ABSTRACT:
A multicolor image forming material in which a laser beam irradiated region of an image forming layer of a thermal transfer sheet is transferred onto an image receiving layer of an image receiving sheet, wherein: (a) a rate of heat shrinkage in the machine direction and a rate of heat shrinkage in the traverse direction of the image receiving sheet are both not more than 1% with the rate of heat shrinkage in the traverse direction being smaller than the rate of heat shrinkage in the machine direction, (b) a coefficient of dynamic friction between the thermal transfer sheet surface and the image receiving sheet surface is not more than 0.70, (c) a stiffness in the machine direction (Msh) and a stiffness in the traverse direction (Tsh) of the thermal transfer sheet are both from 30 to 70 g, a stiffness in the machine direction (Msr) and in the traverse direction (Tsr) of the image receiving sheet are both from 40 to 90 g, Msh/Tsh and Msr/Tsr are each from 0.75 to 1.20 and (Msr−Msh) and (Tsr−Tsh) are each from 10 g to 40 g or (d) at least the magenta thermal transfer sheet has a breaking stress from 150 to 300 MPa in both machine (MD) and crosswise (CD) directions with the breaking stress in the crosswise direction being at least 10 MPa larger than in the machine direction and a breaking elongation of from 80 to 300% in both machine and crosswise directions with the breaking elongation in the machine direction being at least 5 % larger than in the crosswise direction.
