本発明は、インクジェット記録材料に関するものであり、特に顔料インクに適したインクジェット記録材料に関するものである。 The present invention relates to an ink jet recording material, and more particularly to an ink jet recording material suitable for pigment ink.
近年、インクジェットプリンターやプロッターの目ざましい進歩により、フルカラーでしかも高精細な画像が容易に得られるようになってきた。 In recent years, due to remarkable progress of inkjet printers and plotters, it has become possible to easily obtain full-color and high-definition images.
インクジェット記録方式は、種々の作動原理によりインクの微小液滴を飛翔させて紙等の記録材料に付着させ、画像・文字等の記録を行うものである。インクジェットプリンターやプロッターはコンピューターにより作成した文字や各種図形等の画像情報のハードコピー作成装置として、種々の用途において近年急速に普及している。特に多色インクジェット方式により形成されるカラー画像は製版方式による多色印刷やカラー写真方式による印画に比較しても遜色のない記録を得ることが可能であり、さらに作成部数が少ない用途においては、印刷技術や写真技術によるよりも安価で済むことから広く応用されつつある。 The ink jet recording system records images, characters, and the like by causing micro droplets of ink to fly and adhere to a recording material such as paper according to various operating principles. Inkjet printers and plotters are rapidly spreading in various applications in recent years as hard copy creation apparatuses for image information such as letters and various graphics created by a computer. In particular, color images formed by the multi-color ink jet method can obtain a recording that is comparable to multi-color printing by the plate-making method and printing by the color photographic method. It is being widely applied because it requires less cost than printing and photographic techniques.
さらに、用途の多様化に伴い、大判のポスターやPOPアート、製図用途に使用されることが多くなってきている。これら用途ではインクジェットの高鮮鋭性を活かせ、色彩性も優れていることから、良好な画像を得ることが可能であり、宣伝効果が大きいものとなる。これらへの適用はパーソナルコンピュータレベルで、鮮鋭性や色彩性といった画像再現性や色再現性に優れた画像を簡単に得ることが可能であるためであり、インクジェット記録材料を多用する理由ともなっている。 Furthermore, with the diversification of uses, it is increasingly used for large-format posters, POP art, and drafting. In these applications, since the high sharpness of the ink jet is utilized and the color is excellent, a good image can be obtained and the advertising effect is great. Application to these is because it is possible to easily obtain an image with excellent image reproducibility and color reproducibility such as sharpness and color at the personal computer level, which is also a reason for using a lot of ink jet recording materials. .
これらインクジェット記録装置の高性能化や用途の多様化により、インクジェット記録に対するニーズは高まっており、その結果記録装置或いはインクジェット記録材料に求められる特性も要求もかなり高度になってきている。例えば、大判ポスターやPOPアート、また写真画像を出力する用途の場合、その用途が屋内外の展示や個人の記録保存といったものであるため、従来以上に画像の耐候性、画像保存性が求められるようになっている。このような要望に対し、インク及びインクジェット記録材料の改良が進んでおり、従来よりはかなり良好な保存性が得られるようになってきている。しかしながら、特に耐光性に関しては未だ銀塩写真のレベルには到達しておらず、要求が満たされていないのが現状である。 Due to the high performance and diversification of applications of these ink jet recording apparatuses, the need for ink jet recording has increased, and as a result, the characteristics and requirements required for the recording apparatus or ink jet recording material have become considerably high. For example, in the case of applications such as large posters, POP art, and photographic image output, the applications are for indoor / outdoor exhibitions and personal record storage, and thus weather resistance and image storage stability are required more than before. It is like that. In response to such demands, improvements in ink and ink jet recording materials are progressing, and considerably better storability can be obtained than before. However, in particular, the light resistance has not yet reached the level of silver salt photography, and the current situation is that the requirements are not satisfied.
