M334143 八、新型說明： 【新型所屬之技術領域】 本創作係有關一種合成紙技術，特別是一種防水喷墨海報用 之合成紙結構。 【先前技術】 一般辦公室用桌上型資料及圖片用之A4喷墨印表機與大型 之戶外海報用喷墨印表機之商品及技術都已趨成熟，其所使用之 耗材種類也相當繁多。然，所有耗材都須具備一種特性，就是耗 材表面必須對喷墨之墨水能快速吸收且不能暈開。 除影印紙利用纖維具有此種吸收特性外，其他耗材產品均依 賴塗佈一層吸墨層才能達到墨水之吸收。隨著印刷之品質、用 途、效果及單價需求不同，對於吸墨層之要求可區分為具防水 性、不具防水性，對於吸墨層之外觀亦可區分為亮面及霧面等不 同等級。耗材有從最便宜之模造紙與相紙到價格較高之各種塑膠 材料均有。 一般用於戶外海報之合成紙，於其喷墨後係於PP材質上不 防水之吸墨塗層上再上一層塑膠保護膜來達到防水效果。但此保 護膜之成本過高，因此目前已有多家合成紙塗佈廠商推出防水之 吸墨塗層以因應市場需要。 使用具防水之吸墨塗層材料可省去一道保護膜的成本與加 工程序。然目前防水產品耗材雖號稱具有防水性，但是效果不能 達完全防水且於喷墨後之墨水展色力也不理想。另外，此吸墨塗 層塗佈之生產速度慢，整體成本反而比不防水塗層產品加保護膜 之成本來的高。反而造成喷墨品質比不防水吸墨塗層材料差，且 其成本上也比不防水吸墨塗層材料具優勢。 5 M334143 因此，並不是市場不接受㈣水性之吸墨塗層材料之設計理 念，而是目前品質及價格尚未達到市場接受之鮮而造成銷量及 應用無法進一步提升。 目前在防水之吸墨塗層之配方上，多使用二氧化⑨卿㈣ 加陽離子固色劑以及加PVA系樹脂及相關助劑。由於pvA系樹 脂的使用會讓防水性無法達完全防水，且其固色效果不理想及生 產成本高。主要是因為PVA系樹脂配方之黏度較高，最低也須 1500 cps以上，導致生產速度無法提高，例如目前最高只能達 40〜50公尺/分鐘。因為PVA系水分較難加熱乾燥，容易有塗佈 品質瑕疵與塗層無法完全乾燥之問題，這是造成成本高之主因。 而且PVA之防水性較差，此配方塗層之防水性反而要靠防水助 劑反應來達成，因此無法達到完全防水效果。另外，於墨水吸收 性方面，除了二氧化矽外，PVA也幫忙吸收，反而造成過度吸收， 紙面喷墨後之色彩飽和度自然降低。 本創作主要就是利用配方系統之創新設計，來解決目前防水 之吸墨塗層所面臨之品質及價袼無法達到市場要求的問題。M334143 VIII. New description: [New technical field] This creation is about a synthetic paper technology, especially a synthetic paper structure for waterproof inkjet posters. [Prior Art] The products and technologies of the A4 inkjet printer for general office desktop data and pictures and the inkjet printer for large outdoor posters have matured, and the types of consumables used are quite numerous. . Of course, all consumables must have a characteristic that the surface of the consumable must absorb the ink quickly and not smudge. In addition to photopigmentation paper using fibers with such absorption characteristics, other consumable products rely on the application of an ink receptive layer to achieve ink absorption. As the quality, use, effect and unit price of the printing are different, the requirements for the ink absorbing layer can be classified as waterproof and non-waterproof, and the appearance of the ink absorbing layer can be distinguished into different grades such as bright surface and matte surface. Consumables range from the cheapest papermaking and photographic papers to the high-priced plastic materials. The synthetic paper generally used for outdoor posters is attached to a non-waterproof ink-absorbing coating on the PP material to provide a waterproof effect after being ink-jetted. However, the cost of this protective film is too high, so many synthetic paper coating manufacturers have introduced waterproof ink-absorbing coatings to meet market needs. The use of a water-repellent ink-absorbing coating material eliminates the cost and processing of a protective film. However, the current waterproof product consumables are said to be waterproof, but the effect is not completely waterproof and the ink color development after inkjet is not satisfactory. In addition, the production speed of the ink-absorbing coating is slow, and the overall cost is higher than that of the non-water-repellent coating product plus the protective film. On the contrary, the inkjet quality is worse than that of the non-waterproof ink-absorbing coating material, and its cost is also superior to that of the non-waterproof ink-absorbing coating material. 5 M334143 Therefore, it is not the market that does not accept the design concept of (4) water-based ink-absorbing coating materials, but the current quality and price have not yet reached the market acceptance, resulting in sales and applications cannot be further improved. At present, in the formulation of the waterproof ink-absorbing coating, the use of oxidized 9 qing (4) plus cationic fixing agent and the addition of PVA resin and related auxiliaries are often used. Due to the use of the pvA resin, the water resistance cannot be completely waterproof, and the fixing effect is not satisfactory and the production cost is high. Mainly because of the high viscosity of the PVA resin formulation, the minimum must be 1500 cps or more, which can not increase the production speed, for example, the current maximum can only reach 40~50 meters / minute. Since PVA is difficult to heat and dry, it is easy to have coating quality and the coating cannot be completely dried, which is the main cause of high cost. Moreover, the water repellency of the PVA is poor, and the water repellency of the coating of the formula is achieved by the waterproofing agent reaction, so that the complete waterproof effect cannot be achieved. In addition, in terms of ink absorption, in addition to cerium oxide, PVA also helps to absorb, but causes excessive absorption, and the color saturation after paper ink ejection is naturally reduced. This creation is mainly to use the innovative design of the formulation system to solve the problem that the quality and price of the current waterproof ink-absorbing coating cannot meet the market requirements.

