技术领域 FIELD

本发明涉及微胶囊担载片材的制造方法,更详细地讲,以封入功能性材料的微胶囊担载在基材片材上形成的微胶囊担载片材及其制造方法作为对象。 Supporting sheet of the present invention relates to a method of producing microcapsules carrying sheet, and more specifically, to enclose the microcapsules functional material supported on the substrate sheet formed microcapsules and a manufacturing method as a target.

技术背景众所周知把各种的液状功能性材料封入微小胶囊中的微胶囊技术。 BACKGROUND ART The known various functional materials enclosed liquid microencapsulation technology micro capsules. 微胶囊化的功能性材料涂布载负在片材的表面,可对片材赋予各种各样的功能。 Microencapsulated functional material applied on the surface for carrying a sheet, various functions can be imparted to the sheet.

作为这样的微胶囊担载片材的利用领域,已知有封入染料或发色剂的复写片材、封入色素的感光记录片材、封入挥发性溶剂的发泡性片材、封入香料的带香味片材等。 Examples of such art using microcapsules carrying sheet, there is known a dye or color former encapsulated carbon copy sheet, sealed photosensitive dye recording sheet enclosed volatile solvent foamable sheet, enclosed fragrance scented sheet or the like.

有关微胶囊担载片材的制造,已知通过将分散了微胶囊的涂布液涂布在基材片材的表面上,干燥,在基材片材的表面形成微胶囊层的方法。 For producing microcapsules supporting the carrier sheet, it is known by dispersing the microcapsule coating liquid on the substrate surface of the sheet, drying, a method of forming a microcapsule layer on the surface of the substrate sheet. 工业上生产时,连续地将涂布液涂布在连续移动的基材片材表面上,制造连续带状的微胶囊担载片材。 Industrial production, the coating liquid is continuously coated on the surface of the continuously moving substrate sheet, manufacturing a continuous strip of sheet material carrying microcapsules. 制得的微胶囊担载片材多数情况下卷绕成辊状,便于搬运或保管的操作。 The resulting microcapsules wound into a roll carrying the sheet in most cases, to facilitate handling or storage operations.

作为微胶囊担载片材的使用形态,有时在载负微胶囊侧的表面贴合其他材料制的片材或部件使用。 As the microcapsules form supporting sheet is used, sometimes the microcapsules were loaded side of the laminated sheet made of other materials or components. 例如,对封入应答光或温变物质的微胶囊担载片材,有时在载负微胶囊侧的表面贴合玻璃板制造调光玻璃等。 For example, the response of the enclosed light or temperature change substance microcapsules carrying sheet, sometimes the microcapsules were loaded side bonded glass manufacturing dimmer glass.

发明内容 SUMMARY

以往的微胶囊担载片材的制造技术,存在所制得的微胶囊担载片材难使用的问题。 Conventional microcapsules carrying sheet manufacturing techniques, the problems resulting microcapsules carrying sheet unwieldy.

如前所述,只是涂布微胶囊涂布液使其干燥的微胶囊担载片材直接卷绕成辊状层合时,微胶囊层与相邻的微胶囊担载片材的基材片材背面相接触,在微胶囊与基材片材之间容易引起粘连。 As previously described, except that the coating liquid coated microcapsule dried microcapsules carrying sheet is directly wound into a roll lamination, microcapsule layer adjacent microcapsules carrying sheet base sheet contact with the back surface material, between the substrate sheet and the microcapsules liable to cause blocking. 为了使用微胶囊担载片材,从卷绕辊上解开时,与基材片材背面粘合的微胶囊遭到破坏或脱落。 In order to use a sheet carrying the microcapsules, when unwound from the winding roller, and the back surface of the substrate sheet adhered microcapsules destruction or loss.

曾设想把微胶囊担载片材卷绕成辊状时,预先在微胶囊层的表面涂布脱模剂。 When the microcapsules had envisaged carrying sheet is wound into a roll, previously applied to the surface of the release agent in the microcapsule layer. 也考虑过夹入涂有脱模剂的片材、卷绕微胶囊担载片材。 Also considered sandwiched sheet coated with a release agent, microcapsules loaded winding sheet. 认为通过这样,能避免微胶囊与基材片材背面引起粘连。 By that, the microcapsules can be avoided and the back substrate sheet cause blocking. 从卷绕辊上解开微胶囊担载片材时,使微胶囊容易从基材片材背面侧分离,而不破坏微胶囊。 When decoding the microcapsules carried on the winding roller from the sheet, the microcapsules are easily separated from the sheet back surface side of the substrate sheet, without damaging the microcapsules. 然而,如果脱模剂直接粘在微胶囊表面,要想在微胶囊侧的表面贴合其他部件时,由于脱模剂的作用,会发生不能得到足够的密合性或贴合强度的问题。 However, if the releasing agent adhered directly to the surface of the microcapsules, the microcapsules on the surface in order to fit the other side member, since the effect of the release agent will occur no sufficient adhesiveness or bonding strength problems.

本发明的课题是提供将所制造的微胶囊担载片材卷绕成辊状后即使是使用微胶囊也不会产生破坏、在使用微胶囊担载片材时也良好地进行与其他部件的贴合等容易使用的微胶囊担载片材。 Object of the present invention is to provide a microcapsule manufactured supporting sheet wound into a roll shape even after using the microcapsules will not produce damage, also performed well when used with other components microcapsules carrying sheet bonding and other easy to use microcapsules carrying sheet.

本发明微胶囊担载片材是在基材片材上层状地担载微胶囊的微胶囊担载片材,具有前述基材片材、粘合在前述基材片材表面上的前述微胶囊层、以及可剥离地粘贴在前述微胶囊层表面上的再剥离膜。 Microcapsules of the invention is supported on a base sheet is a laminated sheet of the microcapsules loaded microcapsules carrying sheet having the substrate sheet, the adhesive on the surface of the substrate sheet of the micro capsules layer, and then the release film peelably on the surface of the microcapsule layer.

微胶囊的形状没有特殊限定,但优选是球形等的粒子状。 The shape of the microcapsules is not particularly limited, but is preferably a spherical particle or the like shape.

微胶囊的粒径没有特殊限定,但本发明适用性高的是20~200μm。 The particle diameter of the microcapsules is not particularly limited, but the high applicability of the present invention is 20 ~ 200μm. 微胶囊的粒径太小时,要在片材上赋予足够量的功能性物质,必须层积微胶囊,这种场合难均匀担载。 When the particle diameter of the microcapsules is too small, on the sheet to be given a sufficient amount of the functional substance must be laminated microcapsule, this case is difficult to uniformly supported. 粒径太大时,微胶囊的强度不充分,微胶囊往往可能产生龟裂。 When the particle size is too large, insufficient strength of the microcapsules, the microcapsules may often cracked.

制造微胶囊时,可采用通常包含微胶囊化工序的公知制造方法,具体地,可优选使用凝聚法(相分离法)、液中干燥法、熔解分解冷却法、喷雾干燥法、平面涂布法、气中悬浮被覆法与粉床法等所谓的界面沉积法,或界面聚合法、原地聚合法、液中固化被膜(被覆)法(锐孔法)与界面反应法(无机化学反应法)等所谓的界面反应法。 When manufacturing the microcapsules, known methods may be employed generally comprise microencapsulation step for producing, in particular, can be preferably used a coacervation method (phase separation method), a liquid drying method, a melting decomposition cooling method, spray drying method, a coating method plane , gas suspension coating method and so-called powder bed process of interfacial deposition method or an interfacial polymerization, in situ polymerization, a liquid curing coating (covering) method (orifice method) and interfacial reaction method (inorganic chemical reaction method) so-called interfacial reaction method. 其中,更优选凝聚法、原地聚合法、界面聚合法、液中干燥法、熔解分解冷却法。 Wherein, more preferably coacervation method, in situ polymerization, interfacial polymerization, liquid drying method, a melting decomposition cooling method. 而且,这些各种制造方法的微胶囊化工序中,作为胶囊壳体所内包的芯物质要使用前述的液状物质等。 Further, these various microencapsulation step of the manufacturing method, a core material encapsulated by a capsule shell to be used in the liquid material and the like. 如果是这样的方法,由于极容易地制得上述微胶囊而优选。 If such a method, since the above-described very easily obtained microcapsules preferable.

