PROBLEM TO BE SOLVED: To efficiently transmit a heat-energy which is converted in a light- absorbing layer, to a transfer layer by providing a heat-insulating layer between a supporting layer and the light-absorbing layer. SOLUTION: On a supporting layer 21, a heat-insulating layer 24, a light- absorbing layer 22 and a transfer layer 23 are laminate in order. In this case, the heat insulating layer 21 is formed to have approx. the same thickness with the light absorbing layer 22, which is 1-20 μm, and it is especially preferable to be 3-4 μm. The heat-insulating layer 24 is constituted of a substance of which the thermal conductivity is lower compared with high molecules constituting the supporting layer 21 and the light-absorbing layer 22. By providing such a heat-insulating layer 24 between the supporting layer 21 and the light- absorbing layer 22, after an absorbed light energy is converted into a heat energy by the light-absorbing layer 22, a reverse transmission of the heat energy in the direction to the supporting layer 2 can be minimized. Therefore, the transmitting efficiency of the heat energy from the light-absorbing layer 22 to the transfer layer can be maximized. As a result, a transfer process can be made more efficient, and the quality of an image can be improved. |
