Abstract:
An inkjet recording medium, comprising an ink-receiving layer containing a pigment, a binder and an inkjet ink-fixing agent comprising a cationic compound disposed on at least one surface of a base paper, wherein 50% or more by weight of calcium carbonate is contained in terms of a solid content based on a total amount of the pigment contained in the ink-receiving layer; 75 to 90 parts by weight of the pigment, 1 to 10 parts by weight of the binder and 5 to 20 parts by weight of the inkjet ink-fixing agent are contained based on 100 parts by weight of the ink-receiving layer; the drop water absorbency of the ink-receiving layer (according to the drop water absorbency defined in Japan Technical Association of the Pulp and Paper Industry, J. TAPPI, No. 32-2:2000 except that a drop water amount is 0.001 ml) is 200 seconds or less; and a Stockigt sizing degree according to JIS-P-8122 for the inkjet recording medium is 5 seconds or less.
