Description
本発明は、香料インキ印刷物に関し、さらに詳しくは、紙基材へオフセット印刷及び／又は活版印刷による香料内包マイクロカプセル型インキを使用しても、反りの少ない香料インキ印刷物に関するものである。 The present invention relates to a fragrance ink printed matter, and more particularly, to a fragrance ink printed matter with little warp even when a fragrance-encapsulated microcapsule ink by offset printing and / or letterpress printing is used on a paper substrate.
本明細書において、配合を示す「比」、「部」、「％」などは特に断わらない限り質量基準であり、「／」印は一体的に積層されていることを示す。また、「ＵＶ」は「紫外線」の略語、機能的表現、通称、又は業界用語である。 In the present specification, “ratio”, “part”, “%” and the like indicating the composition are based on mass unless otherwise specified, and the “/” mark indicates that they are integrally laminated. “UV” is an abbreviation, functional expression, common name, or industry term for “ultraviolet light”.
（主なる用途）本発明の香料インキ印刷物の主なる用途としては、雑誌、カタログ、ＰＯＰなどに用いる場合、印刷による紙基材の反りを解消したものである。
しかしながら、紙基材へオフセット印刷及び／又は活版印刷による香料内包マイクロカプセル型インキを使用しても、反りの少なさを必要とする用途であれば、特に限定されるものではない。
(Main use) As a main use of the fragrance ink printed matter of the present invention, when used in magazines, catalogs, POPs, etc., the warp of the paper substrate due to printing is eliminated.
However, even if the perfume-encapsulating microcapsule-type ink by offset printing and / or letterpress printing is used on the paper substrate, there is no particular limitation as long as it is an application that requires little warping.
（背景技術）紙基材に香料インキを印刷した香料インキ印刷物は、特に香料が揮散して香りが急速に失われるので、香りの飛散を防止するために、香料をマイクロカプセル化したインキを用いて印刷するが多い。しかしながら、香料内包マイクロカプセル入り印刷層は比較的厚く、及び／又は紙基材の表面へある程度吸収されるために、印刷後の香料インキ印刷物は、著しく反り（カールともいう）が発生してしまう。この反りは製本、丁合、梱包などの後加工の生産性が低下し高コストとなる。また、観察したり、香料印刷層を爪などで擦って香りを楽しむ際にも、作業しにくいという欠点がある。
従って、香料インキ印刷物は、反りの発生が少なく、低コストで、使用する際にも容易であることが求められている。
(Background Art) Perfume ink prints with perfume ink printed on a paper base material, especially because the perfume is volatilized and the scent is lost rapidly, so in order to prevent the scent from scattering, use the ink in which the perfume is microencapsulated Often print. However, since the perfume-encapsulating microcapsule-containing printing layer is relatively thick and / or absorbed to some extent by the surface of the paper substrate, the perfume ink printed matter after printing is significantly warped (also referred to as curl). . This warpage decreases the productivity of post-processing such as bookbinding, collation, and packing, resulting in high costs. In addition, there is a drawback that it is difficult to work when observing or rubbing the fragrance printed layer with a nail or the like to enjoy the scent.
Therefore, the perfume ink printed material is required to be less warped, low cost, and easy to use.
（先行技術）従来、基材上にクツション層、シート状物層、受容層を順次設けてなり、基材裏面にカール防止処理層を設けて、保存時にカールが発生しない優れた被熱転写シートが知られている（例えば、特許文献１参照。）。しかしながら、カール防止処理層はコーティング法による全面塗布層であり、高価なコーティング機械を用いて、不要な部分まで層を形成するので高コストであるという欠点がある。 (Prior Art) Conventionally, an excellent thermal transfer sheet in which a cushion layer, a sheet-like material layer, and a receiving layer are sequentially provided on a base material, and an anti-curl treatment layer is provided on the back surface of the base material so that no curling occurs during storage. It is known (for example, refer to Patent Document 1). However, the anti-curl treatment layer is a whole surface coating layer formed by a coating method, and has a disadvantage that it is expensive because an expensive coating machine is used to form a layer up to an unnecessary portion.
