Embodiment 1

[0039] The coating liquid A used the following composition. In addition, a polyacrylic acid aqueous solution with a concentration of 7.5% was used as the gelling agent (and the content of the components is all expressed as weight%).

[0040] Composition of coating solution A

[0041] Precipitable silica (particle size 12μm): 12.2%

[0042] Colloidal silica: 61.0%

[0043] Plastic pigment: 6.1%

[0044] SBR latex: 4.9%

[0045] PVA: 3.0%

[0046] poly-Dadmac: 11.0%

[0047] Polyethylene wax: 1.5%

[0048] Gloss aid (OBA): 0.3%

[0049] Total: 100%

[0050] The measurement results of the cast paper obtained using this coating liquid A are as follows.

[0051] White gloss (Sheet Gloss): 85%

[0052] Gloss (highest part): 90.4%ISO

[0053] Coating weight: 18.2g / m 2

[0054] Moisture: 5.1%

[0055] In addition, the results of the inkjet test obtained are shown in Table 1.

[0056] Types of inkjet test

Embodiment 2

[0058] The coating liquid B used the following composition. In addition, the gelling agent is used at a concentration of 7.5% polyacrylic acid aqueous solution.

[0059] Composition of coating solution B

[0060] Colloidal silica: 71.4%

[0061] Plastic pigment: 10.7%

[0062] PVA: 3.6%

[0063] poly-Dadmac: 10.7%

[0064] Polyethylene wax: 3.6%

[0065] Total: 100%

[0066] The measurement results of the cast paper obtained using this coating liquid B are as follows.

[0067] White gloss (Sheet Gloss): 79%

[0068] Luminance (highest part): 86.3%ISO

[0069] Coating weight: 16.0g / m 2

[0070] Moisture: 6.2%

[0071] In addition, the results of the inkjet test obtained are shown in Table 2.

Abstract

In this invention, after the base paper (1) is coated with the cast coating solution by the air knife coater (2), the acidic solution flows to the roller at the dip coater (3) to gel the cast coating solution, and then passes through the pressure roller (4) and the roll gap (6) between the casting drum (5), so that it is pressed against the heated mirror-like casting drum (5), and it is completed after drying. Since a coating solution containing at least colloidal silica, plastic pigments, polyvinyl alcohol (PVA) and polydimethyldiallyl ammonium chloride (poly-Dadmac) is used, only one layer of coating layer, it is possible to obtain the same or better characteristics of the existing high-gloss inkjet recording paper for photo printing with two coating layers, that is, it has gloss and excellent inkjet characteristics at the same time.

Description

Technical field [0001] The present invention relates to a cast-coated paper suitable for inkjet printers with excellent surface gloss and high-quality photo printing quality. More specifically, it relates to a high-gloss printing photo-printing paper manufactured according to a wet gel method. Paper for inkjet recording. Background technique [0002] Cast-coated paper is mineral pigment-coated paper that generally has high surface gloss and smoothness. Because of its excellent printing adaptability, it is commonly used as inkjet recording paper for printing photographs. However, the high-gloss inkjet recording paper for printing photographs on the market in the past has the disadvantage that the manufacturing process is complicated because it has a two-layer or three-layer coating layer. [0003] In addition, usually high-gloss cast coatings, due to the compact structure of the coating layer, have limited ink absorption, and therefore have an unsuitable aspect as inkjet printing ...
