摘要： There are provided a method for forming a print obtained by transferring a transfer layer from which a removal region has been accurately removed onto a transfer receiving article and a method for peeling off a transfer layer by which a removal region of the transfer layer can be accurately removed. The method for forming a print comprises, by using a transfer film in which a transfer layer is provided on one surface of a support, a thermal transfer sheet in which a peel-off layer is provided on one surface of a substrate, and a transfer receiving article, a step of removing a removal region of the transfer layer of the transfer film by means of the peel-off layer of the thermal transfer sheet and a step of transferring the transfer layer from which the removal region has been removed onto the transfer receiving article. A print is obtained by preparing a transfer film 10 in which a transfer layer 5 is provided on one surface of a support 1 and (i) a thermal transfer sheet 100 in which a fusible layer 52 and a peel-off layer 51 are provided on the same surface of a substrate 50, or (ii) a first thermal transfer sheet 100A in which a fusible layer 52 is provided on one surface of a first substrate 50A and a second thermal transfer sheet 100B in which a peel-off layer 51 is provided on one surface of a second substrate 50B, transferring the fusible layer 52 onto at least a portion of the removal region of transfer layer 5, then, removing the removal region of the transfer layer 5 by means of the peel-off layer, and subsequently, transferring the transfer layer 5 from which the removal region has been removed onto a transfer receiving article 300.
