ABSTRACT:
A photographic material comprising a light sensitive silver halide emulsion layer and an antistatic layer is disclosed., wherein at least one of the hydrophilic colloidal layers is hardened by a hardener represented by a formula of ##STR1## wherein R.sub.1 and R.sub.2 represent each an alkyl group having 1 to 3 carbon atoms, an aryl group or an aralkyl group, provided, they may be the same with or the different from each other and they may so associate together as to represent `an atom group necessary to form a piperidine ring or a morpholine ring` in which the piperidine ring or the morpholine ring may each be substituted with an alkyl group or a halogen atom; R.sub.3 represents a hydrogen atom, a methyl group or an ethyl group; R.sub.4 represents a methylene group, a propylene group or a simple chemical bond; Me.sup.+ represents an alkali-metal cation; and X.sup.- represents an anion. The photographic material has preferable antistatic property and is suitable for the use of lithographic film.
