    • A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing.
    • 描述了制造彩色图像的方法,其中具有临时支撑膜,着色感光层和可被热活化的粘附促进层的感光材料在高温和压力下被层压, 在载体上携带含有白色颜料的颜料层的图像接收材料。 感光层被成像曝光并显影以产生图像,临时支撑膜在曝光之前或之后从图像接收材料剥离,并且如果需要,重复这些步骤至少一种其它着色的感光材料 层具有另一种颜色以产生多色图像。 该方法给出了与半色调原版相比具有较小点扩大的彩色图像,并且特别适用于用于多色打印的复印的颜色测试。

    • The present invention relates to a process for preparing a multicolored proof, using a radiation-sensitive recording material which comprises a temporary, sheet-shaped layer support, a thermally transferable layer containing a colorant in one primary color and a radiation-sensitive layer. The process comprises the steps of: a) exposing the recording material imagewise b)developing the exposed layer with an aqueous-alkaline solution to uncover the thermally transferable image areas, and c) contacting the coated side of the recording material with an image receptor and transferring the transferable image areas to the image receptor, with the application of heat and pressure, to produce a partial image in the first primary color. The above-described process steps are repeated at least once, using a radiation-sensitive recording material which contains a colorant in another primary color in its thermally transferable layer. Depending upon the respective embodiment, the process of the invention yields a proof which can be produced by a positive, a negative or a digital method, without distorting the image thus generated by interjacent layers.
    • 本发明涉及使用包含临时片状层载体,含有一种原色着色剂的可热转移层和辐射敏感层的辐射敏感记录材料来制备多色证件的方法。 该方法包括以下步骤:a)成像曝光所述记录材料b)用碱性水溶液显影所述曝光层以揭露所述可热转印的图像区域,以及c)使所述记录材料的涂覆侧与图像接收器接触, 通过施加热和压力将可转印图像区域转印到图像接收器,以产生第一原色的部分图像。 使用在其可热转移层中含有其它原色的着色剂的辐射敏感记录材料,重复上述处理步骤至少一次。 根据相应的实施例,本发明的方法产生可以通过正,负或数字方法产生的证明,而不会使由相邻层产生的图像失真。
