Description

【０００１】
【発明の属する技術分野】
本発明は、ワーク表面に転写模様を施す転写加飾方法及びそれに使用する加飾用転写フィルムに関し、特に、ワークの曲面部分を加飾するのに好適なものである。
【０００２】
【従来の技術】
ワークの曲面部分に加飾を施す一般的な方法として、水圧転写法が知られている。
これは、グラビアインキなどで任意の模様を印刷した水溶性フィルムを水に浮かべ、その水溶性フィルムを溶解させてインキ模様を水面に形成し、ワークの加飾面を水没させることにより、水面に浮かんだインキ模様を水圧により転写させるものである。
【０００３】
これによれば、水面に浮いている模様が水圧により加飾面全体に回り込んで付着するので、加飾面が曲面に形成されていても、その形状を気にすることなく加飾を施すことができる。
【０００４】
【発明が解決しようとする課題】
しかしながら、水圧転写を行なう場合、水溶性フィルムを水に浮かべて溶解させるようにしているので、転写するまでに時間がかかると、水溶性フィルムの溶解が進んで膨潤し過ぎてしまい、模様を形成するグラビアドットが引き伸ばされて柄呆けを生ずるという問題があった。
【０００５】
また、水溶性フィルムは膨潤すると非常によく伸び、加飾面の形状変化に追従できるという利点があるが、模様の柄もその形状変化に応じて伸び縮みして柄が乱れやすいので、水圧転写の模様は、柄の乱れが目立たないような木目などの抽象絵柄に限定され、柄の乱れが目立つ幾何学的な模様は水圧転写には向かないという問題があった。
【０００６】
さらに、水溶性フィルムを水に浮かべて模様を転写するので、フィルムに対してワークを位置決めすることは極めて困難であり、加飾面の特定の位置に特定の絵柄を印刷させることができない。
【０００７】
さらにまた、多少位置ずれしても加飾面全体に確実に模様を転写できるように、加飾面に比して十分大きな転写フィルムを用いているのが現状であり、その分、大量の転写フィルムが無駄に捨てられているという問題があった。
【０００８】
そこで本発明は、グラビアドットが引き伸ばされて柄呆けを起こしたり、柄の乱れが目立つ幾何学的な模様でも柄の乱れを生ずることなく、さらに、転写フィルムを節約すると共に、模様の絵柄に対してワークを容易に位置決めして転写できるようにすることを技術的課題としている。
【０００９】
【課題を解決するための手段】
この課題を解決するために、請求項１に係る転写加飾方法は、水溶性フィルムの表面に疎水性インキで任意の模様を印刷した印刷層が形成されると共にその上層に接着層が形成されて成る加飾用転写フィルムを、その接着層を露出させた状態で、ワークの加飾面の形状に応じて変形自在な微粘着性弾性基材上に仮止めし、前記微粘着性弾性基材を押し当てることにより転写フィルムをワークの加飾面に接着させ、前記加飾面を覆う水溶性フィルムを水洗除去した後、当該加飾面に転写された模様を覆う透明コーティング皮膜を形成することを特徴とする。
【００１０】
本発明方法によれば、加飾用転写フィルムが接着層を露出させて微粘着性弾性基材に仮止めされているので、この弾性基材をワークの加飾面に押し当てることにより、転写フィルムが弾性基材から剥がれて加飾面に接着される。
【００１１】
そして、転写フィルムを構成する水溶性フィルムを水洗除去すると、その模様が加飾面に残って転写形成され、当該加飾面に透明コーティング皮膜を形成して加飾を終了する。
【００１２】
このとき転写フィルムは微粘着性弾性基材に仮止めされているので、加湿されて溶解が進むようなことがあっても、印刷された模様のグラビアドットが広がって模様が柄呆けを起こす程大きく引き伸ばされることがない。
【００１３】
また、微粘着性弾性基材を押し当てていくことにより、転写フィルムは加飾面に加圧接着され、局部的に極端に大きく引き伸ばされることもないので、幾何学的な模様を転写しても柄の乱れが少ない。
【００１４】
さらに、ワークの加飾面に対して転写フィルムの位置を確認しながら貼り付けていくことができるので、転写フィルムを加飾面の形状に応じた大きさに形成しても失敗することが少なく、特定の模様が特定の場所に位置するように転写可能である。
【００１５】
請求項２の発明方法のように、微粘着接着剤でキャリアシートに水溶性フィルムを仮止めし、その表面に疎水性インキで任意の模様を印刷し、その上層に接着剤を塗布して接着層を形成し、その接着層に剥離紙を貼付して加飾用転写フィルムを形成すれば、接着層も水溶性フィルムも覆われているので、転写フィルムをロール状に丸めたり重ねたりして保管することができ、運搬時にも傷つくことがなく、その取扱いがさらに容易になる。
【００１６】
請求項３の発明方法のように、ワークの加飾面に接着剤を塗布して接着層を形成し、当該加飾面に前記微粘着性弾性基材を押し当てながら転写フィルムを接着させるようにすれば、従来の水圧転写に使用していた転写フィルムに加工を施すことなくそのまま使用することができる。
【００１７】
請求項４の発明方法のように、接着層を構成する接着剤に、印刷層の疎水性インキを活性化させる活性剤を含有しておけば、インキがより確実に加飾面に転写される。
【００１８】
請求項５の発明方法のように、加飾用転写フィルムの印刷層にインキの溶剤などを塗布して疎水性インキを活性化させると、活性化されたインキの粘着力で前記転写フィルムをワークの加飾面に接着させることができ、接着剤は不要となる。
【００１９】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて具体的に説明する。
図１は本発明に係る転写加飾方法を示す説明図、図２は本発明に係る転写加飾フィルムを示す図、図３及び図４は本発明に係る他の転写加飾方法を示す説明図である。
