Description
本発明は、鏡面光沢、カラー鏡面光沢を備えた印刷物の製造に用いる高輝度鏡面性を有するスクリーン印刷用のインキ、およびそのインキによりスクリーン印刷が施された印刷物、樹脂成形物に関する。 The present invention relates to an ink for screen printing having high-brightness specularity used for manufacturing a printed material having a specular gloss and a color specular gloss, a printed material on which screen printing is performed with the ink, and a resin molded product.
鏡面光沢を有する印刷物を製造する際、鱗片状アルミニウム、箔状アルミニウムなどの各種アルミニウム素材を添加したインキを用いることが従来から知られているが、この種のインキを用いてスクリーン印刷を行った場合、印刷物に対しての密着性が劣ると共に、印刷物にギザ、カスレ、ピンホール、透け等の欠陥が発生するという問題があり、安定した鏡面光沢、カラー鏡面光沢を得ることが困難であった。
したがって、密着性が有り、印刷適正の良い、安定した鏡面光沢やカラー鏡面光沢を発現できるスクリーン印刷用の鏡面インキが望まれていた。
ここで言う印刷適正の良い鏡面インキとは、印刷物におけるギザ、カスレ、ピンホール、透け等の欠陥の発生が非常に少ないもので有って、且つ印刷素材（基材）に対して密着性の良い高輝度鏡面スクリーンインキを意味している。
When manufacturing a printed matter having a specular gloss, it is conventionally known to use ink added with various aluminum materials such as scale-like aluminum and foil-like aluminum, but screen printing was performed using this kind of ink. In this case, there is a problem that adhesion to the printed material is inferior and defects such as burrs, blurring, pinholes, and see-through are generated in the printed material, and it is difficult to obtain stable specular gloss and color specular gloss. .
Therefore, there has been a demand for a mirror-surface ink for screen printing that has adhesiveness and good printability and can exhibit stable mirror gloss and color mirror gloss.
Mirror surface ink with good printability mentioned here is one that has very few defects such as burrs, scrapes, pinholes, and see-through in printed matter, and has good adhesion to the printing material (base material). Means good high brightness specular screen ink.
前述の要望に対応するために、例えば特許文献１には、真空蒸着法で得られたアルミニウム箔１００重量部に対し、所定量のバインダーポリマーと溶剤を含んでなるインキが提案されている。 In order to meet the above-mentioned demand, for example, Patent Document 1 proposes an ink containing a predetermined amount of a binder polymer and a solvent with respect to 100 parts by weight of an aluminum foil obtained by a vacuum deposition method.
しかし、前記従来のインキを用いてスクリーン印刷を行った場合、印刷適正や密着性に問題が残り、高輝度の鏡面光沢を備えた鏡面印刷物、カラー鏡面印刷物を得るのは困難であった。 However, when screen printing is performed using the above-described conventional ink, problems remain in printing suitability and adhesion, and it is difficult to obtain a mirror print or a color mirror print with a high-brightness mirror gloss.
すなわち、従来の鏡面インキは、所定サイズのアルミニウム箔を含有することで鏡面性の向上を図っているが、該アルミニウム箔に対するバインダーポリマーや溶剤の相性、印刷素材（基材）に対するアルミニウム箔，バインダーポリマー，溶剤同士の相性、印刷素材に既存のインキや塗料等による印刷面上に鏡面印刷をする際の前記印刷面に対するアルミニウム箔，バインダーポリマー，溶剤同士の相性といった技術事項については詳細に検討されておらず、このような技術事項が、印刷物にギザ、カスレ、ピンホール、透け等の欠陥が発生する要因となると共に、印刷後の塗膜の密着性と鏡面性を同時に発現させることを難しくし、結果として印刷適正が劣ると推定される。 That is, the conventional mirror surface ink is intended to improve the specularity by containing an aluminum foil of a predetermined size, but the compatibility of the binder polymer and solvent with the aluminum foil, the aluminum foil and binder with respect to the printing material (base material) Technical matters such as compatibility between polymers and solvents, and compatibility between aluminum foil, binder polymer and solvents on the printing surface when printing on the printing surface with existing ink or paint on the printing material have been studied in detail. However, such technical matters cause defects such as burrs, scrapes, pinholes, and see-through in printed materials, and it is difficult to simultaneously develop adhesion and specularity of the coated film after printing. As a result, it is estimated that printing suitability is inferior.
