Abstract
It is intended to provide a multicolor image forming material for recording an image by irradiation with laser light comprising an image receiving sheet having an image receiving layer and at least four heat transfer sheets having a light-heat conversion layer and an image forming layer, wherein the light-heat conversion layer contains a polyamide-imide of a specific structure and a cyanine colorant of a specific structure. It is further intended to provide a multiple color image forming material wherein the difference in the visible light range between the reflectance of the image forming layer of each heat transfer sheet before the irradiation with laser light and recording of an image and the reflectance of the image forming layer transferred to the image receiving layer of the image receiving sheet due to the irradiation with laser light is 10% or less, and a multiple color image forming material wherein the color difference between the color hue of the image forming layer of each heat transfer sheet immediately after the transfer to the image forming layer of the image forming sheet due to the irradiation with laser light and before exposure and the color hue thereof after exposure does not exceed 2.
