Multicolor image-forming method and multicolor image-forming material

摘要

A method for forming a multicolor image comprises:preparing: an image-receiving sheet having a support and an image-receiving layer; and at least four thermal transfer sheets each including a support, a light-to-heat converting layer and an image-forming layer, in which each of the at least four thermal transfer sheets has a different color and each of the image-forming layers in the at least four thermal transfer sheets has a ratio of an optical density (OD) to a layer thickness: OD/layer thickness (mum unit) of 1.50 or more; superposing the image-forming layer in each of the at least four thermal transfer sheets on the image-receiving layer in the image-receiving sheet, in which the image-forming layer is opposed to the image-receiving layer; irradiating the image-forming layer in each of the at least four thermal transfer sheets with a laser beam; and transferring the irradiated area of the image-forming layer onto the image-receiving layer in the image-receiving sheet to record an image, in which the transferred image onto the image-receiving sheet has a resolution of 2400 dpi or more, where in a color matching process is performed before the image is recorded on the image-receiving sheet.
