Patent ID: 8119562

Claim:
A heat-sensitive transfer sheet that is used in an image-forming method using a heat-sensitive transfer system, which method comprises the steps of superposing the heat-sensitive transfer sheet having at least one yellow heat transfer layer, at least one magenta heat transfer layer, and at least one cyan heat transfer layer on a support, and a heat-sensitive transfer image-receiving sheet having at least one dye receptor layer on a support, and then transferring at least three kinds of heat transferable dyes to the dye receptor layer sequentially, which heat-sensitive transfer sheet satisfies the following Formula (1): μ1>μ2>μ3m Formula (1) where μ1 is the coefficient of static friction between a first color heat transfer layer and the image-receiving sheet having a value in a range from 0.4 to 1.0, and μ2 is the coefficient of static friction between a second color heat transfer layer and a first color solid print image-receiving sheet having a value in a range from 0.2 to 0.8, and μ3 is the coefficient of static friction between a third color heat transfer layer and a first color/second color solid print image-receiving sheet having a value in a range from 0.1 to 0.6, wherein said heat-sensitive transfer image-receiving sheet contains hollow polymer particles and a hydrophilic polymer between the dye receptor layer and the support.