进行微胶囊化工序时,通常必须使液状物质等成为芯物质的状态(例如液滴状的形态),作为这种方法,可以是使用在气相中进行喷雾或滴下等的锐孔等形成液滴状,也可以通过使液状物质在水系介质或非水系介质中分散形成液滴状,没有特殊限定。 When the microencapsulation step, usually the liquid substance must be in a state like core material (e.g. droplets form), as such a method may be used like an orifice for spraying or the like dropped in the gas phase to form droplets shape, may be formed droplets dispersed in an aqueous medium or a non-aqueous medium by which the liquid substance is not particularly limited.

例如,使液状物质分散在水系介质中时,作为水系介质没有特殊限定,但可优选使用水、或水与亲水性溶剂(醇、酮、酯、二醇等)的混合液,使水溶性高分子(PVA(聚乙烯醇)、CMC(羧甲基纤维素)、明胶、阿拉伯树脂等)溶解于水的溶液,在水中添加表面活性剂(阴离子性表面活性剂、阳离子性表面活性剂、非离子性表面活性剂)的溶液,或者将这些水系介质层合的液体等。 For example, so that the liquid substance is dispersed in an aqueous medium, as an aqueous medium is not particularly limited, but preferably water, or water with hydrophilic solvents (alcohols, ketones, esters, glycols, etc.) mixture, the water-soluble polymer (the PVA (polyvinyl alcohol), the CMC (carboxymethylcellulose), gelatin, gum arabic, etc.) was dissolved in water, adding a surfactant (anionic surfactant, a cationic surfactant in water, solution of nonionic surfactant), or a lamination of these liquid aqueous medium and the like. 另外,液状物质分散在水系介质中的量没有特殊限定。 Further, the amount of the liquid substance is dispersed in an aqueous medium is not particularly limited.

微胶囊化工序中微胶囊壳体原料的使用量没有特殊限定。 Microencapsulation step, the amount of microcapsule shell material is not particularly limited.

进行微胶囊化工序时,除了胶囊壳体原料液状物质等,及根据需要使用的水系介质或非水系介质外,也可以适当使用其他的成分。 When the microencapsulation step, in addition to capsule shell material liquid substances and the like, and the external aqueous medium according to need to use non-aqueous medium, can be appropriately used other components.

通常,经微胶囊化工序制得微胶囊后,根据需要采用过滤等分离微胶囊。 Typically, the microencapsulation step to obtain the microcapsules, if necessary, isolated by filtration and the like microcapsules. 例如,使液状物质分散在水系介质等中进行微胶囊化工序时,制备微胶囊后,采用吸滤或自然过滤从水系介质等中分离出微胶囊。 For example, so that the liquid substance is dispersed in an aqueous medium or the like for microencapsulation step, after preparation of the microcapsules, or natural filtration using suction filtration is separated from the aqueous medium, the microcapsules and the like.

分离后,通常采用公知的方法,优选将微胶囊进行分级使之成为所期望的粒径分布。 After separation, usually known method, preferably the microcapsules were graded to become a desired particle size distribution. 另外,为了除去不纯物,提高产品质量,优选对得到的微胶囊进行洗涤操作。 In order to remove impurities, improve product quality, it is preferable to obtain microcapsules washing operation.

[涂布液]为了使微胶囊担载在基材片材上,制备含微胶囊的分散涂布液,把涂布液涂布在基材片材上。 [Coating liquid] In order to make the microcapsules carried on a substrate sheet, a coating solution was prepared containing a dispersion of microcapsules on the substrate sheet in the coating liquid.

涂布液中的微胶囊的含有比例,具体地是20~60重量%,优选是30~50重量%。 Microcapsule coating liquid content ratio, specifically 20 to 60 wt%, preferably 30 to 50 wt%. 微胶囊的含有比例太少时,干燥不充分,涂布膜上形成很多间隙,有可能降低均匀性。 When the content of microcapsules is too small, insufficient drying, the coated film formed a lot of space, it is possible to reduce uniformity. 太多时,涂布液容易凝聚,或由于涂布液的流动性降低,因此有可能难涂布。 When too much, the coating solution easily agglomerate, or to reduce the fluidity of the coating solution, it is possible hard coating.

涂布液中除了微胶囊以外,还可以添加分散剂、粘性调节剂、防腐剂、消泡剂等。 In addition to the coating liquid microcapsules may be added dispersants, viscosity modifiers, preservatives, antifoaming agents and the like.

另外,微胶囊与基材片材的粘合力不足时,可以使用粘合剂。 Further, insufficient adhesion of microcapsules to the substrate sheet, an adhesive may be used.

[基材片材]基材片材起担载微胶囊的作用。 [Substrate sheet] acts as the base sheet carrying the microcapsules.

基材片材的材料可根据微胶囊担载片材的使用目的或用途变更。 Material of the substrate sheet can be changed depending on the intended use of microcapsules or use of carrier-supported sheet. 但必须是可用吻涂方式涂布的强度或柔软性。 However, the intensity must be available, or kiss coating method of coating flexibility.

基材片材可以是只由塑料薄膜构成的片材,也可以是以塑料薄膜为基材,对塑料薄膜实施电晕处理、等离子体处理、UV照射处理的薄膜,或者如蒸镀或层合铝、铜、金、银等金属的层合膜,或者涂布SnO、ZnO、ITO、SiO2等无机氧化物的涂膜等层合其他的基材或物质的薄膜,没有特殊限定。 The base sheet may be a sheet consisting only of plastic film, may be based on a plastic film as the substrate, the plastic film is subjected to corona treatment, plasma treatment, UV irradiation treatment of the film, such as vapor deposition or lamination, or layer of metal such as aluminum, copper, gold, silver or the like laminated film, coating or SnO, ZnO, ITO, SiO2 and other inorganic oxide coating film and the like laminated film or other base material is not particularly limited.

基材片材的厚度根据使用目的或要求性能而不同。 Thickness of the substrate sheet according to the intended use or performance requirements differ.

[易粘着性片材]作为基材片材,可以使用在担载微胶囊侧的表面有易粘着性的易粘着性片。 [Adhesiveness sheet] As the base sheet, may be used in carrying microcapsules side surface adhesiveness of the adhesive sheet easily.

易粘着性片构成的基材片材可有效地使微胶囊担载在基材片材上。 The substrate sheet formed of sheet adhesiveness microcapsules can be effectively supported on the base sheet. 担载在基材片材上的微胶囊难脱落。 Supported on the substrate sheet off microcapsule difficult. 易稠密地担载单层的微胶囊。 Easy single densely loaded microcapsules.

