Japanese Patent Publication No. 53-6243 discloses a method of producing a watermark pattern by coating a base paper with a paint containing a white pigment and the like, but when printing with an ink jet printer, the absorbency is poor. However, there was a problem such as bleeding in the printing section, and it could not be used as an inkjet recording paper. Further, Japanese Patent Publication No. 63-151476 discloses a method of changing the surface condition of an ink jet recording paper by superposing transfer sheets having a desired surface condition in a semi-dried state when a coating layer is provided on the surface of a support. However, there is a problem that the process is complicated and it is not possible to deal with complicated surface conditions (for example, complicated uneven pattern).

The coating amount of the ink absorptive coating layer obtained in the present invention is determined by the end use and does not need to be unnecessarily increased as long as the ink absorptivity, recording characteristics, storability, etc. are satisfied. It is used by appropriately selecting from the range of 20 g / m 2 . If the ink-receptive coating layer is less than 3 g / m 2 , the ink absorption capacity is insufficient in many cases, and the image runs out, color bleeding occurs, the image becomes blurred, the drying is slow, and the ink adheres to the roll. It gets dirty. However, when an ink-receptive coating layer having a coating amount of more than 20 g / m 2 is provided, the coating layer is thick and the adhesion to paper becomes weak,
Problems such as clogging of the head nozzle often occur, and the cost becomes high.