そこで、本発明は上記のような問題点を解消するために、本発明者らは鋭意研究を進め、本発明の完成に至ったものである。その目的は、紙基材へオフセット印刷及び／又は活版印刷による香料内包マイクロカプセル型インキを使用しても、反りの発生が少なく、低コストで、使用する際にも容易である香料インキ印刷物を提供することである。 In order to solve the above-described problems, the present inventors have made extensive studies and have completed the present invention. The purpose is to produce a perfume ink print that is less likely to warp and easy to use even when using a perfume-encapsulated microcapsule ink by offset printing and / or letterpress printing on a paper substrate. Is to provide.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view of a printed fragrance ink according to one embodiment of the present invention.
FIG. 2 is a cross-sectional view of a printed fragrance ink showing one embodiment of the present invention.
FIG. 3 is a cross-sectional view of a printed fragrance ink showing one embodiment of the present invention.
（香料印刷物）本発明の香料インキ印刷物１０は、図１に示すように、紙基材１１の一方の面に香料内包マイクロカプセル入りの香料印刷層２１を有し、紙基材１１の他方の面の前記香料印刷層２１の相対する部分には印刷層２３を有する。即ち、香料印刷層２１／紙基材１１／印刷層２３の構成で、紙基材１１を挟んで香料印刷層２１と印刷層２３とが対称する構造となるので、反りが極めて発生しにくくなる。 (Perfume printed matter) As shown in FIG. 1, the perfume ink printed matter 10 of the present invention has a perfume printing layer 21 containing perfume-encapsulating microcapsules on one surface of a paper base material 11, and the other of the paper base material 11 A printing layer 23 is provided on a portion of the surface facing the fragrance printing layer 21. That is, in the configuration of the fragrance printing layer 21 / paper base material 11 / printing layer 23, since the fragrance printing layer 21 and the printing layer 23 are symmetrical with the paper base material 11 interposed therebetween, warpage is extremely unlikely to occur. .
（紙基材）紙基材１１としては、具体的には、賦型性、耐屈曲性、剛性等を持たせる基材であり、例えば、強サイズ性の晒または未晒の紙基材、あるいは純白ロール紙、クラフト紙、板紙、加工紙などの紙基材を使用することができる。上記の紙層を構成する紙基材１１の坪量としては特に制限はないが、通常４０〜１０００ｇ／ｍ2程度のもの、好ましくは、６０〜６００ｇ／ｍ2位のものである。 (Paper base material) Specifically, the paper base material 11 is a base material having formability, bending resistance, rigidity, and the like. Alternatively, a paper substrate such as pure white roll paper, kraft paper, paperboard, or processed paper can be used. Although there is no particular limitation on the basis weight of the paper substrate 11 constituting the sheet layer, those generally about 40~1000g / m 2, preferably of the 60~600g / m 2 position.
（香料印刷層）香料印刷層２１は、香料を内包したマイクロカプセルを含むインキを用いて、印刷した層である。通常、香料のマイクロカプセルは粒径が比較的大きいので、シルクスクリーン印刷又はグラビア印刷方式で行われるのが、本発明ではオフセット印刷又は活版印刷で印刷する。該オフセット印刷又は活版印刷での印刷によれば、印圧を高くできるので、被印刷体（紙基材）への良好なインキ転移が得られる。 (Perfume printing layer) The perfume printing layer 21 is a layer printed using ink containing microcapsules containing a perfume. Usually, since the perfume microcapsules have a relatively large particle size, they are printed by silk screen printing or gravure printing. In the present invention, printing is performed by offset printing or letterpress printing. According to the printing by the offset printing or letterpress printing, the printing pressure can be increased, so that good ink transfer to the printing medium (paper substrate) can be obtained.