【００２０】
図１に示す転写加飾方法は、加飾転写フィルム１が仮止めされた微粘着性弾性基材２をワークＷの加飾面３に押し当てて、前記加飾転写フィルム１に印刷された模様を転写させるようにしている。
【００２１】
加飾転写フィルム１は、図２に示すように、水溶性フィルム４の表面に、グラビアインキ等の疎水性インキで任意の模様を印刷した印刷層５が形成されると共に、その上層に接着層６が形成されてなり、この接着層６に剥離紙７が貼付されて形成されている。
【００２２】
そして、この加飾転写フィルム１の形成方法としては、紙に微粘着接着剤９を塗布した微粘着性キャリアシート８に水溶性フィルム４を仮止めし、その表面に疎水性インキで任意の模様を印刷することにより印刷層５を形成し、その上から前記微粘着接着剤９より粘着力の強い接着剤を塗布して形成し、この接着層６に剥離紙７を貼付する（図１（ａ）参照）。
【００２３】
このようにすれば、水溶性シート４がキャリアシート８に覆われ、接着層６が剥離紙７に覆われるので、長尺に形成した転写フィルム１をロール状に丸めて保管したり、シートに形成した転写フィルム１を重ねて保管することもでき、その際に水溶性シート４に傷がつくこともない。
【００２４】
なお、このようにして形成した転写フィルム１以外に、市販の水圧転写用転写フィルムを利用して、その印刷層の上に接着剤を塗布して接着層６を形成しても同様である。
【００２５】
次いで、加飾用転写フィルム１をワークＷの加飾面３の形状に応じて裁断した後、剥離紙７側を上向きにして、水溶性フィルム４を微粘着性弾性基材２に貼り付ける（図１（ｂ）参照）。
【００２６】
この微粘着性弾性基材２は、ワークＷの加飾面３の形状に応じて変形自在な柔軟性を有し、且つ、表面に接着層６の接着剤よりも粘着力の弱い微粘着接着剤１０が塗布されたウレタンゴムシートやニトリルゴムシートで形成されている。
【００２７】
そして、微粘着性弾性基材２に加飾転写フィルム１を仮止めした後、剥離紙７を剥がすと接着層６が露出する。
この状態で、必要に応じて加飾転写フィルム１を水又はアルコールなどで加湿し、弾性基材２をワークＷの加飾面３に押し当てると、転写フィルム１の接着層６が加飾面３に加圧接着される（図１（ｃ）参照）。
【００２８】
なお、この場合に、弾性基材２をワークＷの加飾面３に押し付ける場合に限らず、ワークＷを弾性基材２に押し付けることにより、その反作用として、微粘着性弾性基材２をワークＷの加飾面３に押し当てるようにしてもよい。
【００２９】
このとき、弾性基材２はワークＷの加飾面３の形状に応じて自在に変形するので、加飾転写フィルム１を加飾面３に沿わせて接着していくことができる（図１（ｄ）参照）。
また、加飾転写フィルム１は、微粘着接着剤１０により微粘着性弾性基材２に仮止めされているので、転写フィルム１が加湿されて溶解が進んでも、印刷層５の模様のグラビアドットが広がったり模様が柄呆けを起こすことはない。
【００３０】
さらに、弾性基材２を押し当てていくことにより、転写フィルム１は加飾面３に加圧接着されるので、局部的に極端に大きく引き伸ばされることがなく、幾何学的な模様を転写しても柄の乱れが目立つことがない。
【００３１】
さらにまた、ワークＷの加飾面３に対して転写フィルム１の位置を確認しながら貼り付けていくことができるので、位置決めが容易で、転写フィルム１を加飾面３の形状に応じた大きさに形成しても失敗することがほとんどなく、特定の模様が特定の場所に位置するように転写することもできる。
【００３２】
なお、加飾転写フィルム１の接着層６に用いる接着剤中に、印刷層５のグラビアインキを活性化させる活性剤（例えばインキ用溶剤）を含有しておけば、印刷層５のインキが接着層６の接着剤とよく馴染むので、接着剤と共にワークＷの加飾面３により確実に転写される。
【００３３】
また、加飾転写フィルム１を水又はアルコールで加湿して、水溶性フィルム４が延伸可能な状態にした後、ワークＷの加飾面３に貼り付けるようにすれば、水溶性フィルム４も自在に伸びるので、より作業性に優れる。
【００３４】
そして、加飾転写フィルム１を加飾面３に接着させた後は、通常の水圧転写と同様に、ワークＷをウォーターバス１１に入れて水溶性フィルム４を完全に溶解して除去し（図１（ｅ）参照）、その印刷層５に形成された模様を加飾面３に転写形成させ、これを乾燥させて加飾面３にクリア塗料などでコーティング皮膜１２を形成する（図１（ｆ）参照）。
【００３５】
なお、コーティング皮膜に用いる塗料は、無色透明、着色透明に限らず、有色塗料であってもコーティング皮膜１２を形成した状態で、転写した模様が視認できる程度の光透過性を有していれば良い。
【００３６】
図３は、本発明方法の他の実施形態を示し、本例では、加飾転写フィルム２１として従来の水圧転写フィルムを使用し、転写フィルム２１に接着層を形成するのではなく、ワークＷの加飾面３に接着層２２を形成する。
【００３７】
すなわち、加飾転写フィルム２１は、水溶性フィルム４の表面にグラビアインキで任意の模様を印刷した印刷層５が形成されて成り、この加飾用転写フィルム２１の印刷層５を露出させて、微粘着性弾性基材２に仮止めされる。
【００３８】
そして、ワークＷの加飾面３に接着剤を塗布して接着層２２を形成し、当該加飾面３に弾性基材２を押し当てながら転写フィルム１を接着させる。その後は、図１に示す方法と同様に、ウォーターバス１１で水溶性フィルム４を溶解させ、最後に、クリア塗料でコーティング皮膜１２を形成する。
【００３９】
なお、この場合も、接着層２２に用いる接着剤中に、印刷層５のグラビアインキを活性化させる活性剤（例えばインキ用溶剤）を含有させておけば、印刷層５のインキが接着層２２の接着剤とよく馴染んで、ワークＷの加飾面３に確実に転写される。
