Since it is not possible to use only low-boiling solvents with high volatility in the mixing, more than 20% by weight must be used. High boiling point solvents are mixed. When the high-boiling-point solvent exceeds 250% by weight, the mobility of the magnetic particles is deteriorated.
本發明中，前述（1 )中記載的微膠囊平均粒徑為3 0 〜170//m，優選40〜150//m，更優選50〜130//m。在本發 明中，由於平均粒徑在3 0〜1 7 0 // m的範圍，無論筆記用磁 鐵或消除用磁鐵的種類如何都可記錄鮮明的文字等，並乾 淨地消除，不但非常容易看見黑白反差清晰的筆記物，而 且可製作成薄型微膠囊磁性記錄板。 前述（2)中記載的固態分散層的厚度為50〜 3 6 0 // m 5優選50〜300//ΙΠ，更優選60〜250//m。如果該厚 度不足5 0 // m，顯示畫像的對比度變得非常不鮮明，另 外，如果超過360//ΙΠ，在作為薄型的用途中會帶來障礙， 因此不是優選的。另外，本發明中，微膠囊磁性泳動顯示 板總厚度在7 0 0 // m以下，如果超過此厚度，不能在作為薄 型的用途中使用。另外，該下限與固態分散層的厚度基本 相同。In the present invention, the average particle size of the microcapsules described in the above (1) is 30 to 170 // m, preferably 40 to 150 // m, and more preferably 50 to 130 // m. In the present invention, since the average particle diameter is in a range of 30 to 17 0 // m, it is possible to record sharp characters and the like regardless of the type of the magnet for writing or the magnet for erasing, and to eliminate it cleanly, which is not only easy to see Black and white contrast notes, and can be made into a thin microcapsule magnetic recording board. The thickness of the solid dispersion layer described in the above (2) is 50 to 3 6 0 // m 5, preferably 50 to 300 // ΙΠ, and more preferably 60 to 250 // m. If the thickness is less than 5 0 // m, the contrast of the displayed image becomes very unclear, and if it exceeds 360 // ΙΠ, it may cause obstacles in the use as a thin type, so it is not preferable. In addition, in the present invention, the total thickness of the microcapsule magnetic swimming display panel is less than 7 0 // // m. If it exceeds this thickness, it cannot be used for thin applications. In addition, this lower limit is substantially the same as the thickness of the solid dispersion layer.

The support may be transparent or opaque, but when viewed directly, a transparent substance is used. As such a transparent plate, polyester films such as polyethylene terephthalate, polyethylene film, polypropylene film, vinyl chloride film, and polycarbonate film can be preferably used. It is not limited to these, and a polyethylene terephthalate film is preferable.

