AI Technical Summary

Problems solved by technology

However, the particle size of the silica dispersion prepared using a dispersing machine such as a ball mill or a sand mill is large, and the dispersion is also relatively opaque
Therefore, the inkjet recording medium using this dispersion liquid cannot obtain sufficiently satisfactory glossiness

Embodiment 1

[0293] -Preparation of carrier-

[0294] 50 parts of maple kraft pulp (LBKP) and 50 parts of locust wood kraft pulp (LBKP) were beaten separately by a double disc refiner to obtain a pulp slurry with a Canadian freeness (Canadian standard freeness) of 330 ml.

[0295] Then, 1.3% of cationic starch (trade name: CATO 304L, produced by Nippon NSC, Ltd.), 0.15% of anionic polyacrylamide (trade name: DA4104, produced by Seiko PMC (k.k.)) were added to each pulp , 0.29% alkyl ketene dimer (trade name: SIZE PINE K, produced by Arakawa Chemical Industries, Ltd.), 0.29% epoxidized behenamide and 0.32% polyaminopolyamine epichlorohydrin (trade name: ARAFIX 100, produced by Arakawa Chemical Industries, Ltd.) was added to the resulting pulp slurry, and then 0.12% of an antifoaming agent was also added.

[0296] The pulp slurry prepared as described above was passed through a fourdrinier paper machine where it was dewatered and dried to produce paper with a basis weight of 200 g / m 2 and ...

Embodiment 2

[0335] Carrier B was prepared and an inkjet recording sheet according to the present invention was also prepared in the same manner as in Example 1, except that the Canadian freeness after beating the pulp by a double disc refiner was changed from " -Preparation of carrier A-" in "330ml was changed to 280ml.

Embodiment 3

[0337] Carrier C was prepared and an inkjet recording sheet according to the present invention was also prepared in the same manner as in Example 1, except that the thickness of the thermoplastic resin layer on the "front surface" was changed from that of "-Carrier A" in Example 1 to The 40 μm in “Preparation-” was changed to 50 μm.

Abstract

An ink jet recording medium comprising a substrate and at least one ink-receiving layer on the substrate, wherein said ink-receiving layer after recording has the characteristic that the sum of image clarity values is 130 or more (when measured by optical combs of 0.125 mm, 0.25 mm, 0.5 mm, 1.0 mm and 2.0 mm) and the regular reflection strength is 30 or more, makes it possible to record a high quality image which has high glossiness and photographic feel.

Description

technical field [0001] The present invention relates to an inkjet recording medium, and more particularly, to an inkjet inkjet suitable for recording high-quality images with high gloss and photo feel (for example, photo glossy paper for inkjet printers) recording medium. Background technique [0002] From the viewpoint that recording can be performed on various recording materials, hardware (apparatus) is relatively inexpensive and compact, and is excellent in terms of noiselessness, the inkjet recording method is widely used. With the recent development of high-resolution inkjet printers, hardware (devices) and various inkjet recording media, so-called "photographic" high-quality images have become possible. [0003] As an inkjet recording medium, a recording material having high gloss and color saturation and good ink absorption is required from the viewpoint of improving the photographic feel. In order to satisfy these characteristics, ultrafine particles having an ave...
