Description
本発明は、オフセット印刷インキ組成物およびこれを用いた印刷物に関する。 The present invention relates to an offset printing ink composition and a printed matter using the same.
紙等の浸透性の基材に印刷する際、印刷インキ組成物が乾燥するにつれて基材に浸透していき、印刷直後に比べて印刷濃度が低下するいわゆるドライダウンという現象が生じることが知られている。
ドライダウンの程度を左右する要因の一つとして基材が挙げられ、一般にコート紙やマットコート紙等の塗工紙よりも上質紙等の非塗工紙の方が大きくなる傾向にある。新聞印刷や週刊誌等に用いられる紙では、原料の大部分が繊維の短い古紙であり、また軽量化やコストダウンを目的として減斤化が進められていることもあって印刷インキが浸透しやすく、ドライダウンの程度もより大きい。
When printing on a permeable substrate such as paper, it is known that the phenomenon of so-called dry-down occurs in which the substrate penetrates into the substrate as the printing ink composition dries, and the printing density decreases compared to that immediately after printing. ing.
One of the factors affecting the degree of dry-down is a base material, and in general, non-coated paper such as high-quality paper tends to be larger than coated paper such as coated paper and matte coated paper. In the case of paper used in newspaper printing and weekly magazines, the majority of the raw material is waste paper with short fibers, and there is also progress in reduction for weight reduction and cost reduction, and therefore printing ink penetrates Easy, the degree of dry down is also greater.
このようなドライダウンを抑制するための試みとして、特許文献１では坪量が４６ｇ／ｍ２以下の紙基材に対して、一次粒子径が１０ｎｍ以上５００ｎｍ以下でかつ真比重が２．０以上５．０以下の体質顔料を１〜４０重量％含有する平版印刷インキを用いて印刷することが提案されている。
しかしながら、オフセット印刷インキ組成物に体質顔料として広く用いられている炭酸カルシウムは一般的に、一次粒子径が１０ｎｍ以上５００ｎｍ以下でかつ真比重は２．０以上５．０以下であるから、特許文献１に記載の印刷物は従来技術の域を出ない。
As an attempt to suppress such dry-down, in Patent Document 1, the primary particle diameter is 10 nm to 500 nm and the true specific gravity is 2.0 or more with respect to the paper base having a basis weight of 46 g / m 2 or less. It is proposed to print using a lithographic printing ink containing 1 to 40% by weight of an extender pigment of 5.0 or less.
However, calcium carbonate widely used as an extender pigment in offset printing ink compositions generally has a primary particle diameter of 10 nm to 500 nm and a true specific gravity of 2.0 to 5.0. The printed material described in 1 does not go beyond the prior art.
ドライダウンが生じることを見越して、印刷から所定時間経過した後の印刷濃度が所望の値となるよう、印刷に用いるインキ量を例えば５％〜１０％増やして印刷することが行われているが、新聞印刷や週刊誌等に用いられるような紙に対してインキ量を増やして印刷すると、裏抜けが生じ易くなるという問題がある。 In anticipation of the occurrence of dry-down, the amount of ink used for printing is increased by, for example, 5% to 10%, and printing is performed so that the print density after a predetermined time has elapsed since printing becomes a desired value. If the amount of ink is increased for printing such as that used for newspaper printing, weekly magazines, etc., there is a problem that strike-through tends to occur.
本発明はこのような事情に鑑みなされたものであって、浸透性の基材、特に新聞印刷や週刊誌等に用いられるような紙を用いてオフセット印刷した際に、ドライダウンを抑制可能なオフセット印刷インキ組成物を提供することを目的とする。また、ドライダウンが抑制された印刷物を提供することを目的とする。 The present invention has been made in view of such circumstances, and can suppress dry-down when offset printing is performed using a permeable substrate, in particular, paper used for newspaper printing, weekly magazines, etc. An object of the present invention is to provide an offset printing ink composition. Another object of the present invention is to provide a printed material in which dry-down is suppressed.
本発明者らは鋭意検討の結果、一次粒子径が異なる２種類以上の体質顔料を用いることによりドライダウンが抑制されることを見出し、本発明を完成した。本発明は以下の形態または適用例として実現することが可能である。
（適用例１）
本適用例に係るオフセット印刷インキ組成物は、顔料と、体質顔料と、樹脂成分と、溶剤とを含み、体質顔料は、一次粒子径が３ｎｍ以上２０ｎｍ未満の第１体質顔料と、一次粒子径が２０ｎｍ以上２００ｎｍ未満の第２体質顔料とを含むことを特徴とする。
このような印刷インキ組成物は、印刷物のドライダウンを効果的に抑制することができる。
（適用例２）
上記適用例に係るオフセット印刷インキ組成物において、第１体質顔料の含有量が、０．３質量％以上５質量％以下であることが好ましい。
As a result of intensive studies, the present inventors have found that dry-down can be suppressed by using two or more types of extender pigments having different primary particle diameters, and completed the present invention. The present invention can be realized as the following modes or application examples.
Application Example 1
The offset printing ink composition according to this application example includes a pigment, an extender pigment, a resin component, and a solvent, and the extender pigment has a primary particle diameter of 3 nm or more and less than 20 nm, and a primary particle diameter. And the second body pigment of 20 nm or more and less than 200 nm.