本發明中，可在固態分散層的裏面（與支援體相對的 表面側）設有1 0〜2 0 0 // m的保護層，具體的說，這些保護 層可使用前述的聚酯樹脂，例如聚對苯二甲酸乙二醇酯， 聚乙烯樹脂，聚丙稀樹酯，氣化乙稀樹脂，聚碳酸自旨樹 脂，紫外線硬化性樹脂等透明或非透明樹脂塗布或將這些 形成的薄膜用接合劑或粘合劑接合。也可以向這些薄膜以 外的紙、鋁箔、橡膠層等接合。如果從製造效率上講，優 選使用樹脂塗布，乾燥。保護層的作用效果，由於緩和對 微膠囊局部的壓力，因此可防止微膠囊的破壞。緩和對微 膠囊局部的壓力是指，相對於筆記壓力，透明薄膜層，不 會凹陷，不會損傷，同時不會損壞其彎曲性。因此，透明 薄膜層的硬度可根據調整該透明薄膜的樹脂硬度的方法和 該透明薄膜層樹脂硬度所規定的使用產物的厚度進行調 整。In the present invention, a protective layer of 1 to 2 0 0 // m may be provided inside the solid dispersion layer (on the surface side opposite to the support). Specifically, the aforementioned polyester resin may be used for these protective layers. For example, transparent or non-transparent resins such as polyethylene terephthalate, polyethylene resin, polypropylene resin, vaporized ethylene resin, polycarbonate resin, ultraviolet curable resin, etc. Adhesive or adhesive bonding. It may be bonded to paper, aluminum foil, rubber layer, etc. other than these films. In terms of manufacturing efficiency, resin coating and drying are preferred. The effect of the protective layer is to relieve the local pressure on the microcapsules, thereby preventing the destruction of the microcapsules. Relieving the local pressure on the microcapsules means that the transparent film layer will not sag, will not be damaged, and will not damage its flexibility compared to the pressure on the note. Therefore, the hardness of the transparent film layer can be adjusted according to the method of adjusting the resin hardness of the transparent film and the thickness of the product to be used which is specified by the resin hardness of the transparent film layer.
本發明中，在固態分散層的表面設有作為保護層的薄 膜（或片層）時，優選用接合劑（這裏，用語接合劑，包 含粘合劑的意思）將薄膜貼附。作為這裏使用的接合劑， 沒有特別的限制，可使用廣泛種類的接合劑或粘合劑。例 如，在天然橡膠，聚氨酯類樹脂，丙烯酸類樹脂，異戊橡 膠，苯乙烯丁二烯橡膠，苯乙烯丁二烯嵌段共聚物，苯乙 烯異戊二烯嵌段共聚物，丁基橡膠，聚異丁烯，矽橡膠， 聚乙烯基異丁基醚，氣丁二烯橡膠，丁腈橡膠，接枝橡 膠，再生橡膠等彈性體中加入接合劑，軟化劑，防老化 劑，填充劑等後而製作。通常優選天然橡膠類，苯乙烯丁 二烯類，聚異戊二烯類，丙烯酸類，矽橡膠類等各種接合In the present invention, when a thin film (or sheet) as a protective layer is provided on the surface of the solid dispersion layer, the film is preferably adhered with a bonding agent (herein, the term bonding agent includes an adhesive). The adhesive used here is not particularly limited, and a wide variety of adhesives and adhesives can be used. For example, in natural rubber, polyurethane resin, acrylic resin, isoprene rubber, styrene butadiene rubber, styrene butadiene block copolymer, styrene isoprene block copolymer, butyl rubber, Polyisobutylene, silicone rubber, polyvinyl isobutyl ether, gas butadiene rubber, nitrile rubber, graft rubber, recycled rubber and other elastomers are added with bonding agents, softeners, anti-aging agents, fillers, etc. Production.

該接合劑層的厚度，在保護微膠囊的同時，從消除已 描繪記錄是否良好的關係上看，當然是不要太厚，在所謂 薄型板的限制下也不能太厚。因此接合層的厚度優選為1 0 〜1 8 0 // m。更優選為3 0〜1 3 0 // m。該接合劑層，不僅將薄 膜和固態分散層接合，而且防止了微膠囊被覆層中的微膠 囊被筆記中的壓力破壞，因此可長時間顯示鮮明的文字或 畫像，並使得微膠囊磁性顯示板成為有優良的耐久性的產 品。即，接合層的厚度比1 0 // m薄時，對微膠囊的保護不 充分，由於筆記錄中的壓力有可能使微膠囊被破壞。另 外，其厚度超過1 8 0 // m時，雖然可得到充分的保護，但是 用反面磁鐵從記錄的表面一侧消除記錄不充分，所以不 好，另外，作為消除用磁鐵，由於需要使用強磁鐵，所以 在經濟上也是不合算的。The thickness of the adhesive layer, while protecting the microcapsules, is not too thick in terms of eliminating the relationship between the recorded record and goodness. Of course, it should not be too thick under the restrictions of the so-called thin plate. Therefore, the thickness of the bonding layer is preferably 1 0 to 1 8 0 // m. More preferably, it is 3 0 to 1 3 0 // m. This adhesive layer not only joins the film and the solid dispersion layer, but also prevents the microcapsules in the microcapsule coating layer from being damaged by the pressure in the note, so it can display bright text or portraits for a long time, and make the microcapsule magnetic display board It becomes a product with excellent durability. That is, when the thickness of the bonding layer is thinner than 10 m, the protection of the microcapsules is insufficient, and the microcapsules may be damaged due to the pressure in the pen record. In addition, when the thickness exceeds 1 0 0 // m, although sufficient protection can be obtained, it is not good to use a reverse magnet to eliminate recording from the recording surface side, which is not good. In addition, as a magnet for elimination, it is necessary to use a strong Magnets are not economical.
本發明中，更優選使用紫外線硬化性樹脂接合劑作為 保護層。即，在固態分散層用紫外線硬化性樹脂被覆，然 後再在其上接合薄的透明合成樹脂薄膜，用紫外線進行照 射使其硬化，或將固態分散層用紫外線硬化性樹脂被覆的 同時，在其上接合薄的透明合成樹脂薄膜，用紫外線進行 照射使其硬化的方法。接合層中的接合劑，最好使用可與 有細小凹凸固態分散層的表面緊密接合，不會形成空隙的 接合劑或接合方法，因此，從這點上考慮，例如，優選在 微膠囊被覆層上塗布紫外線硬化樹脂形成接合劑層的方 法。由於固態分散層與接合劑層全面貼緊接合（一體In the present invention, it is more preferable to use an ultraviolet curable resin adhesive as the protective layer. That is, the solid dispersion layer is coated with an ultraviolet curable resin, and then a thin transparent synthetic resin film is bonded to the solid dispersion layer and irradiated with ultraviolet rays to harden it, or the solid dispersion layer is coated with an ultraviolet curable resin, and the A method of bonding a thin transparent synthetic resin film to the substrate and curing it by irradiation with ultraviolet rays.

