Description of the Invention (7) Heavy calcium carbonate is wet-milled in the presence of the above-mentioned cationic copolymer dispersant. More specifically, S 'is to add an aqueous medium (preferably water) to the particles of the heavy carbonic acid. The method is to obtain a weight ratio of heavy calcium carbonate / aqueous medium of 70/30 to 30/70. 60/40 to 40/60. Then, a cationic polymer dispersant is added thereto in an amount of 0.05 to 2 parts by weight, preferably οm to 1 part by weight, and the calcium carbonate is 100 weight parts per 100 parts by weight. The dry matter is the 'view. Next, the obtained mixture was wet-milled in a conventional manner. Alternatively, the cationic copolymer dispersant is first dissolved in an aqueous medium to obtain the ratio as specified above, and then mixed with the heavy carbonic acid sentence, followed by wet milling in a conventional manner. Wet milling can be carried out batchwise or continuously. It is preferred to use a mill having a grinding medium, such as a sand mill, an ultrafine mill, or a ball mill. Therefore, calcium carbonate particles having an average particle size of 2 µm or less, preferably 0.3 to 2 µm can be obtained. Then, the wet-milled product was dried. The wet-milled particles can also be classified, so the coarser ones (the ones on the 35 mesh) are excluded from them before drying. Drying can be performed by known methods, such as hot air drying or spray drying. Among them, the drying method of the fluid medium is preferable. In the fluid media drying method, a slurry substance is fed into a fluidized media particle (fluidized bed) via a stream of hot air. Therefore, the slurry material thus supplied is adhered to the surface of the fibrous fluidized medium particles β in a thin film state, so that the material is dispersed in the fluidized bed and dried by a stream of hot air therein. Therefore, the fluid medium drying operation can be easily performed using, for example, a medium slurry dryer manufactured by Nar ^ magic Seisgkush0 κ κ. It is preferred to use such a media fluid dryer because the material can be dried and processed into primary particles at the same time. —_-____ -10 ^ This paper size is applicable) Α4 size (2 丨 Gx297 male Chu 1 ~~ '— --- / 谙 Xian'M Please note on the back ^ this page) Pack-丁 4 ° ik * & lt U3225 V.

However, after the fluid media drying is completed, the particles can be further ground and classified by any desired method. When the wet-milled product is not dried by the fluid media drying method, but by drying with hot air, it is recommended that The filter cake thus obtained is further ground and classified by any desired method.-The dry filter cake of the wet-milled product thus obtained is easily broken, so fine calcium carbonate particles can be easily obtained therefrom without grinding the dry filter cake.

(2) In a thermostatic chamber (23 ° C, RH 50%), collect the above ink with a syringe, and drop the appropriate amount on the surface of the synthetic paper obtained in Examples Π. To 20 and Comparative Examples 7 to 13. To obtain a droplet area of 2 mm in diameter. After the dropwise addition, the contact angle was measured using CONTACT-ANGEL METER? M (manufactured by Kyowa Kaimenkagaku K.K.). Tables 3 and 4 show the data thus obtained. &lt; Printability of inkjet inks &gt; ⑴ Drying time (seconds) Using inkjet printer BJC-410J (manufactured by Canon), the synthetic papers obtained in Examples η to 20 and Comparative Examples 7 to 13 were made using watercolor. The inkjet recording liquid BCI-21 (yellow, magenta, cyan 'black) is used for color printing. Then, the time required for the parts printed in various colors to be rubbed with fingers without causing traces is called the drying time. ⑺ Fluidity The fluidity of various color inks printed under the above conditions was evaluated with the naked eye according to the following criteria. , Ό: No color flow was found. 〇: Slight flow is found in specific colors, which will not cause -33 in practical use. This paper size applies the Chinese Garden Standard (CNS) A4 specification (2Ι0 × 297). 41 ^ 41 ^ Yin Zemu A7 B7, Consumer Cooperative of Employees' Cooperatives of the Central Bureau of Standards of the Ministry of Economy and Economics 5. Explanation of the Invention (31)-Question. △: Flow is found in various colors, but it is practically unusable. X: Severe flow was found on various colors. (3) Image quality Use the same printer and recording solution to print portraits, and evaluate the image quality with the naked eye according to the following criteria. :: Good. 〇: The ink density is slightly lower, which does not cause a problem in practical use. △: Due to the low ink density and ink flowability, it is practically unusable. X: Defective. &lt; Ink Residue Properties on Inkjet Printing &gt; Next, the adhesive tape &quot; Cell〇tapeT M &quot; (manufactured by Mchiban) was strongly adhered to a part of each printing paper, and then quickly peeled off along the adhesive surface. . Tables 3 and 4 show the inks left on the synthetic paper. &lt; Drying properties of water-based adhesive &gt; The synthetic papers obtained in Examples 11 to 20 and Comparative Examples 8 to 14 were cut into pieces (8 X 8 cm). Then, a starch adhesive 600TM (solid content: 33%, manufactured by Tokiwa Kagaku K.K.) was uniformly applied on the surface thereof using a liquid applicator to obtain a thickness of 10 µm. The time it takes for the gloss of the adhesive to disappear is called the drying time. This gloss disappears because its moisture penetrates into the paper. The present invention makes it possible to provide a synthetic paper with finely milled calcium carbonate particles protruding, the particles having a hydrophilic surface, and forming a plurality of __ __-34-This paper is compliant with the Zhongjia standard (Λ4 specification (210 &gt; &lt; 297 公 漦) '——-{Please read the notes on the back ^^ write this page first).-° 418225 A7 B7 V.
