Description
【０００１】
【発明の属する技術分野】
本発明は、基材表面に被覆剤を、ハジキや膜厚ムラの生じにくい状態で転写する方法及び基材への転写用被覆剤に関するものである。
【０００２】
【従来の技術】
従来から、プラスチック、紙、金属、木材、無機質等の各種素材からなる基材表面に、装飾、画像、機能性等を付与する目的で各種被覆剤が、印刷もしくは塗装されている。その印刷、塗装手段の一つとして、転写方法が知られている。
【０００３】
ところで、シート状、フィルム状あるいは板状の基材表面に被覆剤を転写する際、しばしば膜厚ムラやハジキが生じ易く、それを解消するため、通常、基材表面を特定の表面処理剤で予め処理したり、被覆剤に消泡剤や粘度調整剤等の各種添加剤を配合して解決していた。しかしながら、基材表面を表面処理剤で処理する方法は、処理工程が増え、またコストの面でも問題があり、更に、基材の種類毎に表面処理剤を開発する必要があり、それでもしばしば膜厚ムラやハジキ等が生じる問題があった。また、添加剤等を配合する方法も基材の種類に応じて被覆剤を配合設計しないと同様な問題がしばしば発生しており、更に、添加剤を多く配合すると膜性能に悪影響を及ぼす恐れがあった。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、このような従来技術の課題を背景になされたもので、膜厚ムラや、ハジキの生じにくい転写方法及び転写用被覆剤を提供することにある。
【０００５】
【課題を解決するための手段】
本発明に従って、基材表面に、バインダー樹脂及び溶剤を必須成分として含有する被覆剤を転写する方法において、該被覆剤は、２０℃における粘度が１００ｍＰａ・ｓ以下であり、かつ、静置状態における表面張力が２８ｍＮ／ｍ以下であり、更に、静置状態における表面張力が１７〜２７ｍＮ／ｍの溶剤を、該被覆剤中の全溶剤に対して５〜１００質量％の範囲で含有することを特徴とする転写方法が提供される。
【０００６】
また、本発明に従って、基材表面に転写するための、必須成分としてバインダー樹脂及び溶剤を含有する被覆剤において、該被覆剤は、２０℃における粘度が１００ｍＰａ・ｓ以下であり、かつ、静置状態における表面張力が２８ｍＮ／ｍ以下であり、更に、静置状態における表面張力が１７〜２７ｍＮ／ｍの溶剤を、該被覆剤中の全溶剤に対して５〜１００質量％の範囲で含有することを特徴とする転写用被覆剤が提供される。
【０００７】
【発明の実施の形態】
本発明者らは、上記課題を解決するため鋭意検討した結果、転写される被覆剤として、特定の粘度と表面張力を有し、更に、特定の表面張力を有する溶剤を含有する被覆剤を使用することにより、上記課題が達成できることを見出し、本発明に到達したものである。
【０００８】
本発明で使用する被覆剤は、バインダー樹脂（必要に応じてその硬化剤併用）、それを溶解、もしくは安定に分散させるための溶剤を必須成分として含み、更に必要に応じて、通常、塗料やインクに使用されている着色顔料、体質顔料、染料、等の染顔料；分散剤、粘度調整剤、酸化防止剤、紫外線吸収剤、帯電防止剤、硬化促進剤等の各種添加剤を配合したものから構成される。
【０００９】
上記バインダー樹脂としては、通常、塗料やインクに使用されているものが特に制限なく利用可能であるが、具体的には、例えば、エポキシ樹脂や、ポリエステル樹脂、アクリル樹脂、シリコーン樹脂、アルキッド樹脂、ウレタン樹脂、フッ素樹脂、あるいはこれら樹脂の変性樹脂等が代表的なものとして挙げられる。なお、これらバインダー樹脂は、必要に応じて、各バインダー樹脂と共に通常に使用されている硬化剤を併用してもよい。
【００１０】
また、上記溶剤としては、通常、塗料やインクに使用されているものが特に制限なく利用可能であるが、具体的には、例えば、メタノール、エタノール、イソプロピルアルコール、シクロヘキサノール（アルコール系）；ヘキサン、オクタン、ノナン、デカン（パラフィン系）；イソヘキサン、イソオクタン、イソドデカン（イソパラフィン系）；イソプロピルエーテル、ｎ−ブチルエーテル、ジイソアミルエーテル（エーテル系）；メチルエチルケトン、ジイソブチルケトン（ケトン系）；酢酸メチル、酢酸エチル、ギ酸イソブチル（エステル系）；等の静置状態における表面張力が１７〜２７ｍＮ／ｍの溶剤が代表的なものとして挙げられ、これら溶剤は、二種以上の混合溶剤として使用してもよい。
【００１１】
また、これら溶剤に、通常、塗料やインクに使用されている、表面張力が１７〜２７ｍＮ／ｍの範囲外の溶剤を併用することも可能である。
【００１２】
本発明で使用する被覆剤は、こうような成分から構成され、ハジキや膜厚ムラが生じないようにするため、以下の特性を有する必要がある。
【００１３】
（１）被覆剤は、２０℃における粘度が１００ｍＰａ・ｓ以下、好ましくは６０ｍＰａ・ｓ以下であること。
【００１４】
なお、粘度が１００ｍＰａ・ｓを超えると、転写膜の膜厚制御が困難となる。
【００１５】
粘度は、回転粘度計（例えば、（株）トキメック製、Ｂ型粘度計）にて測定される。
【００１６】
（２）被覆剤は、静止状態における表面張力が２８ｍＮ／ｍ以下、好ましくは２２〜２６ｍＮ／ｍであること。
【００１７】
なお、表面張力が、２８ｍＮ／ｍを超えると薄膜、例えば、５μｍ以下の膜厚制御が困難となる。
【００１８】
（３）被覆剤の構成成分である溶剤として、静置状態における表面張力が１７〜２７ｍＮ／ｍ、好ましくは１８〜２６ｍＮ／ｍの溶剤を、全溶剤に対して５〜１００質量％、好ましくは１０〜９０質量％含有すること。
