Abstract
Description
本発明は、インクジェット記録方式を利用したインクジェット用記録用媒体に関するものである。特にインク吸収性、高光沢かつ表面強度に優れるインクジェット記録用媒体に関する。 The present invention relates to an inkjet recording medium using an inkjet recording system. In particular, the present invention relates to an ink jet recording medium excellent in ink absorbability, high gloss and surface strength.
インクジェット記録方式は、インクの微小液滴を種々の作動原理により飛翔させて紙等の記録シートに付着させ、画像・文字等の記録を行うものである。該記録方式は、高速、低騒音、多色化が容易、記録パターンの融通性が大きい、現像及び定着が不要等の特徴があり、種々の用途において急速に普及している。更に多色インクジェット方式により形成される画像は、解像度及び色再現範囲の拡大により、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遜色ない記録を得ることが可能であり、作成部数が少なくて済む用途では写真技術によるものよりも安価であることからフルカラー画像記録分野にまで広く応用されつつある。 The ink jet recording method records images, characters, and the like by causing ink droplets to fly on various recording principles and adhere to a recording sheet such as paper. The recording system has features such as high speed, low noise, easy multi-coloring, large flexibility in recording patterns, no need for development and fixing, and is rapidly spreading in various applications. Furthermore, images formed by the multi-color inkjet method can obtain recordings that are comparable to multi-color printing by the plate-making method and printing by the color photographic method by expanding the resolution and color reproduction range. Since it is less expensive than photographic technology, it is widely applied to the field of full-color image recording.
さらに、インクジェット方式を利用したプリンターは、市場からの更なる画像の品質向上に対する要求のために、インクの吸収及び乾燥が速いこと、印字濃度が高いこと、滲みがないこと等があげられる。より高い印字品質を求める場合には媒体上にインクジェットプリンターのインクに対して適性のあるインク受容層を各種基材上に設けた専用の媒体が使用される。これらインクジェット記録専用の媒体としては紙やフィルムを支持体として、無機顔料とバインダーを主成分とする顔料塗工層が表面に設けたものが多く使用される（例えば特許文献１及び２参照）。 Furthermore, in the printer using the ink jet system, due to the demand for further image quality improvement from the market, the ink is absorbed and dried quickly, the print density is high, and there is no bleeding. When a higher print quality is required, a dedicated medium in which an ink receiving layer suitable for the ink of an ink jet printer is provided on various media on the medium is used. As the medium dedicated for ink jet recording, a medium having a pigment coating layer mainly composed of an inorganic pigment and a binder provided on a surface using paper or a film as a support is often used (for example, see Patent Documents 1 and 2).
光沢媒体の製法としては、現在、多量の無機粒子を塗層に含有させて、高光沢を付与している。一般的に無機粒子としてはコロイダルシリカ、アルミナが好ましく使用されている。また、光沢を付与する場合には塗層表面をより平滑にするために、より微細な無機粒子が選択されるようになってきている。 As a method for producing a glossy medium, at present, a large amount of inorganic particles are contained in a coating layer to impart high gloss. In general, colloidal silica and alumina are preferably used as the inorganic particles. In addition, in the case of imparting gloss, finer inorganic particles have been selected in order to make the coating layer surface smoother.
インクの吸収性と光沢を両立させるために、塗工層に微小な無機粒子を多量に含有する光沢層塗工液を塗布した後、塗工層が湿潤状態にあるうちに該塗工層を加熱された鏡面仕上げの金属面に圧着（キャストコート法）して、インクジェット記録用光沢媒体を製造する直接法や塗工層を一度乾燥させた後、温水で該塗工層を再び湿潤状態にさせ、鏡面仕上げの金属面に圧着して、インクジェット記録用光沢媒体を製造するリウェット法が提案されている。 In order to achieve both ink absorptivity and gloss, after applying a gloss layer coating liquid containing a large amount of fine inorganic particles to the coating layer, the coating layer is applied while the coating layer is in a wet state. After pressure-bonding (cast coating method) to a heated mirror-finished metal surface and directly drying the coated layer for inkjet recording glossy media, the coated layer is again wetted with warm water. A rewetting method has been proposed in which a glossy medium for ink-jet recording is produced by pressure bonding to a mirror-finished metal surface.
