Abstract
本发明是以在原纸上附加上含有颜料与胶合剂胶层的颜料胶层上，附加上含有对玻璃传导热度80℃以上的热可塑性共聚物100重量部(重量百分比)，如苯乙烯和丙烯酸类的聚合物、链烯烃系的聚合物或苯乙烯和马来酸类的聚合物的表面上胶剂3～100重量部(重量百分比)的表面层，其一种感光度高、墨水着色均匀、墨水干燥性良好、表面剥离强度等十分适合用于印刷；也不附着于压光机辊轴且可优异地制造出的印刷用胶纸。
Description
技术领域
本案发明是有关于一种适合用于印刷的高感光度优良胶纸。更详加说明的，本发明是有关于表面层涂布热可塑性共聚合体与表面上胶剂的混合液并干燥时，着色不会不均、墨水干燥性、表面剥离强度等十分适合印刷的实用性的发明。
背景技术
现今，其表面涂有颜料及其胶合剂的涂层纸作为高级印刷用纸被广泛使用，除了表面墨水的吸收性及其表面着墨强度等之外，印刷纸表面的感光度也是考虑印刷纸好坏的重要因素。但问题是，为了提高用纸的感光度而加压用纸表面使其变平滑后，势必表面空隙会减少，墨水的吸收度变会随之下降。再者，为了提高感光度而大量使用作为颜料胶合剂的含有水溶性或水分散性高分子共聚物的表面上胶剂后，表面着墨强度及感光度是确实提升了，但也因为原纸表面空隙减少的缘故，墨水的吸收性会下降，要同时拥有感光度和易于印刷这两样特性着实有其困难性存在。也因此，为了在高感光度又适合印刷中取得平衡点，虽然颜料或胶合剂的种类及搭配，涂料的涂抹量及平滑处理的程度已有固定，但为了追求更适合印刷的高感光度印刷用纸就必须要有其它更进一步的技术才行。印刷用纸的感光度通常分为微胶纸、涂层纸(coating)、铜版印刷纸、超级铜版印刷纸和抛胶纸(cast coated)，依序感光度越高，本案期待以发明出与超级铜版印刷纸均等甚至拥有比其更高的感光度为目标，因此本案在此所指的高感光度印刷纸指的便是拥有高于超级铜版印刷纸感光度的印刷用胶纸。
习知用铸压光机来制造高感光印刷纸。此方法是在湿润涂布颜料及胶合剂的印刷纸表面上以镜面铸压光辊加热乾燥的方法，其缺点为较一般铜版印刷纸、涂层纸或微胶纸制造的速度缓慢许多。
又，不使用铸滚轴，而是利用加热压光机来处理的方法也广为人知。例如，特开昭56-68188号公报、特公昭64-10638号公报、特公昭64-11758号公报中便揭示出将颜料及胶聚合物或水溶性高分子树脂混合涂布干燥后的涂工层以加热压光机来加以处理的方法。这些是在印刷纸表层以玻璃化温度5℃或38℃以上的胶聚合物加以涂布，然后以加热压光机来使其表层涂布层的温度高于所使用胶聚合物玻璃化温度的一种方法。这种方法是很简单方便的，生产性优良，很适合普通涂层纸的制造，但是以感光度这点来说却略显不足，别说比不上涂层纸，也很难制作出比超级铜版印刷纸更好的成品，无法拥有如涂层纸那样般的感光度。
再者，其它的方法还有如特开昭59-22683号公报所揭示的方法。此种方法是在附有薄板或颜料涂工层的机板上以两种以上不同造膜温度的胶聚合物涂布，使其干燥，然后依必要程度运用压光机来使其表面平滑的技术。借由两种不同最低造膜温度的胶聚合物的混合并用使其干燥后，印刷纸表面会产生不至于影响感光度的些微裂缝，使其制作出的成品也能有不错的墨水吸收性。此技术着重的要点便是能使涂布表面层能产生些微的裂缝，也因此仔细注意其干燥条件是很重要的一环。亦即，干燥条件必须设定成最低造膜温度较低的乳胶完全溶解，而较高者仅部份溶解才行。但，众所周知地，干燥条件通常会因许多因素而常改变，此种技术如以是否适用于工业上来考虑，要使整个制作过程中其干燥条件常保平均、一定的水准实际上是不太可能的。也因此，要保持一定水准的品质可以说非常地困难。