（マイクロカプセル）マイクロカプセルがインキ練肉時または印刷時の圧力で破壊しないこと、インキに配合したマイクロカプセル中の香料がインキ中に抽出されないことなどから、マイクロカプセルの粒径を１０μｍ以下、好ましくは４〜６μｍにすることが好ましい。 (Microcapsule) The microcapsule has a particle size of 10 μm or less, preferably because the microcapsule does not break at the time of ink kneading or printing, and the fragrance in the microcapsule blended in the ink is not extracted into the ink. Is preferably 4 to 6 μm.
マイクロカプセルに封入される芳香成分は、オレンジ、レモン、ライム、ピーチ等の果物、ばらやラベンダー等の花、ミント、白檀等の香水等から使用目的に応じて好みのものを使用できる。通常、芳香成分は油性または水−アルコール溶性のものである。油性の香料として、具体的な物質名を挙げれば、フェニルエチルアルコール、リナロール、ジャスミン、ヘキシルシナミックアルデヒド、α−リネモン、α−ピネン、ブロムスチロール、シトロネラール、コロラール、テルピオネール、メントール、桂皮酸、等を挙げることができる。 The aromatic component enclosed in the microcapsule can be selected according to the intended use from fruits such as orange, lemon, lime and peach, flowers such as roses and lavender, perfumes such as mint and sandalwood. Usually, the fragrance component is oily or water-alcohol soluble. Specific examples of oily fragrances include phenylethyl alcohol, linalool, jasmine, hexylcinamic aldehyde, α-linemon, α-pinene, bromostyrol, citronellal, coloral, terpionol, menthol, cinnamic acid, Etc.
芳香成分を封入するマイクロカプセルの壁材質は、芳香成分の種類によって異なるが、一般的には、ゼラチン、アラビアゴム、ポリビニルアルコール、エチルセルロース、カルボキシメチルセルロース、ポリウレタン、アルギン酸ナトリウム、尿素・ホルムアルデヒド樹脂、メラミン・ホルムアルデヒド樹脂等のカプセル化できる材料であれば利用できる。カプセル生成手段としては、従来から慣用されている方法、例えば、コアセルベーション法、インサイチュ法、界面重合法、などを用いることができる。 The wall material of the microcapsule that encloses the fragrance component varies depending on the type of fragrance component, but in general, gelatin, gum arabic, polyvinyl alcohol, ethyl cellulose, carboxymethyl cellulose, polyurethane, sodium alginate, urea / formaldehyde resin, melamine Any material that can be encapsulated, such as formaldehyde resin, can be used. As a capsule production | generation means, the method conventionally used conventionally, for example, a coacervation method, an in situ method, an interfacial polymerization method, etc. can be used.
オフセット印刷または活版印刷用香料インキに用いるバインダーは油性のものが好ましいので、水系により製造されることの多いマイクロカプセルは、油性バインダーに練肉分散する前に適切な処理が必要となる。一般に、噴霧乾燥法等により完全に水分を乾燥させるか、フラッシング法等により水系から油系に完全に置換させるか、疎水基と親水基を有する分散剤を用いてバインダー中にカプセルを分散し、その後、水分を完全に除去する方法等が行われる。マイクロカプセルの２次凝集により、カプセル粒子が肥大化しない方法であれば、いずれの方法であってもよい。 Since the binder used in the perfume ink for offset printing or letterpress printing is preferably oily, the microcapsules that are often produced in an aqueous system require appropriate treatment before being kneaded and dispersed in the oily binder. Generally, the moisture is completely dried by a spray drying method or the like, or the water system is completely replaced with an oil system by a flushing method or the like, or the capsule is dispersed in a binder using a dispersant having a hydrophobic group and a hydrophilic group, Thereafter, a method of completely removing moisture is performed. Any method may be used as long as the capsule particles are not enlarged by secondary aggregation of the microcapsules.
