PURPOSE:To prevent the generation of the so-called ghost such that the previous printing pattern is raised in a printing body on and after the second time by adding a non-heat-meltable particle to an ink layer. CONSTITUTION:As the non-heat-meltable particle contained in an ink layer, an inorg. particle such as a titanium oxide particle, a magnesium oxide particle or a metal powder and an org. particle mainly composed of a thermosetting resin such as a polystyrene resin or a benzoguanamine resin are designated. The particle may have any shape, but a spherical particle is pref. used and the pref. particle size thereof is 4 - 20 mum and the addition amount thereof is pref. 5 - 40 vol. % with respect to the total amount of heat-meltable ink. The ink layer is formed on a support by applying the components forming the ink layer on the support by a hot melt method or a solvent coating method. |