また、近年においては、密着性などをあげるために表面処理されたポリエチレンテレフタレート等からなる印刷素材（基材）に対して、安定した印刷適正を発現できる高輝度鏡面スクリーンインキが望まれている。しかし、前記した従来の鏡面インキを用いてスクリーン印刷を行った場合、前述の理由等により、高度な鏡面性と密着性を得ることができないという問題があった。 In recent years, there has been a demand for a high-brightness specular screen ink capable of expressing stable printing suitability for a printing material (base material) made of polyethylene terephthalate or the like that has been surface-treated to improve adhesion. However, when screen printing is performed using the above-described conventional specular ink, there is a problem that high specularity and adhesion cannot be obtained due to the reasons described above.
また、既存のインキや塗料などを使用して印刷が施された上に鏡面インキを用いて重ね印刷を施すと、重ねて印刷された部分が侵されて密着性、色相に影響を与えるという問題があった。 In addition, if printing is performed using existing ink or paint, and overprinting is performed using specular ink, the overprinted portion is affected and affects adhesion and hue. was there.
本発明はこのような従来事情に鑑みてなされたもので、その主たる目的とする処は、安定した印刷適正を有し、且つ高度な鏡面光沢、カラー鏡面光沢を発現する印刷物を製造し得る高輝度鏡面スクリーンインキを提供することである。
また、本発明の他の目的は、スクリーン印刷において高度な鏡面性と密着性を同時に満たすことが困難な素材である、表面処理されたポリエチレンテレフタレート等の基材に対しても、高度な鏡面性と密着性を発現する印刷物を製造し得る高輝度鏡面スクリーンインキを提供することである。
また、本発明の他の目的は、既存のインキや塗料の印刷された印刷物の上に重ねて印刷しても、該重ねて印刷された部分が侵されて密着性、色相に影響を与えることがなく、安定した印刷適正を有し、且つ高度な鏡面光沢、カラー鏡面光沢を発現する高輝度鏡面スクリーンインキを提供することである。
また、本発明の他の目的は、表面に高輝度鏡面部分を有する合成樹脂成形体を容易に得ることにある。
The present invention has been made in view of such conventional circumstances, and the main purpose of the present invention is to provide a print product that has stable printing suitability and can exhibit high specular gloss and color specular gloss. It is to provide a brightness mirror screen ink.
Another object of the present invention is to provide a high degree of specularity for a substrate such as surface-treated polyethylene terephthalate, which is a material that is difficult to simultaneously satisfy high specularity and adhesion in screen printing. It is to provide a high-intensity specular screen ink that can produce a printed matter exhibiting adhesiveness.
In addition, another object of the present invention is that even if printing is performed on a printed material on which an existing ink or paint is printed, the overlapping printed portion is affected to affect adhesion and hue. It is an object of the present invention to provide a high-brightness specular screen ink that has a stable printability and exhibits high specular gloss and color specular gloss.
Another object of the present invention is to easily obtain a synthetic resin molded body having a high-brightness mirror surface portion on the surface.
以上の目的を達成するために、本願発明者は、鏡面インキの主たる原材料であるアルミニウム素材、溶剤、バインダーポリマーに着目して鋭意研究を重ね、アルミニウム素材として表面の平滑性に優れる蒸着アルミニウム顔料を用いると共に、所定の条件を備えた溶剤とバインダーポリマーを選択して組み合わせることが、前述の課題に対し極めて有効であることを知見し、本発明を完成するに至った。 In order to achieve the above object, the inventor of the present application has repeatedly studied earnestly focusing on aluminum materials, solvents, and binder polymers, which are the main raw materials of specular ink, and has developed a vapor deposited aluminum pigment that is excellent in surface smoothness as an aluminum material. It was found that it was extremely effective to use and combine a solvent having a predetermined condition and a binder polymer in combination with the aforementioned problems, and the present invention was completed.