Cree Benzene (10) copolymerization _, can provide complete waterproof two fruit. Ceremony, = creation = mesh = - provide - a kind of waterproof inkjet sea (four) synthetic paper knot ~, 7 ~ coating layer of the material including cationic acrylic. benzene b can be heart vinegar, can be used according to money silk, The ship is stepping on. The purpose of this creation is to provide a waterproof ink-absorbent coating layer. The material of the synthetic paper knot for waterproof inkjet posters includes a gram-styrene copolymerized resin, which is a 6 M334143 ink-absorbing coating layer. The formulated coating has a low viscosity, which can improve the coating speed in the manufacture of synthetic paper and relatively improve the compatibility of the coating equipment. In order to achieve the above object, a synthetic paper structure for a waterproof inkjet poster according to an embodiment of the present invention comprises: a polypropylene substrate; and an ink-absorbing coating layer applied to at least one of the polypropylene substrates. On the surface, the material of the ink-receiving coating layer comprises: _acrylic _ styrene copolymerized resin, a cationic fixing agent and a sulfur dioxide. [Embodiment] Fig. 1 is a view showing the structure of a synthetic paper for a waterproof inkjet poster according to an embodiment of the invention. In the present embodiment, the synthetic paper structure comprises: a polypropylene substrate 1; and an ink-absorbing coating layer 110. The ink-absorbing coating layer 110 is applied to one surface of a polypropylene substrate and then dried. The material of the ink-absorbing coating layer 11G includes - acrylic blister 4 copolymerized vinegar, a cationic fixing agent, cerium oxide and water. Following the above description, in the present embodiment, the material of the polypropylene substrate 100 is biaxially oriented polypropylene (BOPP), and a white foamed biaxially oriented polypropylene film may also be used. The polypropylene substrate (10) may be subjected to double corona treatment or flame treatment to increase the bonding effect with the ink receptive coating layer 110. In the meantime, the ink application layer 11 is absorbed. The coating method can be carried out by means of a bean-shaped scraper (c〇MMA) and a wire rod. The ink absorbing coating layer 110 has a coating viscosity range of about 5 〇〇 ^ s or less. Compared with the viscosity of the conventional PVA system coating formula, the coating speed can only reach 4〇~50 meters/min. The viscosity of the paint of the ink-absorbing coating layer of the present invention is relatively low, and the coating speed is greatly improved when the synthetic paper is produced. The cloth layer 11G towel makes acrylic benzene and benzene materials polymer tree to use water cation. Kenk force: benzene (four) find the purpose. The transfer temperature of the acrylic styrene wire is about 5 to 耽. Since the acrylic copolymer and the cationic solid-state are cationic, the effect of the fixing of the anionic ink is enhanced. M334143 In the present embodiment, the polypropylene substrate 100 has a thickness in the range of about 35 to 5 micrometers (μm). The dry film thickness of the ink-absorbing coating layer 110 ranges from about 10 to 5 μm. In one embodiment, the material of the ink-receiving coating layer 110 further comprises a color toner. Thus, the synthetic paper structure for the waterproof ink-jet poster has a basic background color for the user to select, and also reduces the printing process of the ground color. In addition, the paint viscosity of the ink-absorbing coating layer 11 of the present invention is relatively low. Therefore, the coloring material can be uniformly dispersed and the color is more uniform. In one embodiment, the ink-receiving coating layer may be disposed on both sides of the polypropylene substrate for double-sided printing of the synthetic paper. The same description will not be repeated here.
