摘要:
A photographic recording material which contains a support and thereupon at least one light-sensitive silver halide emulsion layer together with a protective layer containing gelatine over the light-sensitive layer and optionally a layer on the reverse side containing gelatine, and the protective layer containing gelatine and/or the reverse side layer containing gelatine contains a silicone oil of the formula I ##STR1## in which R.sub.1 means hydroxy, alkoxy, cycloalkoxy, aryloxy,R.sub.2 means a residue of the formula ##STR2## or R.sub.1 R.sub.3, R.sub.4 means alkyl, aryl, cycloalkyl,R.sub.5, R.sub.6 means H, alkyl, aminoalkyl, polyaminoalkyl,A means a straight-chain or branched alkene residue with 3 to 20 C atoms, wherein there is between the Si atom and the N atom a carbon chain of at least 3 C atoms,m means 10 to 1000 andp means 1 to 350 and is hardened, distinguished by equally good coefficients of static friction and sliding friction before and after processing and by constantly good dry scratch resistance.