このような要求を満たすために、最近では顔料タイプのインクが使用されるようになってきている。顔料インクは光劣化も少なく、水によって再溶解しないため、染料タイプのインクよりも耐候性、画像保存性が向上することが知られている。しかし、インク中の色材顔料は染料と異なり溶媒に不溶であるため、インク中の色材顔料を安定に分散させる必要があり、インク中の色材顔料の比率を容易に上げられない。また、染料インクのように着色効率が高くなく、鮮明な発色を得にくい。 In order to satisfy such demands, pigment type inks have recently been used. It is known that the pigment ink has little light deterioration and does not re-dissolve with water, so that the weather resistance and the image storage stability are improved as compared with the dye type ink. However, since the color material pigment in the ink is insoluble in the solvent unlike the dye, it is necessary to stably disperse the color material pigment in the ink, and the ratio of the color material pigment in the ink cannot be easily increased. In addition, the coloring efficiency is not high like dye ink, and it is difficult to obtain a clear color.
そのため、インクジェット記録材料に対する要求も必然的に高まってきている。顔料インクの吸収性を向上させる方法として、支持体上に塗工するインク受理層を厚くすることが考えられる。この方法でインク吸収性は改善されるが、インクが原紙方向に深く浸透するため、発色性が低下する。前述したように顔料インクの場合、染料インクと比較して鮮明な発色を得にくいため、インクが深く浸透すると発色性は著しく低下してしまう。さらにインク受理層を有しないインクジェット記録材料ではさらにその低下は著しい。 Therefore, the demand for ink jet recording materials is inevitably increasing. As a method for improving the absorbability of the pigment ink, it is conceivable to increase the thickness of the ink receiving layer to be coated on the support. Ink absorption is improved by this method, but the color develops because the ink penetrates deeply in the direction of the base paper. As described above, in the case of the pigment ink, it is difficult to obtain a clear color compared with the dye ink, so that the color developability is significantly lowered when the ink penetrates deeply. Furthermore, the decrease is further remarkable in the ink jet recording material having no ink receiving layer.
これらインクジェット記録材料は、良好なインクジェット記録性能を得る等の目的で、無機超微粒子を含有するインクジェット記録材料が提案され、一次粒子径が3nm〜30nmである主として気相法による合成シリカを使用するインクジェット記録材料が開示されている(例えば、特許文献1、2参照)。 For these ink jet recording materials, for the purpose of obtaining good ink jet recording performance, an ink jet recording material containing inorganic ultrafine particles has been proposed, and synthetic silica mainly having a primary particle diameter of 3 nm to 30 nm is used by a gas phase method. An ink jet recording material is disclosed (for example, see Patent Documents 1 and 2).
また、非吸収性支持体上に無機超微粒子、ポリビニルアルコール及びホウ酸またはその塩を含有させた塗層を設ける方法が提案されている(例えば、特許文献3〜5参照)。この方法によれば、塗層の乾燥塗工量が少ない場合には、ひび割れを発生させずに塗層を得ることができるが、インクの吸収性が低くく、インク吸収性を向上させるために厚い塗層を設けるには、塗液を室温以上に加温した後に塗工する、もしくは塗工後に冷却する等して、塗液を支持体上でセットさせ、粘度増加剤と無機超微粒子やバインダーと強固な結合を形成させた後、乾燥を行わなければならないため、生産効率が低下するうえ、塗層を厚くしてもインク吸収性は満足のいくものではないことがある。 Moreover, the method of providing the coating layer which contained the inorganic ultrafine particle, polyvinyl alcohol, boric acid, or its salt on the non-absorbable support body is proposed (for example, refer patent documents 3-5). According to this method, when the dry coating amount of the coating layer is small, the coating layer can be obtained without causing cracks, but the ink absorbency is low and the ink absorbability is improved. In order to provide a thick coating layer, the coating solution is heated after being heated to room temperature or higher, or cooled after coating, and the coating solution is set on the support, and a viscosity increasing agent and inorganic ultrafine particles or Since it is necessary to dry after forming a strong bond with the binder, the production efficiency is lowered, and even if the coating layer is thickened, the ink absorptivity may not be satisfactory.
