Embodiment 1
[0039] The coating liquid A used the following composition. And the polyacrylic acid aqueous solution with a concentration of 7.5% was used as the gelling agent (and the contents of the components are all expressed as weight %).
[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.

[0058] The coating liquid B used the following composition. Moreover, the concentration of the gelling agent is 7.5% polyacrylic acid aqueous solution.
[0059] Composition of Coating Solution B
[0060] Colloidal silica: 71.4%
[0061] Plastic pigments: 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] Brightness (highest part): 86.3% ISO
[0069] Coating weight: 16.0g / m 2
[0070] Moisture: 6.2%

Abstract
A base paper 1 is coated with a cast-coating liquid with an air knife coater 2, then the cast-coating liquid is gelled by flowing an acid solution on a roll in a dipping coater 3, next the paper is passed through a nip 6 between a press roll 4 and a casting drum 5, and finally the base paper is pressed and dried with a heated mirror-finished casting drum 5. By employing a liquid including at least colloidal silica, plastic pigment, polyvinyl alcohol(PVA) and polydiallyldimethyl ammonium chloride (poly-Dadmac) as the cast-coating liquid, the photograph printing high gloss ink jet recording paper having the same or more degree of gloss obtained by the conventional two layers to be coated and excellent in jetting characteristics through only one layer to be coated is obtained.
Description
technical field [0001] The present invention relates to a cast-coated paper which has excellent surface gloss and can obtain high-quality photo printing quality, and is suitable for ink-jet printers, and more particularly relates to a high-gloss photo-printing paper manufactured according to the wet gelation method. Inkjet recording paper. Background technique [0002] Cast-coated paper is mineral pigment-coated paper generally having high surface gloss and smoothness, and is widely used as inkjet recording paper for printing photographs because of its excellent printing suitability. However, conventionally commercially available high-gloss inkjet recording paper for printing photographs has a disadvantage in that the production process is complicated because it has two or three coating layers. [0003] In addition, cast coatings that generally have high gloss have limited ink absorption due to the tight structure of the coating layer, which is unsuitable for inkjet printin...
