PURPOSE:To obtain an ink jet recording paper which is excellent in the ink-absorbing property and restrains spread of an ink dot, by allowing said paper to contain polyvinyl pyrrolidone or polyvinyl pyrrolidone-vinyl acetate copolymer as a surface sizing agent or a binding agent for coating. CONSTITUTION:To an aqueous solution containing polyvinyl pyrrolidone or polyvinyl pyrrolidone-vinyl acetate copolymer as a surface sizing agent or a binding agent for coating, a white pigment and a filler (example: talc or clay) is added to form slurry, which is applied to paper. Thereby, it is possible to obtain an ink jet recording paper which restrains spread an ink dot and can keep the recording density of a recording material high. |