上記の手法により、インクジェット記録用光沢媒体を得ることができるが、一般的に相反する特性であるインク吸収性と光沢性を両立させることは難しい。詳細に説明すると、無機粒子を多量に使用し、空隙を増すことによって、インク吸収性を向上させた場合、光沢層に使用される無機顔料の分散性が悪く、無機粒子が凝集してしまい、高光沢が得られにくく、また表面強度が低下するという問題がある。また、高光沢を得るために、無機粒子の使用量を減少させた場合、光沢層に使用される無機顔料の分散性は改良され、高光沢性は得られるが、空隙が減少し、インク吸収性が得られにくい。 Although a glossy medium for ink jet recording can be obtained by the above-described method, it is difficult to achieve both ink absorbability and glossiness, which are generally contradictory properties. More specifically, when the ink absorbency is improved by using a large amount of inorganic particles and increasing the voids, the dispersibility of the inorganic pigment used in the glossy layer is poor, and the inorganic particles aggregate, There are problems that high gloss is difficult to obtain and the surface strength is reduced. Also, when the amount of inorganic particles used is reduced to obtain high gloss, the dispersibility of the inorganic pigment used in the gloss layer is improved and high gloss is obtained, but voids are reduced and ink absorption is improved. It is difficult to obtain sex.
以上のことから、現行技術では、光沢層の塗工液の顔料分散性に優れ、インク吸収性、高光沢かつ表面強度に優れるインクジェット記録用光沢媒体を製造することが非常に困難である。現在、このような光沢層の塗工液の顔料分散性を向上させるために、ポリマー分散物を顔料成分として使用することで、改善する報告は見られない。
本発明はこのような状況を鑑み、基材の少なくとも片面に１層以上のインク受容層を設けたインクジェット記録用媒体において、上記従来技術の問題点である光沢層塗工液の顔料分散性に優れ、良好なインク吸収性を保ちながら、高光沢であり、光沢層表面の表面強度にも優れ、印画紙基材あるいはフィルム基材を用いて製造された媒体に匹敵する画質と均一な光沢感を有している記録媒体を提供することを目的とする。 In view of such a situation, the present invention is effective in improving the pigment dispersibility of the glossy layer coating liquid, which is a problem of the above-described prior art, in an inkjet recording medium having at least one ink receiving layer on at least one side of a substrate. Excellent glossiness while maintaining good ink absorbency, excellent surface strength on the glossy layer surface, image quality and uniform glossiness comparable to media produced using photographic paper or film substrates It is an object to provide a recording medium having

The present invention will be described in detail below.
The average particle diameter in the present invention is measured by electron microscope observation as follows.
The polymer dispersion obtained is diluted to 5% by mass with ion-exchanged water, and 5 μl is placed on a metal mesh and dried. Thereafter, 1 μl of ion exchange water is passed through and dried. This operation (sample washing) is performed 10 times. Then, it puts into a vacuum dryer all day and night and makes this a sample.
The maximum diameter of each particle is measured manually for 50 sample fine particles with a transmission electron microscope. In the present invention, the average value of the maximum diameters of these fine particles is referred to as the average particle diameter.
The glass transition temperature can be measured by differential scanning calorimetry (JIS K7121). The midpoint glass transition temperature in this JIS is adopted.
The pigment component of the gloss layer of the present invention contains a polymer dispersion as an essential component. The polymer dispersion is a dispersion having an average particle diameter of 5 to 50 nm obtained by polymerizing an ethylenically unsaturated monomer and the like, and a glass transition temperature of 80 ° C. or more.
