A multi-layer light-sensitive photographic material comprising a support and a light-sensitive layer, which have a surface layer which does not adhere even under a high temperature and high humidity conditions when the front surface layer thereof is contacted with the other surface layer and which is hardly subject to scratching and free from the so-called 'blooming' phenomenon. The light-sensitive material according to this invention comprises, in at least one of the front and back sides thereof, at least one light-insensitive layer containing a high polymer having at least 20% by weight of a repeating unit represented by the formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a methyl group, and R.sup.2 represents a straight chain alkyl group having 12 to 24 carbon atoms.

Light-sensitive photographic material

A photographic material comprising a light sensitive photographic layer and a support having thereon in order a layer containing alumina sol including colloidal particles and an electrolyte and a layer containing a hydrophobic polymer.

Light-sensitive photographic materials with improved antistatic layers

Static resistance of a light-sensitive silver halide photographic material is improved by treating said material with a solution or dispersion of a polymer containing quaternary ammonium groups, and which also acts as an antifoaming agent in processing solutions. The polymeric moiety of the polymer has the formula ##STR1## WHEREIN R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are individually a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms; A and B are individually an alkylene group having 1 to 4 carbon atoms, a hydroxymethylene group, a phenylene group or a mere bond; X.sub.1.sup..crclbar. and X.sub.2.sup..crclbar. are individually an anion; and n is an integer of 10 to 30.

Light-sensitive silver halide photographic materials containing

A photographic film comprising a plastic support having first and second layers therein in that order, the first layer comprising a cellulose acetate together with a matting agent composed mainly of silicon dioxide of less than 1 .mu. in particle size, the second layer comprising a phosphoric acid ester, or an amine salt thereof of a C.sub.8 to C.sub.22 -higher alkyl alcohol. A light-sensitive emulsion layer is carried on the other side of the support.
