PURPOSE:To wholly erase the impression so that all the adhesives of a colouring layer never remains in an acceptor, by a method wherein an ink layer has a colouring layer on the base side, an adhesive layer on the surface side and the separation layer, of which fusion viscosity under heating by a printing head is lower than those of the other layers, between both the layers. CONSTITUTION:An ink layer has a colouring layer on the base side, an adhesive layer on its surface side and the separation layer of which fusion viscosity under heating by a printing head between both the layers. The colouring layer is so regulated that its viscosity at 110 deg.C is not less than 1X10 poise and higher than the viscosity of the separation layer by not less than 1X10 poise. The materials consisting of the separation layer, are composed of the resin and (or) wax which are fused or softened at 50-200 deg.C. The viscosity at 110 deg.C of the adhesive layer is within a range of 1-8X10 poise and higher than that of the separation layer by not less than 1-3X10 poise and adhesive to the acceptor. |