本発明におけるポリマー分散物は、（メタ）アクリレート系ポリマー（アクリル酸エステル及び／又はメタクリル酸エステルの重合体又は共重合体）、スチレン−（メタ）アクリレート系ポリマー（スチレンとアクリル酸エステル及び／又はメタクリル酸エステルの共重合体）、ポリスチレン系ポリマー、スチレン−無水マレイン酸系等の共重合体、ＭＢＲ系ポリマー（メチルメタクリレート−ブタジエン共重合体）、ＳＢＲ系ポリマー（スチレン−ブタジエン共重合体）、ウレタン系ポリマー、エポキシ系ポリマー（エポキシ−アクリル系等の変性共重合体）、ＥＶＡ系ポリマー（エチレン−酢酸ビニル共重合体）、メラミン系ポリマー、尿素系ポリマー及びオレフィン系ポリマー、ポリ塩化ビニル系ポリマー、塩素化ポリプロピレン系ポリマー、ポリエチレン系ポリマー、塩化ビニリデン系ポリマー、シリコーン変性アクリル系ポリマー、フッ素−アクリル系ポリマーが含まれる。これらの一種または二種以上を含有することができる。これらの中では、エチレン性不飽和単量体を重合してなるポリマーが好ましく、さらにその中でも（メタ）アクリレート系ポリマー又はスチレン−（メタ）アクリレート系ポリマー、ポリスチレン系ポリマーが特に好ましい。 The polymer dispersion in the present invention includes a (meth) acrylate polymer (acrylic ester and / or methacrylic ester polymer or copolymer), a styrene- (meth) acrylate polymer (styrene and acrylic ester and / or). (Methacrylic acid ester copolymer), polystyrene polymer, styrene-maleic anhydride copolymer, MBR polymer (methyl methacrylate-butadiene copolymer), SBR polymer (styrene-butadiene copolymer), Urethane polymer, epoxy polymer (epoxy-acrylic modified copolymer), EVA polymer (ethylene-vinyl acetate copolymer), melamine polymer, urea polymer, olefin polymer, polyvinyl chloride polymer , Chlorinated polypropylene Mer, polyethylene-based polymers, vinylidene chloride polymers, silicone-modified acrylic-based polymer, a fluorine - include acrylic polymers. One or two or more of these can be contained. In these, the polymer formed by superposing | polymerizing an ethylenically unsaturated monomer is preferable, and also a (meth) acrylate type polymer or a styrene- (meth) acrylate type polymer and a polystyrene type polymer are especially preferable among them.
本発明におけるポリマー分散物の平均粒子径は、５〜５０ｎｍである。前記サイズの粒子は公知の方法で得ることができる、エチレン性不飽和単量体を重合してなるポリマー作製方法の一例として、界面活性剤の存在下で行われる乳化重合が挙げられる。その界面活性剤としては、一般に市販されているアニオン性界面活性剤、ノニオン性界面活性剤、カチオン性界面活性剤及び共重合性乳化剤が使用できる。また、これらの界面活性剤は、単独であるいは二種以上を組み合わせて使用することができる。本発明に使用されるポリマー分散物の界面活性剤量は、特に制限されない。
乳化重合においては、重合開始剤を使用するのが好ましく、過硫酸カリウム、過硫酸アンモニウム等の過硫酸塩、過酸化水素、アゾ系化合物等が使用される。また、これらと還元剤の併用によるレドックス系開始剤を使用することもできる。
乳化重合法としては、一括して仕込み重合する方法、各成分を連続供給しながら重合する方法などが適用できる。重合は通常３０〜８５℃の温度で攪拌下に行われる。
乳化重合により得られるポリマーの平均粒子径は乳化剤の量を増減させることによって制御することができる。水性樹脂エマルジョンの製造方法として、一般的である乳化剤を用いた乳化重合では、生成する水性樹脂エマルジョンの粒子の粒子径は、乳化剤量の増加とともに減少することがよく知られている。平均粒子径が５〜５０ｎｍの微粒子水性樹脂エマルジョンを得るには多量の乳化剤が必要であり、その中でも５ｎｍの方に近づくに従って一層多量の乳化剤が必要になる。その量は乳化剤の可溶化力によっても異なるので一概に規定することは難しく、ある程度試行錯誤を要する。
乳化重合によって得られた水性樹脂エマルジョンはそのままインクジェット記録用媒体に使用することが出来る。
The average particle size of the polymer dispersion in the present invention is 5 to 50 nm. As an example of a method for producing a polymer obtained by polymerizing an ethylenically unsaturated monomer, particles having the above-mentioned size can be obtained by a known method, and emulsion polymerization performed in the presence of a surfactant can be mentioned. As the surfactant, a commercially available anionic surfactant, nonionic surfactant, cationic surfactant and copolymerizable emulsifier can be used. These surfactants can be used alone or in combination of two or more. The amount of the surfactant in the polymer dispersion used in the present invention is not particularly limited.