作为易粘着性片的材料也根据微胶囊的材料而不同,可以使用聚酯系、丙烯酸系、环氧系、氨基甲酸酯系、噁唑啉系、PVP系、聚氧链烷烯系、纤维素不等的水溶性或水分散性、乳液系树脂。 As the material sheet has adhesiveness depending on the material and the microcapsules differ, a polyester, acrylic, epoxy, urethane-based, oxazoline-based, PVP-based, polyoxyalkylene alkyl chain olefinic, cellulose ranging from water-soluble or water-dispersible, resin-based emulsion. 可在通常的基材片材表面涂布易粘着材料的层。 Layer may be generally applied to the surface of the substrate sheet material adhesiveness. 对基材片材上易粘着层的制作可采用通常的涂布技术。 Conventional coating techniques on a substrate sheet made of easy-adhesive layer may be employed.

[涂布装置]作为涂布装置,可以使用通常微胶囊涂布技术中利用的涂布装置。 [Coating Apparatus] As the coating apparatus, the coating apparatus may be used generally in the microcapsule coating technique utilized. 优选基本涂布方式采用吻涂方式的涂布装置。 Preferably substantially coating method using the coating apparatus of the kiss coating method.

吻涂方式,是使附着涂布液的涂布辊相对于连续移动的基材片材边旋转边接触,使涂布液从涂布辊上移到基材片材上,从而将涂布液涂布在基材片材上。 Kiss coating method, the coating liquid is adhered to the application roller relative to the substrate sheet is continuously moving while rotating in contact, the coating solution on the application roller is moved from the substrate sheet so that the coating liquid coated on the substrate sheet. 此时,在基材片材与涂布辊进行接触的位置,基材片材的内涂布辊的接触面与相反侧的面呈开放状。 At this position, the contact of the base sheet and the coating roll, leaving it open contact surfaces with the application roller in the opposite side of the sheet substrate. 不存在通常的辊涂布机或照相凹版涂布机等中的加压辊或支撑辊。 A pressure roller or the support rollers usual roll coater or a gravure coater does not exist.

基材可在轻轻放到涂布辊上程度的压力下进行接触。 The substrate may be contacted at gently placed on the degree of pressure application roller. 具体地,预先在基材片材与涂布辊的接触位置的上游侧与下游侧配置导向辊。 In particular, the guide rollers arranged in advance on the upstream side and the downstream side of the contact position of the base sheet and the coating roll. 沿导向辊之间切线方向直线地移动的基材片材用涂布辊略微弯曲地变形。 Between the tangential direction along the guide rollers linearly moving the substrate sheet is slightly deformed by the bending roll coating. 基材片材弯曲变形产生的压力作用于基材片材与涂布辊之间。 Substrate sheet bending deformation pressure is applied between the base sheet and the coating roll.

吻涂方式的涂布装置,可以将基材片材的移动方向与涂布辊的旋转方向设定成相同方向,也可以设定成相反方向。 Coating apparatus kiss coating method, the rotational direction of the moving direction of the substrate sheet with a coating roll may be set to the same direction, it may be set to the opposite direction. 相同方向时可预先设定速度差。 When a speed difference may be set in advance in the same direction.

把涂布辊的旋转方向相对于基材片材移动方向设定成反方向的涂布技术称作逆涂布方式。 The rotational direction of the application roller with respect to the moving direction of the substrate sheet is set to the opposite direction is referred to as coating techniques reverse coating method. 采用逆涂布方式时,附着在涂布辊上的涂布液在与基材片材的接点转印到基材片材上。 When using reverse coating method, roll coating adheres to the transfer coating solution with the contact substrate sheet to the substrate sheet. 由于在接点基材片材与涂布液只是轻轻地接触,故对微胶囊不施加过大的压力。 Since only lightly in contact with the coating liquid contacts the substrate sheet, so the microcapsules are not apply excessive pressure. 另外,在接点处涂布液从基材片材与涂布辊两方拉伸后由于施加适度的负荷(剪切力),故涂布液均匀地转印在基材片材上。 Further, after the coating solution contacts the substrate sheet from the stretched and both the application roller due to the application of a moderate load (shearing force), so that the coating was uniformly transferred onto the base sheet.

涂布辊的旋转方向与基材片材的移动方向相同的场合,虽然不是逆向涂布方式,但只要是吻涂方式,则在前述的涂布辊与基材片材的接点处,由于基材片材与涂布辊只是轻轻地接触,故对微胶囊不施加过大的压力。 Same case moving direction of rotation of the application roller and the substrate sheet, although not reverse coating method, kiss coating method as long as, at the junction of the application roller and the substrate sheet, since the base the sheet material only lightly in contact with the coating roll, so the microcapsules are not apply excessive pressure.

如果对涂布辊的圆周速度与基材片材的移动速度设定适宜的差别,则利用其速度差,涂布液在基材片材上被拉伸后易薄薄地形成均匀的涂布层。 If the difference is set to a suitable peripheral speed of the application roller movement speed of the substrate sheet, using the speed difference, easy to form a uniform thin coating layer after the coating liquid is stretched on the base sheet .

基材片材的移动速度也根据涂布后的干燥条件而不同,通常可设定在0.1~10m/分的范围。 The moving speed of the substrate sheet is also in accordance with the drying conditions after coating, and is generally be set in the range of 0.1 ~ 10m / min. 太慢时生产效率差,太快时干燥不好,容易粘连。 Slow production efficiency is poor, poor drying too fast, easy adhesion.

涂布液在基材片材上的涂布厚度也根据涂布液中所含的微胶囊而不同,通常在湿状态下设定成1~300μm,干燥后的厚度可设定成1~100μm的范围。 The coating thickness of the coating solution on a substrate sheet A microcapsule coating solution also contained, and is generally set to 1 ~ 300μm in a wet state, the thickness after drying may be set to 1 ~ 100μm It ranges. 最有效地发挥本发明的效果是干燥后的厚度在10~100μm的范围。 Most effectively exhibit the effect of the present invention, the thickness after dried is in a range of 10 ~ 100μm. 优选设定涂布液的厚度是微胶囊外径的1.0~3.0倍。 The thickness of the coating solution is preferably set to 1.0 to 3.0 times the outer diameter of the microcapsules.

吻涂方式的涂布装置,配置涂布辊要使之在涂布作业中可以对基材片材时而靠近时而离开地移动。 Kiss coating method of the coating apparatus, the coating roll disposed to make the coating operation for the substrate sheet can sometimes be moved close to and sometimes away. 这样如果调节涂布辊与基材片材的间隔,则可以正确地调节涂布厚度。 Such adjustment interval if the application roller and the substrate sheet, the coating thickness can be adjusted properly. 如果涂布辊完全成离开基材片材的状态时,可断续地沿基材片材的长度方向涂布涂布液。 If the application roller is completely separated state into the substrate sheet, the coating solution may be applied intermittently along the longitudinal direction of the substrate sheet. 可以制造断续地配置微胶囊担载领域的微胶囊担载片材。 It can be produced intermittently arranged art microcapsules carrying microcapsules carrying sheet.

[微型照相凹版涂布机]众知微型照相凹版涂布机是吻涂方式且为逆向涂布方式的涂布装置。 [Micro gravure coater] well known micro gravure coater, kiss coating method and reverse coating means a coating method. 具体地,以特公平5-53553号公报公开的涂布技术为基础。 Specifically, the coating technique disclosed in KOKOKU Publication No. 5-53553 is based.

涂布辊外周面有照相凹版图案。 Coating roll has an outer peripheral surface of the gravure pattern. 照相凹版图案是微细凹凸形成的图案状的花纹,附着在照相凹版图案上的涂布液呈可靠地被照相凹版图案的凹凸支撑的状态输送、涂布在基材上。 A gravure pattern is a fine concavo-convex pattern-formed pattern, the pattern deposited on the gravure coating liquid was conveyed reliably support the uneven pattern of gravure state, coated on the substrate. 涂布液中的微胶囊利用照相凹版图案的凹凸易于带起或输送。 Microcapsule coating solution using a gravure pattern of irregularities easily brought up or delivery. 可以防止只是涂布液的液体成分附着在涂布辊的表面上。 Can be prevented but the liquid content of the coating liquid adheres to the surface of the coating roll.