【００１９】
なお、表面張力が１７〜２７ｍＮ／ｍの溶剤が、５質量％未満の場合、被覆剤の表面張力の調整が困難となる。
【００２０】
表面張力は、Ｗｉｌｈｅｌｍｙ法（例えば、協和界面科学（株）製、表面張力計ＣＢＶＰ−Ａ型）にて測定される。
【００２１】
更に、好ましくは、以下の（４）、（５）及び（６）の条件を満たす被覆剤が好ましい。
【００２２】
（４）被覆剤の、転写される基材との静的接触角が３６°以下、より好ましくは３２°以下、更に好ましくは３０°以下であること。
【００２３】
なお、静的接触角が３６°を超えると、被覆剤の精密な印刷、塗装の制御が難しくなり、また、ハジキや膜厚ムラも生じ易くなる傾向にある。
【００２４】
静的接触角は、液滴法（例えば、協和界面科学（株）製、接触角計ＣＡ−Ｘ型）にて測定される。
【００２５】
（５）静置状態における表面張力が１７〜２７ｍＮ／ｍの溶剤が、パラフィン系溶剤、イソパラフィン系溶剤、アルコール系溶剤であること。
【００２６】
なお、溶剤として、パラフィン系溶剤、イソパラフィン系溶剤あるいはアルコール系溶剤を全く含まない場合、転写ロールがシリコーンゴム系の場合、転写ロールの溶解や膨潤が生じ易く、ロールを傷めるだけでなく、転写が不完全になったり膜厚ムラが生じ易くなる傾向にある。
【００２７】
（６）沸点１７５℃以上で、かつ、静置状態における表面張力２７．５ｍＮ／ｍ以上の溶剤が全溶剤に対して１５質量％未満であること。
【００２８】
なお、この溶剤が１５質量％以上となると、被覆剤の乾燥が遅くなるため、膜厚制御が困難となるので好ましくない。
【００２９】
本発明の転写方法は、以上説明した（１）〜（３）の条件、好ましくは（１）〜（６）の条件を満たす方法で実施することにより、ハジキや膜厚ムラのない転写膜が形成される。
【００３０】
なお、これら条件を満たすためには、実際に転写される基材を使用して、上記被覆剤のバインダー樹脂や溶剤等の構成成分の種類、量等を事前に調整し、被覆剤の上記特性を確認測定して決定すればよい。
【００３１】
なお、被覆剤中のバインダー樹脂や溶剤の量は、それらの種類や形成する膜厚等により任意に決定されるが、通常、バインダー樹脂５〜５０質量％、溶剤９５〜５０質量％が適当である。
【００３２】
転写方法としては、転写する目的や用途に応じて決定すればよく、例えば、ロールコーター法、ダイコーター法、ブレードコーター法、グラビアコート法、フローコーター法及びバーコート法等が代表的な方法として挙げられる。
【００３３】

The present invention relates to a method for transferring a coating material onto a substrate surface in a state in which repelling and unevenness in film thickness are unlikely to occur, and a coating material for transfer to a substrate.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various coating agents have been printed or painted on the surface of a substrate made of various materials such as plastic, paper, metal, wood, and inorganic materials for the purpose of imparting decoration, image, functionality, and the like. A transfer method is known as one of the printing and coating means.
[0003]
By the way, when transferring a coating material onto a sheet-like, film-like or plate-like base material surface, unevenness in film thickness and cissing often occur easily, and in order to solve the problem, the surface of the base material is usually treated with a specific surface treatment agent. This problem has been solved by pre-treatment or by blending various additives such as an antifoaming agent and a viscosity modifier with the coating agent. However, the method of treating the surface of a substrate with a surface treatment agent requires additional treatment steps and has a problem in terms of cost. Further, it is necessary to develop a surface treatment agent for each type of substrate, and the film There is a problem that thickness unevenness and repelling occur. In addition, the method of compounding additives and the like often causes the same problem unless the coating agent is compounded and designed according to the type of the base material. there were.

