Description

【0001】
【産業上の利用分野】
本発明は熱溶融型熱転写プリンターに適した、ドット再現性に優れかつ印字部と非印字部の光沢差の発生を限りなく抑制した熱転写記録用紙に関する。
【0002】
【従来の技術】
近年、シアン、マゼンタ、イエロー、ブラックのインク層を塗工したフィルム(インクリボン)と紙(受像紙)とを合わせてサーマルヘッドに通し、そこで熱を与えてインクを紙に加熱溶融転写させる溶融型熱転写プリンターが普及してきている。
【0003】
このシステムにおける受像紙としてはスーパーカレンダー等で表面処理した平滑度の高い紙が熱転写用紙として使用されている。特にその記録面の平滑度が100秒以上で転写画像の鮮明度が改善されることが従来より知られている。平滑度が高いことはインクリボンとの密着性が高まるため、インク転写性は良くなる。しかし、近年ではより高精細、高画質化の要求が高まっており、その意味において、上記熱転写用紙は、ハーフトーンでの印刷濃度階調再現性、高濃度領域における印刷濃度階調再現性、低濃度領域におけるドット抜け(再現性)の発生により高解像度、高精細な印刷特性が得られていないのが現状であった。
【0004】
一方、光沢度の高い塗工紙として、アート紙やキャストコート紙は、塗工層表面の凹凸及び空隙が少ないため、溶融したインクを十分に受容できず転写不良が顕著に起こるため熱転写用紙としては不向きであった。そこで、特定の比表面積を有する合成シリカを一定以上含有せしめ、キャストコートすることで光沢度が高くインク転写性を改善する方法が提案されている(特開平5―131766)。
【0005】
しかしながら、合成シリカなどの比表面積の高い顔料をコート層に含有することは、塗工層表面の凹凸及び空隙の増大により転写特性を改善するが、転写が必要以上に良すぎる場合にはサーマルヘッドが加熱されていない状態でもインクが紙に薄く転写される現象(リボン汚れ)が発生すること、サーマルヘッドに対する摩耗性が悪くプリンターを傷めやすいこと、一般のキャストコート紙等に比べ光沢が低くなることなどの問題があるだけでなく、インク転写性が改善されていながらも低濃度領域でのドット抜け(再現性)、ハーフトーンの再現性、高濃度領域における印刷濃度階調再現性は不十分であった。
【0006】
また、マイクロカプセル状の中空ポリマー粒子を中間層に用いることで断熱性の向上により、転写性を改善する提案もなされている(特開平11−321128)。しかしながら、溶融型熱転写においてはインクと接触する最表面の影響が大きく、従って、一般のオフセット印刷や銀塩写真に匹敵するような高精細、高画質な画像を得ることができなかった。
【0007】
そこで、熱溶融型熱転写においては、最表面において断熱層を設けることで転写感度が向上すると予想されるが、中空ポリマー粒子が最表面に存在することで光沢度が必要以上に高くかつクッション性が向上しすぎるために印字後(サーマルヘッド通過後)の印字部と非印字部の光沢差が顕著になってしまい、印字後の外観が損なわれてしまうと考えられる。
【0008】
以上の理由から、最表面に断熱性を有し、かつ印字後の光沢差が発生しないような記録層を形成させる必要があった。
【0009】
【発明が解決しようとする課題】
本発明者は、溶融型の熱転写記録において、インクの転写性が良好であり、低濃度から高濃度まで全ての領域においてドット抜けがなく、ドット再現性が良好であり印刷濃度階調再現性に優れており、鮮明な高解像度の画像をカラープリンター等で得られ、かつ印字後の印字部と非印字部の光沢差を限りなく抑制できる熱転写用紙を提供することを目的とする。
【0010】
本発明者は、上記課題を解決すべき鋭意検討を行った結果、持体上に少なくとも1層以上の塗工層を設けた熱転写記録用紙において、塗工層の最表層が記録層であり、記録層がカオリン、焼成カオリン、珪酸アルミニウム、軽質炭酸カルシウムのいずれか一つから選択されてなる30〜80重量%の無機顔料と20〜70重量%のおわん型有機顔料とよりなる顔料100重量部およびスチレン−ブタジエン共重合ラテックスと澱粉との組み合わせ又はポリウレタン樹脂と澱粉との組み合わせであるバインダー20〜100重量部を含有し、かつ、前記記録層のJIS 8142法による75度鏡面白紙光沢度が54%以下であることを特徴とする熱転写記録用紙によって上記課題が解決されることをみいだした