本发明研究者们，如特开平3-167396号公报、特开平8-13390号公报中所揭示，在机台上设有涂工层的基材颜料涂工层上赋予其拥有二次传导温度80℃以上的热可塑性聚合物<即含有热可塑性的聚合物或由共聚物所组成的感光乳胶剂>而得其印刷用原纸。此种成品不需经过平滑处理就能拥有如涂层纸般的光泽。且吸墨性强，表面强度等印刷适合度颇高。更甚，以胶聚合物二次传导以下的温度来进行压光机的处理方法，能得到比超级铜版印刷纸更高的感光度，同时，其吸墨性、表面强度及点误差率(misdot)等等的印刷适合度高，可以说非常的实用。也因为不会产生附着压光机辊轴的情形发生，可预见其生产性增高与高效能生产的远景。但，当连续印刷时，会发生着色不均、不利印刷的情形，与压光机辊轴剥离不均匀等问题。
发明内容
有鉴于上述发生的状况，本案发明是以提供一种白纸高感光度、吸墨性佳、表面张度优良、特别是连续印刷时不会产生着色不均的情形、墨水干燥性良好适合印刷的高感光度印刷纸以及提供能以简单且低价的方法来制造出拥有一定水准品质的印刷用胶纸为其课题目标。
本案发明是以在附有颜料涂工层的基材颜料涂工层上再赋予一层含有玻璃化温度80℃以上的热可塑性聚合物与上胶剂混合物的表面层，而得到一种附有高感光度、吸墨性佳、表面强度优良、不会发生着色不均现象的非常适合印刷的印刷用胶纸，使其能以低价制造出与压光机辊轴剥离性佳，有一定水准品质的产品。本案发明的表面层，热可塑性聚合物100％比上胶剂3～100％为理想的搭配，更理想的是上胶剂含3～50％，最理想的为上胶剂3～20％的比例。
借由加上本案发明的表面层而能得高感光度的理由是因为透过利用玻璃化温度80℃以上的热可塑性聚合物与上胶剂的混合剂，使这些上胶剂将大部分颜料涂工层的下凹部分填满，其表层能呈现光滑平坦的缘故。
因如果表面层仅由热可塑性聚合物构成的话，在墨水转印纸面时，会产生吸墨不平均的现象，墨水的干燥性也随之不平均，墨水较晚干燥的部分会因后次印刷橡皮布(blanket)的非划线部中的不均一逆移转产生逆叠印(back trapping)，因此发生印刷表面墨水不均匀的现象。又，如果表面层仅由上胶剂构成的话，墨水转印至纸面后较慢干燥，实不利于印刷作业上。本案发明是借由玻璃化温度高温的热可塑性聚合物与上胶剂的混合，不需牺牲纸面的质性，也不会产生墨水不均匀的现象，墨水干燥性也能保持一定的水准。
能克服问题拥有如此多优点的原因在于相对于仅使用热可塑性聚合物的表面层会产生因表面层空隙不均匀吸墨的情形，本发明再借由添入上胶剂使其本有的空隙部分得以填补，墨水的浸透性也才能够更加地平均一致。
具体实施方式
本案发明的相关基本素材为了能同时兼有高感光度及适合于印刷的特性，在原纸上赋予其一层涂有颜料及胶合剂的颜料涂工层是不可欠缺的一环。就原纸来说，只要是有附颜料涂工层的均能使用，中等纸或高级纸、新闻纸、片艳纸、特别照相凹板纸等等非涂工纸均能使用。在非涂工纸类上上一层颜料涂工层的方法仅只需普通制作颜料涂工纸的做法就可完成。依所需的品质适当地调整涂料中颜料、胶合剂的种类及用量即可。
本案发明颜料涂工层中所使用的颜料，以往皆是使用如高岭土、粘土、细层粘土(delaminated)、重质碳酸钙、轻质碳酸钙、滑石、二氧化钛、硫酸钡、硫酸钙、氧化铅、硝酸、硝酸盐、人造纤硅石胶、缎光白(stain white)等无机颜料及塑料颜料等有机颜料等，以单独或两种类以上混合使用。但为提高高光泽印刷适应度，以100重量部颜料配合50重量部以上的高岭土为理想。
