摘要： A process of compositing two or more separate images comprising: (a) imagewise exposing a color negative photographic recording material to a subject in front of a uniformly colored screen background, wherein the photographic recording material comprises a support bearing red light, green light, and blue light sensitive color records, and at least one distributed red light absorbing compound in an amount such as to reduce the sensitivity of the red light sensitive color record by at least 40%, and the light sensitivities of the green light sensitive color record and the blue light sensitive color record are each reduced by less than 20% by the presence of any distributed light absorbing compounds, (b) forming a color negative image of the subject and screen background by developing the exposed photographic material with a color developing agent, (c) separating the subject image of the color negative from the screen background image, and (d) compositing the separated subject image with a second image. Photographic elements for use in such process are also disclosed. The invention eliminates or substantially reduces red record fringe problems without significantly effecting granularity in the blue and green color records.
摘要翻译：一种合成两个或更多个分开的图像的过程，包括：（a）将彩色负片照相记录材料成像曝光于均匀着色的屏幕背景之前的受试者，其中所述照相记录材料包括支持红色光，绿色光和蓝色感光颜色记录，以及至少一种分布式红光吸收化合物，其量使得将红光敏感色记录的灵敏度降低至少40％，以及绿光敏感色记录和通过存在任何分散的光吸收化合物，蓝色感光色记录分别减少20％以下，（b）通过用彩色显影剂显影曝光的照相材料，形成对象的彩色负像和屏幕背景（ c）将屏幕背景图像中的否定色彩的被摄体图像分离，以及（d）将分离的被摄体图像合成第二个图像。还公开了用于该方法的照相元件。本发明消除或基本上减少红色记录条纹问题，而不会在蓝色和绿色记录中显着影响粒度。

摘要： A color photographic silver halide negative working duplicating element comprising a support bearing, in order from the support, at least one red-sensitive photographic silver halide emulsion layer package comprising at least one cyan image-dye forming coupler that is capable upon exposure and processing of forming a cyan image dye that absorbs in the range of the original image; at least one green-sensitive photographic silver halide emulsion layer package comprising at least one magenta image-dye forming coupler that is capable, upon exposure and processing, of forming a magenta image dye that absorbs in the range of the original image; and at least one blue-sensitive photographic silver halide emulsion layer package comprising at least one yellow image-dye forming coupler that is capable upon exposure and processing of forming a yellow image dye that absorbs in the range of the original image. The silver halide particles in the fastest blue sensitive layer have an equivalent spherical diameter no greater than 0.3 microns, while in the remainder of the layers the silver halide particles have an equivalent spherical diameter of no greater than 0.23 microns. The silver level in the fastest blue sensitive layer is no greater than 30 mg/square foot. A sufficient red absorber is present so that the red record MTF(12) is at least 95% of the green record MTF(12) and the red record F50 is no more than 6/mm less than the green record F50.
摘要翻译：一种彩色照相卤化银负性复制元件，其包括从载体依次的至少一种红色感光照相卤化银乳剂层包装，其包含至少一种形成青色影像染料的成色剂，其能够在曝光和加工形成在原始图像的范围内吸收的青色图像染料; 至少一种感光感光照相卤化银乳剂层包装，其包含至少一种品红色成像成色剂，其能够在曝光和加工时形成在原始图像范围内吸收的品红色图像染料; 以及至少一种蓝色感光性感光卤化银乳剂层包装，其包含至少一种形成黄色成像剂的成色剂，其能够在曝光和加工时形成在原始图像范围内吸收的黄色图像染料。最快蓝色敏感层中的卤化银颗粒具有不大于0.3微米的当量球形直径，而在其余层中，卤化银颗粒具有不大于0.23微米的当量球形直径。最快蓝色敏感层的银色水平不大于30毫克/平方英尺。存在足够的红色吸收体，使得红色记录MTF（12）至少为绿色记录MTF（12）的95％，红色记录F50不超过绿色记录F50的6 / mm。
