An image-receiving sheet, including a sheet substrate, an image-receiving layer which is formed on said substrate and which receives the dye migrated by heating from a heat transfer sheet and a release layer formed on said image-receiving layer, characterized in that said release layer is formed with a releasable resin having a molecular weight of 3500 to 20000.

Image-receiving sheet

The present invention is a method for transferring an image to a card by using a thermal transfer sheet having a separation layer provided on one side of a base layer and an image receiving layer on the separation layer for receiving dyes that move from a dye transfer sheet. This method includes placing the thermal transfer sheet on the card and pressing them between a pair of rubber roller having a hardness of 70.degree. to 90.degree. heated to a temperature of 130.degree. C. to 180.degree. C. under a pressure of 3 to 15 kg/cm.sup.2.

Image transfer method for cards

A label having a sublimation transferred image constituted of an image-receiving sheet, comprising a tacky layer, a sheet substrate and an image-receiving layer laminated in this order on a peeling sheet. The tacky layer, sheet substrate and image-receiving layer form a label portion, and the image-receiving sheet has a structure peelable between the label portion and the peeling sheet. The label has one or more frames of sublimation transferred images formed by transfer of a sublimable dye in a colorant layer of a heat transfer sheet by heating according to an image information. The label portion is applied with half-cut treatment with cutting lines for sectionalizing every frame of the sublimation transferred image.
