or the backing layer containing in combination (a) a polymeric compound (I) containing at least 0.2 mol-% recurring units corresponding to the following formula in which R1, R2 and R3 may be the same of different and represent hydrogen, alkyl or halogen, L is a chemical bond or a standard binding link and X is a reactive group, and (b) a finely divided crystalline SiO2 dispersion having an average particle diameter (number average) of from 0.7 to 1.2 mu m and containing less than 0.2% by volume particles larger than 4 mu m in size, are distinguished by good retouchability in combination with good mechanical properties.
