ABSTRACT OF THE DISCLOSURE A photographic element or film, such as photographic or medical X-ray film, having improved antistatic and slippage properties can be prepared by applying to said element or film a protective surface in the form of a gelatin containing antistatic composition, characterized by comprising (a) about 1% to about 2.5% by weight, based upon the total gelatin solids content of said composition, of an aqueous dispersion of a salt of a metal selected from the group consisting of Li, Na, K, Mg, Ca, Ba, Sr and Al and of a C12 - C32 organic fatty acid wherein the average particle size of the solids suspended in said dispersion is about 1 micron and the specific viscosity of said dispersion is about 350 cps to about 750 cps; added to (b) about 2.5 to about 5% by weight, based upon the total gelatin solids content of said composition, of a quaternary ammonium compound of the formula: RCONH(CH2)3N+R1R2R3,NO3- wherein R is C7-C17 alkyl, R1 is hydroxyalkyl having from 1 to 6 carbon atoms, and R2 and R3 are each C1-C6 alkyl containing a calcium stearate dispersion and stearamido-propyl dimethyl-beta-hydroxy-ethyl ammonium nitrate.