Therefore, in this regard, for example, the microcapsule coating layer is preferably used. A method of applying a UV-curable resin to a bonding agent layer. Because the solid dispersion layer and the adhesive layer are fully and tightly joined (integrated)

Description of the invention (12)), therefore, not only can improve the flexibility (strength against bending) of the microcapsule magnetic display panel, but also fully protect the micro capsule.
另外，前述使用紫外線硬化性樹脂時，具體地說，是 在固態分散層上塗布時，可直接塗布液態的紫外線硬化性 樹脂，用紫外線照射使得液態紫外線硬化性樹脂硬化形成 保護層。或者在固態分散層上使用紫外線硬化性樹脂，在 接合薄膜時，將液態的紫外線硬化性樹脂塗布在固態分散 層上，同時在其上載入合成樹脂薄膜，用紫外線照射使得 液態紫外線硬化性樹脂硬化，固態分散層與紫外線硬化性 樹脂形成一體。因此，合成樹脂薄膜，根據需要可以是可 剝離的。In addition, when the ultraviolet curable resin is used, specifically, when coating on a solid dispersion layer, a liquid ultraviolet curable resin can be directly applied, and the liquid ultraviolet curable resin is cured by irradiation with ultraviolet rays to form a protective layer. Alternatively, a UV-curable resin is used for the solid dispersion layer. When the film is bonded, a liquid UV-curable resin is coated on the solid dispersion layer, and a synthetic resin film is loaded on the solid-dispersion layer, and the liquid UV-curable resin is irradiated with ultraviolet rays. Hardened, solid dispersion layer is integrated with UV-curable resin. Therefore, the synthetic resin film may be peelable if necessary.
本發明中，支援體是可剝離層，該可剝離層的特徵是 剝離後只由固態分散層形成。該可剝離層，由於在固態分 散層形成後剝離，對其厚度沒有特別的限制，可選擇在能 良好地形成固態分散層的範圍内的適宜厚度。作為可剝離 層，通常使用脫膜劑被覆的支援體，特別優選與固態分散 層不接合的支援體。例如，作為固態分散層的枯合劑使用 聚乙烯基醇，作為支援體使用聚對苯二甲酸乙二醇酯薄膜 時，由於兩者之間沒有接合性，可在塗布、乾燥後簡單地 剝離。另外，作為脫膜劑，優選使用石夕氧烧油，F樹脂類 油。 本發明中使用的微膠囊内的分散液中，至少含有一種 磁性粒子，非磁性粒子等，優選磁性粒子與非磁性粒子的 粒徑大小相同。另外，這裏使用分散劑，優選進一步使用 球磨機等機械方法進行分散。這樣可將磁性粒子或非磁性In the present invention, the support is a peelable layer, and the peelable layer is characterized by being formed of only a solid dispersion layer after peeling. Since the peelable layer is peeled after the solid dispersion layer is formed, its thickness is not particularly limited, and an appropriate thickness within a range in which the solid dispersion layer can be formed satisfactorily can be selected. As the peelable layer, a release agent-coated support is usually used, and a support which is not bonded to the solid dispersion layer is particularly preferred. For example, when polyvinyl alcohol is used as a bulking agent for the solid dispersion layer and a polyethylene terephthalate film is used as a support, there is no adhesion between the two, and it can be easily peeled off after coating and drying. In addition, as the release agent, it is preferable to use Shibaishi oil and F resin oil. The dispersion liquid in the microcapsule used in the present invention contains at least one kind of magnetic particles, non-magnetic particles, and the like, and it is preferable that the particle sizes of the magnetic particles and the non-magnetic particles are the same. In addition, a dispersant is used here, and it is preferable to further disperse using a mechanical method such as a ball mill. This allows magnetic or non-magnetic particles

Description of the Invention (13) Dispersions such as particles are dispersed uniformly and for a short time. In addition, it is also preferable to include a fine particle thickener in the dispersion liquid, so that it has the effect of preventing the more uniformly dispersed dispersant from being precipitated and maintaining a stable state for a long time.