【0011】
本発明の熱転写記録用紙の一つの実施態様は、おわん型有機顔料が平均粒子径0.1〜10μmであるものである。
【0013】
更に別の本発明の実施態様は、前記記録層のJIS P 8119法によるベック平滑度が500秒以上であるものである。
【0014】
また、無機顔料の内、JIS K 5101法による吸油度40ml/100g以上の無機顔料が顔料全体の10〜90重量%である上記熱転写記録用紙も本発明の実施態様である。
【0015】
本発明に用いる顔料としては、おわん型有機顔料を含有する事が好ましい。ここでおわん型有機顔料とは、顕微鏡下でおわん型を有しており白色を呈するポリマー粒子を言う。この粒子の平均粒子径は0.1から10μm以下のものが好ましい。おわん型有機顔料の組成は特に限定されるものではないが、スチレン、エチレン、塩化ビニル、アクリルおよび酢酸ビニルのポリマーまたはこれらモノマー相互のコポリマー、ポリウレタン、ポリカーボネート、ナイロンなどのポリマー微粒子およびこれらの共重合体などが挙げられる。耐熱性等の観点からスチレンーアクリル共重合体が好適に用いられる。平均粒子径は0.1μm未満では有機顔料としての特性である十分な断熱性が得られず、10μmを越えると記録層の凹凸が大きくなるためインクの転写が悪くなり好ましくない。また、2 種以上の異なる粒子径のものを併用することも可能である。おわん型有機顔料を使用することで、記録層のクッション性が向上する事によるサーマルヘッドと記録面との密着性及び断熱性が向上しサーマルヘッドの熱エネルギーが無駄なく伝達されるため発色感度向上の効果が得られる。また、無機粒子に比べて有機顔料は顔料自体が柔らかいためにヘッド摩耗がほとんど発生せず、かつ、おわん型有機顔料は非球状であるためにサーマルヘッド通過後の記録層のへこみが最小限に抑えられ、結果的に光沢度の低下を防げることで、印字部と非印字部の光沢差を限りなく抑制することができる。本発明においては、おわん型有機顔料の配合量は顔料全体の10〜70重量%が好適である。10重量%未満では記録層の断熱性及びクッション性が低下し、70重量%を超えると印字部と非印字部の光沢差が大きくなり、印字後の外観が損なわれる。
【0016】
また、本発明に用いる無機顔料は特に限定されないが、JIS K 5101法による吸油度が40ml/100g以上の無機顔料は多孔性の為溶融したインクを吸収することで、インク転写性及びインク定着性が向上する為好ましい無機顔料である。このような無機顔料としては、焼成カオリン、水酸化マグネシウム、炭酸マグネシウム、珪酸アルミニウム、合成シリカ、水酸化アルミニウム、ケイソウ土等が挙げられる。その他組み合わせる無機顔料としては、炭酸カルシウム、クレー、タルク、カオリン、硫酸バリウム、二酸化チタン、亜鉛等が上げられるが特に限定されるものではない。本発明においては、無機顔料の配合量は顔料全体の30〜90重量%が好適である。30重量%未満では印字部と非印字部との光沢差が大きくなり、90重量%を超えるとリボン汚れが発生しやすい、ヘッド摩耗が大きいなどの問題がある。
【0017】
本発明に用いられるバインダーとしては、顔料及び原紙との接着力が強く、用紙間でまたは用紙とインクリボンとの間でブロッキングを起こさない樹脂を適宜使用することが好ましく、エマルジョン、ラテックス、天然高分子等を使用できる。このようなバインダーとしては、スチレンーブタジエン共重合体、変性スチレンーブタジエン共重合体、アクリロニトリルーブタジエン共重合体、メチルメタアクリレートーブタジエン共重合体、クロロプレンラテックス、アクリル酸エステル及びメタアクリル酸エステルの重合体又は共重合体、エチレン酢酸ビニル共重合体、酢酸ビニルーマレイン酸エステル共重合体、アクリルー酢酸ビニル共重合体、酢酸ビニル共重合体、でんぷん、酸化でんぷん、エステル化でんぷん、酵素変性でんぷん、カチオン化でんぷん、ポリビニルアルコール、ヒドロキシエチルセルロース、カルボキシメチルセルロース等のセルロース誘導体、ポリアクリルアミド類、ポリビニルピリジン、ポリエチレンオキサイド、ポリビニルピロリドン、カゼイン、アルギン酸ソーダ、ポリスチレンスルホン酸ソーダ、でんぷんーアクリロニトリルグラフトポリマー加水分解物、スルホン化キチン、カルボキシル化キチン及びキトサンとそれらの誘導体等を例示することができる。
