Thermo-sensitive recording medium, thermo-sensitive recording device, and thermo-sensitive recording method for the same

摘要

A thermo-sensitive recording medium, a thermo-sensitive recording device, and a thermo-sensitive recording method for the same are provided. The medium includes a thermo-sensitive magnetic recording layer with a matrix resin, a first thermo-sensitive recording layer, a second thermo-sensitive recording layer, and a support layer. The matrix resin is heated to a temperature higher than the first development temperature to become fluid. The thermo-sensitive magnetic recording layer contains magnetic particles whose outer surfaces are colored with the first color dispersed in the matrix resin. The first thermo-sensitive recording layer is heated to a second development temperature to produce the second color. The second thermo-sensitive recording layer is heated to a third development temperature to produce the third color. The support layer supports the thermo-sensitive magnetic recording layer, the first thermo-sensitive recording layer, and the second thermo-sensitive recording layer.