インクの吸収性を向上させるために下層にシリカ多孔質層を設け、上層にアルミナまたはアルミナ水和物含有層を有するインクジェット記録材料や下層に吸収性顔料含有層、最表層に擬ベーマイトを配した記録材料が提案されている(例えば、特許文献6、7参照)。 In order to improve the ink absorbency, a porous silica layer is provided in the lower layer, an ink jet recording material having an alumina or alumina hydrate-containing layer in the upper layer, an absorbent pigment-containing layer in the lower layer, and pseudoboehmite in the outermost layer. Recording materials have been proposed (see, for example, Patent Documents 6 and 7).
この様な無機超微粒子を含有する光沢発現層の塗液をシリカ多孔質からなる下層上に塗工・乾燥する方法で形成する場合、光沢発現層中のバインダー成分等が吸水性高い下層への落ち込みが発生するため、光沢発現層表面にひび割れが生じやすく、染料インクにおいては、そのひび割れが多いためにインクの吸収性の向上は見られるが、染料インクに比べ発色性の低い顔料インクにおいては、そのひび割れに顔料インクが落ち込むことにより顔料インク特性が低下することがある。 When forming a coating liquid for such a glossy layer containing inorganic ultrafine particles on the lower layer made of silica, and drying it, the binder component in the glossy layer is applied to the lower layer with high water absorption. Due to the occurrence of depression, cracks are likely to occur on the surface of the glossy layer, and in dye inks, there are many cracks, so the ink absorption is improved, but in pigment inks that have low color development compared to dye inks When the pigment ink falls into the cracks, the pigment ink characteristics may deteriorate.
一方、アルミナあるいは、アルミナとコロイダルシリカを含有するインク受理層にメタクリル酸エステル−メタクリル酸ジメチルアミノアルキルエステル−スチレン共重合物を配合するインクジェット記録材料が提案されているが、キャストコート法を用いたインクジェット紙において光沢性の改善を目的としているため、インク受理層表面のひび割れ、あるいは顔料インクの発色性の点では不十分であった(例えば、特許文献8、9参照)。
本発明の課題は、インク受理層表面にひび割れを生じさせずに顔料インクの高い吸収性と発色性を兼ね備えたインクジェット記録材料を提供することにある。 An object of the present invention is to provide an ink jet recording material that has both high absorbability and color developability of pigment ink without causing cracks on the surface of the ink receiving layer.
上記目的を達成するために鋭意研究を重ねた結果、支持体の少なくとも片面にアルミナ水和物を主成分とするインク受理層の塗液を塗工・乾燥して形成されるインクジェット記録材料において、該インク受理層中に少なくともポリビニルアルコール、メタクリル酸エステル−メタクリル酸ジメチルアミノアルキルエステル−スチレン共重合物、ホウ酸またはホウ酸塩、及び硝酸、酢酸、塩酸から選ばれる1種以上の酸を含有するインクジェット記録材料により解決した。 As a result of intensive research to achieve the above object, in an ink jet recording material formed by applying and drying a coating liquid of an ink receiving layer mainly composed of alumina hydrate on at least one side of a support, The ink-receiving layer contains at least polyvinyl alcohol, methacrylic acid ester-dimethylaminoalkyl methacrylate methacrylate-styrene copolymer, boric acid or borate , and one or more acids selected from nitric acid, acetic acid, and hydrochloric acid . Solved by inkjet recording material.
該支持体と該インク受理層の間に顔料層を設けることがより好ましい。 More preferably, a pigment layer is provided between the support and the ink receiving layer.
本発明のインクジェット記録材料は、インク受理層にひび割れが無く、高い顔料インクの吸収性と発色性を兼ね備える。 The ink jet recording material of the present invention does not have cracks in the ink receiving layer and has both high pigment ink absorbability and color developability.
