PROBLEM TO BE SOLVED: To provide an OHP sheet which is not damaged on a rear surface of a sheet in the case of supplying a continuous sheet as a material to be recorded used for an ink jet printer having a so-called friction pad type separator for feeding a sheet in the state that the materials are separated one by one by a sheet supply roll and a separate pad. SOLUTION: A material to be recorded has physical properties in which static frictional coefficients of a printing surface and its rear surface to be brought into contact with one another are 0.08 to 0.3, a surface hardness measured by a Vickers hardness test (a load of 10 g) is 15 to 25 on a printing surface and 10 to 20 on a rear surface, a difference of surface roughnesses of the printing surface and the rear surface measured by a PPS(Parker print surface) type is 5 to 10 μm, and a Clark relative stiffness is 50 to 130 cm<2> /100. |
