PURPOSE:To provide a clean image by applying heat energy in a short time and to improve various rigidity of an image formed in this manner by mainly varying the composition of a resin binder and a dye or their combination of a dye carrying layer formed on a base sheet. CONSTITUTION:A varying method for the composition of a dye carrying layer preferably includes a method for composing two or more dye carrying layers, such as, for example (1) a method of firstly forming a first layer of relatively high concentration with ink or paint for forming the layer having large dye concentration on a base sheet, and then forming a second layer of relatively lower concentration that the first layer on its surface, (2) a method for varying a resin binder of a dye carrying layer (first layer) near a base sheet and of a dye carrying layer (second layer) near a surface, and (3) a method for using dyes of different heat transfer properties between the first and second layers when the resin binders of the first and second layers are similar. The dye carrying layers formed in this manner are approx. 0.4-2.0mum thick as a whole, and the heat transfer able dyes in the layer are preferably 10-60wt% of the weights of the layers. |