溶剤としては、香料インキとしての特性上、無臭性であることが必要であるが、同時にバインダー樹脂や香料に対する溶解性を有し、さらに、香料としての「香り立ち」成分として寄与するものが好ましい。また、溶剤は粘度調整を目的とし、印刷機上で短時間で蒸発しない溶剤が好ましく、非水溶剤、例えば、プロピレングリコール、エチレングリコール、ジエチレングリコール等のグリコール類、プロピレングリコールメチルエーテル等のエーテル類、グリセリン脂肪酸エステル等のエステル類が挙げられる。印刷方式によっては、エタノール等のアルコール類を使用してもよい。 The solvent should be odorless because of its properties as a perfume ink, but preferably has a solubility in a binder resin or perfume and contributes as a “scenting” component as a perfume. . The solvent is preferably a solvent that does not evaporate in a short time on a printing machine for the purpose of viscosity adjustment, and is a non-aqueous solvent, for example, glycols such as propylene glycol, ethylene glycol, diethylene glycol, ethers such as propylene glycol methyl ether, Examples include esters such as glycerin fatty acid esters. Depending on the printing method, alcohols such as ethanol may be used.
（印刷層）印刷層２３は紙基材１１の他方の面（裏面）の香料印刷層２１に相対する部分に設ける。印刷層２３のインキは、特に制限はないが、好ましくは、香料印刷層２１の香料を内包したマイクロカプセルを含まないメジウムインキである。該メジウムインキには透明樹脂と溶剤からなるインキであるが、必要に応じて、充填剤、可塑剤、分散剤、潤滑剤、帯電防止剤、酸化防止剤、防黴剤、などの添加剤を、適宜加えても良く、無色でも有色でもよい。これらの組成物を、分散、混練して、また、必要に応じて、溶剤で固形分量や粘度を調整して、インキ組成物とすればよい。 (Printing layer) The printing layer 23 is provided in the part facing the fragrance | flavor printing layer 21 of the other surface (back surface) of the paper base material 11. FIG. The ink of the printing layer 23 is not particularly limited, but is preferably a medium ink that does not include the microcapsules enclosing the fragrance of the fragrance printing layer 21. The medium ink is an ink composed of a transparent resin and a solvent, and if necessary, additives such as a filler, a plasticizer, a dispersant, a lubricant, an antistatic agent, an antioxidant, and an antifungal agent are added. These may be added as appropriate, and may be colorless or colored. These compositions may be dispersed and kneaded, and if necessary, the solid content and viscosity may be adjusted with a solvent to obtain an ink composition.
通常、オフセット印刷インキ又は活版印刷インキには、酸化重合型インキと紫外線硬化型インキが適用できるが、紙基材への浸透の少ない点から紫外線硬化型インキが好ましい。酸化重合型インキは、油性インキと呼ばれ、ビヒクルの酸化重合による固化、不溶化によって皮膜をつくるもので、乾性油ワニス、乾性アルキドなどがこの部類に入る。酸化促進剤としてコバルトやマンガンが添加されている。 Usually, an oxidation polymerization type ink and an ultraviolet curable ink can be applied to the offset printing ink or letterpress printing ink, but the ultraviolet curable ink is preferred from the viewpoint of little penetration into the paper substrate. The oxidation polymerization type ink is called oil-based ink, and forms a film by solidification and insolubilization of the vehicle by oxidative polymerization. Dry oil varnish, dry alkyd and the like fall into this category. Cobalt and manganese are added as an oxidation accelerator.