本案发明颜料涂工层中所使用的胶合剂，以往皆是使用如苯乙烯·顺丁二烯酸共聚物、苯乙烯·丙烯酸共聚物、乙二烯二酸、顺丁烯二酸甲基、乙烯/丁基丙烯酸等各种共聚物及聚乙烯醇、无水顺丁烯二酸共聚物、丙烯酸、甲基丙烯酸甲酸类共聚物等的合成胶合剂以及酪蛋白、大豆蛋白、合成蛋白的蛋白质、氧化淀粉、阳性淀粉、尿素磷酸酯化淀粉、羟乙基化淀粉等酯化淀粉、糊精等淀粉类、羰基乙基纤维素、羟基乙基纤维素、羟基甲基纤维素衍生物等，适当选择一种以上这些普遍用于涂纸的胶合剂为其使用方法。此胶合剂以是每100％颜料配以5～50％的用量，5～25％用量范围为佳。特别是为求良好墨水干燥性，苯乙烯和丁二烯的聚合物乳胶可配合颜料100重量控制在13重量部以下。又，在必要时也可斟酌搭配上分散剂、增粘剂、保湿剂、消泡剂、耐水化剂、着色剂、印刷适性提升剂等普通用于涂纸的组成物质来使用。
原纸上的颜料涂工层可以在原纸的单面或双面、或以单层或双层来加以涂抹附加。本发明的涂抹层的涂量，单面2～40g/m2为理想，5～25g/m2更理想，而以8～20g/m2为最理想。
原纸上表面处理剂的涂布方法除了有利用2辊式压胶机、浇口辊涂机、刮刀计数压胶机、棒型仪表转换压胶机、气动刮涂机等的膜转印型辊涂机、平坦夹压/叶片(blade)压胶机、喷泉式/刮刀涂布机、短式平面应用式压胶机等之外，还有代换金属板片而改以凹槽或平面棒代替的棒涂机、帘式涂布机、铸膜涂机等众所周知之压胶机等也可使用。
本案发明在原纸上涂抹上表面处理剂后需在表面再上层由热可塑性聚合物及上胶剂所组成的混合液。在上此混合液之前，也可利用超级压光机、光泽压光机、或高温夹软辊压光机等来使其表面平滑。
本案发明中涂布于表面层的热可塑性聚合物含有热可塑性聚合体或感光乳胶的共聚物，附有玻璃化温度80℃以上的温度，即使是经由热风干燥或压光机处理过后也能保持其微粒状态。在模芯壳体型的情况下，壳体部分的玻璃化温度高达80℃以上。拥有80℃以上的玻璃化温度的话，便不用限制构成其聚合物或共聚物的单元素种类及制造方法。理想的单元素有如苯乙烯及其衍生物、氯化亚乙烯基、丙烯酸或甲基丙烯酸酯等。热可塑性聚合物的玻璃化温度并无特别的上限，主要是以制造热可塑性聚合物时所使用单元素的种类及可塑剂等的添加剂来决定，通常温度最高可达130℃。如使用传导温度80℃以下的聚合物或共聚物的话，所制出纸质的感光度会偏低，使用压光机延压时也易发生与延压棒分离不平均的问题。再者，在考虑过高感光度及表面强度两特性之后，本案发明的热可塑性聚合物的大小以平均颗粒直径100nm以下为最理想。
本案表面层所使用的表面上胶剂，可为苯乙烯和丙烯酸类、苯乙烯和马来酸类、苯乙烯和异丁烯酸类、链烯烃系、尿烷系等聚合物，单独使用或并用并无特限。此上胶剂为溶液型态，或乳胶型态亦可，经热风干燥处理或压光机处理后不具粒子形状者。其聚合平均分子量为1000～500000为理想，其中以苯乙烯和丙烯酸类、链烯烃系、或苯乙烯马来酸系共聚合物为理想，特别以苯乙烯丙烯酸系上胶剂者可得更高白纸光泽度。
