    • The invention relates to color photographic materials used for color image recording in the visible and infrared regions. The inventive material consists of a polymer base on one side of which an ant-halo backing is coated and at least two light-sensitive layers are coated on the other side. A light-sensitive layer is made from silver bromide-iodide emulsion containing microcrystals with octahedral or flattened faces or mixture thereof and with grains ranging from 0.5 to 1.5 mu m. One light-sensitive layer (in case of two or more layers) comprises an infrachromatic sensitizing polymethine dye corresponding to formula (I) cited in the description. The other light-sensitive layer comprises more than one orthochromatic polymethine dye of formula (II) cited in the description. The third light-sensitive layer, if any, comprises polymethine dye of formula (III) cited in the description. Auxiliary gelatin layer containing a hardener are applied between the light-sensitive layers. As a hardener preferably triazine-1,3,5 is used. This material possesses a high photographic sensitivity and resolving power.
    • 本发明涉及用于可见光和红外区域彩色图像记录的彩色照相材料。 本发明的材料由聚合物基体组成,在聚合物基体的一侧上涂覆有抗卤素背衬并且在另一侧上涂覆至少两个光敏层。 感光层由溴化银 - 碘化物乳液制成,该乳液含有具有八面体或平坦面的微晶或其混合物以及0.5-1.5μm的颗粒。 一个感光层(在两层或更多层的情况下)包含对应于说明书中引用的式(I)的富内色敏化聚甲炔染料。 另一个光敏层包含在说明书中引用的多于一种式(II)的正色多次甲基染料。 第三光敏层(如果有的话)包含说明书中引用的式(III)的聚甲炔染料。 含有硬化剂的辅助明胶层被施加在光敏层之间。 作为硬化剂,优选使用三嗪-1,3,5。 这种材料具有很高的照相感光度和分辨率。