照相凹版图案的大小或形状,可以从通常涂布涂料或油墨所使用的微细照相凹版涂布机采用的条件中,选用适合于微胶囊担载的条件,可对照分散在涂布液中的微胶囊的粒径设定照相凹版图案的深度或沟间距。 Gravure pattern size or shape, from the micropores conditions may be employed a gravure coater coating or ink coating is generally used, the selection of conditions suitable for carrying the microcapsules, the control can be finely dispersed in the coating liquid the particle size of the capsule or to set the depth of groove pitch gravure pattern. 作为图案形状,可以将相对于涂布辊轴向倾斜的倾斜线在涂布辊的周面上呈螺旋状地并列配置。 As the pattern shape may be applied with respect to the axial direction of the roll inclined wire spirally in the circumferential surface of the coating roller arranged in parallel. 也可以利用相互交叉的倾斜线形成格子状的照相凹版图案。 It may be a lattice-like pattern by using a gravure oblique lines crossing each other. 除此之外,还可以采用通常微型照相凹版辊采用的照相凹版图案。 In addition, a gravure pattern may also be employed a micro gravure roll is usually employed. 要涂布含外径较大微胶囊的分散涂布液,预先设定深而大的照相凹版图案的沟效果好。 To the coating liquid containing the coating dispersion microcapsules larger outer diameter, a predetermined groove depth and a good effect of large gravure pattern.

照相凹版图形的槽容积可设定成50~200ml/m2。 Tank volume gravure pattern may be set to 50 ~ 200ml / m2. 槽容积太小时,难担载粒径大的微胶囊。 When the tank volume is too small, a large diameter hard carrying microcapsules. 槽容积太大时,照相凹版图案的凹凸转印在涂布膜上,难均匀地配置微胶囊。 When the tank volume is too large, the uneven pattern is transferred gravure coating film is difficult to uniformly arranged microcapsules.

比一般照相凹版涂布机中的涂布辊外径相当小地设定涂布辊的外径。 Setting the outer diameter of the coating roll is considerably smaller than the outer diameter of the coating roll is generally gravure coater. 具体地,根据涂布液的材料或涂布条件而不同,通常直径设定在20~60mm的范围。 Specifically, depending on the material or coating conditions of the coating liquid varies, typically have a diameter set in a range of 20 ~ 60mm.

涂布辊的旋转是与基材片材的移动方向相反的方向。 Spin coating roller is the direction opposite to the moving direction of the substrate sheet. 涂布辊的旋转根据基材片材的移动速度等的条件而不同。 Rotating the application roller moving speed according to the conditions of the substrate sheet and the like differ. 通过适当地设定涂布辊相对于基材片材移动速度的旋转数,即周速,可以使微胶囊均匀地涂布在基材片材上。 By appropriately setting the number of rotations of the application roller with respect to the moving speed of the substrate sheet, i.e. the peripheral speed, the microcapsules may be uniformly coated on the substrate sheet. 可以设定涂布辊相对于基材片材移动速度的圆周速度的倍率,即速度比为2~20倍。 It may be set with respect to the application roller the peripheral speed of the moving speed of the substrate sheet of the magnification, i.e., the speed ratio is 2 to 20 times. 速度比太小时,涂布液的涂布量不够,担载在基材片材上的微胶囊的均质性降低。 Speed ​​ratio is too small, the coating amount of the coating solution is insufficient homogeneity supported on the base sheet microcapsules decreases. 速度比太大时,涂布辊的旋转速度太快,涂布液从涂布辊向基材片材上的转印效率降低,涂布量不够,或者引起从涂布液的储存器中溢出。 Speed, the rotational speed of the application roller is too fast, much lower than that when the coating liquid from the coating roll to the transfer efficiency on the substrate sheet, the coating amount is not enough, or results in an overflow from the reservoir of the coating liquid .

微型照相凹版涂布机,可在涂布辊与基材片材接触的前面设刮板装置。 Front micro gravure coater, the coating roller contactable with the sheet substrate provided squeegee assembly. 刮板装置调节附着在涂布辊上的涂布液的量,有利于向基材片材供给适量的涂布液。 The amount of the coating liquid adhered to the blade means for adjusting the coating roll, an appropriate amount of beneficial coating liquid supplied to the substrate sheet.

[干燥固化]通过使涂布在基材片材上的涂布液干燥固化,可以使微胶囊担载在基材片材上。 [Dryness] By coating liquid on a substrate sheet is dried and solidified, the microcapsules may be supported on the base sheet.

在涂布液中配合粘合剂的场合,粘合剂起将微胶囊粘在基材片材上的作用。 The case with the binder in the coating liquid, the adhesive from the microcapsules adhered to the substrate sheet action.

干燥作业采用自然干燥与强制干燥。 Natural drying and drying operations using the forced drying. 作为强制干燥可采用热风干燥或远红外线干燥等公知的干燥方法。 As can be forced hot air drying or far infrared ray drying a known drying method of drying.

涂布液的固化,可根据涂布液中所含粘合剂的成分采用不同的固化方法。 Curing the coating liquid, curing method may be employed according to different components contained in the coating liquid binder. 可列举利用溶剂的蒸发固化、加热固化、紫外线等的放射线照射固化等。 By evaporation of the solvent include curing, heat curing, radiation irradiation such as ultraviolet curing.

[再剥离薄膜的层合]微胶囊担载在基材片材上的微胶囊担载片材,通过在微胶囊侧的表面粘贴再剥离薄膜,可以形成基材片材、微胶囊层与再剥离薄膜层合的微胶囊担载片材。 [Peelable laminated film] microcapsules carried on a substrate sheet supporting microcapsule sheet, pasted the release film can be formed by the surface of the substrate sheet side of the microcapsule, the microcapsule layer and then the release film is laminated to a sheet carrying the microcapsules.

再剥离薄膜是层合在微胶囊担载片材的表面上时,呈现较弱的附着性形成一体化,则若施加力则可以比较容易地剥离的材料。 Then when the release film is laminated on the microcapsule sheet supporting surface, exhibits a weak adhesion formed integration, if the force is applied may be relatively easily peeled off the material.

通过再剥离薄膜的层合,在层合微胶囊担载片材时,可以防止所载负的微胶囊粘附在重叠相邻的微胶囊担载片材的背面引起粘连。 By peelable laminated film, the laminated microcapsule sheet when supported, can prevent the negative contained in microcapsules adhered on the back surface cause blocking overlapping adjacent microcapsules carrying sheet. 也有被覆微胶囊的表面保护微胶囊的作用。 There is also the surface protective coating microcapsules microcapsules effect. 把微胶囊担载片材卷绕后以卷绕辊的状态搬运或使用均容易。 After the sheet carrying the microcapsules in a state wound winding roller or handling are easy to use.

作为再剥离薄膜,适合使用剥离性良好的聚烯烃系薄膜。 As a further release film, good releasability suitable for polyolefin film. 例如,可列举微粘着聚乙烯系薄膜、双向拉伸聚丙烯、未拉伸聚丙烯等的聚丙烯薄膜。 For example, a polyethylene-based adhesive include a micro film, biaxially stretched polypropylene, unstretched polypropylene film. 作为微粘着聚乙烯系薄膜,可以使用混入粘着性物质的单层结构的薄膜,或涂布微粘着性物质的多层结构的薄膜。 As a sparingly adhesive polyethylene film, the film may be used mixed with an adhesive material of a single layer structure or a multilayer structure of the film coating of the micro-adhesive material.