When the amount of the dispersant added is less than 0.2% by weight, a satisfactory dispersing effect cannot be obtained, and if it exceeds 10% by weight, the viscosity of the dispersant becomes high and the characteristics of the dispersant are impaired, so it is not preferable.

The amount of the microparticle thickener added to the dispersant may vary depending on the type of the dispersant. The amount of the microparticle thickener relative to the dispersant is 0.2% to 5% by weight, preferably 0.4% to 2% by weight. When the added amount of the microparticle thickening is less than 0.2% by weight, there is no adjustment effect on magnetic particles and non-magnetic particles, and if it exceeds 5% by weight, movement of solid particles such as magnetic particles is prevented from moving, so it is not preferable.

Description of the Invention (14) As the magnetic particles used in the present invention, those that are commonly used in the field may be mentioned, for example, black iron oxide, Porous iron oxide, manganese dioxide-containing iron oxide, chromium dioxide, iron oxide, fine particles of iron or nickel, and magnetic particles such as iron-nickel that have not been subjected to affinity treatment, and magnetic iron oxide is particularly preferred. One kind or a mixture of two or more kinds can be used. Examples of commercially available products include Todaichi KN — 3 2 0 (ferric oxide made by Toda Kogyo Co., Ltd.), Talouskus (Xiguchi 7xa A BL — 5 0 (titanium Synthetic iron oxide manufactured by Industrial Co., Ltd.) and the like. Preferred is magnetic iron oxide represented by F e 3 0 4.

In addition, more preferably 〇1 / 1 / ιι ~ 0.5 / zm, containing 70% or more of 0.2 // m ~ 0. 3 // m Products. If the particle diameter of the magnetic particles in the present invention exceeds 1 0 // m, the sharpness of characters and the like decreases, which is not preferable. In addition, if it is less than 0.1 // m, the speed of writing or erasing is particularly slow. 1 // m ~ 1 // m, particularly preferably 0. 5 // m ~ 1 // m. Magnetic particles subjected to affinity treatment are not preferred because they reduce the ability of the microparticle thickener. Magnetic With respect to the dispersion liquid, 0.3 to 1 0. 0% by weight, preferably 0. 5 to 7. 0% by weight, more preferably 1. 0 to 5. 0% by weight. For the dispersion, the ratio of the magnetic particles is less than 0. At 3% by weight, Vivid characters, portraits, etc. cannot be obtained. In addition, if the ratio of the magnetic particles exceeds 1.0% by weight, not only the mobility of the magnetic particles is deteriorated, but the entire particles become a little black, resulting in unsatisfactory contrast. Examples of the non-magnetic particles used in the present invention include white pigments such as titanium dioxide, barium white, zinc oxide, zinc white, and zinc sulfide.