紫外線硬化型インキの樹脂形成材料としては、プレポリマーまたはオリゴマーとして、ポリオールアクリレート系、エポキシアクリレート系、ウレタンアクリレート系、ポリエステルアクリレート系、アルキッドアクリレート系、ポリエーテルアクリレート系等、モノマーとしては、モノアクリレート系、ジアクリレート系、トリアクリレート系等を使用したインキが挙げられる。このようなインキを印刷し乾燥して、必要に応じて、温度３０℃〜７０℃で適宜エージングしたり、紫外線硬化型インキは紫外線を照射すれば印刷層２３が形成できる。 As resin-forming materials for UV curable inks, polyol acrylates, epoxy acrylates, urethane acrylates, polyester acrylates, alkyd acrylates, polyether acrylates, etc. as monomers, monoacrylates as prepolymers or oligomers , Inks using diacrylates, triacrylates, and the like. The printing layer 23 can be formed by printing such ink and drying it, and aging as necessary at a temperature of 30 ° C. to 70 ° C., or irradiating the ultraviolet curable ink with ultraviolet rays.
（印刷方法）以上のように、香料印刷層２１及び／又は印刷層２３の印刷方法を公知で一般的な印刷技術であるオフセット印刷及び／又は活版印刷で行うことで、より低コストにすることができる。特に好ましくは、香料印刷層２１及び／又は印刷層２３の印刷を、同じインキ系を用いて、同じ印刷方法で行うことである。同じインキ系とは、香料印刷層２１と印刷層２３の印刷インキが酸化重合インキ又は紫外線硬化インキであり、同じ印刷方法とは、香料印刷層２１と印刷層２３を印刷オフセット印刷又は活版印刷で行うことである。このようにすることで、紙基材１１を挟んだ香料印刷層２１と印刷層２３との対称構造がより正確となるので、反りが極めて発生しにくくなる。もちろん、それぞれを組合わせてもよい。 (Printing method) As described above, the printing method of the fragrance printing layer 21 and / or the printing layer 23 is performed by offset printing and / or letterpress printing, which are known and general printing techniques, to lower costs. Can do. Particularly preferably, printing of the fragrance printing layer 21 and / or the printing layer 23 is performed by the same printing method using the same ink system. The same ink system means that the printing ink of the fragrance printing layer 21 and the printing layer 23 is an oxidation polymerization ink or an ultraviolet curable ink, and the same printing method means that the fragrance printing layer 21 and the printing layer 23 are printed by offset printing or letterpress printing. Is to do. By doing in this way, since the symmetrical structure of the fragrance | flavor printing layer 21 and the printing layer 23 which pinched | interposed the paper base material 11 becomes more exact, curvature becomes very difficult to generate | occur | produce. Of course, you may combine each.
（絵柄）香料印刷層２１と印刷層２３の絵柄は略同一の絵柄とする。印刷層２３の絵柄は、図１に示すように香料印刷層２１と同一でも、図２に示すように香料印刷層２１より大きくても、図３に示すように香料印刷層２１より小さくてもよい。但し、香料印刷層２１と印刷層２３の絵柄とは、表裏それぞれの面から見た場合には鏡像絵柄となるが、一方の面から透視した状態の絵柄をいい、該絵柄が略同一とすればよい。反りに影響のない範囲であれば、表裏での多少の絵柄ズレも許容されるものである。また、香料印刷層２１と印刷層２３の絵柄はそれぞれが、ベタ印刷だけでなく、文字、イラスト、写真、又は網点などでもよい。紙基材１１を挟んだ香料印刷層２１と印刷層２３との対称構造は維持されるので、反りが防止される。 (Picture) The patterns of the fragrance printing layer 21 and the printing layer 23 are substantially the same. The pattern of the printing layer 23 may be the same as the fragrance printing layer 21 as shown in FIG. 1, or larger than the fragrance printing layer 21 as shown in FIG. 2, or smaller than the fragrance printing layer 21 as shown in FIG. Good. However, the pattern of the fragrance printing layer 21 and the printing layer 23 is a mirror image when viewed from the front and back surfaces, but refers to a pattern seen through from one surface, and the patterns are substantially the same. That's fine. As long as it does not affect the warp, some pattern deviation on the front and back is allowed. Further, the patterns of the fragrance printing layer 21 and the printing layer 23 may be not only solid printing but also characters, illustrations, photographs, or halftone dots. Since the symmetrical structure of the fragrance printing layer 21 and the printing layer 23 sandwiching the paper base material 11 is maintained, warping is prevented.