すなわち、本発明に係る高輝度鏡面スクリーンインキは、蒸着アルミニウム顔料：１００重量部に対し、少なくとも、バインダーポリマーとしてブチラール系樹脂：１〜８重量部と塩化ビニル・酢酸ビニルコポリマー：１０〜１００重量部、溶剤：６００〜２０００重量部を含み、前記溶剤が、イソホロン：５０〜２５０重量部、コハク酸ジメチル・グルタミン酸ジメチル・アジピン酸ジメチルの混合物：５０〜２５０重量部、グリコールエーテル系溶剤：残部（５００〜１５００重量部）であることを特徴とする。 That is, the high-intensity specular screen ink according to the present invention has at least 1 to 8 parts by weight of a butyral resin as a binder polymer and 10 to 100 parts by weight of a vinyl chloride / vinyl acetate copolymer as a binder polymer with respect to 100 parts by weight of the deposited aluminum pigment. , Solvent: 600 to 2000 parts by weight, the solvent is isophorone: 50 to 250 parts by weight, a mixture of dimethyl succinate / dimethyl glutamate / dimethyl adipate: 50 to 250 parts by weight, glycol ether solvent: remainder (500 ˜1500 parts by weight).
このような構成になる本発明の高輝度鏡面スクリーンインキは、表面の平滑性に優れる蒸着アルミニウム顔料を用いると共に、スクリーン印刷用としての有機溶剤の中から、イソホロン：５０〜２５０重量部、コハク酸ジメチル・グルタミン酸ジメチル・アジピン酸ジメチルの混合物：５０〜２５０重量部、グリコールエーテル系溶剤：５００〜１５００重量部を含有し、且つバインダーポリマーとしてブチラール系樹脂：１〜８重量部と塩化ビニル・酢酸ビニルコポリマー：１０〜１００重量部を含有することから、印刷基材に対する密着性に優れると共に印刷物におけるギザ、カスレ、ピンホール、透け等の欠陥の発生が非常に少なく、印刷適正に優れると共に安定した鏡面光沢やカラー鏡面光沢を発現する印刷物を製造することができる。 The high-intensity specular screen ink of the present invention having such a configuration uses a vapor-deposited aluminum pigment excellent in surface smoothness, and from an organic solvent for screen printing, isophorone: 50 to 250 parts by weight, succinic acid Mixture of dimethyl / dimethyl glutamate / dimethyl adipate: 50 to 250 parts by weight, glycol ether solvent: 500 to 1500 parts by weight, and butyral resin as binder polymer: 1 to 8 parts by weight and vinyl chloride / vinyl acetate Copolymer: Since it contains 10 to 100 parts by weight, it has excellent adhesion to the printing substrate and has very few defects such as burrs, blurring, pinholes, and see-through in the printed matter, and it has excellent printing suitability and a stable mirror surface. Can produce printed materials that exhibit gloss and color specular gloss .
前記溶剤としてのイソホロンの含有量が５０重量部未満、又は、コハク酸ジメチル・グルタミン酸ジメチル・アジピン酸ジメチルの混合物の含有量が５０重量部未満では、前記バインダーポリマーに対する溶解力が十分でなく、印刷適正が悪くなる。
また、イソホロンの含有量が２５０重量部を超えた場合、又は、コハク酸ジメチル・グルタミン酸ジメチル・アジピン酸ジメチルの混合物の含有量が２５０重量部を越えた場合、既存のインキや塗料で印刷された印刷物の上に重ねて印刷された部分が侵されて密着性、色相に影響を与える。
グリコールエーテル系溶剤が５００重量部未満では、インキ粘度が高く印刷適正が悪くなり、印刷面にギザ、カスレ、ピンホールが発生し、１５００重量部を超えるとインキ粘度が低く印刷適正が悪くなり、印刷面にダレ、ギザ、カスレ、ピンホールが発生する。
また、ブチラール系樹脂の含有量が１重量部未満では、印刷適正が悪く、印刷物におけるギザ、カスレ、ピンホール、透け等の欠陥が発生する。ブチラール系樹脂の含有量が８重量部を超えると、塗膜性能が低下して、インサート成形や重ね印刷をした場合に密着性、色相に影響を与える。
塩化ビニル・酢酸ビニルコポリマーの含有量が１０重量部未満では、基材に対する密着性が低下し、１００重量部を超えると印刷面の鏡面性が低下する。
When the content of isophorone as the solvent is less than 50 parts by weight, or the content of the mixture of dimethyl succinate / dimethyl glutamate / dimethyl adipate is less than 50 parts by weight, the solvent has insufficient solvent power and printing. Properness gets worse.