【0018】
塗工液組成中のバインダーの添加量は、特に限定されるものではないが、顔料100重量部に対して10〜100重量部であることが好ましい。バインダーが顔料100重量部に対して10重量部より少ないと塗工層の強度が弱く、塗工層の脱落、粉落ちなどの問題が発生するため好ましくない。また、100重量部を越えると塗工性の悪化やコスト高になるため好ましくない。
【0019】
塗工液には、必要に応じて分散剤、消泡剤、離型剤、PH調整剤、潤滑剤、保水剤、増粘剤、界面活性剤、蛍光増白剤、着色顔料、着色染料、流動改良剤などを適宜選定して添加することができる。
【0020】
このようにして調整された塗工液を公知の塗工方法によって塗工層を設けることで、本発明の熱転写用記録紙を得ることができる。
塗工量は片面あたりの乾燥塗工量が5〜50g/m2、好ましくは7〜35g/m2となるようにオンマシンあるいはオフマシンコーターで単層あるいは多層塗工される。塗工量が5g/m2より少ない場合には、紙表面の被覆が不十分であるため均一な表面性を得ることが困難である。また、塗工量が50g/m2を越える場合はコスト高になってしまうため好ましくない。
【0021】
記録層を得るための塗工方式は特に限定されるものではなく、一般の塗工方式、例えば、ブレードコーター、ロールコーター、リバースロールコーター、エアーナイフコーター、ダイコーター、バーコーター、グラビアコーター、カーテンコーター、チャンブレックスコーター、リップコーター、ロッドコーターなどの塗工方式を採用することができる。
【0022】
本発明においては、記録層のJIS P 8142法による75度鏡面白紙光沢度が70%以下であることが好ましい。白紙光沢度を必要以上に上げることを防ぐことにより、印字部と非印字部の光沢度差を極力抑制することが可能である。白紙光沢度が70%を超える場合においては、サーマルヘッド通過後に白紙光沢度が低下しやすく、印字部と非印字部の光沢度差が発生しやすい。
【0023】
また、記録層のJIS P 8119法によるベック平滑度が500秒以上であることが好ましい。記録層のベック平滑度が500秒以下の場合においては、塗工層表面の凹凸の増大によりインクの転写性が悪化していく傾向にある。
本発明においては、特に中間層を必要としなくても良好な熱転写特性を有するものであるが、中間層を設けても何ら差し支えなく、最表層である記録層が上記のごとく形成されていれば良い。
【0024】
支持体としては、酸性及び中性の上質紙や中質紙等が使用できるが、塗工原紙としての塗工適性を備えた支持体を使用することが好ましい。
なお、本発明の熱転写記録用紙は、外観や平滑性向上の目的で記録層を塗布後スーパーカレンダーやソフトカレンダーなど公知の加圧装置にて平滑化処理を行うことが出来る。また、必要に応じて裏面に帯電防止処理、滑り性を付与する為の処理、タック加工などを施すことも出来る。
【0025】
【発明の効果】
以上詳述したごとく、本発明の熱転写用記録紙は、インクの転写性が良好であり、サーマルヘッドに与える熱エネルギーが低濃度から高濃度まで全ての領域においてドット抜けがなく、ドット再現性が良好であり印刷濃度階調再現性に優れているとともに、リボン汚れが無く、ヘッド摩耗性が良好であり、鮮明な高解像度の画像を得ることができ、更に印字部と非印字部の光沢差の発生を限りなく抑制することが可能であり、特に溶融型熱転写プリンターの熱転写用記録紙として好適である。

[Industrial application fields]
The present invention relates to a thermal transfer recording paper that is suitable for a hot melt type thermal transfer printer and has excellent dot reproducibility and suppresses the occurrence of a gloss difference between a printed portion and a non-printed portion.