In the emulsion polymerization, a polymerization initiator is preferably used, and persulfates such as potassium persulfate and ammonium persulfate, hydrogen peroxide, azo compounds and the like are used. Moreover, the redox initiator by using these together with a reducing agent can also be used.
As the emulsion polymerization method, a method of batch polymerization and a method of polymerization while continuously supplying each component can be applied. The polymerization is usually carried out at a temperature of 30 to 85 ° C. with stirring.
The average particle size of the polymer obtained by emulsion polymerization can be controlled by increasing or decreasing the amount of the emulsifier. As a method for producing an aqueous resin emulsion, it is well known that in emulsion polymerization using an emulsifier, which is a general method, the particle diameter of particles of an aqueous resin emulsion to be produced decreases as the amount of the emulsifier increases. In order to obtain a fine particle aqueous resin emulsion having an average particle diameter of 5 to 50 nm, a large amount of emulsifier is required, and among them, a larger amount of emulsifier is required as it approaches 5 nm. Since the amount varies depending on the solubilizing power of the emulsifier, it is difficult to define it unconditionally and requires some trial and error.
The aqueous resin emulsion obtained by emulsion polymerization can be used as it is for an ink jet recording medium.

但し、本発明におけるポリマー分散物のガラス転移温度は、８０℃以上でなければならない。ガラス転移温度が８０℃未満では、塗工層乾燥時にポリマー分散物の粒子が融着し粒子間空隙が不足してインク吸収性が不十分となり、乾燥性や画質が低下するという問題がある。従って、使用するエチレン性不飽和単量体として、好ましくは、メチルメタクリレート、スチレンである。 However, the glass transition temperature of the polymer dispersion in the present invention must be 80 ° C. or higher. When the glass transition temperature is less than 80 ° C., the particles of the polymer dispersion are fused when the coating layer is dried, and there is a problem that the inter-particle voids are insufficient and the ink absorbability is insufficient, resulting in a decrease in drying properties and image quality. Accordingly, methyl methacrylate and styrene are preferable as the ethylenically unsaturated monomer to be used.
本発明におけるポリマー分散物の平均粒子径は、５〜５０ｎｍであり、好ましくは５〜３０ｎｍである。平均粒子径が５ｎｍ未満では、粒子間空隙が不足してインク吸収性が不十分となり、乾燥性や画質が低下するという問題がある。また平均粒子径が５０ｎｍを超える場合には、光沢性に問題があり、使用できない。
本発明におけるポリマー分散物の粒子形状は真球でも構わないが、異形形状、特に粒子表面に一つ以上の突起がある粒子を使用することで、よりインクの吸収性を増大させることができる。表面に突起がある粒子は、真球の粒子と比較して、粒子間空隙が増大するため、インクの吸収性が増大する。
The average particle size of the polymer dispersion in the present invention is 5 to 50 nm, preferably 5 to 30 nm. When the average particle diameter is less than 5 nm, there is a problem that the interparticle voids are insufficient, the ink absorbability is insufficient, and the drying property and the image quality are deteriorated. On the other hand, when the average particle diameter exceeds 50 nm, there is a problem with glossiness and it cannot be used.
