Description

明 細書 ブロックポリマーを含有する組成物 技術分野  Description A composition containing a block polymer Technical Field
本発明は、 印刷ィンク等に適用可能な組成物に関する。 背景技術  The present invention relates to a composition applicable to printing ink and the like. Background art
近年、非常な勢いでデジタル印刷技術は進歩している。その中でも水溶性 の染料インクを用いた印刷方法は、高画質印刷が可能となっている。 しかし ながら、仮に被記録媒体上で乾燥した染料であっても、染料インクは、紙上 に印字した場合、色の重ね合わせ時ににじみを生じたり、吐出直後に毛細管 現象によりインクが被記録媒体上の繊維方向に染み出す現象 (フエザリン グ) が観測される等、 印字物の保存性に大きな問題があった。  In recent years, digital printing technology has progressed with great speed. Among them, printing methods using water-soluble dye inks enable high-quality printing. However, even if the dye is dried on the recording medium, the dye ink, when printed on paper, causes blurring when the colors are superimposed, or the ink on the recording medium due to capillary action immediately after ejection. There was a big problem in the storability of the printed matter, such as the phenomenon of feathering (feathering) observed.
これらの問題を解決する手段として、染料分散体に代え顔料分散体、特に 顔料を水溶性樹脂で分散させた顔料分散体を用レ、ることが提案されている As a means for solving these problems, it has been proposed to use a pigment dispersion, particularly a pigment dispersion in which a pigment is dispersed with a water-soluble resin, instead of a dye dispersion.
(米国特許第 5 , 0 8 5, 6 9 8号公報参照)。 顔料は印字後も粒子状で存 在するため、例えば紙上に印字する場合、にじみやフエザリングが軽減され、 保存性に優れた色材として利用することができるものの、我々の鋭意検討の 結果、普通紙と呼ばれるポアサイズが比較的大きなメディアを用いた印刷に おいては顔料粒子であったとしても、顔料粒子がメディァ上に十分に残存で きず十分な発色性が得られな!/、場合があった。このような問題を解決する手 段としては単純に顔料濃度を上昇させる事や、前記水溶性樹脂の親水性を低 下させる事(特開 2 0 0 0— 2 7 3 3 7 3公報参照)や前記水溶性樹脂量を 低下させる試み(特開 2 0 0 0— 2 9 0 5 5 4公報参照)が行なわれている。 しかしながら我々の鋭意検討の結果、単純に顔料濃度を上げることは同'時に 濃度を上昇させることであるためインク吐出等に問題を生じる場合がある ことから組成物として不適切な場合がある。また、前記水溶性樹脂の水溶性 を低下させることや、前記水溶性樹脂自身を低下させることで、普通紙上で の発色性は得られるものの、コート原紙の上に力オリン等を塗布した被記録 媒体、いわゆるコート紙へ印刷を行なった場合に、印刷画像上の問題を生じ ることがあった。すなわち、前記顔'料分散体を用いた印刷画像は、印字後も 顔料がメディァの内面に浸透しにくく、コート紙上に顔料が積層した形とな り十分な堅牢性が得られず、爪による引つ搔きや、紙、布等の物理的な外力 に対し不十分な場合があった。 (See US Pat. No. 5,085,698). Since pigments remain in particulate form after printing, for example, when printing on paper, bleeding and feathering are reduced, and they can be used as coloring materials with excellent storage stability. In printing using media with a relatively large pore size called paper, even if the particles are pigment particles, the pigment particles do not remain sufficiently on the media and sufficient color developability cannot be obtained! / It was. As a means for solving such a problem, simply increasing the pigment concentration or decreasing the hydrophilicity of the water-soluble resin (refer to Japanese Patent Laid-Open No. 2 0 00-2 7 3 3 7 3). In addition, attempts have been made to reduce the amount of the water-soluble resin (see Japanese Patent Application Laid-Open No. 2000-290-54). However, as a result of our diligent studies, it is not possible to simply increase the pigment concentration Since increasing the concentration may cause problems in ink ejection and the like, it may be inappropriate as a composition. In addition, although the coloring property on plain paper can be obtained by lowering the water solubility of the water-soluble resin or by reducing the water-soluble resin itself, the recording is carried out by applying force orin etc. on the coated base paper. When printing on a medium, so-called coated paper, there may be a problem with the printed image. That is, a printed image using the above-mentioned facial material dispersion does not easily penetrate the inner surface of the media even after printing, and the pigment is laminated on the coated paper, so that sufficient fastness cannot be obtained and In some cases, it was insufficient for pulling and physical external forces such as paper and cloth.
従って、現在まで発色性が向上し十分な堅牢性が得られ、またこれら効果 が被記録媒体に依存する事のない組成物を得ることは困難であった。 発明の開示  Therefore, until now, it has been difficult to obtain a composition in which the color developability is improved and sufficient fastness is obtained, and these effects do not depend on the recording medium. Disclosure of the invention
本発明は、上記事情に鑑みてなされたものであり、にじみやフエザリン グが軽減され、印刷画像の保存といった顔料ィンクに特徴的な効果だけでは なく、発色性が向上し十分な堅牢性が得られ、またこれら効果が被記録媒体 に依存する事のない組成物を提供するものである。 .  The present invention has been made in view of the above-described circumstances, and it is possible to reduce bleeding and feathering, and not only have a characteristic effect on pigment linking such as storage of printed images, but also improve color development and provide sufficient fastness. In addition, the present invention provides a composition in which these effects do not depend on the recording medium. .