（目止め印刷）紙基材１１と香料印刷層２１、及び／又は紙基材１１と印刷層２３との間に、目止め印刷を行って目止め印刷層を設けてもよい。目止め印刷層は、香料印刷層２１インキ及び／又は印刷層２３インキが紙基材への浸透を抑止するための印刷層である。通常は、無色のメジウムインキを印刷した印刷層が用いられる。メジウムインキは、透明樹脂と溶剤からなるインキで僅かに添加剤が添加される場合もある。現今、オフセット印刷インキまたは活版印刷インキには、酸化重合型インキと紫外線硬化型インキが多用されているが、目止め効果の点からは前記のように紫外線硬化型インキが、紙基材への浸透が少ない点から好ましい。 (Seam printing) The paper substrate 11 and the fragrance printing layer 21 and / or the paper base material 11 and the printing layer 23 may be subjected to eye printing to provide an eye printing layer. The sealing print layer is a print layer for preventing the perfume print layer 21 ink and / or the print layer 23 ink from penetrating into the paper substrate. Usually, a printing layer printed with colorless medium ink is used. The medium ink is an ink composed of a transparent resin and a solvent, and a slight amount of additives may be added. At present, oxidation polymerization type inks and ultraviolet curable inks are frequently used as offset printing inks or letterpress printing inks. However, as described above, ultraviolet curable inks are applied to paper bases in terms of the sealing effect. This is preferable from the viewpoint of low penetration.
酸化重合型インキは、油性インキと呼ばれ、ビヒクルの酸化重合による固化、不溶化によって皮膜をつくるもので、乾性油ワニス、乾性アルキドなどがこの部類に入る。酸化促進剤としてコバルトやマンガンが添加されている。紫外線硬化型インキの樹脂形成材料としては、プレポリマーまたはオリゴマーとして、ポリオールアクリレート系、エポキシアクリレート系、ウレタンアクリレート系、ポリエステルアクリレート系、アルキッドアクリレート系、ポリエーテルアクリレート系等、モノマーとしては、モノアクリレート系、ジアクリレート系、トリアクリレート系等を使用したインキが挙げられる。着色インキの場合は、これに体質顔料や色材としての有機顔料等が添加されるが、目止め材として用いる場合は、顔料等を添加しないメジウムインキとして使用する。 The oxidation polymerization type ink is called oil-based ink, and forms a film by solidification and insolubilization of the vehicle by oxidative polymerization. Dry oil varnish, dry alkyd and the like fall into this category. Cobalt and manganese are added as an oxidation accelerator. As resin-forming materials for UV curable inks, polyol acrylates, epoxy acrylates, urethane acrylates, polyester acrylates, alkyd acrylates, polyether acrylates, etc. as monomers, monoacrylates as prepolymers or oligomers , Inks using diacrylates, triacrylates, and the like. In the case of a colored ink, an extender pigment, an organic pigment as a coloring material, or the like is added thereto, but when used as a sealing material, it is used as a medium ink without adding a pigment or the like.
目止め印刷層を設けた香料印刷層２１は、オフセット印刷及び／又は活版印刷で紙基材へ印刷しても、着肉量が多く、紙基材への香料インキの浸透もないので、十分な香りが得られる。また、目止め印刷層を設けた印刷層２３は、より反り防止効果に優れる。 The perfume printing layer 21 provided with the sealing print layer is sufficient because even if printing is performed on a paper substrate by offset printing and / or letterpress printing, the amount of fleshing is large and the perfume ink does not penetrate into the paper substrate. A fragrance can be obtained. Moreover, the printing layer 23 provided with the sealing printing layer is more excellent in the warp prevention effect.