[0002]
[Prior art]
In recent years, a film (ink ribbon) coated with an ink layer of cyan, magenta, yellow, and black and paper (image receiving paper) are combined and passed through a thermal head, where heat is applied to melt the ink to heat, melt and transfer to paper. Mold thermal transfer printers are becoming popular.
[0003]
As the image receiving paper in this system, high smoothness paper surface-treated with a super calender or the like is used as thermal transfer paper. In particular, it has been conventionally known that the sharpness of the transferred image is improved when the smoothness of the recording surface is 100 seconds or more. High smoothness increases the adhesion to the ink ribbon, so that the ink transferability is improved. However, in recent years, there has been an increasing demand for higher definition and higher image quality. In this sense, the thermal transfer paper has a halftone print density gradation reproducibility, a high print density gradation reproducibility in a high density region, a low density. The current situation is that high-resolution and high-definition printing characteristics cannot be obtained due to the occurrence of missing dots (reproducibility) in the density region.
[0004]
On the other hand, art paper and cast coated paper, as coated paper with high gloss, have few irregularities and voids on the surface of the coating layer, so that the melted ink cannot be sufficiently received and transfer defects occur remarkably. Was unsuitable. In view of this, a method has been proposed in which synthetic silica having a specific specific surface area is contained in a certain amount or more and cast coating to improve the ink transfer property with high glossiness (Japanese Patent Laid-Open No. 5-131766).
[0005]
However, containing a pigment having a high specific surface area such as synthetic silica in the coating layer improves the transfer characteristics by increasing the irregularities and voids on the surface of the coating layer, but if the transfer is more than necessary, the thermal head Even when the paper is not heated, the phenomenon that ink is thinly transferred to the paper (ribbon stains) occurs, the thermal head is not easily worn and the printer is easily damaged, and the gloss is lower than that of general cast-coated paper. In addition to improved ink transferability, dot missing (reproducibility) in low density areas, halftone reproducibility, and print density gradation reproducibility in high density areas are insufficient. Met.
[0006]
In addition, a proposal has been made to improve transferability by using microcapsule-shaped hollow polymer particles in an intermediate layer to improve heat insulation (Japanese Patent Laid-Open No. 11-321128). However, in the melt type thermal transfer, the influence of the outermost surface in contact with the ink is large, and therefore a high-definition and high-quality image comparable to general offset printing and silver salt photography could not be obtained.
[0007]
Therefore, in heat melting type thermal transfer, it is expected that the transfer sensitivity is improved by providing a heat insulating layer on the outermost surface, but the presence of hollow polymer particles on the outermost surface increases the glossiness more than necessary and provides cushioning properties. It is considered that the gloss difference between the printed part after printing (after passing the thermal head) and the non-printed part becomes remarkable due to excessive improvement, and the appearance after printing is impaired.
[0008]
For these reasons, it has been necessary to form a recording layer that has heat insulation on the outermost surface and does not cause a difference in gloss after printing.
[0009]
[Problems to be solved by the invention]
The present inventor has good ink transferability in melt type thermal transfer recording, no dot omission in all areas from low density to high density, good dot reproducibility, and print density gradation reproducibility. An object of the present invention is to provide a thermal transfer paper that is excellent and can obtain a clear and high-resolution image with a color printer or the like and can suppress the gloss difference between a printed portion and a non-printed portion after printing as much as possible.
[0010]
As a result of intensive studies to solve the above problems, the present inventor, in the thermal transfer recording paper provided with at least one coating layer on the support, the outermost layer of the coating layer is a recording layer, 100 parts by weight of a pigment in which the recording layer comprises 30 to 80 % by weight of an inorganic pigment selected from kaolin, calcined kaolin, aluminum silicate and light calcium carbonate, and 20 to 70% by weight of a bowl-shaped organic pigment And 20 to 100 parts by weight of a binder which is a combination of styrene-butadiene copolymer latex and starch or a polyurethane resin and starch , and JIS of the recording layer P The thermal transfer recording sheet, wherein the 75 ° specular sheet gloss by 8142 method is not more than 54% has been found that the above problems can be solved.