Next, a riving polymerization method of a block polymer containing a polyalkenyl ether structure produced preferably in the present invention will be described. A number of methods for synthesizing polymers containing a polyvinyl ether structure have been reported (for example, published in JP-A-11-080221), but the method by Aoshima et al. (Polymer Builetin, 15, 41 7-423 (1986)). JP-A-11-322942 and JP-A-11-322866) are representative. By synthesizing high molecular compounds by the method of Aoshima et al., Length (molecular weight) of various polymers such as homopolymers, copolymers composed of two or more monomers, block polymers, and draft polymers can be obtained. It can be accurately aligned and synthesized.
また本発明の組成中に含有される前記一般式で表される繰り返し単位構 造を有するプロックポリマーは、本発明の組成物の重量に対して、 0. 5〜 98質量%が好ましく、 本発明に使用するブロックポリマーの平均分子量 (Mn) として好ましくは 1,000〜1,000,000の範囲、 粘度等を考慮すると より好ましくは 3,000〜500,.000の範囲である。  Further, the block polymer having a repeating unit structure represented by the above general formula contained in the composition of the present invention is preferably 0.5 to 98% by mass with respect to the weight of the composition of the present invention. The average molecular weight (Mn) of the block polymer used in is preferably in the range of 1,000 to 1,000,000, and more preferably in the range of 3,000 to 500,000 when considering the viscosity.
なお、'一般に、 ポリマーの膜としての機械強度を向上させようとすれば、 分子量の大きなポリマーを用いポリマー同士の絡み合いを大きくする方法 が考えられるが、同時に溶液が高粘度になることが予測され、微小量単位で 画像を形成する場合、 取り扱いが困難になる。 - そこで、本発明のように、ァミノ基と一般的なメディアの主成分であるセ ルロースに付与した水酸基の水素結合を利用して、機械強度を向上させる方 法は、低分子量のポリマーであっても十分な機械強度を発現することが期待 でき、かつ低粘度化が実現できるため、インク組成物の物性を設計する際に 非常に有益となる。 In general, to improve the mechanical strength of a polymer film, a method of increasing the entanglement between polymers using a polymer having a high molecular weight can be considered, but at the same time, it is predicted that the solution will have a high viscosity. When an image is formed in minute units, handling becomes difficult. -Therefore, as in the present invention, a method for improving the mechanical strength by utilizing the hydrogen bond between an amino group and a hydroxyl group imparted to cellulose, which is a main component of general media, is a low molecular weight polymer. However, when designing the physical properties of the ink composition, sufficient mechanical strength can be expected and low viscosity can be realized. It will be very useful.