【００４０】
図４は、本発明方法のさらに他の実施形態を示し、本例は、加飾転写フィルム２１及びワークＷの加飾面３の双方に接着層を形成することなく、加飾転写フィルム２１の印刷層５をワークＷの加飾面３に転写できるようにしたものである。
【００４１】
まず、図３に示す方法と同様に、水溶性フィルム４の表面にグラビアインキで任意の模様を印刷した印刷層５を形成して成る加飾転写フィルム２１を、その印刷層５を上向にして微粘着性弾性基材２に仮止めしておく。
次いで、加飾用転写フィルム２１にグラビアインキの溶剤を塗布してそのインキを活性化させると、印刷層５は活性化されたインキで粘着性を呈する（図４（ａ）参照）。
【００４２】
この状態で、弾性基材２をワークＷの加飾面３に押し当てると（図４（ｂ）参照）、インキの粘着力で転写フィルム２１が加飾面３に接着すると同時に、印刷層５の模様が加飾面に転写される。
したがって、接着層を形成しないで済み、接着剤は不要となる。
その後は、図１に示す方法と同様に、ウォーターバス１１で水溶性フィルム４を溶解させ、最後に、クリア塗料でコーティング皮膜１２を形成すればよい。
【００４３】
【発明の効果】
以上述べたように、本発明方法によれば、転写フィルムは微粘着性弾性基材に仮止めされているので、加湿されて溶解が進むようなことがあっても、印刷された模様のグラビアドットが広がったり模様が柄呆けを起こすことはなく、印刷模様と同程度のきめの細かい模様を転写することができるという優れた効果を有する。
【００４４】
また、微粘着性弾性基材を押し当てていくことにより、転写フィルムは加飾面に加圧接着され、局部的に極端に大きく引き伸ばされることもないので、幾何学的な模様を柄の乱れがほとんどない状態に転写することができるという効果がある。
【００４５】
さらに、ワークの加飾面に対して転写フィルムの位置を確認しながら貼り付けていくことができるので、位置決めが容易で、転写フィルムを加飾面の形状に応じた大きさに形成しても失敗することが少なく、転写フィルムを必要最小限の大きさに形成してフィルムの節約を図ることができ、特定の模様が特定の場所に位置するように転写することができるという大変優れた効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a transfer decoration method for applying a transfer pattern to a workpiece surface and a transfer film for decoration used therefor, and is particularly suitable for decorating a curved surface portion of a workpiece.
[0002]
[Prior art]
A hydraulic transfer method is known as a general method for decorating a curved surface portion of a workpiece.
This is because a water-soluble film printed with a gravure ink or other pattern is floated on water, the water-soluble film is dissolved to form an ink pattern on the water surface, and the decorative surface of the workpiece is submerged. The floating ink pattern is transferred by water pressure.
[0003]
According to this, since the pattern floating on the water surface wraps around and adheres to the entire decoration surface due to water pressure, even if the decoration surface is formed in a curved surface, decoration is performed without worrying about the shape. be able to.
[0004]
[Problems to be solved by the invention]
However, when water pressure transfer is performed, the water-soluble film floats and dissolves in water, so if it takes time to transfer, the water-soluble film dissolves and swells too much, forming a pattern. There was a problem that the gravure dots to be stretched were stretched, resulting in pattern blurring.
[0005]
