    Abstract: A photosensitive element includes a layer of a photosensitive material on a transparent, multilayer, polymeric support having numerous alternating layers of at least two different polymeric materials. The polymeric multilayer support reflects at least 50% of actinic radiation in the range of wavelengths to which the photosensitive material is sensitive. If the polymeric multilayer reflector includes numerous, thin, alternating layers located at the surface of the polymeric support closest to the photosensitive material, the element not only provides increased speed but also provides an antihalation effect. In another aspect, a multilayer reflector is located a distance removed from the photosensitive layer sufficient to reduce any woodgrain that would otherwise occur, while increasing speed.

    Abstract translation: 感光元件包括在透明的多层聚合物载体上的感光材料层，其具有至少两种不同的聚合物材料的多个交替层。 聚合物多层载体反射感光材料敏感的波长范围内的至少50％的光化辐射。 如果聚合物多层反射器包括位于最靠近感光材料的聚合物载体表面的多个薄的交替层，则元件不仅提供增加的速度，而且还提供防晕效应。 在另一方面，多层反射器位于离感光层一定距离处，足以减少否则会发生的任何木纹，同时增加速度。
