Summary:PROBLEM TO BE SOLVED: To improve fine line reproducibility or the like by incorporating a thermoplastic resin and a compound having a polyoxyalkylene chain in an ink layer. SOLUTION: An ink layer contains a coloring agent and a thermoplastic resin as main components, and further contains a compound having a polyoxyalkylene chain. In this case, as the agent, for example, an inorganic pigment (titanium dioxide or the like), organic pigment (azo or the like), or dye (acidic or the like) is used. As the thermoplastic resin, an ethylene copolymer or the like can be exemplified. In the ink layer, a compound having a polyalkylene chain of 1 to 30 pts.wt. is added. The polyalkylene chains of the compound are preferably 4 to 50. As a photothermal conversion substance used for a photothermal conversion layer, in the case of using a semiconductor laser, as a near infrared absorbent, for example, a thioamide organic metal complex or the like is preferred.
