44638CAN2A Multilayer Photographic Elements Having Improved Coating Quality ABSTRACT OF DISCLOSURE A multilayer photographic element comprising at least one light-sensitive emulsion layer comprising silver halide grains dispersed in a hydrophilic colloid and at least one auxiliary hydrophilic colloid layer, said plu- rality of layers of different composition being simultane- ously coated onto a hydrophobic support from aqueous hydrophilic colloid compositions, presents improved coat- ing quality if at least one auxiliary hydrophilic colloid layer comprises a) an anionic surface active agent, b) at least one of betaine, N-oxide or amide surface active agent the and c) at least one of dispersed droplets of a water-immiscible high-boiling organic solvent, a vinyl addition polymer latex ox a highly deionized gelatin. All the layers can be simultaneously coated from said different hydrophilic colloid aqueous compositions while mantaining a distinct layer relationship and avoiding any coating defects.