The particle shape of the polymer dispersion in the present invention may be a true sphere, but the ink absorbability can be further increased by using irregularly shaped particles, particularly particles having one or more protrusions on the particle surface. Particles with protrusions on the surface have increased interparticle voids compared to true spherical particles, and thus increase the ink absorbability.
表面に一つ以上の突起のある粒子の作製方法の一例として、はじめに球状の高分子微粒子を作製し、その中に異種のモノマーを膨潤させ、高分子微粒子内でフリーラジカル重合を行うことを特徴とする、もしくは、球状の高分子微粒子に多官能性モノマーを共重合することで、粒子表面近くに、モノマーを膨潤させ、水溶性開始剤でフリーラジカル重合を行うことを特徴とする、シード重合法と称される方法を用いれば、表面に一つ以上の突起がある高分子微粒子が合成できることが知られている（大久保 政芳 高分子５０巻９月号６９６頁２００３年）。 As an example of a method for producing particles having one or more protrusions on the surface, first, spherical polymer fine particles are produced, and different types of monomers are swollen therein, and free radical polymerization is performed in the polymer fine particles. Or by polymerizing a polyfunctional monomer into spherical polymer fine particles to swell the monomer near the particle surface and to carry out free radical polymerization with a water-soluble initiator. It is known that polymer fine particles having one or more protrusions on the surface can be synthesized by using a method called legal (Masayoshi Okubo, Vol. 50, September, p. 696, 2003).
表面に一つ以上の突起がある高分子微粒子の形状として、だるま状、金平糖状、いいだこ状、ラズベリー状を挙げることができる。
本発明におけるポリマー分散物は、粒子形状が真球であるものと、表面に一つ以上のある突起がある粒子をそれぞれ単独使用することができる。また、両者を混合して使用することもできる。
Examples of the shape of the polymer fine particle having one or more protrusions on the surface include a daruma shape, a confetti shape, an octopus shape, and a raspberry shape.
As the polymer dispersion in the present invention, particles having a true sphere shape and particles having one or more protrusions on the surface can be used alone. Moreover, both can be mixed and used.

更に、光沢層には、添加剤として、離型剤、分散剤、増粘剤、防腐剤、消泡剤、着色染料、着色顔料、蛍光増白剤、耐水化剤、レベリング剤、酸化防止剤、紫外線吸収剤等の添加剤を適宜選定して添加することができる。
The amount of adhesive used is determined in consideration of the printability of the recording medium, the strength of the glossy layer, and the coating liquid property. Usually, it is preferable to add in the range of 5-50 mass parts with respect to 100 mass parts of pigment components. If it is less than 5 parts by mass, the strength of the coating layer is inferior, and if it exceeds 50 parts by mass, the ink absorbency is adversely affected.

Coating amount is 2 to 40 g / m 2 in terms of solid content, preferably in the range of 3 to 20 g / m 2. When the coating amount exceeds 40 g / m 2 , the productivity is inferior, and when the coating amount is less than 2 g / m 2 , it is difficult to form a sufficiently glossy surface.
本発明のポリマー分散物と接着剤が含有する層は、実質的に無機粒子を含有していなくてもインク吸収性に優れるため、必ずしも無機粒子を含有させる必要はないが、無機粒子を含有させることも可能である。その量はポリマー分散物１００質量部に対し５０質量部以下が好ましい。無機粒子としては、具体的には、例えば、軽質炭酸カルシウム、重質炭酸カルシウム、炭酸マグネシウム、カオリン、クレー、タルク、硫酸カルシウム、硫酸バリウム、二酸化チタン、酸化亜鉛、水酸化亜鉛、硫化亜鉛、炭酸亜鉛、ハイドロタルサイト、珪酸アルミニウム、ケイソウ土、珪酸カルシウム、珪酸マグネシウム、合成非晶質シリカ、コロイダルシリカ、アルミナ、コロイダルアルミナ、擬ベーマイト、水酸化アルミニウム、リトボン、ゼオライト、水酸化マグネシウム等が挙げられる。高い空隙率を得てインク吸収性を向上させるためには、シリカやアルミナが好ましく、特に５〜５０ｎｍの微粒子である。 The layer containing the polymer dispersion and the adhesive of the present invention is excellent in ink absorbency even if it does not substantially contain inorganic particles.

