Title: Multicolor image forming material and method for forming multicolor image
Inventor: YAMAMOTO MITSURU
IPC: B41M5/42
Filed: 2002-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a multicolor image forming material and a method for forming a multicolor image which can provide a DDCP of a large size having a high quality level/high stability and excellent printing coincidence by preventing a vacuum close contact fault or a wrinkle generated in response to each size difference of a thermal transfer sheet, an image forming sheet and text paper. SOLUTION: The multicolor image forming material comprises the image receiving sheet having an image receiving layer, the thermal transfer sheet having a photothermal conversion layer and an image forming layer and containing a plurality of different colors. The image forming material records the image by superposing the image forming layer of each thermal transfer sheet and the image receiving layer of the image receiving layer and transferring a laser beam irradiating region of the image forming layer onto the image receiving layer by irradiating with the beam. In the material, a ratio of an optical density(OD) of the image forming layer/a layer thickness (unit: μm) is 1.50 or more, an image recording area is 515 mm or more ×728 mm or more, and a resolution of the transfer image is 2,400 dpi or more.  Each thermal transfer sheet is larger by 20 to 80 mm than the image receiving sheet, and text paper is larger by 5 to 100 mm than the image receiving sheet. The method for forming the multicolor image uses the multicolor image forming material.