上記の熱エネルギーを発生する手段を備えた装置の代表的な構成や原理 については、例えば、米国特許第 4 7 2 3 1 2 9号明細書, 同第 4 7 4 0 7 9 6号明細書に開示されている基本的な原理を用いて行うものが好ましレ、。 この方式は所謂オンデマンド型,コンティニユアス型のレ、ずれにも適用可能 であるが、 特に、 オンデマンド型の場合には、液体が保持され、流路に対応 して配置されている電気熱変換体に、吐出情報に対応していて核沸縢を越え' る急速な温度上昇を与える少なくとも 1つの駆動信号を印加することによ つて、電気熱変換体に熱エネルギーを発生せしめ、へッドの熱作用面に膜沸 縢を生じさせて、結果的にこの駆動信号に一対一で対応した液体内の気泡を 形成できるので有効である。この気泡の成長および収縮により吐出用開口を 介して液体を吐出させて、少なくとも 1つの滴を形成する。 この駆動信号を パルス形状とすると、即時適切に気泡の成長収縮が行われるので、特に応答 性に優れた液体の吐出が達成でき、より好ましレ、。 このパルス形状の駆動信 号としては、米国特許第 4 4 6 3 3 5 9号明細書, 同第 4 3 4 5 2 6 2号明 細書に記載されているようなものが適している。なお、上記熱作用面の温度 上昇率に関する発明の米国特許第 4 3 1 3 1 2 4号明細書に記載されてい る条件を採用すると、 さらに優れた吐出を行うことができる。  For a typical configuration and principle of a device provided with the above-described means for generating thermal energy, see, for example, US Pat.

In particular, in the case of the on-demand type, the liquid is held and the electric power arranged corresponding to the flow path is used. By applying at least one drive signal corresponding to the discharge information and giving a rapid temperature rise exceeding the nucleate boiling point to the heat converter, heat energy is generated in the electrothermal converter. This is effective because film boiling occurs on the heat acting surface of the lid, and as a result, bubbles in the liquid corresponding one-to-one with the drive signal can be formed. By the growth and contraction of the bubbles, the liquid is ejected through the ejection opening to form at least one droplet. If this drive signal is pulse-shaped, the bubble growth and contraction is performed immediately and appropriately, so that it is possible to achieve liquid discharge with particularly excellent responsiveness.

また、 引搔き球 0. 5 mmと.してァクリル球、 荷重 500 g、 引っ張り速 度 10mm/秒の条件で堅牢性試験を行った。 ところ実施例においては; 引 つ接きに対して、光沢紙部分である白地がほとんど発生しなかつたのに対し、 比較例 3、 4は実施例と比較して、 光沢紙部分である白地が多く見られた。 従って、本発明のポリマーはいずれもィンクジェットでの印字が可能であ つた。.また、上記普通紙の評価で高い光学濃度を示した本発明のィンク組成 物はコート紙における耐擦過性でも優れていることがわかった。 これは、 コ 一ト紙上でァミンの水素結合がィンク層の膜の形成に働いたためと考えら 'れる。一方、普通紙での光学濃度を上げるために単純にインク中のポリマー 量を減らした比較例では、 画像の堅牢性が著しく悪くなつている。 In addition, a robustness test was conducted under the conditions of an acryl ball, a load of 500 g, and a pulling speed of 10 mm / sec. However, in the examples: The white background, which is a glossy paper portion, hardly occurred when touched, whereas in Comparative Examples 3 and 4, a lot of white background, which was a glossy paper portion, was seen compared to the Examples. Therefore, any of the polymers of the present invention can be printed with an ink jet. Further, it was found that the ink composition of the present invention, which showed a high optical density in the evaluation of the above plain paper, was excellent in scratch resistance on the coated paper. This is thought to be due to the fact that the amine hydrogen bond worked on the film on the coated paper. On the other hand, in the comparative example in which the amount of polymer in the ink is simply reduced in order to increase the optical density on plain paper, the fastness of the image is remarkably deteriorated.
以上の評価から、本発明のインク組成物は、 コート紙上の耐擦過性を保て るだけのポリマーを含んでいても、普通紙上で高 、光学濃度が実現可能なこ とを明ら力にした。  From the above evaluations, the ink composition of the present invention clearly shows that even if it contains a polymer that can keep the scratch resistance on the coated paper, high optical density can be realized on plain paper. .
少なくとも本発明のィンク組成物においては、被記録媒体上で高い発色性 と堅牢性を同時に示す画像を形成することができるので、記録物の堅牢性向 上の為に好適なプロックポリマー、 インク組成物を提供することができる。 また、本発明によると、光沢紙や普通紙といった被記録媒体に比較的依存せ ずに効果を発現することができる。  Since at least the ink composition of the present invention can form an image showing both high color development and fastness on the recording medium, it is a suitable block polymer or ink composition for improving the fastness of the recorded matter. Can be provided. In addition, according to the present invention, the effect can be exhibited relatively independently of a recording medium such as glossy paper or plain paper.