In addition, when the content of isophorone exceeded 250 parts by weight, or when the content of the mixture of dimethyl succinate / dimethyl glutamate / dimethyl adipate exceeded 250 parts by weight, it was printed with an existing ink or paint. The part printed over the printed material is affected, affecting the adhesion and hue.
If the glycol ether solvent is less than 500 parts by weight, the ink viscosity is high and printing suitability is poor, and the printed surface has burrs, scrapes and pinholes. If it exceeds 1500 parts by weight, the ink viscosity is low and printing suitability is poor, Sag, jagged edges, scrapes and pinholes occur on the printed surface.
On the other hand, when the content of the butyral resin is less than 1 part by weight, the printing suitability is poor, and defects such as burrs, blurring, pinholes and show-through in printed matter occur. When the content of the butyral resin exceeds 8 parts by weight, the coating film performance is deteriorated, and the adhesiveness and hue are affected when insert molding or overprinting is performed.

When the thickness of the vapor-deposited aluminum pigment exceeds 0.5 μm, or when the area of the vapor-deposited aluminum pigment is less than 20 μm 2, it is difficult to obtain a printed matter having a higher brightness specular gloss.
When the area of the vapor-deposited aluminum pigment exceeds 2000 μm 2 , defects such as burrs, blurring, pinholes, and see-through may occur in the printed matter.
本発明に係る高輝度鏡面スクリーンインキのインキ粘度は、１００〜２５００ｃｐｓ（測定温度３０℃においてＥ型回転粘度計により回転数１００ｒ.ｐ.ｍで測定。本明細書中では単に「３０℃」と表記する。）であることが好ましい。
この場合、印刷適正がより向上し、安定した鏡面光沢やカラー鏡面光沢を発現するより高輝度の鏡面印刷物を製造することができる。
インキ粘度が１００ｃｐｓ未満である場合、又は２５００ｃｐｓを超える場合は、印刷物にギザ、カスレ、ピンホール、透け等の欠陥が発生する虞れがあり、印刷適正が低下する虞れがある。
The ink viscosity of the high-intensity specular screen ink according to the present invention is 100 to 2500 cps (measured at a measurement temperature of 30 ° C. with an E-type rotational viscometer at a rotation speed of 100 rpm). It is preferable that
In this case, it is possible to manufacture a higher-brightness mirror surface printed matter with improved printing suitability and exhibiting stable mirror surface gloss and color mirror surface gloss.
When the ink viscosity is less than 100 cps or more than 2500 cps, there is a possibility that defects such as jaggedness, blurring, pinholes, and see-through may occur in the printed matter, and the printability may be lowered.
また、上記蒸着アルミニウム顔料：１００重量部に対し、着色顔料及び／又はパール顔料を１５０重量部以下の範囲で含んでも良い。この場合、各種の色彩を持ちながら高度な鏡面光沢を発現する印刷物を製造することができる。 Moreover, you may contain a coloring pigment and / or a pearl pigment in 150 weight part or less with respect to said vapor deposition aluminum pigment: 100 weight part. In this case, it is possible to produce a printed matter that exhibits various specular gloss while having various colors.
また、上記蒸着アルミニウム顔料：１００重量部に対し、蒸着アルミニウム顔料を製造するときに混入される溶剤、及び／又はバインダーポリマーを溶解する溶剤が２５０重量部以下の範囲で含まれても良い。
但し、バインダーポリマーを溶解する溶剤として、バインダーポリマーに対して溶解力の無い、所謂助溶剤や希釈剤よりも沸点の高い溶剤を用いる方が好ましい。助溶剤や希釈剤よりも沸点の低い溶剤を用いると、印刷作業中の時間経過に伴いインキ粘度が2500cpsを超えて、印刷物にギザ、カスレ、ピンホール、透け等の欠陥を発生する虞れがあり、印刷適正が低下する虞れがある。しかし、上記基本配合に使用する溶剤がバインダーポリマーを溶解する場合はこの限りでない。
Moreover, the solvent mixed when manufacturing a vapor deposition aluminum pigment and / or the solvent which melt | dissolves a binder polymer with respect to said vapor deposition aluminum pigment: 100 weight part may be contained in 250 weight part or less.