In addition, water-soluble film has the advantage that it swells very well when swollen and can follow the shape change of the decorative surface, but the pattern of the pattern expands and contracts according to the shape change, and the pattern is easily disturbed. The pattern was limited to abstract patterns such as wood grain where the pattern disturbance was inconspicuous, and there was a problem that the geometric pattern where the pattern disturbance was conspicuous was not suitable for hydraulic transfer.
[0006]
Furthermore, since the pattern is transferred by floating the water-soluble film in water, it is extremely difficult to position the workpiece with respect to the film, and a specific pattern cannot be printed at a specific position on the decorative surface.
[0007]
Furthermore, in order to ensure that the pattern can be transferred to the entire decorative surface even if the position is slightly shifted, the transfer film is sufficiently large compared to the decorative surface. There was a problem that the film was wasted.
[0008]
Therefore, the present invention does not cause pattern distortion even when a gravure dot is stretched to cause a pattern blur or a geometric pattern in which the pattern disturbance is conspicuous. Therefore, a technical problem is to enable easy positioning and transfer of a workpiece.
[0009]
[Means for Solving the Problems]
In order to solve this problem, in the transfer decoration method according to claim 1, a printing layer in which an arbitrary pattern is printed with a hydrophobic ink is formed on the surface of a water-soluble film, and an adhesive layer is formed thereon. The decorative transfer film is temporarily fixed on a slightly adhesive elastic substrate that can be deformed according to the shape of the decorative surface of the workpiece with the adhesive layer exposed, and the slightly adhesive elastic base The transfer film is adhered to the decorative surface of the workpiece by pressing the material, and after removing the water-soluble film covering the decorative surface with water, a transparent coating film is formed to cover the pattern transferred to the decorative surface. It is characterized by that.
[0010]
According to the method of the present invention, since the decorative transfer film is temporarily fixed to the slightly sticky elastic base material with the adhesive layer exposed, the transfer can be performed by pressing the elastic base material against the decorative surface of the workpiece. The film is peeled off from the elastic substrate and adhered to the decorative surface.
