ABSTRACT:
A coating composition for applying a layer to a photographic element which comprises gelatin, water and from 0.35 to 1 percent by weight based on the total weight of the composition of a surfactant mixture comprising from 20 to 60 percent by weight of a mixture of anionic surfactants, from 30 to 75 percent by weight of a nonionic surfactant and from 3 to 13 percent by weight of a cationic surfactant based on the total weight of surfactant mixture; the mixture of anionic surfactants comprising from 30 to 85 percent by weight of di- and tri-isopropyl naphthalene sulfonate, sodium salts and from 15 to 70 percent by weight of a dioctyl sulfosuccinate, sodium salt; a di-fluoroalkyl sulfosuccinate, sodium salt where alkyl is C.sub.4 -C.sub.6 ; perfluoro-octyl sulfonate(tetraethyl ammonium salt) or a perfluoro-alkyl carboxylate ammonium salt where alkyl is a mixture of C.sub.5 -C.sub.8 alkyl radicals with hexyl being the major component, based on the total weight of the anionic surfactants; the nonionic surfactant being a nonyl phenoxy poly(glycidyl) alcohol and the cationic surfactant being perfluoro-octyl sulfonamide, N-hydrogen, N-propylene trimethylammonium iodide.