[0011]
In one embodiment of the thermal transfer recording paper of the present invention, the bowl-shaped organic pigment has an average particle size of 0.1 to 10 μm.
[0013]
In another embodiment of the present invention, the recording layer has a Beck smoothness of 500 seconds or more according to JIS P 8119 method.
[0014]
In addition, among the inorganic pigments, the above thermal transfer recording paper in which the inorganic pigment having an oil absorption of 40 ml / 100 g or more according to JIS K 5101 method is 10 to 90% by weight of the whole pigment is also an embodiment of the present invention.
[0015]
The pigment used in the present invention preferably contains a bowl-shaped organic pigment. Here, the bowl-shaped organic pigment refers to polymer particles that have a bowl-shape under a microscope and exhibit a white color. The average particle size of these particles is preferably 0.1 to 10 μm or less. The composition of the bowl-shaped organic pigment is not particularly limited, but polymers of styrene, ethylene, vinyl chloride, acrylic and vinyl acetate or copolymers of these monomers, polymer fine particles such as polyurethane, polycarbonate, nylon and the like Examples include coalescence. From the viewpoint of heat resistance and the like, a styrene-acrylic copolymer is preferably used. If the average particle size is less than 0.1 μm, sufficient heat insulating properties, which are characteristics as an organic pigment, cannot be obtained. If the average particle size exceeds 10 μm, the unevenness of the recording layer becomes large, so that the transfer of ink is deteriorated. Two or more types having different particle sizes can be used in combination. By using a bowl-shaped organic pigment, the cushioning property of the recording layer is improved, so the adhesion and thermal insulation between the thermal head and the recording surface is improved, and the thermal energy of the thermal head is transmitted without waste, improving the color sensitivity. The effect is obtained. Also, organic pigments are softer than inorganic particles, so head wear hardly occurs, and bowl-shaped organic pigments are non-spherical, so the dent of the recording layer after passing through the thermal head is minimized. As a result, it is possible to suppress the gloss difference between the printed portion and the non-printed portion as much as possible by preventing the decrease in the glossiness. In the present invention, the blending amount of the bowl type organic pigment is preferably 10 to 70% by weight of the whole pigment. If it is less than 10% by weight, the heat insulating property and cushioning property of the recording layer are lowered, and if it exceeds 70% by weight, the gloss difference between the printed part and the non-printed part becomes large, and the appearance after printing is impaired.
[0016]
Further, the inorganic pigment used in the present invention is not particularly limited, but an inorganic pigment having an oil absorption of 40 ml / 100 g or more according to JIS K 5101 is porous and therefore absorbs the melted ink, so that ink transfer property and ink fixability are achieved. This is a preferred inorganic pigment because it improves water resistance. Examples of such inorganic pigments include calcined kaolin, magnesium hydroxide, magnesium carbonate, aluminum silicate, synthetic silica, aluminum hydroxide, and diatomaceous earth. Other inorganic pigments to be combined include calcium carbonate, clay, talc, kaolin, barium sulfate, titanium dioxide, zinc and the like, but are not particularly limited. In the present invention, the blending amount of the inorganic pigment is preferably 30 to 90% by weight of the whole pigment. If it is less than 30% by weight, the difference in gloss between the printed part and the non-printed part becomes large, and if it exceeds 90% by weight, ribbon contamination is likely to occur and head wear is large.
