摘要： Disclosed is a multi-color transfer image forming method, which comprises subjecting a colored image forming material having a coloration recording layer comprising at least two layers and containing a photosensitive material and a colorant on a support to aqueous development after imagewise exposure, thereby forming a colored image, transferring the colored image to an image receiving member through the outermost surface of the coloration recording layer and then transferring at least one colored image with different hue onto the same image receiving member in conformity with the colored image, characterized in that the layer of the coloration recording layer remotest from the support is a layer adherable to the image receiving member, and only the colored image portion is transferred onto the image receiving member to have the image receiving member surface exposed at the non-image portion of the multi-color image.According to the present invention, the treating process of multi-color transfer image becomes simpler and also a transferred image approximate to a printed matter can be obtained.
摘要翻译：公开了一种多色转印图像形成方法，其包括在成像曝光之后，将具有包含至少两层的着色记录层并且含有感光材料和着色剂的着色图像形成材料在载体上进行水性显影，从而形成彩色图像，通过着色记录层的最外表面将彩色图像转印到图像接收部件，然后根据彩色图像将具有不同色调的至少一个彩色图像转印到同一图像接收部件上，其特征在于，该层从支持体偏离的着色记录层是与图像接收构件相邻的层，并且仅有彩色图像部分被转印到图像接收构件上，以使得图像接收构件表面在多层图像的非图像部分处露出，彩色图像。根据本发明，多色转印图像的处理过程变得更简单，并且也可以获得接近印刷品的转印图像。