再剥离薄膜的厚度适合40~120μm,更优选50~100μm。 Suitable peelable film thickness of 40 ~ 120μm, and more preferably 50 ~ 100μm. 厚度太薄时容易折皱,难使用。 Wrinkles easily when the thickness is too thin, difficult to use. 厚度太厚时,将微胶囊担载片材卷成辊时加重,使用的操作性差,使用后废弃物量增加。 When the thickness is too thick, the microcapsules carrying sheet when the sheet wound into a roll increased, operability using a difference, increasing the amount of waste after use.

将再剥离薄膜层合在微胶囊担载片材上,通过将微胶囊担载片材与再剥离薄膜简单地重合卷绕,可以彼此层合。 Jiangzai release film laminated on the sheet carrying the microcapsules, the microcapsules by carrying sheet and then winding the release film superposed simply be laminated to one another. 在卷绕之前,通过加压或加热,也可以提高微胶囊担载片材与再剥离薄膜的一体性。 Before winding, by pressure or heat, can be improved microcapsules carrying sheet and the re-release of one film.

在微胶囊担载片材的微胶囊层上粘贴再剥离薄膜时,施加9.8~196N/cm2(1~20kgf/cm2)的压力效果好。 When the re-peeling adhesive film on the microcapsule layer microcapsules supporting sheet, applying good 9.8 ~ 196N / cm2 (1 ~ 20kgf / cm2) pressure effect. 压力越高越可以牢固地粘着,但压力太大时,使微胶囊变形或破坏,在剥离再剥离薄膜时难剥离。 The higher the pressure can be firmly adhered, but too much pressure, deformation or destruction of the microcapsules, difficult to re-peeling when peeling the release film.

[卷绕辊]层合有再剥离膜的微胶囊担载片材卷绕成辊状,可以以卷绕辊的形态进行搬运、保管等的操作。 [Winding roller] then laminated with a release film carrying a microcapsule sheet is wound into a roll, it can be operated handling, storage, etc. in the form of a winding roller.

卷绕作业可以采用与常用片材卷绕作业同样的装置和作业条件。 The winding job can use the same apparatus and operating conditions with the conventional sheet member wound job. 卷绕状态可以成为对微胶囊担载片材与再剥离薄膜之间施加某程度卷压的状态。 Wound state may be applied to a certain extent the state of the rolled sheet carrying the microcapsules and removability between films. 该卷压可以设定成与前述的粘贴时所施加的压力同程度的压力。 The crimping may be set to the same level of pressure when the pressure exerted by the paste. 在施加卷压的状态下保持的卷绕辊,有微胶囊层的表面平滑化的作用。 Winding roller held in the rolled state is applied, the surface layer of microcapsules smoothing effect. 使用微胶囊担载片材时,具有微胶囊层与其他的部件贴合时增大接触面积的优点。 When using microcapsules carrying sheet, an advantage microcapsule layer of bonding with other members of the contact area.

[微胶囊担载片材]微胶囊担载片材系在基材片材的表面粘合微胶囊。 [Microcapsule sheet supporting] microcapsules carrying pressure-sensitive adhesive sheet microcapsule surface of the substrate sheet. 再在微胶囊层的表面粘贴再剥离薄膜。 Then pasted on the surface of the microcapsule layer peelable film.

根据用途或目的,通过涂布辊与涂布条件的设定组合,可容易地实现稀松地担载微胶囊或稠密地担载微胶囊或多层担载微胶囊。 The use or purpose, by setting a combination of the application roller and the coating conditions, the scrim can be easily realized loaded microcapsules or densely loaded microcapsules or microcapsules loaded multilayer.

微胶囊担载层的厚度根据用途而不同。 Microcapsules carrying layer thickness varies depending on the use. 需要稠密地担载微胶囊的用途中,优选将微胶囊层的厚度设定成10~100μm。 Requires the use of densely loaded microcapsules, microcapsule layer thickness is preferably set to 10 ~ 100μm. 厚度太小时,在面方向微胶囊彼此之间容易形成间隙。 When the thickness is too small, the microcapsules in the surface direction gap is easily formed therebetween. 厚度太大时,形成微胶囊层用的涂布液难均匀涂布。 When the thickness is too large, the coating liquid is difficult to form a uniform coating layer of the microcapsule.

微胶囊层中也有时微胶囊形成与涂布液中的微胶囊形状一样的形态,也有时涂布后干燥产生变形。 A microcapsule layer of microcapsules may also be formed with the shape of a microcapsule coating solution of the same form, sometimes deformed after the application and dried. 例如,有时成球状、有时成球略微变形的形状。 For example, sometimes a spherical shape, sometimes slightly deformed into the shape of a ball. 邻接的微胶囊彼此的接触部分或微胶囊与基材片材的接触部分等,也可以类似于彼此挤碎一样地变形以面状接触。 Microcapsules adjacent to each other or the contact portion like the contact portion microcapsules substrate sheet, may also be similar to each other crushing deformation in the same manner as a planar contacting. 微胶囊除了完全均匀地配置一层以外,在不破坏所期望功能的范围内,一部分位置的微胶囊也可以部分地或多层地层合。 In addition to a completely uniform microcapsule layer arranged in a desired function without damage range, part of the location of the microcapsules may be partially or laminating the multilayer.

显示媒体用途时,最好稠密地担载微胶囊。 Use the display medium, preferably densely loaded microcapsules.

本发明的微胶囊担载片材,由于是微胶囊担载在基材上的状态下,用再剥离薄膜覆盖微胶囊层的表面,因此将微胶囊担载片材移送到下面的处理工序,或暂时保管或输送时,可有效防止强度较差的微胶囊损伤、或防止封入被泄漏。 Microcapsules of the invention the supporting sheet, as is supported on a substrate microcapsules state, then with the release film covering a surface layer of microcapsules, microcapsules thus supporting the sheet is transferred to the next treatment step, when storing or transporting or temporarily, can effectively prevent damage to poor strength of the microcapsules, or being enclosed to prevent leakage. 可以利用再剥离薄膜阻止粘合在基材上的部分微胶囊从基材片材上脱落。 It may be utilized to prevent further release film on a substrate portion adhered microcapsule sheet detached from the substrate.

另外微胶囊涂布液涂布在基材片材上后,即使是微胶囊还没有完全粘合、或粘合剂没有充分干燥固化的状态,只要是用再剥离薄膜覆盖的状态,则可以保管等的操作。 Further microcapsule coating solution is coated on the substrate sheet, the microcapsules are not even fully bonded, the adhesive is not sufficiently dried or cured state, as long as the state of the film with a removable cover, can keep and other operations. 可以将微胶囊担载片材卷绕成卷绕辊供于保管或搬运。 Microcapsules may be loaded into a sheet wound on the winding roller for storage or transport. 结果,不需要长时间地涂布后的养生或占很大的空间,可以立即进行下一步的处理工序或运输等的操作。 As a result, the coating does not require a long time regimen or accounts for a large space, the next operation may be a process step or transported immediately.