[0017]
As the binder used in the present invention, it is preferable to appropriately use a resin that has strong adhesion to the pigment and the base paper and does not cause blocking between papers or between the paper and the ink ribbon. A molecule etc. can be used. Examples of such binders include styrene-butadiene copolymers, modified styrene-butadiene copolymers, acrylonitrile-butadiene copolymers, methyl methacrylate-butadiene copolymers, chloroprene latex, acrylate esters and methacrylate esters. Polymer or copolymer, ethylene vinyl acetate copolymer, vinyl acetate-maleic acid ester copolymer, acrylic-vinyl acetate copolymer, vinyl acetate copolymer, starch, oxidized starch, esterified starch, enzyme-modified starch, Cellulose derivatives such as cationized starch, polyvinyl alcohol, hydroxyethyl cellulose, carboxymethyl cellulose, polyacrylamides, polyvinyl pyridine, polyethylene oxide, polyvinyl pyrrolidone, casein, al Phosphate sodium, sodium polystyrenesulfonate, starch-acrylonitrile graft polymer hydrolyzate, sulfonated chitin, can be exemplified carboxylated chitin and chitosan and their derivatives etc..
[0018]
The addition amount of the binder in the coating liquid composition is not particularly limited, but is preferably 10 to 100 parts by weight with respect to 100 parts by weight of the pigment. When the amount of the binder is less than 10 parts by weight with respect to 100 parts by weight of the pigment, the strength of the coating layer is weak, and problems such as dropping off of the coating layer and powder falling off are undesirable. On the other hand, if it exceeds 100 parts by weight, it is not preferable because the coating property deteriorates and the cost increases.
[0019]
In the coating liquid, if necessary, a dispersant, an antifoaming agent, a release agent, a pH adjusting agent, a lubricant, a water retention agent, a thickening agent, a surfactant, a fluorescent whitening agent, a coloring pigment, a coloring dye, A flow improver or the like can be appropriately selected and added.
[0020]
The thermal transfer recording paper of the present invention can be obtained by providing a coating layer of the coating solution thus adjusted by a known coating method.
The coating amount is a single layer or multilayer coating by an on-machine or off-machine coater so that the dry coating amount per side is 5 to 50 g / m 2 , preferably 7 to 35 g / m 2 . When the coating amount is less than 5 g / m 2 , it is difficult to obtain a uniform surface property because the paper surface is not sufficiently coated. Further, when the coating amount exceeds 50 g / m 2 , the cost increases, which is not preferable.
[0021]
The coating method for obtaining the recording layer is not particularly limited, and a general coating method such as a blade coater, roll coater, reverse roll coater, air knife coater, die coater, bar coater, gravure coater, curtain. Coating methods such as a coater, champleak coater, lip coater, and rod coater can be employed.
[0022]
In the present invention, the glossiness of the 75-degree specular white paper according to JIS P 8142 method of the recording layer is preferably 70% or less. By preventing the glossiness of blank paper from being increased more than necessary, it is possible to suppress the difference in glossiness between the printed portion and the non-printed portion as much as possible. When the blank paper glossiness exceeds 70%, the blank paper glossiness tends to decrease after passing through the thermal head, and a difference in glossiness between the print portion and the non-print portion tends to occur.
[0023]
Further, the Beck smoothness according to JIS P 8119 method of the recording layer is preferably 500 seconds or more. In the case where the Beck smoothness of the recording layer is 500 seconds or less, the ink transferability tends to deteriorate due to an increase in the unevenness of the coating layer surface.
In the present invention, there is no particular need for an intermediate layer, and it has good thermal transfer characteristics.However, there is no problem even if an intermediate layer is provided, as long as the outermost recording layer is formed as described above. good.
[0024]
As the support, acidic and neutral high-quality paper, medium-quality paper, or the like can be used, but it is preferable to use a support having coating suitability as a coating base paper.
The thermal transfer recording paper of the present invention can be smoothed by a known pressurizing apparatus such as a super calender or a soft calender after the recording layer is applied for the purpose of improving the appearance and smoothness. Further, if necessary, the back surface can be subjected to antistatic treatment, treatment for imparting slipperiness, tack processing, and the like.
[0025]
【The invention's effect】
As described above in detail, the thermal transfer recording paper of the present invention has good ink transferability, and the thermal energy applied to the thermal head has no dot dropout in all regions from low density to high density, resulting in dot reproducibility. Good, good print density gradation reproducibility, no ribbon stains, good head wear, can provide clear high resolution images, and gloss difference between printed and non-printed areas Can be suppressed as much as possible, and is particularly suitable as a thermal transfer recording paper for a melt-type thermal transfer printer.