本発明のインクジェット記録媒体において、支持体の少なくとも片面に形成するインク受容層は、公知のものを使用できる。かかるインク受容層を構成する成分としては、主要成分としてコロイダルシリカや合成シリカ等の無機顔料、ポリビニルアルコール等の接着剤、インク定着剤等が挙げられ、また添加剤成分として分散剤、消泡剤、帯電防止剤、紫外線吸収剤等が挙げられる。インク受容層を構成する主要成分の割合は通常、無機顔料５〜９７質量％、接着剤３〜９５質量％、インク定着剤０〜２５質量％とし、またその塗工量は通常、支持体上に０．５〜３０ｇ／ｍ2の割合である。 In the ink jet recording medium of the present invention, a known ink receiving layer formed on at least one surface of the support can be used. Examples of components constituting the ink receiving layer include inorganic pigments such as colloidal silica and synthetic silica as main components, adhesives such as polyvinyl alcohol, ink fixing agents, and the like, and dispersants and antifoaming agents as additive components. , Antistatic agents, ultraviolet absorbers and the like. The proportion of the main component constituting the ink receiving layer is usually 5 to 97% by weight of an inorganic pigment, 3 to 95% by weight of an adhesive, and 0 to 25% by weight of an ink fixing agent. The coating amount is usually on the support. The ratio is 0.5 to 30 g / m 2 .

光沢を付与する場合には、その処理方法についても特に限定はなく、例えば一般的なカレンダー処理法、つまりはスーパーカレンダー、グロスカレンダー等のカレンダー装置を用い、圧力や温度をかけたロール間を通過させて塗層表面を平滑化する従来既知の方法を用いることができる。
また、一般的に印刷用キャストコート紙の製造で行われている、直接法、凝固法、リウエット法、プレキャスト法などのキャストコーティング法も好ましく用いることができる。キャストコーティング法とは支持体上の塗層を湿潤状態におき、加熱した鏡面ロールに該層を圧接して、該ロールの鏡面を該層に転写して光沢を得る方法であり、該層は該ロールと接している間に乾燥される。
When gloss is imparted, there is no particular limitation on the processing method. For example, a general calendar processing method, that is, a calendar device such as a super calendar or a gloss calendar is used to pass between rolls subjected to pressure or temperature. Thus, a conventionally known method for smoothing the surface of the coating layer can be used.
In addition, cast coating methods such as a direct method, a coagulation method, a rewetting method, and a precast method that are generally performed in the production of cast coated paper for printing can also be preferably used. The cast coating method is a method in which a coating layer on a support is placed in a wet state, the layer is pressed against a heated mirror roll, the mirror surface of the roll is transferred to the layer, and gloss is obtained. It is dried while in contact with the roll.
カレンダー処理法やキャストコーティング法に係る圧接時の圧力、鏡面ロールの温度、塗工速度等は適宜選択される。特に鏡面ロールの温度は、ポリマー分散物の粒子が完全に融着しない程度の温度であることが好ましい。鏡面ロールの温度がその温度よりも高いと、粒子が融着し粒子間空隙が不足してインク吸収性が不十分となり、乾燥性や画質が低下するという問題がある。 The pressure at the time of pressure welding according to the calendar treatment method or the cast coating method, the temperature of the mirror roll, the coating speed, etc. are appropriately selected. In particular, the temperature of the mirror surface roll is preferably such that the particles of the polymer dispersion are not completely fused. If the temperature of the mirror roll is higher than that temperature, there is a problem that the particles are fused and the inter-particle voids are insufficient, resulting in insufficient ink absorbability, resulting in reduced drying properties and image quality.