此外,通过在微胶囊担载片材的微胶囊侧的表面粘贴平滑的再剥离薄膜,微胶囊层的表面产生平滑化的作用。 Further, the surface of the microcapsules in the microcapsule side of the sheet supporting smooth paste peelable film, the surface layer of microcapsules produced smoothing effect. 尤其是通过粘贴再剥离薄膜时施加某程度的压力、或通过成为对卷绕辊施加卷压的状态,促进微胶囊层的平滑化。 Particularly a certain degree of pressure applied during re-attached by a release film, or by applying a state rolled on winding roller, promote a smooth layer of the microcapsule. 结果,消除涂布时产生的微胶囊的浮起或表面的微小凹凸、弯曲变形等,在剥离再剥离薄膜后,可得到表面平滑性非常好的微胶囊担载片材。 As a result, fine irregularities or surface floating microcapsules generated during coating to eliminate bending deformation, and then after peeling the release film to obtain a very good surface smoothness of the sheet carrying the microcapsules. 在微胶囊层的表面贴合其他的部件使用时,可以良好地进行贴合。 When the surface of the microcapsule layer is bonded to another member used, it can be satisfactorily bonded.

[微胶囊担载片材的结构]在PET等合成树脂材料制的基材片材10的表面,无间隙地均匀配置呈略球状的微胶囊20。 [Microcapsule sheet supporting structure] in the surface of the substrate sheet made of a synthetic resin material of PET or the like 10, disposed without a gap has an approximately uniform spherical microcapsules 20. 微胶囊20是在透明树脂等构成的略球状外壳22的内部,封入作为芯物质的封入液24。 Inside the microcapsules 20 are slightly spherical shell made of transparent resin or the like 22, as a core substance encapsulated enclosed liquid 24.

图1中,微胶囊20是埋入透明粘合剂层32中的状态,粘合剂层32与基材片材10层合一体化,但也可以没有明显的粘合剂层32,只是微胶囊20与基材10的接触部位或微胶囊20彼此的接触部位用少量的粘合剂粘合。 In FIG 1, the microcapsules 20 are embedded in the transparent adhesive layer 32 in a state, the adhesive layer 32 and the substrate sheet 10 laminated integrated, but may be no obvious adhesive layer 32, only slightly contact portion 20 of the capsule 10 with the substrate contact portion 20 or microcapsules with each other with a small amount of adhesive. 另外,如果使被覆微胶囊20的粘合剂层32比微胶囊20的外径足够地厚,则也可以起保护微胶囊20的作用。 Further, when the adhesive layer 20 covering the microcapsule 32 is thick enough than the outer diameter of the microcapsules 20, it is also possible protective effect of the microcapsules 20.

此外,实际制造使用的微胶囊担载片材,微胶囊20有时彼此压碎地变形呈非球状、或者微胶囊20的一部分相对于基材片材10的表面略微浮起、或者微胶囊20彼此一部分重合。 In addition, the use of actual manufacturing microcapsules carrying sheet, the microcapsules 20 may be crushed in a non-deformed spherical shape to each other, or a portion of the microcapsules 20 is slightly floated to the surface of the base sheet 10, the microcapsules 20 to one another or partially overlapped. 有时微胶囊20中也根据用途而以多层存在。 Microcapsules 20 may also be present in multiple layers depending on the use.

[再剥离薄膜]在微胶囊20与粘合剂层32的表面上粘贴再剥离薄膜12。 [Peelable film] and then the release film 12 is attached on the surface of the microcapsules 20 and the adhesive layer 32.

再剥离薄膜12由微粘着聚乙烯系薄膜等构成,采用较弱的粘合力粘贴在微胶囊20的表面上。 And then the release film 12 composed of a micro adhesive polyethylene film or the like, using a weaker adhesive force on the surface of the microcapsules affixed to 20.

由于存在再剥离薄膜12,故微胶囊20与粘合剂层32不露到外部。 Due to the presence of another release film 12, so that the microcapsules 20 and the adhesive layer 32 is not exposed to the outside. 可确保防止尘埃或异物附着在表面上。 Ensure the prevention of dust or foreign matter can adhere to the surface. 将微胶囊担载片材S移送到下面的处理工序,或在暂时保管期间,即使器物与微胶囊担载片材S的表面接触,再剥离薄膜12可以良好地防止微胶囊20损伤。 Microcapsules carrying the sheet S is transferred to the next treatment step, or during temporary storage, even if the objects supported in surface contact with the microcapsules contained in the sheet S, and then the release film 12 can be favorably prevented damage the microcapsules 20.

[再剥离薄膜的层合]图2模式性地表示再剥离薄膜的层合作业。 [Peelable laminated film] FIG. 2 schematically represents a further layer of release film industry cooperation.

边连续地使基材片材10担载微胶囊20状态的微胶囊担载片材S移动,边向移动方向供给再剥离薄膜12,利用夹紧辊64、64,将微胶囊担载片材S与再剥离薄膜12夹拢,微胶囊担载片材S与再剥离薄膜12一体地层合。 Side of the substrate sheet is continuously loaded microcapsules 10 20 microcapsules loaded state the sheet S is moved while moving direction re-supplied to the release film 12 by pinch rollers 64, 64, the sheet carrying the microcapsules S and then the release film 12 is sandwiched rope, microcapsules loaded with another sheet S is integrally laminated with the release film 12. 此时施加的压力可以是再剥离薄膜12轻轻地附着在微胶囊担载片材S上的程度,不施加使微胶囊20破坏或过度变形的太大的压力。 Pressure applied at this time, then the release film 12 can be lightly adhered extent carrier sheet S supported microcapsules, the microcapsules is not applied pressure of 20 too much damage or excessive deformation.

通过使微胶囊担载片材S与再剥离薄膜12夹拢压接,可以用足够的力粘贴再剥离薄膜12,同时也提高使微胶囊担载片材S的表面平滑化的作用,再剥离薄膜12的平滑表面与微胶囊担载片材相接施加压力时,例如,即使微胶囊微微从基材片材10浮起,也可以用再剥离薄膜12抑制消除浮起。 By the microcapsules carrying the sheet S and then the release film 12 is sandwiched rope crimp can with sufficient force paste and then the release film 12, but also improve the microcapsules supporting surface of the sheet S smoothing effect, re-peeling smoothing the surface of the film 12 and the sheet carrying the microcapsules contact pressure is applied, for example, even if the microcapsules 10 slightly lifted from the base material sheet may be re-used to eliminate the release film 12 to suppress floating. 即使在微胶囊20或粘合剂层32的表面产生微细的凹凸或起伏,也通过相接平滑的再剥离薄膜12实现均匀化。 Even if the surface of the microcapsules 20 or the adhesive layer 32 of the fine unevenness or undulation generated, and then the release film 12 is achieved by contact with a smooth uniform.

如果微胶囊担载片材S的表面在还有粘附性或柔软性的阶段层合再剥离薄膜12,则确保再剥离薄膜12层合一体化。 If the supporting surface of the microcapsules contained in the sheet S as well as the flexibility of the adhesive or lamination stages and then the release film 12, and then to ensure that the release film 12 laminated integrated. 也良好地发挥前述的平滑化的作用。 Also exhibit excellent effect of smoothing the foregoing.

层合有再剥离薄膜12的微胶囊担载片材S,可以卷绕成辊状回收。 Laminated with a peelable film 12 of microcapsules loaded sheet S, the recovery may be wound in a roll. 如果以卷绕辊的状态进行输送或保管等操作,则容易进行操作,在这种卷绕处理时,通过在卷绕辊R的状态下产生卷压的这种条件下卷绕,促进使用再剥离薄膜12的微胶囊20层的平滑化。 If other transportation or storage of the operating winding roller in a state, it is easy to operate, during this winding process, by which the rolled condition occurs in a state wound around the winding roll R, and then promote the use of the release film 12 of microcapsules 20 smoothing layer.