本案发明是以在原纸表面处理剂上，将热可塑性聚合物与上胶剂混合后的液体涂布于其上的方法，在不破坏本案发明宗旨范围内，适宜地添加为了调节本案发明的表层涂液的表面强度所使用的一般用天然或合成树脂的胶合剂、涂抹时为了更适合涂抹所调节添加的流动调节剂或消泡剂、为了减少使用更种压光机时发生附着延压棒所添加的脱模剂、以及为了使涂布表面上色所使用的着色剂等均可一并当作表层涂液来使用。热可塑性聚合物与表面上胶剂干燥固定后以80～100重量％为其理想。以此重量％的表面层涂液适量分布于表面处理剂上便是本案发明的主要内容。涂抹量依所希望的纸质性质可适时地调节，但涂抹量过多的话，除了成本提高外，吸墨性下降、调节不均衡后，表面强度下降等不理想的状况也会随之而来。因此，涂抹过多绝非良策，普通大概单面0.1g/m2以上，0.3～3g/m2的涂量为最理想。
表层的涂工手法，普通常用的压胶机、辊式压胶机、压缩刀刃型压胶机、棒涂机、凹板压胶机、浇口辊涂机等均可使用。使用本案发明的热可塑性聚合物时，涂抹后的干燥作业不需要特定的设定条件，只要如普通涂层纸的干燥条件就能有最佳的表面层。如此制作下来的印刷用胶纸再经过压光机处理之后，就可得到比超级铜版印刷纸拥有更高感光度的印刷用优良纸。而至于选用的压光机方面，普通使用于使涂层纸平滑的超级压光机、夹光泽压光机、高温软辊压光机等均可一并使用。本案发明即使金属棒的温度于100℃或150℃以上进行延压处理其表面与延压棒之间的剥离性也很良好。
再者，即使不使用压光机加以处理，也能制作出白纸高感光度的印刷用胶纸。

由以上在实施例、比较例中所使用的热可塑性聚合物与上胶剂所得的涂布印刷用纸的品质评价试验，结果如表1所示。
【表1】
参考：市面贩售抛光OK爱娜美丽怀特(enamel white)(王子制纸(股份)制)的白纸光泽度 87％市面贩售超级铜版纸sA金藤(王子制纸(股份))的白纸光泽度 80％
表1横栏所记载的评价项目与试验方法如下所示。
*玻璃化温度··以20℃、65％(相对湿度)来制表，其中20mg是以仪表热量测试装置<DSC6200R：Seiko Instruments Inc.(股份)制>以升温速度为5/min，测定温度0～100所得的特性曲线所算出。
*白纸感光度··使用村上式光泽计(glossmeter)，以反射角75°测定的。
*墨水干燥性··使用RI-II机型测验式打印机印刷，将印刷后的印刷表面以白纸附印，以其墨水转印于白纸的多寡来评断墨水的干燥性能。极少墨水转印于白纸上时即评定为○，墨水转印现象显著时则评为×。
*着色不匀··使用胶印四色片型印刷机<MAN ROLAND公司制，R304>，在其墨水添加高回响(high echo)M<东洋墨水公司制>以8000张/时的速度印刷时，视其是否会产生呈蓝色的不均匀现象来判断。无不均匀现象者评定为○，产生少许不匀现象者评定为△，不匀现象显著时则评为×。
*与压光辊的剥离性··以使用压光机时，目视金属棒表面上有无附着物<表面上胶剂等>来评断。金属棒表面无附着物剥离性良好者评定为○，金属棒上看得到少许附着物，未完全剥离者评定为△，金属棒表面的附着物显著、剥离性不良时则评为×。
从表1我们可以很明显得知，本案发明的印刷用纸均具有非常高的感旋光性。着色均匀、墨水干燥性等印刷适合度方面也很优良，可以说是非常的实用。
而相对于此，比较范例则均具有感光度不足，或发生着色不均匀、墨水干燥缓慢等问题，由此可知比较范例均不能达到本案发明的目的。
依照本案发明，在基材上设置颜料涂工层，并在此上涂布含有玻璃化温度80℃以上的热可塑性共聚物及上胶剂的混合液后，使其干燥形成一层表层即可。再加上，其着色均匀、墨水干燥性、表面剥离强度等的印刷适合度优良，非常的实用，也不会产生附着压光辊的情形，生产性能十分优良的发明。
