Abstract
A method for manufacturing an inkjet recording medium comprising the steps of: applying a coating color containing a pigment and a binder as major components to at least one side of a base material using a transfer roll coater, subsequently drying coating layer to form an ink absorbing layer, wherein Hercules viscosity of coating color is 5 m Pa·s to 30 m Pa·s and pigment contains a synthetic silica having an oil absorption of 90 ml/10 g to 200 ml/100 g, a BET specific surface area of 45 m/g to 200 m/g and an average particle diameter of 1.0 μm to 3.0 μm and/or a precipitated calcium carbonate-silica composite having an oil absorption of 100 ml/10 g to 250 ml/100 g, a BET specific surface area of 5 m/g to 150 m/g and an average particle diameter of 1.0 μm to 10 μm.