使用微胶囊担载片材S时,从卷绕辊R的一端解开拉出,可以剥离表面的再剥离薄膜12。 Using microcapsules, when loading sheet S, pulled out from one end to unlock the winding roller R, the surface can be peeled off the release film 12 again. 如图1所示,可以容易地从微胶囊担载片材S的表面上剥下再剥离薄膜12。 As shown in FIG. 1, and then can be easily peeled from the release film 12 on the surface of the carrier supporting the microcapsule sheet S. 除去再剥离薄膜12的微胶囊担载片材12,直接与其他的薄膜或玻璃板等层合用于制造各种制品。 Then removing the release film 12 of microcapsules carrying sheet 12, directly with other films or laminated glass for the manufacture of various articles.

卷绕辊R由于在重合的微胶囊担载片材之间存在再剥离薄膜12,故微胶囊担载片材S彼此不粘合,或者微胶囊20与邻接的基材片材10不粘连。 Because of the winding roll R between the overlapping sheet carrying the microcapsules and then the release film 12, so that the microcapsules are not supporting the sheet S bonded to each other, or adjacent to the microcapsules 20 and the substrate sheet 10 is not blocking.

尤其是,在将微胶囊担载片材S与其他的薄膜或部件层合或接合的中间工序中,在保管或使用微胶囊担载片材S时,有时微胶囊担载片材S的微胶囊侧的表面有强的粘附性。 In particular, the microcapsules carrying the sheet S and the other film or laminating member or engage an intermediate step, during storage or microcapsules carrying the sheet S, and sometimes the microcapsules supporting microcarrier sheet S side surface of the capsule has a strong adhesion. 这样的场合,再剥离薄膜12的存在则有效。 Such a case, then the presence of the release film 12 is effective. 例如,在基材片材10上涂布含微胶囊的涂布液,干燥后,到含于涂布液中的粘合剂充分固化之间,微胶囊20容易从基材片材10上脱落或移动或损伤表面。 For example, the sheet 10 is coated on a substrate a coating liquid containing microcapsules, after drying, the coating liquid contained in the adhesive between the sufficiently cured, the microcapsules 20 easily peeled from the base sheet 10 or move or damage the surface. 这时利用再剥离薄膜12有效地保护。 In this case the use of the release film 12 and then effectively protected.

[微胶囊担载工序]图3~5表示有关层合再剥离薄膜12前的微胶囊担载片材的制造方法,该实施方案中,使用微型照相凹版涂布机,使微胶囊20担载在基材片材10上。 [Step microcapsules carrying] Figures 3-5 represent the relevant method of manufacturing a peelable laminated film before the microcapsules carrying sheet 12, in this embodiment, using a micro gravure coater, the microcapsules carrying 20 10 on the substrate sheet.

[微型照相凹版涂布机]微型照相凹版涂布机,具有使用图3、4所示微型照相凹版辊40的特点。 [Micro gravure coater] a micro gravure coater having a gravure in micro FIG roller 40 shown in FIG. 3 and 4.

[微型照相凹版辊]如图4所示,辊外周面有照相凹版图案部42。 [Micro gravure roller] As shown, the roller outer peripheral surface portion 424 a gravure pattern. 照相凹版图案部42是采用机械雕刻微细的凹凸或采用蚀刻处理形成的凹凸。 A gravure pattern portion 42 is the use of mechanical engraving fine irregularities or irregularities using an etching process is formed. 图4的场合,在圆筒状的外周面有倾斜直线状的凹沟呈螺旋状卷绕的状态紧贴配置的照相凹版图案部42。 The case of Figure 4, the cylindrical outer peripheral surface inclined linear grooves form a gravure pattern portion in close contact with the spirally wound configuration 42. 照相凹版图案部42的全幅W与基材片材10的宽度一致地设定。 Full-width web W and the substrate sheet 42 of a gravure pattern portion 10 is set in unison. 也可以与基材片材10的宽度完全不一致。 It may be completely inconsistent with the width of the substrate sheet 10.

如图3所示,微型照相凹版辊40呈水平状态旋转自如地被支撑态,利用发动机(省略图示)等驱动旋转。 3, the micro gravure roll 40 in a horizontal state is rotatably supported state, by the engine (not shown) is driven to rotate.

微型照相凹版辊40的下方备有涂布液30的贮存器38。 Below the micro gravure roller 40 with the reservoir 30 of the coating liquid 38. 涂布液30是使微胶囊20与粘合剂层32的材料等在溶剂中分散或溶解后,容易涂布的微胶囊分散液。 30 is a coating liquid of the material and the adhesive layer 20 of microcapsules 32, and the like dispersed or dissolved in a solvent, easily coated microcapsule dispersion. 如果粘合剂层32的材料是液状,只要是使微胶囊20预先分散在粘合剂液中也可以构成涂布液30。 If the material is a liquid adhesive layer 32, as long as the microcapsules 20 are previously dispersed in a binder solution coating liquid 30 may be configured.

微型照相凹版辊40的一部分与涂布液30接触,通过微型照相凹版辊40的旋转,附着在照相凹版图案部42上的涂布液30移到上方侧。 A portion of the micro gravure roll 40 in contact with the coating liquid 30, is rotated by a micro gravure roller 40, adhered to the gravure pattern portion 42 is moved to the upper side of the coating liquid 30.

[基材的移动]如图3所示,在微型照相凹版辊40的上方,分成微型照相凹版辊40的前后,配置前后一对导向辊60。 [Moving substrate] As shown in FIG. 3, above the micro gravure roller 40, is divided into front and rear micro gravure roller 40, the front and rear pair of guide rollers 60 arranged. 导向辊60的下端与微型照相凹版辊40的上端配置在相同或略低程度的位置。 Upper and lower guide roller 60 micro gravure roller 40 arranged at the same level or slightly lower position.

带状基材片材10沿着一方导辊40的下侧连续地供给,经微型照相凹版辊40的上侧,沿另一方导辊40的下侧送出。 Belt-shaped base sheet 10 is continuously supplied along one side of the lower guide roller 40, the upper side of the micro gravure roll 40 along the other side of the lower guide rollers 40 feed. 基材片材10在省略图示的上游侧,把卷绕成辊状的基材片材顺序地拉出移动。 The base sheet 10 on the upstream side (not shown), it is wound into a roll of the base sheet pulled out sequentially moved.

在微型照相凹版辊40的位置,由微型照相凹版辊40对基材片材10施加较小的挤压力,使基材片材10略微朝上改变方向发生变形。 Position micro gravure roller 40, the pressing force exerted by the smaller base sheet 40 for micro-gravure roll 10, the substrate sheet 10 is slightly deformed upward change direction. 把这样轻轻只对基材片材10的一面侧施加压力进行涂布的方式称作吻涂布方式。 Manner so that only lightly applying pressure to one side of the base coated sheet 10 is referred kiss coating method. 从上方压基材片材10的导向辊60,由于处于离开微型照相凹版辊40的位置,因此利用微型照相凹版辊40与导向辊60夹紧基材片材10不需要施加大的力,通过调节导向辊60与微型照相凹版辊40的上下方向的位置差,可以调节施加给基材片材10的压力的大小。 Pressed from above the substrate sheet 10 of the guide roller 60, since at a position away from the micro gravure roller 40, and therefore does not require the use of a large force is applied to the substrate sheet 10 clamped micro gravure roll 60 and the guide roller 40, by adjusting the vertical guide rollers 60 and 40 of the micro gravure roll position difference, magnitude of the pressure regulator 10 can be applied to the substrate sheet.

