Photographic light-sensitive element with backing layer

Claim 1

A photographic light-sensitive element comprising at least one light-sensitive photographic emulsion layer on a support and a back layer provided on the reverse side of the support, wherein a layer comprising a hydrophilic polymer is present between the uppermost surface layer of said back layer and the support, wherein the uppermost surface layer of said back layer comprises a hydrophobic polymer and 5 to 80% by weight of a hydrophilic polymer based on the weight of the total polymers which are employed in a total amount of 0.01 to 2 g per m 2 , wherein said hydrophobic polymer is selected from the group consisting of cellulose diacetate, cellulose triacetate, cellulose acetate butyrate and cellulose propionate and wherein said hydrophilic polymer is selected from the group consisting of copolymers and homopolymers of alkyl acrylates, alkyl methacrylates, acrylic acid, methacrylic acid, sulfoalkyl acrylates, sulfoalkyl methacrylates, glycidyl acrylate, glycidyl methacrylate, hydroxyalkyl acrylates, hydroxyalkyl methacrylates, alkoxyalkyl acrylates, alkoxyalkyl methacrylates, styrene, butadiene, maleic anhydride and itaconic anhydride.
