PURPOSE:To improve adhesion between a heat sensitive coloring layer and a base and to enable always sharp images to be recorded, by providing a resin adhesive layer between the heat sensitive coloring layer and the base. CONSTITUTION:A 1-20 wt.% polymer solution obtained by dissolving in a proper organic solvent an adhesive resin material, such as polyvinyl-butyral is coated on base 1 made of an organic polymer sheet and dried to form a resin adhesive layer 2 having a dried attachment thickness of 1-10mu. Then, a heat sensitive coloring substance and a proper binder are dissolved or dispersed, coated on layer 2, dried below the coloring temperature to form a heat sensitive coloring layer 3 having a dried attachement thickness of 1-10mu. |