However, it is preferable to use a solvent having a boiling point higher than that of a so-called co-solvent or diluent, which does not dissolve the binder polymer, as the solvent for dissolving the binder polymer. If a solvent with a boiling point lower than that of the co-solvent or diluent is used, the ink viscosity will exceed 2500 cps over time during the printing operation, which may cause defects such as burrs, scrapes, pinholes, and see-through on the printed matter. There is a possibility that the printing suitability is lowered. However, this is not the case when the solvent used in the basic composition dissolves the binder polymer.
また、本発明に係る高輝度鏡面スクリーンインキは、印刷素材としての基材が、密着性などをあげるために表面処理されたポリエチレンテレフタレート（例えば、東洋紡績(株)社製のCosmoshine A4100，A4300等、東山フィルム(株)社製のHK-31WF，CHCハードコート等）等に対しても所定の効果を得ることができる。 In addition, the high-intensity specular screen ink according to the present invention is a polyethylene terephthalate (for example, Cosmoshine A4100, A4300 manufactured by Toyobo Co., Ltd., etc.) whose surface as a printing material is surface-treated in order to increase adhesion. A predetermined effect can also be obtained for HK-31WF manufactured by Higashiyama Film Co., Ltd., CHC hard coat and the like.
但し、これら基材は、より高度な鏡面性と密着性を得ることが困難であるので、前記したグリコールエーテル系溶剤の中でも、メチルイソブチルカルビノール、エチレングリコールジブチルエーテル、エチレングリコールモノフェニルエーテル、エチレングリコールモノブチルエーテル、エチレングリコールモノヘキシルエーテル、エチレングリコールモノメトキシメチルエーテル、ジエチレングリコールエチルメチルエーテル、ジエチレングリコールジエチルエーテル、ジエチレングリコールジメチルエーテル、ジエチレングリコールモノエチルエーテル、ジエチレングリコールモノブチルエーテル、ジエチレングリコールモノメチルエーテル、ジプロピレングリコールモノエチルエーテル、ジプロピレングリコールモノブチルエーテル、ジプロピレングリコールモノメチルエーテル、トリエチレングリコールジメチルエーテル、トリエチレングリコールモノメチルエーテル、プロピレングリコールモノエチルエーテル、プロピレングリコールモノブチルエーテル、プロピレングリコールモノメチルエーテル、3-メチル-3-メトキシ-1-ブタノール、エチレングリコールジエチルエーテル、エチレングリコールジグリシジルエーテル、エチレングリコールモノイソプロピルエーテル、エチレングリコールモノエチルエーテル、エチレングリコールモノメチルエーテル、ジプロピレングリコールモノプロピルエーテルを用いることが好ましい。
これらグリコールエーテル系溶剤を単独で又は複数混合して、５００〜１５００重量部の範囲で含むことが好ましい。
However, since these substrates are difficult to obtain higher specularity and adhesion, among the above-mentioned glycol ether solvents, methyl isobutyl carbinol, ethylene glycol dibutyl ether, ethylene glycol monophenyl ether, ethylene Glycol monobutyl ether, ethylene glycol monohexyl ether, ethylene glycol monomethoxymethyl ether, diethylene glycol ethyl methyl ether, diethylene glycol diethyl ether, diethylene glycol dimethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, diethylene glycol monomethyl ether, dipropylene glycol monoethyl ether, diethylene glycol Propylene glycol monobutyl ether, Propylene glycol monomethyl ether, triethylene glycol dimethyl ether, triethylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, propylene glycol monomethyl ether, 3-methyl-3-methoxy-1-butanol, ethylene glycol diethyl ether, ethylene Glycol diglycidyl ether, ethylene glycol monoisopropyl ether, ethylene glycol monoethyl ether, ethylene glycol monomethyl ether, dipropylene glycol monopropyl ether are preferably used.
