PURPOSE: To easily obtain good tensile strength and elastic modulus by incorporating at least one kind of thermotropic liquid crystal polymer into a layer supporting body. CONSTITUTION: At least one kind of liquid crystal polymer is incorporated into a flexible layer supporting body in a tape form. Namely, the layer supporting body to produce a recording material substantially consists of one or more thermotropic polymers, preferably a liquid crystal polyester. Therefore, the strength, elastic modulus and toughness of the recording medium can be improved, the uniformity and cleaning property of the layer supporting body can be substantially improved, and the wear resistance can be increased. Moreover, necessary coating can be applied in the on-line process by using a cast forming device just after the layer supporting body is formed. |
