PURPOSE:To prevent excessive permeation or diffusion of a molten ink as in the case of a woodfree paper, by providing a coated layer comprising a specified lowly heat-conductive pigment on the surface of a raw paper, thereby providing micropores in an ink-receiving surface. CONSTITUTION:A coated layer comprising a pigment is provided at an ink- receiving surface of a recording paper in such a construction that a pigment selected from (A) an organic pigment having a thermal conductivity of a pigment constituting substance of not more than 0.3kcal/m.hr. deg.C, (B) an organic pigment having a thermal conductivity of secondary aggregate particles of not more than 0.3kcal/m.hr. deg.C and (C) an amorphous inorganic pigment having a thermal conductivity of secondary aggregate particles of not more than 0.3 kcal/m.hr. deg.C constitutes 30-100wt% of the pigment component in the coated layer, and the remainder of the pigment component is a crystalline inorganic pigment. With this construction, heat loss in a molten ink due to the coated layer is restrained, permeation of the ink into the coated layer is facilitated, and transfer of the ink through release from an ink ribbon is satisfactorily achieved with suppression of blurring on the coated layer. |
