  The present invention provides a photographic element comprising a dimensionally stable hydrophobic transparent polyester film support, at least one light-sensitive silver halide emulsion layer, and at the side of said support opposite to that of said emulsion layer(s), a subbing layer essentially consisting of poly-N-vinyl pyrrolidone, and an antihalation layer comprising carbon black dispersed in a water-insoluble alkali-soluble copolymer of 1 to 65 % by weight of a C₁-C₄ alkyl methacrylate, 10 to 79 % by weight of a C₁-C₈ alkyl acrylate, and 10 to 50 % by weight of acrylic acid or methacrylic acid. The present invention also provides a process of manufacturing a dimensionally stable hydrophobic transparent polyester film support carrying a subbing layer and an alkali-soluble carbon black antihalation layer, said process comprising monoaxially stretching an extruded amorphous polyester film, coating it with an aqueous solution of poly-N-vinyl pyrrolidone to form said subbing layer, drying it, stretching it together with said film in a direction perpendicular to that of the first stretching, heat-setting, coating the film support with an aqueous dispersion of carbon black in said above-mentioned water-insoluble alkali-soluble copolymer to form said alkali-soluble antihalation layer.

  本发明提供了一种感光元件，它包括一个尺寸稳定的疏水透明聚酯薄膜支撑层，至少一个感光卤化银乳剂层，以及在所述支撑层与所述乳剂层相对的一侧，一个主要由聚-N-乙烯基吡咯烷酮组成的吸附层、和防光晕层，防光晕层包括分散在不溶于水的碱溶性共聚物中的炭黑，该共聚物的重量百分比为 1-65%的甲基丙烯酸 C₁-C₄烷基酯、10-79%的丙烯酸 C₁-C₈烷基酯和 10-50%的丙烯酸或甲基丙烯酸。本发明还提供了一种制造尺寸稳定的疏水性透明聚酯薄膜支撑物的工艺，该支撑物带有 底层和碱溶性炭黑防晕染层，所述工艺包括单轴拉伸挤出的无定形聚酯薄膜，用聚-N-乙烯基吡咯烷酮水溶液涂覆以形成所述底层、将其干燥，与所述薄膜一起沿垂直于第一次拉伸的方向拉伸，热固，在薄膜支撑物上涂上碳黑在上述不溶于水的碱溶性共聚物中的水分散液，形成所述碱溶性防光晕层。