图3中,基材片材10的移动方向从图的左方向右方移动。 In FIG. 3, the moving direction of the substrate sheet 10 moves from the left to the right direction in FIG. 导向辊60、60的旋转方向是反时针旋转。 Guide rollers 60, 60 rotating direction is counterclockwise. 反之,微型照相凹版辊40的旋转方向也可以设定成反时针旋转。 Conversely, the rotational direction of the micro gravure roll 40 may be set to be rotated counterclockwise. 结果,相对于从图的左方向右方移动的基材片材10,变成与微型照相凹版辊40的外周面从图的右方向左方呈逆向移动。 As a result, with respect to the rightward movement from the left direction in FIG. 10 of the base sheet, into the outer circumferential surface of the micro gravure roll 40 from the left-right direction of FIG was reverse movement. 这样的涂布方向称作逆向涂布方式。 Such a coating is referred to a direction reverse coating manner.

[涂布动作]随着微型照相凹版辊40的旋转,附着在照相凹版图案部42上的涂布液30供给基材片材10的下面进行涂布。 [Coating Operation] With the rotation of the micro gravure roll 40, and deposited on the gravure pattern portion 42 of the coating liquid 30 supplied to the base sheet 10 is coated following. 照相凹版图案部42的凹凸形状高效率地带起含微胶囊20的涂布液30运转。 A gravure pattern of convex shape portion 42 of the high-efficiency areas from a coating solution containing the microcapsules 30 20 operation.

通过适当地设定基材片材10的移动速度与微型照相凹版辊40的旋转速度的关系,在基材片材10的下面按一定的厚度涂布涂布液。 By appropriately setting the relationship between the moving speed of the substrate sheet 10 and the rotational speed of the micro gravure roll 40, below the base sheet 10 by a certain thickness of the coating liquid.

在涂布液30与基材片材10接触位置的略前侧,靠近微型照相凹版辊40的外周面配置刮刀装置50。 In the slightly front side of the coating fluid 10 contacts the substrate sheet 30 and a position close to the micro gravure roll outer circumferential surface 40 of the scraper device 50 arranged. 由贮存器38附着在微型照相凹版辊40上带起的涂布液30,将其厚度调整到相当于刮刀装置50的顶端与微型照相凹版40外周面的间隙后,与基材片材10接触进行涂布。 After the coating solution reservoir 38 is attached at 30 on a micro gravure roller 40 from the tape, which corresponds to the thickness of the gap 40 is adjusted to an outer circumferential surface of the tip of the doctor blade 50 and the micro gravure, the substrate sheet 10 in contact with coating. 因此可以更正确地设定基材片材10上所形成的涂布液30的厚度。 It can be more accurately set the thickness of the coating liquid 30 on the base sheet 10 is formed.

把涂布液30的涂布厚度设定成比微胶囊20的外径略厚的程度。 The coating thickness of the coating liquid 30 is set to be slightly thicker than the outer diameter of the microcapsules 20 degree. 优选不到微胶囊20外径2倍的厚度。 Preferably less than 20 times the thickness of the outer diameter of the microcapsules 2. 因此,最好调节刮刀装置50的顶端位置与进行涂布的微胶囊20的外径一致。 Therefore, the best position of the tip end of the blade means 50 and the outer diameter of the microcapsule coating of uniform 20. 当然,微型照相凹版辊40的旋转数与基材片材10的移动速度也要按照微胶囊20的外径设定在适宜的范围。 Of course, the number of rotation of the moving speed of the substrate sheet 10 micro gravure roller 40 should follow the outer diameter of the microcapsules 20 is set in a suitable range.

此外,若使用通常的照相凹版涂布机进行涂布,使涂布液30从照相凹版辊上移到基材片材10上时,由于利用照相凹版辊与背撑辊夹紧基材片材10,故涂布液30被挤到比基材片材10的幅宽的外侧,有时甚至在基材片材10的背面(上面侧)溢出粘着。 Further, if normal gravure coater coating, the coating liquid 30 to move from the gravure roll on the base sheet 10, since the gravure roll and the backup roller gripping substrate sheet 10, so that the coating liquid 30 is pushed to the outside than the width of the base sheet 10, the back surface adhered sometimes overflow (upper side) of the base sheet 10. 然而,上述实施方案的微型照相凹版涂布机,由于微型照相凹版涂布辊只是轻轻地压基材片材10,故涂布液30难在基材片材10的背面产生溢出粘着问题,如果对涂布液30施加大的压力,也难引起微胶囊20破坏或过度地变形。 However, the above-described embodiment of a micro gravure coater, a micro gravure coating roll since only lightly press the substrate sheet 10, it is difficult to produce a coating liquid 30 overflows sticking problems on the back surface of the substrate sheet 10, If a large pressure is applied to the coating liquid 30, it is difficult to cause the microcapsules 20 destroy or deform excessively.

如图3中虚线所示,使用逆向涂方式的微型照相凹版涂布机,附着在微型照相凹版辊40外周面上的涂布液30,在微型照相凹版辊40与基材片材10的接点处转印在基材片材10上。 3 in dashed lines, a reverse coating method using a micro gravure coater, the coating liquid adhered to the outer circumferential surface 3040 of the micro gravure roll, the gravure roll contacts the micro base 40 and the sheet 10 on the substrate of the transfer sheet 10. 此时,由于基材片材10与微型照相凹版辊40只是轻轻地接触,对微胶囊20不施加过大的压力。 At this time, since the base sheet 10 with the micro gravure roll 40 is only lightly contacting microcapsules 20 without applying excessive pressure. 另外,在上述接点,液布液30从基材片材10与微型照相凹版辊40的两方逆向地拉伸通过施加适度的剪切力而均匀地转印在基材片材10上。 Further, in the contact point, liquid 30 from the liquid distributor base sheet 10 and the micro gravure roll 40 both reverse stretched by applying an appropriate shearing force uniformly transferred onto the base sheet 10. 也难发生微型照相凹版辊40的照相凹版图案转印在基材片材10上所形成的涂布液层上。 Microgravure also less likely to occur gravure roll gravure pattern 40 transferred on the coating liquid layer on the base sheet 10 is formed.

[涂布后的处理]如图5所示,基材片材10上涂布有设定厚度涂布液30的微胶囊担载片材S,使涂布液30干燥后,使微胶囊20牢固地担载在基材片材10上。 [Processing after coating] 5, the base sheet 10 coated with a set thickness of the coating liquid of the microcapsules 30 supporting the sheet S, after drying the coating liquid 30, the microcapsules 20 fixedly supported on the base sheet 10.

使含于涂布液30中的溶剂蒸发,可利用残留的粘合剂使微胶囊20与基材片材10结合。 The solvent contained in the coating liquid 30 is evaporated, the remaining adhesive may be utilized so that the microcapsules 20 to the substrate sheet 10 binding. 合于涂布液30中的粘合剂固化后可形成包埋微胶囊20的粘合剂层32。 After 30 bonded to the coating solution may form a cured binder adhesive layer 32 embedding the microcapsule 20. 为了使微胶囊20与基材片材10结合,或为了使粘合剂层32固化,可以进行吹风干燥处理或加热处理、放射线照射处理等。 The microcapsules 20 to the substrate sheet 10 in conjunction with, or in order to cure the adhesive layer 32 may be blow drying treatment or a heat treatment, radiation exposure treatment.

获得基材片材10上担载有微胶囊20的微胶囊担载片材S后,进行前述的再剥离薄膜12的层合作业。 Obtained on the substrate sheet 10 carrying microcapsules of microcapsules 20 supporting the sheet S, for the peelable layer film 12 cooperate industry.