以下、本発明のインクジェット記録材料を詳細に説明する。 Hereinafter, the ink jet recording material of the present invention will be described in detail.
本発明者は、顔料インク適性を向上させる方法として、顔料インク中の溶媒と色材顔料とを分離し、顔料インク中の色材顔料をインク受理層表面近傍に分布させることで、吸収性と発色性の改善が可能であると考えた。 As a method for improving the suitability of the pigment ink, the present inventor separated the solvent and the color material pigment in the pigment ink and distributed the color material pigment in the pigment ink in the vicinity of the surface of the ink receiving layer. We thought that color development could be improved.
そこで本発明者らはインク受理層表面のひび割れをなくし、顔料インク中の色材顔料成分と溶媒分を分離する手法を鋭意検討した結果、アルミナ水和物を主成分とするインク受理層中に少なくともポリビニルアルコール、メタクリル酸エステル−メタクリル酸ジメチルアミノアルキルエステル−スチレン共重合物、ホウ酸またはホウ酸塩、及び少なくとも硝酸、酢酸、塩酸から選ばれる1種以上の酸を含有するすることで、ひび割れのないインク受理層を設けることが可能となり、効果的に顔料インクを色剤顔料と溶媒分に分離し、顔料インクの吸収性と発色性を兼ね備えたインクジェット記録材料を作製できることを見いだした。 Therefore, the present inventors have intensively studied a method for removing the colorant pigment component and the solvent component in the pigment ink by eliminating cracks on the surface of the ink receiving layer, and as a result, in the ink receiving layer mainly composed of alumina hydrate. By containing at least one acid selected from polyvinyl alcohol, methacrylate ester-dimethylaminoalkyl methacrylate methacrylate-styrene copolymer, boric acid or borate , and at least nitric acid, acetic acid, hydrochloric acid , and cracking It has been found that an ink receiving layer can be provided, and the pigment ink can be effectively separated into a colorant pigment and a solvent, and an ink jet recording material having both the absorbability and color developability of the pigment ink can be produced.
本発明でいう顔料インクとは、色材顔料、分散溶媒、その他の添加剤等からなる記録液体であり、特に限定されない。また、分散溶媒は、水または各種有機溶剤のいずれを用いたものでも良い。 The pigment ink as used in the present invention is a recording liquid comprising a colorant pigment, a dispersion solvent, other additives, and the like, and is not particularly limited. Moreover, the dispersion solvent may use either water or various organic solvents.
以下に本発明に係わるインク受理層について説明する。 The ink receiving layer according to the present invention will be described below.
本発明のインク受理層には、アルミナ水和物が主成分として用いられる。 In the ink receiving layer of the present invention, alumina hydrate is used as a main component.
本発明において、主成分とは、インク受理層に含有される顔料の総量の50質量%以上であることを表す。 In the present invention, the main component represents 50% by mass or more of the total amount of pigments contained in the ink receiving layer.
本発明に用いられるアルミナ水和物は、下記の一般式により表すことができる。Al2O3・nH2Oアルミナ水和物は組成や結晶形態の違いにより、ジプサイト、バイアライト、ノルストランダイト、ベーマイト、ベーマイトゲル(擬ベーマイト)、ジアスポア、無定形非晶質等に分類される。中でも、上記の式中、nの値が1である場合はベーマイト構造のアルミナ水和物を表し、nが1を越え3未満である場合は擬ベーマイト構造のアルミナ水和物を表し、nが3以上では非晶質構造のアルミナ水和物を表す。特に、本発明に好ましいアルミナ水和物は、少なくともnが1を越え3未満の擬ベーマイト構造のアルミナ水和物である。 The alumina hydrate used in the present invention can be represented by the following general formula. Al 2 O 3 · nH 2 O alumina hydrate is classified into gypsite, vialite, norstrandite, boehmite, boehmite gel (pseudoboehmite), diaspore, amorphous amorphous, etc., depending on the composition and crystal form. The In particular, in the above formula, when the value of n is 1, it represents an alumina hydrate having a boehmite structure, and when n is more than 1 and less than 3, it represents an alumina hydrate having a pseudo boehmite structure, where n is 3 or more represents an amorphous alumina hydrate. In particular, the preferred alumina hydrate for the present invention is an alumina hydrate having a pseudo boehmite structure in which at least n is more than 1 and less than 3.
