Abstract
Printing paper according to the present invention includes a base material and a coating layer disposed on the base material and being capable of receiving an oil-based ink, and the coating layer includes, in an upper portion thereof, an ink receiving layer containing a cationic polymer and being capable of receiving the water-base ink by allowing the water-based ink to penetrate into the ink receiving layer. When ejected onto the printing paper, the water-based ink penetrates into the ink receiving layer included in the upper portion of the coating layer and is received, so that bleeding of the water-based ink is suppressed. The printing paper can be manufactured at low costs without containing expensive materials such as inorganic fine particles. The surface condition of the coated paper for offset printing can thus be modified so as to be suitable for the water-based ink at low costs.
