Abstract:
1. A method of producing a scratch print product comprising the steps of: providing an information recording thermal transfer sheet provided with a coloring agent transfer layer on one surface of a first substrate film; preparing a transfer-receiving material on which information is recorded in advance by overlapping the coloring agent transfer layer of the information recording thermal transfer sheet on a print surface of the transfer-receiving material on which no information is recorded such that the coloring agent transfer layer faces the print surface and by transferring the coloring agent to the print surface by heating to record the information; providing a scratch layer transfer sheet comprising a second substrate film or the first substrate film and a transferable scratch layer disposed on one surface of the second substrate film or the first substrate film, said transferable scratch layer having a multilayer structure disposed on the surface of the second substrate film or the first substrate film and comprising a pattern layer, which is formed pattern-wise on selected portions of the substrate surface, and a hiding layer, which is formed on portions of the pattern layer and on the substrate surface not covered by the pattern layer, wherein the pattern layer and the hiding layer are transferable to the print surface of the transfer-receiving material and removable from said print surface by scratching after the transferable scratch layer is transferred; overlapping the transferable scratch layer of said scratch layer transfer sheet on the print surface of said transfer-receiving material such that the transferable scratch layer faces the print surface to transfer said transferable scratch layer to the print surface by heating; wherein, when the areas respectively occupied by said pattern layer and said hiding layer are compared with each other, the proportion of the area occupied by the pattern layer (pattern ratio) is in a range from 5 to 85% per 2 cm