These glycol ether solvents are preferably contained alone or in combination in a range of 500 to 1500 parts by weight.
これら溶剤を用いた場合、前記基材に対し、より高度な鏡面性と密着性を発現し、印刷適正が良く安定した鏡面光沢やカラー鏡面光沢を有する高輝度鏡面印刷物を製造することができる。また、既存のスクリーンインキや塗料などを使用して印刷が施された印刷物に対しても同様の効果を発揮し、これら印刷物の上に一部が重なるよう高輝度鏡面印刷することができる。 When these solvents are used, it is possible to produce a high-intensity specular printed material that exhibits a higher degree of specularity and adhesion to the substrate, and has a good specularity and stable specular gloss and color specular gloss. Moreover, the same effect is exhibited with respect to the printed matter printed using the existing screen ink, paint, etc., and high-intensity mirror surface printing can be performed so that a part overlaps these printed matter.
なお、本発明に係る高輝度鏡面スクリーンインキは、必要に応じて、スクリーンインキに添加可能なレベリング剤や沈降防止剤などの各種添加剤、インキ粘度を調整するための低沸点の溶剤等を含むことができる。
但し、溶剤以外の各種添加剤の含有量は、インキ全体量の１％以下であることが望ましい。各種添加剤の１％以上の添加は、鏡面性が低下する虞れがある。
The high-intensity specular screen ink according to the present invention includes various additives such as a leveling agent and an anti-settling agent that can be added to the screen ink, a low boiling point solvent for adjusting the ink viscosity, and the like, if necessary. be able to.
However, the content of various additives other than the solvent is desirably 1% or less of the total amount of the ink. When 1% or more of various additives is added, the specularity may be lowered.
本発明に係る高輝度鏡面スクリーンインキは以上説明したような組成としたので、通常のスクリーン印刷によって安定的に鏡面光沢、カラー鏡面光沢を発現できる。しかも、ギザ、カスレ、ピンホール、透け等の欠陥の発生が非常に少なく、印刷適正も良いことから、印刷効率が格段に高まることにより、安価で品質の良い鏡面光沢、カラー鏡面光沢を持つ印刷物を製造することができる。 Since the high-intensity specular screen ink according to the present invention has the composition as described above, it can stably exhibit specular gloss and color specular gloss by ordinary screen printing. In addition, since there are very few defects such as burrs, scrapes, pinholes, and see-through, and printing is very good, the printing efficiency is dramatically increased, resulting in low-quality and high-quality specular gloss and color specular gloss. Can be manufactured.
また、密着性などをあげるために表面処理されたポリエチレンテレフタレート等の基材に対しても、高度な鏡面性と密着性を発現することができる。 In addition, high specularity and adhesion can be expressed even on a substrate such as polyethylene terephthalate which has been surface-treated in order to improve adhesion.
また、既存のインキや塗料で印刷された印刷物の上に重ねて印刷しても、重ねて印刷された部分が侵されて密着性、色相に影響を与えることがなく、安定した印刷適正を有し、且つ高度な鏡面光沢、カラー鏡面光沢を発現するなどの効果を奏する。 In addition, even if you print on top of a printed material that has been printed with existing ink or paint, the overprinted portion will not be affected, affecting adhesion and hue, and ensuring stable printing. In addition, there are effects such as developing a high level of specular gloss and color specular gloss.
また、本発明に係る高輝度鏡面スクリーンインキを用いてポリエチレンテレフタレートなどの透明又は半透明の合成樹脂フィルムやシートの裏面に印刷を施し、該印刷が施されたシートの前記裏面側に、インサート成形や他の成形法により合成樹脂成形体を一体成形することで、表面に高度な鏡面光沢、カラー鏡面光沢を発現する樹脂成形物を容易に得ることができる。 Further, using the high-intensity specular screen ink according to the present invention, printing is performed on the back side of a transparent or translucent synthetic resin film or sheet such as polyethylene terephthalate, and insert molding is performed on the back side of the printed sheet. In addition, by integrally molding the synthetic resin molded body by other molding methods, it is possible to easily obtain a resin molded product that exhibits high specular gloss and color specular gloss on the surface.