本発明に用いられるアルミナ水和物の形状は、平板状、繊維状、針状、球状、棒状等のいずれでもよく、インク吸収性の観点から好ましい形状は平板状である。平板状のアルミナ水和物は、平均アスペクト比3〜8であり、好ましくは平均アスペクト比が3〜6である。アスペクト比は、粒子の「厚さ」に対する「直径」の比で表される。ここで粒子の直径とは、アルミナ水和物を電子顕微鏡で観察したときの粒子の投影面積に等しい円の直径を表す。アスペクト比が上記の範囲より小さい場合は、十分なインク吸収性が得られない場合がある。一方アスペクト比が上記の範囲を超える場合は、粒子を揃えてアルミナ水和物を製造することが困難となる。 The shape of the alumina hydrate used in the present invention may be any of a flat plate shape, a fiber shape, a needle shape, a spherical shape, a rod shape, and the like, and a preferable shape is a flat shape from the viewpoint of ink absorbability. The plate-like alumina hydrate has an average aspect ratio of 3 to 8, and preferably an average aspect ratio of 3 to 6. The aspect ratio is expressed as the ratio of the “diameter” to the “thickness” of the particles. Here, the diameter of the particle represents the diameter of a circle equal to the projected area of the particle when the alumina hydrate is observed with an electron microscope. When the aspect ratio is smaller than the above range, sufficient ink absorbability may not be obtained. On the other hand, when the aspect ratio exceeds the above range, it becomes difficult to produce alumina hydrate by aligning the particles.

<評価>
実施例1〜16、参考例1及び2,比較例1〜4で作製したインクジェット記録材料にセイコーエプソン(株)製「MC−10000(プリンタ設定:MC光沢用紙、きれい)」を用いて画像を印刷し、インク受理層表面のひび割れの有無、インク吸収性について評価を行った。評価に用いた画像は黒、シアン、マゼンタ、イエロー、ブルー、レッド、グリーン各色のベタ印字及びその中に白抜き文字を設けたパターン等からなる。
<Evaluation>
Images were prepared using “MC-10000 (printer setting: MC glossy paper, clean)” manufactured by Seiko Epson Corporation on the inkjet recording materials prepared in Examples 1 to 16, Reference Examples 1 and 2 , and Comparative Examples 1 to 4. Were printed and evaluated for the presence or absence of cracks on the surface of the ink receiving layer and ink absorbability. The image used for evaluation is composed of solid prints of black, cyan, magenta, yellow, blue, red, green, and a pattern in which white characters are provided.
インク受理層表面のひび割れの有無は、作製したインクジェット記録材料の表面を目視で観察して評価した。「◎」は全くひび割れが観察されない。「○」は極めて少数の細かいひび割れが観察される。「△」は細かいひび割れが観察されるが実用上問題ない。「×」は大きいひび割れが多数発生して実用不可の状態である。結果を表1の「塗層のひび割れ」に示した。 The presence or absence of cracks on the surface of the ink receiving layer was evaluated by visually observing the surface of the produced inkjet recording material. In “◎”, no cracks are observed. “○” indicates very few fine cracks. In “Δ”, fine cracks are observed, but there is no practical problem. “X” is a state in which many large cracks are generated and impractical. The results are shown in “Crack of coating layer” in Table 1.
