PURPOSE:To enable high-resolution high-density printing, by providing an ink layer with a coloring agent concentration which increases with the distance from a base film. CONSTITUTION:A heat-fusible ink layer 2 in which the concentration of a coloring agent at a point is greater as the point is nearer to the surface of the layer is provided on one side of a base film 1. The ink layer 2 is provided by superposingly applying a plurality of ink layers 2, of which the first one 2a has a comparatively lower coloring agent concentration, and the following ones 2b, 2c have progressively higher coloring agent concentrations, whereby the concentration of the coloring agent in the resultant ink layer 2 can be given a gradient. It is thereby made possible to achieve uniform printing with high density and to enhance resolution. |