氧化鈦可使用銳鈦礦型或金紅石型中的任何一種。從遮蓋 力的觀點優選金紅石型氧化鈦。這些都優選比重小的產 品。另外，優選吸油量（吸油是指溶劑被粒子吸收到粒子 内部）較高的產品。該非磁性粒子的粒徑，只要能充分分 散，沒有特別的限制，為〇 · 1 // m〜1 // m，優選0 · 1 // in〜 0. 5 // m。若磁性粒子的粒徑大，氧化鈦的粒徑小，則磁性 粒子移運快，不黑，對比度差。另外，若磁性粒子的粒徑 小，氧化鈦的粒徑大，則出現黑色，雖然對比度變好，但 磁性粒子的移運在邊緣變差，因此也不是優選的。簽於這 樣的事實，可以理解有必要使磁性粒子與非磁性粒子以同 程度的粒徑存在。As the titanium oxide, any of anatase type and rutile type can be used. From the viewpoint of hiding power, rutile titanium oxide is preferred. These are preferably products having a small specific gravity. In addition, a product having a high oil absorption (oil absorption means that the solvent is absorbed into the particles by the particles) is preferable. The particle diameter of the non-magnetic particles is not particularly limited as long as it can be sufficiently dispersed, and is 0 · 1 // m to 1 // m, preferably 0 · 1 // in to 0. 5 // m. If the particle diameter of the magnetic particles is large and the particle diameter of the titanium oxide is small, the magnetic particles will be transported quickly, not black, and poor in contrast. In addition, if the particle diameter of the magnetic particles is small and the particle diameter of the titanium oxide is large, black appears. Although the contrast is improved, the migration of the magnetic particles becomes worse at the edges, which is not preferable. Signed by this fact, it is understood that it is necessary to make magnetic particles and non-magnetic particles exist with the same size.
本發明中使用的非磁性粒子，對於分散液為5. 0〜 50.0重量％，優選10.0〜40.0重量％，更15.0〜35.0重 量％。對於分散液，如果非磁性粒子的比率不足5. 0重 量％，由於薄型，特別是整體有點發黑，不僅對比度不 好，且不能得到鮮明的文字、晝像等。另外，如果非磁性 粒子的比率超過5 0. 0重量％，相反，整體有點白，也不能 獲得滿意的對比度。從這點上考慮，對於磁性粒子，非磁 性離子的比率為4〜3 0倍，優選5〜2 0倍，更優選6〜1 5 倍。這樣即使是薄型，也能得到對比度優良的鮮明畫像。 本發明中使用的微膠囊中的分散液中或該微膠囊的明 膠被膜中，微膠囊被覆層中的透明水性接合劑，透明薄膜 中的至少一種可含有著色劑，進行適當的著色。這樣，可 將磁性顯示板的背面或背景著色成各種顏色。作為這種著 色劑，可使用通常的染料，顏料。作為這種染料或顏料，The non-magnetic particles used in the present invention are 5.0 to 50.0% by weight, preferably 10.0 to 40.0% by weight, and more preferably 15.0 to 35.0% by weight for the dispersion. As for the dispersion liquid, if the ratio of the non-magnetic particles is less than 5.0% by weight, the thinness, especially the blackness of the whole, is not only poor in contrast, but also sharp characters, day images, etc. cannot be obtained. In addition, if the ratio of the non-magnetic particles exceeds 5.0% by weight, on the contrary, the whole is a little white, and satisfactory contrast cannot be obtained. From this point of view, for magnetic particles, the ratio of non-magnetic ions is 4 to 30 times, preferably 5 to 20 times, and more preferably 6 to 15 times. In this way, clear images with excellent contrast can be obtained even with a thin profile.

At this time, it can be used as a board or a seamless product. [Embodiment 2] For the microcapsule magnetic display panel manufactured in Embodiment 1, the type of erasing magnet was changed, and the erasing situation was investigated. When a one-sided multi-pole magnet is used for erasing operation (moving on the surface where the text is recorded), the writing can be erased, but streaks are generated on the surface of the board and cannot be erased in a uniform state. In addition, when the erasing magnet having a surface magnetic flux density of 1100 Gauss was used for erasing, a dark surface was obtained, which cannot be said to be very good. On the other hand, in the present invention, when the erasing magnet with a surface magnetic flux density of 250 Gauss is used for erasing, it is possible to erase the notes cleanly, and to obtain a clean surface with a white surface and no unevenness. In addition, in this example, the magnet is removed by moving the magnet on the surface of the text recording. In the present invention, it goes without saying that the magnet may be removed by moving the inside of the display panel as in a conventional method.

Description of the invention (24) The point solvent is a combination of specific solvents as described above. The ratio is low boiling point relative to 100 parts by weight. The solvent and the high-boiling-point solvent are 20 to 250 parts by weight, so a good microcapsule magnetic recording plate can be obtained. In the present invention, since the colorant can be dispersed or dissolved in at least one of the solid dispersion layer or the dispersion liquid solvent, the surface or the back surface of the recording plate can be colored with a desired color.
本發明的薄型微膠囊磁性泳動記錄板，是可使用在表 面上用磁鐵記錄，且從表面上消除的方法的薄型微膠囊磁 性泳動記錄板。本發明中，磁鐵是具有直徑0. 3〜2 . 0mm， 且表面磁束密度為7 0 0高斯以上的特性值的磁鐵，因此， 可得到對比度更好的微膠囊磁性泳動記錄板。另外本發明 中，由於磁性具有表面磁束密度100〜750高斯的特性值， 因此，可得到對比度更好的微膠囊磁性泳動記錄板。The thin microcapsule magnetic swimming recording board of the present invention is a thin microcapsule magnetic swimming recording board which can be recorded on the surface with a magnet and eliminated from the surface. In the present invention, the magnet is a magnet having a diameter of 0.3 to 2.0 mm and a characteristic value of a surface magnetic flux density of 700 Gauss or more. Therefore, a microcapsule magnetic swimming recording plate with better contrast can be obtained. In addition, in the present invention, since the magnetic has a characteristic value of a surface magnetic flux density of 100 to 750 Gauss, a microcapsule magnetic swimming recording plate with better contrast can be obtained.