インク吸収性は、ベタ印字部分の均一性、隣り合ったベタ印字部の境界部や白抜き文字の鮮鋭性等を目視で観察して評価し、1〜10の数値で表した。1は最もインクの吸収性が悪いことを表し、数値が大きくなるほどインクの吸収性が良好で、10は最もインクの吸収性が良好なことを示す。6以上であれば実用上問題ない。結果を表1の「インク吸収性」に示した。 The ink absorptivity was evaluated by visually observing the uniformity of solid print portions, the boundary between adjacent solid print portions, the sharpness of white characters, and the like, and was represented by a numerical value of 1 to 10. 1 indicates that the ink absorbability is the worst, and the larger the numerical value, the better the ink absorbency, and 10 indicates the most ink absorbability. If it is 6 or more, there is no practical problem. The results are shown in “ink absorbability” in Table 1.
インク発色性は、黒ベタ印字部分の濃度を濃度計(マクベスRD918)を用いて測定した。数値が高い方がインクの発色性が良好で、1.9以上であれば実用上問題なく、1.9よりも低い場合には、印字部分にむらが発生し、実用が不可の状態である。結果を表1の「インク発色性」に示した。 Ink color development was measured by using a densitometer (Macbeth RD918) for the density of the black solid print portion. The higher the numerical value, the better the color developability of the ink. When the value is 1.9 or more, there is no practical problem. When the value is lower than 1.9, unevenness occurs in the printed portion, and the practical use is not possible. . The results are shown in “Ink color development” in Table 1.
表1中、実施例1〜16に示す様に支持体上にアルミナ水和物を主成分とし、少なくともポリビニルアルコール、メタクリル酸エステル−メタクリル酸ジメチルアミノアルキルエステル−スチレン共重合物、ホウ酸またはホウ酸塩、及び硝酸、酢酸、塩酸から選ばれる1種以上の酸を含有するインク受理層の塗液を塗工・乾燥して形成されるインクジェット記録材料により、熱による乾燥を行ってもインク受理層表面にひび割れを生じさせずに顔料インクの吸収性と発色性を兼ね備えたインクジェット記録材料を得ることができた。また、該支持体と該インク受理層の間に顔料層を設けたことで、インク受理層表面にひび割れを生じさせずにインク吸収性の良好なインクジェット記録材料を得ることができた。 In Table 1, as shown in Examples 1 to 16 , alumina hydrate was a main component on the support, and at least polyvinyl alcohol, methacrylate ester-dimethylaminoalkyl ester methacrylate-styrene copolymer, boric acid or An ink-jet recording material formed by applying and drying a coating solution for an ink-receiving layer containing at least one acid selected from borate , nitric acid, acetic acid, and hydrochloric acid. It was possible to obtain an ink jet recording material having both pigment ink absorptivity and color developability without causing cracks on the surface of the receiving layer. Further, by providing a pigment layer between the support and the ink receiving layer, an ink jet recording material having good ink absorbability could be obtained without causing cracks on the surface of the ink receiving layer.
実施例1、16の比較により、該支持体と該インク受理層の間に顔料層を設けることにより、インク受理層表面にひび割れを生じさせずにインク吸収性が良化し、好ましい。 By comparing Examples 1 and 16, it is preferable to provide a pigment layer between the support and the ink receiving layer, since the ink absorption is improved without causing cracks on the surface of the ink receiving layer.
比較例1においては、アルミナ水和物を含有しないため、インクの吸収性及び発色性が低下した。また、比較例2、3及び4においてはインク受理層にホウ酸もしくはポリビニルアルコール、メタクリル酸エステル−メタクリル酸ジメチルアミノアルキルエステル−スチレン共重合物を含有していないため、ひび割れを防止することができなかった。 In Comparative Example 1, since no alumina hydrate was contained, the ink absorptivity and color developability were lowered. In Comparative Examples 2, 3 and 4, since the ink receiving layer does not contain boric acid or polyvinyl alcohol, and a methacrylic acid ester-dimethylaminoalkyl ester methacrylate-styrene copolymer, it is possible to prevent cracking. There wasn't.
