For example, it is disclosed in JP-A-55-51583 that a coating layer comprising non-colloidal silica and a polymer binder is provided for high density printing, and 100 parts of an inorganic pigment is used to achieve high resolution printing. On the other hand, Japanese Patent Publication No. 61-60794 discloses that a recording paper containing 5 to 18 parts of an aqueous polymer adhesive and coated multiple times at 2 to 9 g / m 2 is used. In the latter case, the resolution can be improved by using the minimum amount of the adhesive and increasing the coating amount, but since the coating film strength decreases, the coating layer is divided into a plurality of coatings. Although it is dealt with by engineering, it is not sufficient for use in an environment where it is exposed to high humidity and water drops.

The support used in the present invention is a sheet-like support composed of a biaxially stretched multi-layered film containing a polyolefin containing an inorganic fine pigment as a main component.
Since it contains a thermoplastic resin as the main component, it has lower heat resistance than paper, and when used at a temperature above 120 ° C, the base material may shrink due to heat, which may cause problems such as curling. The drying temperature is preferably 120 ° C. or lower. In order to coat and dry the substrate under conditions in which heat shrinkage of the substrate is concerned, it is desirable that the coating layer be as thin as possible and that the heating temperature for drying be the minimum necessary.

Therefore, in order to make the total coating amount of the ink-receptive coating layer 8 to 20 g / m 2 , it is important to divide the ink-receptive coating layer into two layers to form the ink-receptive coating layer. The coating layer applied at one time is appropriately selected as necessary, but a coating amount of about ½ of the total coating amount of the ink-receptive coating layer is preferable. If the coating layer applied at one time is less than 1 g / m 2, it is not preferable because the coating film does not evenly cover the surface, and if it exceeds 10 g / m 2 , thermal influence on the substrate is caused. In a range not given, it is difficult to obtain a sufficient coating strength, and the image quality may be impaired due to the influence of minute bubbles during the preparation of the paint, which is not preferable.

When the coating amount of the laminated ink receptive coating layer is less than 8 g / m 2 , the ink absorption capacity of the heavy color portion in color printing is insufficient. Further, if it exceeds 20 g / m 2 , the effect is saturated and the cost is increased, which is not preferable.

As is clear from Table 1, according to the present invention, 50 to 80% by weight of amorphous finely divided silica, 10 to 30% by weight of an aqueous adhesive and 2 to 20% by weight of a cationic polymer are used. An ink receptive coating layer containing as a main component, and a polyolefin containing an inorganic fine pigment as a main component,
Two or more coating layers are laminated on at least one surface of a sheet-like support made of a film having an axially stretched multilayer structure to form an ink-receptive coating layer, and the ink-receptive coating layer is 8
By adopting each technical matter of coating at a rate of up to 20 g / m 2 , the print density and print quality of the image by inkjet recording are good, the surface receptivity of the ink-receptive coating layer is excellent, and the processability is good. It is possible to obtain a water-based inkjet recording sheet having good image quality and satisfying the water resistance and moisture resistance of the image and the substrate (Examples 1 to 1).

On the other hand, amorphous silica is 50% by weight.
If it is less, the ink absorbency is lowered, the sharpness and the drying property after printing are lowered, and if the amount of amorphous silica is more than 80% by weight, the strength of the coating film is lowered. If the amount of the water-based adhesive is less than 10% by weight, the strength of the coating film is lowered, and if it is more than 30% by weight, the ink absorbency is lowered.

Further, if the amount of the cationic polymer is less than 2% by weight, the water resistance of the printed matter is lowered. (Comparative Examples 1 to
3). In addition, if the ink-receptive coating layer is manufactured as a single layer, the strength of the coating film decreases, and even if two layers are laminated, the coating amount is 8
If it is less than g / m 2 , the ink absorbency is lowered, the drying property is insufficient, and the sharpness of printing is lowered (Comparative Example 4 to
5). When a paper base material is used instead of a sheet-like support made of a biaxially stretched multi-layered film whose main component is a polyolefin containing an inorganic fine pigment as a base material, the water resistance of the inkjet recording sheet is insufficient (Comparative Example 6). ).