A transfer coating agent is provided.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The present inventors have conducted intensive studies to solve the above problems, and as a result, used a coating agent having a specific viscosity and surface tension as a transferred coating agent, and further containing a solvent having a specific surface tension. By doing so, they have found that the above-mentioned object can be achieved, and have reached the present invention.
[0008]
The coating agent used in the present invention contains a binder resin (in combination with a curing agent as necessary) and a solvent for dissolving or stably dispersing the binder resin as essential components. Dye pigments such as coloring pigments, extender pigments, dyes, etc. used in the ink; those containing various additives such as dispersants, viscosity modifiers, antioxidants, ultraviolet absorbers, antistatic agents, and curing accelerators. Consists of
[0009]
As the binder resin, those usually used for paints and inks can be used without any particular limitation.Specifically, for example, epoxy resin, polyester resin, acrylic resin, silicone resin, alkyd resin, Typical examples include urethane resins, fluororesins, and modified resins of these resins. In addition, as for these binder resins, you may use together the hardening | curing agent normally used with each binder resin.
[0010]
As the solvent, those usually used for paints and inks can be used without any particular limitation. Specifically, for example, methanol, ethanol, isopropyl alcohol, cyclohexanol (alcohol); hexane Octane, nonane, decane (paraffin type); isohexane, isooctane, isododecane (isoparaffin type); isopropyl ether, n-butyl ether, diisoamyl ether (ether type); methyl ethyl ketone, diisobutyl ketone (ketone type); methyl acetate, ethyl acetate , Isobutyl formate (ester type); and a solvent having a surface tension of 17 to 27 mN / m in a stationary state, and these solvents may be used as a mixed solvent of two or more kinds.
