PURPOSE:To impart high density sharp printing, by a method wherein the heat- meltable material of a first ink layer constitutes a group of one kind of heat- meltable resin fine particles and the heat-meltable material of a second ink layer form two or more kinds of domains. CONSTITUTION:In a first ink layer 3, a heat-meltable material constitutes a group of one kind of heat-meltable resin fine particles 5 and the content of polyethylene oxide being the component of the fine particles is pref. 50wt% or more and further pref. 70wt% or more. In a second ink layer 4, for example, two or more kinds of domains are constituted of an appropriate combination of heat-meltable resin fine particles and a non-particulate phase. In the second ink layer, the flocculation force in the ink layer is made small to a large extent as compared with a uniform system. The heat meltable material of the first ink layer controls the adhesive strength to a support to a gentle state regardless of the magnitude of the flocculation force of polyethylene oxide in fine particles and can form an ink layer having weak flocculation force. By this method, good printing is formed. |
