PROBLEM TO BE SOLVED: To improve ink mileage, and removability of silicone rubber layer, that is a developability by incorporating at least a photothermal converting agent, a foaming agent, and thermoplastic resin. SOLUTION: A black pigment such as carbon black and a green pigment such as phthalocyanine for a photothermal converting agent. Except these substances, all dyes can be used, which have a maximum absorption wavelength in the range of 400-1200 nm. A content of photothermal convertion substances is 0.1-40 wt.%, preferably, 0.5-25 wt.% based on the composition of all thermosensitive layer. As a foaming agent, there are used heat foaming resin grains. A content of the foaming agent is 0.1-50 wt.%, preferably, 0.5-20 wt.% based on the composition of all thermosensitive layer. As a thermoplastic resin, phenol resin, polyurethane, or the like are used in particular. The content of the thermoplastic resin is 5-95 wt.% based on the composition of all thermosensitive layer. |
