Multicolor image-forming material and multicolor image-forming method

A multicolor image-forming material comprising:

• an image-receiving sheet comprising a support and an image-receiving layer;
• and
• at least four thermal transfer sheets each comprising a support, a light-to-heat converting layer and an image-forming layer, the at least four thermal transfer sheets comprising yellow, magenta, cyan and black thermal transfer sheets,
• wherein image-recording is performed by the method comprising the steps of:
• superposing each one of the at least four thermal transfer sheets on the image-receiving sheet to be in a state of the image-forming layer being in contact with the image-receiving layer;
• and
• irradiating the thermal transfer sheet with laser beams in two-dimensional array to transfer an image in an area of the image-forming layer subjected to irradiation onto the image-receiving layer, and
• a recording area of a multicolor image in each of the thermal transfer sheets is a size of 515 mm×728 mm or more, a resolution of the transferred image is 2,400 dpi or more, and each of the light-to-heat converting layers comprises from 9.2 to 20% by weight of a substance which is liquid at 30° C.
