    摘要: 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 plurality of layers of different composition being simultaneously coated onto a hydrophobic support from aqueous hydrophilic colloid compositions, presents improved coating 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 or a highly deionized gelatin.All the layers can be simultaneously coated from said different hydrophilic colloid aqueous compositions while maintaining a distinct layer relationship and avoiding any coating defects.

    摘要: The present invention relates to a support base for light-sensitive photographic elements. In particular, the present invention relates to a support base comprising a support having coated thereon at least two antihalation layers overcoated by a protective layer. The support base for light-sensitive photographic elements of the present invention presents an improved coating quality with a reduced formation of mottle, defined as an irregularly patterned defect due to the tendency of the coated layers to reproduce any deformation present on the support.
