    • The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflecttive layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.
    • 本发明涉及一种照相材料,其中依次包括透明载体,至少一层叠置在载体上的卤化银乳剂层,任选地为白色或漫反射层,背面为加工溶液可渗透的保护层, 该保护层在最终产品中不会层压或熔化而变得耐水。 本发明还涉及一种制造涉及显影照相元件的照相印相的方法。 通过支撑件观察所得到的印刷品,其提供防划伤和污渍的保护,而聚合物外涂层对印刷品的相反部分提供防水和防污染,其中轻微的划痕或损伤不是关键的,因为从该侧看不到图像 。 因此,本发明提供了对加工溶液是可渗透的韧性,耐污染和透明的观察表面和防污背面。