Such a printing ink composition can effectively suppress the dry-down of the printed matter.
Application Example 2

本明細書において体質顔料の一次粒子径とは、透過型電子顕微鏡観察により粒子径を測定し、平均した値であり、少なくとも８０％以上の粒子がその範囲に入る値を指す。
The offset printing ink composition of the present invention contains, as an extender pigment, a first extender pigment having a primary particle diameter of 3 nm or more and less than 20 nm and a second extender pigment having a primary particle diameter of 20 nm or more and less than 200 nm. Furthermore, a third body pigment having a primary particle diameter of 200 nm or more and 400 nm or less may be included. By using the first body pigment and the second body pigment in combination, it is possible to suppress the dry-down and the strike-through of the printed matter.
In the present specification, the primary particle size of the extender pigment is a value obtained by measuring the particle size by observation with a transmission electron microscope and averaging the value, and refers to a value in which particles of at least 80% or more fall within the range.
体質顔料としては、一次粒子径がそれぞれ上述した範囲にあるものであれば特に限定されず、ろう石クレー等のクレー、タルク、硫酸バリウム、炭酸カルシウム、重質炭酸カルシウム、炭酸バリウム、シリカ、ベントナイト、酸化チタン等、公知のものを１種類または２種類以上用いることができる。これらの体質顔料は、ロジン酸などにより表面処理されていてもよいし、未処理であってもよい。 The extender pigment is not particularly limited as long as the primary particle diameter is in the above-mentioned range, and clay such as wax clay, talc, barium sulfate, calcium carbonate, calcium carbonate, barium carbonate, silica, bentonite One or two or more known ones such as titanium oxide can be used. These extender pigments may be surface-treated with rosin acid or the like, or may be untreated.
第１体質顔料の添加量は、印刷インキ組成物の全重量の０．３質量％以上５．０質量％以下であることが好ましく、０．５質量％以上３．５質量％以下であることがより好ましい。第１体質顔料の添加量が０．３質量％を下回るとドライダウンを抑制する効果が薄くなる。５質量％を越えるとドライダウンは好適に抑制できる一方、着肉性が悪化し始める。
第２体質顔料の添加量は、印刷インキ組成物の１質量％以上２４．７質量％以下であることが好ましく、３質量％以上１０質量％以下であることがより好ましい。第３体質顔料をさらに含む場合は、第３体質顔料の添加量は、印刷インキ組成物の１質量％以上２３．７質量％以下であることが好ましく、３質量％以上１０質量％以下であることがより好ましい。
The addition amount of the first extender pigment is preferably 0.3% by mass or more and 5.0% by mass or less of the total weight of the printing ink composition, and 0.5% by mass or more and 3.5% by mass or less Is more preferred. When the addition amount of the first extender pigment is less than 0.3% by mass, the effect of suppressing the dry-down becomes thin. If it exceeds 5% by mass, the dry-down can be suitably suppressed, but the inking property starts to deteriorate.
The addition amount of the second body pigment is preferably 1% by mass or more and 24.7% by mass or less of the printing ink composition, and more preferably 3% by mass or more and 10% by mass or less. When the third body pigment is further contained, the addition amount of the third body pigment is preferably 1% by mass or more and 23.7% by mass or less, and is 3% by mass or more and 10% by mass or less of the printing ink composition. Is more preferred.
他の体質顔料をさらに含んでいてもよいが、第１体質顔料および第２体質顔料、必要に応じて用いられる第３体質顔料を含むこれらの体質顔料の添加量の合計は、印刷インキ組成物の７質量％以上であって、２５質量％を越えない範囲であることが好ましい。添加量の合計が７質量％を下回るとドライダウンを抑制する効果が薄くなり、２５質量％を越えると印刷インキ組成物が固くなりすぎ、印刷適性に欠ける場合がある。 The total added amount of these extender pigments including the first extender pigment and the second extender pigment, and optionally the third extender pigment, which may further include other extender pigments, is a printing ink composition. It is preferable that it is a 7 mass% or more of, and the range which does not exceed 25 mass%. When the total addition amount is less than 7% by mass, the effect of suppressing the dry-down becomes weak, and when it exceeds 25% by mass, the printing ink composition may become too hard and lack in printability.
一例として、第１体質顔料としてシリカ、炭酸カルシウムから選ばれる少なくとも１種、第２体質顔料として炭酸カルシウム、酸化チタンから選ばれる少なくとも１種、第３体質顔料として、クレー、タルク、重質炭酸カルシウム、硫酸バリウムから選ばれる少なくとも１種を用いることが好ましい。中でも、第１体質顔料としてシリカを用い、第２体質顔料として炭酸カルシウムを用いた印刷インキ組成物はドライダウン抑制効果が大きくなるためより好ましい。 As an example, at least one member selected from silica and calcium carbonate as the first body pigment, and at least one member selected from calcium carbonate and titanium oxide as the second body pigment, clay, talc and ground calcium carbonate as the third body pigment It is preferable to use at least one selected from barium sulfate and barium sulfate.
