Problems solved by technology

[0006]However, the inkjet recording medium composed of resin-coated paper coated with an ink-accommodating layer mainly composed of alumina is not suitable for printing in inkjet printers. , Wrinkles (fluctuation of the printing surface) and curling (curving of the printing surface) are generated due to the application of ink, and there is a problem that paper jams are easy to occur, and the recording medium contacts the recording head of the printer and the recording head is scratched.
Recording head scratches can not only stain the recording media, but in the worst case can damage the recording head
In addition, when deformation of the recording medium such as wrinkles and curls occurs, even if the image quality itself is high-quality, the appearance and texture of the printed matter as a whole will be significantly reduced, and as a result, high-quality printed matter cannot be obtained.

Embodiment 1

[0067] 0.5 parts by weight of epoxidized behenamide, 1.0 parts by weight of anionic polyacrylamide, and 0.1 parts by weight of polyamide polyamine epichlorohydrin are added to 100 parts by weight of LBKP pulp with a beating degree of 300mlcsf in an absolute dry weight ratio relative to the pulp. , 0.5 parts by weight of cationic polyacrylamide to obtain slurry, which is made into 170g / m by fourdrinier paper machine 2 base paper. And, in order to adjust the surface size of the base paper, 0.04% by weight of a fluorescent whitening agent (Sumitomo Chemical Industry, Whitex BB) was added to a 4% aqueous solution of polyvinyl alcohol, and it was soaked into the base paper so that the absolute dry weight converted into 0.5g / m 2 , after drying, further apply calendering treatment to adjust the density to 1.05g / ml to obtain a base paper with a thickness of 150μm.

Embodiment 2～4 and comparative example 2～4

[0075] In Example 1, except that the base paper constituting the resin-coated paper and the thickness of the resin layer (resin layer on the ink storage layer coating side, resin layer on the ink storage layer non-coating side) were adjusted as shown in the following (Table 2) Except for various modifications, the same inkjet recording media as in Example 1 were produced, and they were used as samples of Examples 2 to 4 and Comparative Examples 1 to 4, respectively.

Embodiment 5

[0089] Coating liquids for an upper layer and coating liquids for a lower layer having the following compositions were prepared, respectively. Then, on the above-mentioned anchor coating layer of the resin-coated paper used in Example 1, the coating liquid for the lower layer was coated and dried so that the coating amount after drying was 10 g / m 2 , further, apply and dry the coating liquid for the upper layer, so that the coating amount after drying is 30 g / m 2 . In this manner, an ink storage layer having a two-layer structure composed of a lower layer with a thickness of 10 μm and an upper layer with a thickness of 30 μm laminated in this order was coated on the resin-coated paper.

[0090] The inkjet recording medium obtained by the above procedures was used as a sample of Example 5.

Abstract

Disclosed is an ink-jet recording medium comprising: a resin-coated paper which comprises a base paper and resin layers applied on both surfaces of the base paper; and an ink-receiving layer applied on one of the resin layers, wherein the ink-receiving layer contains an inorganic particle and a binder for the inorganic particle and the inorganic particle is made of alumina. In the ink-jet recording medium, the base paper has a thickness of 100 to 300 mum, and the thickness ratio between the resin layer provided between the base paper and the ink-receiving layer and the other resin layer is 1:1 to 1:2.

Description

technical field [0001] The present invention relates to a recording medium for inkjet recording, and more particularly to an inkjet recording medium capable of providing high-quality printed matter and having excellent transportability to a printer. Background technique [0002] The inkjet method refers to a printing method in which droplets of ink are discharged from nozzles provided in a recording head, and the ink is attached to a recording medium such as paper to record an image. Existing high-grade paper or coated paper can be used as the inkjet recording medium, but in order to obtain high-quality printed matter comparable to silver halide photographs, it is necessary to use paper that can handle a large amount of ink discharge and has better ink absorption. Excellent recording medium. Therefore, as an ink-jet recording medium with excellent ink absorbability, a medium formed by coating a carrier with a coating layer having a void structure, a so-called void-type ink ...
