MULTI-COLOR IMAGE-FORMING MATERIAL AND MULTI-COLOR IMAGE-FORMING PROCESS

摘要

A mufti-color image-forming material is disclosed comprising image-receiving sheets each having an image-receiving layer and heat transfer sheets for at least four colors, including yellow, magenta, cyan and black, each having at least a light-to-heat conversion layer and an image-forming layer on a support, the heat transfer sheets and the image-receiving sheets being respectively laminated such that the image-forming layer of the heat transfer sheet and the image-receiving layer of the image-receiving sheet are opposed to each other, whereby the irradiation with laser beam causes the area irradiated with laser beam on the image-forming layer to be transferred onto the image-forming layer in the image-receiving sheet to effect image recording, wherein the thickness of the image-forming layer in the heat transfer sheets is from 0.01 .mu.m to 1.5 .mu.m and the width of lines in laser-transferred image is from 0.8 to 2.0 times a half of the half-width (i.e., the half width at half maximum) of the distribution in the direction of subsidiary scanning of the integration of the binary energy distribution of laser beam spot in the direction of main scanning.