[0011]
It is also possible to use a solvent having a surface tension outside the range of 17 to 27 mN / m, which is usually used for paints and inks, together with these solvents.
[0012]
The coating agent used in the present invention is composed of such components and needs to have the following properties in order to prevent repelling and uneven film thickness.
[0013]
(1) The coating material has a viscosity at 20 ° C. of 100 mPa · s or less, preferably 60 mPa · s or less.
[0014]
If the viscosity exceeds 100 mPa · s, it becomes difficult to control the thickness of the transfer film.
[0015]
The viscosity is measured with a rotational viscometer (for example, a B-type viscometer manufactured by Tokimec Co., Ltd.).
[0016]
(2) The coating material has a surface tension in a stationary state of 28 mN / m or less, preferably 22 to 26 mN / m.
[0017]
When the surface tension exceeds 28 mN / m, it is difficult to control the thickness of a thin film, for example, 5 μm or less.
[0018]
(3) As a solvent which is a component of the coating agent, a solvent having a surface tension of 17 to 27 mN / m, preferably 18 to 26 mN / m in a stationary state is 5 to 100% by mass, preferably 5 to 100% by mass based on all the solvents. 10 to 90% by mass.
[0019]
If the solvent having a surface tension of 17 to 27 mN / m is less than 5% by mass, it becomes difficult to adjust the surface tension of the coating agent.
[0020]
The surface tension is measured by a Wilhelmy method (for example, surface tension meter CBVP-A, manufactured by Kyowa Interface Science Co., Ltd.).
[0021]
More preferably, a coating agent satisfying the following conditions (4), (5) and (6) is preferable.
[0022]
(4) The static contact angle of the coating material with the substrate to be transferred is 36 ° or less, more preferably 32 ° or less, further preferably 30 ° or less.
[0023]
If the static contact angle exceeds 36 °, precise control of printing and coating of the coating material becomes difficult, and repelling and film thickness unevenness tend to occur.
[0024]
The static contact angle is measured by a droplet method (for example, contact angle meter CA-X, manufactured by Kyowa Interface Science Co., Ltd.).
[0025]
(5) The solvent having a surface tension in a stationary state of 17 to 27 mN / m is a paraffin solvent, an isoparaffin solvent, or an alcohol solvent.
[0026]
When the solvent does not contain any paraffin-based solvent, isoparaffin-based solvent, or alcohol-based solvent, and when the transfer roll is a silicone rubber-based solvent, the transfer roll is liable to be dissolved or swelled. It tends to be incomplete or uneven in film thickness.
[0027]
(6) A solvent having a boiling point of 175 ° C. or more and a surface tension of 27.5 mN / m or more in a stationary state is less than 15% by mass based on all solvents.
[0028]
When the amount of the solvent is 15% by mass or more, drying of the coating agent is delayed, and it is difficult to control the film thickness.
[0029]
The transfer method of the present invention is implemented by a method that satisfies the conditions (1) to (3) described above, preferably the conditions (1) to (6), so that a transfer film free from repelling and film thickness unevenness can be obtained. It is formed.
[0030]
In order to satisfy these conditions, the type and amount of the components such as the binder resin and the solvent of the coating agent are adjusted in advance using the base material to be actually transferred, and the characteristics of the coating agent are adjusted. May be determined by confirming measurement.
[0031]
The amount of the binder resin and the solvent in the coating agent is arbitrarily determined depending on the kind and the thickness of the film to be formed, but usually 5 to 50% by mass of the binder resin and 95 to 50% by mass of the solvent are appropriate. is there.
[0032]
The transfer method may be determined according to the purpose and application of the transfer, for example, a roll coater method, a die coater method, a blade coater method, a gravure coat method, a flow coater method and a bar coat method as typical methods. No.