[0011]
Then, when the water-soluble film constituting the transfer film is removed by washing, the pattern remains on the decorative surface to be transferred and formed, and a transparent coating film is formed on the decorative surface to complete the decoration.
[0012]
At this time, since the transfer film is temporarily fixed to the slightly adhesive elastic base material, even if it is humidified and the dissolution proceeds, the gravure dot of the printed pattern spreads and the pattern causes a pattern blur. It is not greatly stretched.
[0013]
Also, by pressing the slightly sticky elastic base material, the transfer film is pressure-bonded to the decorative surface and is not stretched extremely large locally. There is little disorder of the handle.
[0014]
In addition, since the transfer film can be attached to the decorative surface of the workpiece while checking the position of the transfer film, it is less likely to fail even if the transfer film is formed in a size according to the shape of the decorative surface. It is possible to transfer such that a specific pattern is located at a specific place.
[0015]
As in the method of the invention of claim 2, a water-soluble film is temporarily fixed on a carrier sheet with a slightly adhesive adhesive, an arbitrary pattern is printed on the surface with a hydrophobic ink, and an adhesive is applied to the upper layer for adhesion. If a transfer film for decoration is formed by attaching a release paper to the adhesive layer to form a decorative transfer film, both the adhesive layer and the water-soluble film are covered. It can be stored and will not be damaged during transportation, making it easier to handle.
[0016]
As in the method of the invention of claim 3, an adhesive is applied to the decorative surface of the work to form an adhesive layer, and the transfer film is adhered while pressing the slightly sticky elastic substrate to the decorative surface. In this case, the transfer film used for conventional hydraulic transfer can be used as it is without being processed.
[0017]
If the adhesive constituting the adhesive layer contains an activator that activates the hydrophobic ink of the printed layer as in the invention method of claim 4, the ink is more reliably transferred to the decorative surface. .
[0018]
When the hydrophobic ink is activated by applying an ink solvent or the like to the printing layer of the decorative transfer film as in the method of the invention of claim 5, the transfer film is worked with the adhesive force of the activated ink. It can be made to adhere to the decorative surface, and no adhesive is required.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is an explanatory view showing a transfer decoration method according to the present invention, FIG. 2 is a view showing a transfer decoration film according to the present invention, and FIGS. 3 and 4 are illustrations showing another transfer decoration method according to the present invention. FIG.
[0020]
The transfer decoration method shown in FIG. 1 was printed on the decorative transfer film 1 by pressing the slightly adhesive elastic base material 2 temporarily attached to the decorative transfer film 1 against the decorative surface 3 of the workpiece W. The pattern is transferred.
[0021]
As shown in FIG. 2, the decorative transfer film 1 has a printing layer 5 on which an arbitrary pattern is printed on a surface of a water-soluble film 4 with a hydrophobic ink such as gravure ink, and an adhesive layer on the upper layer. 6 is formed, and a release paper 7 is pasted on the adhesive layer 6.
[0022]
And as a formation method of this decorative transfer film 1, the water-soluble film 4 is temporarily fixed to the slightly adhesive carrier sheet 8 which apply | coated the slightly adhesive adhesive 9 to paper, and arbitrary patterns are made with hydrophobic ink on the surface. Is formed by applying an adhesive having a higher adhesive strength than the slightly adhesive 9 and a release paper 7 is attached to the adhesive layer 6 (FIG. 1 ( a)).
[0023]
In this way, since the water-soluble sheet 4 is covered with the carrier sheet 8 and the adhesive layer 6 is covered with the release paper 7, the long-formed transfer film 1 is rolled into a roll shape and stored. The formed transfer film 1 can be stacked and stored, and the water-soluble sheet 4 is not damaged at that time.
[0024]
Note that, in addition to the transfer film 1 formed in this way, a commercially available transfer film for hydraulic transfer is used to form an adhesive layer 6 by applying an adhesive on the printed layer.
[0025]
Next, after the decorative transfer film 1 is cut according to the shape of the decorative surface 3 of the work W, the water-soluble film 4 is attached to the slightly adhesive elastic substrate 2 with the release paper 7 side facing upward ( (Refer FIG.1 (b)).
[0026]
This slightly sticky elastic base material 2 has a flexible flexibility that can be deformed according to the shape of the decorative surface 3 of the workpiece W, and has a sticky adhesion that is weaker than the adhesive of the adhesive layer 6 on the surface. It is formed of a urethane rubber sheet or a nitrile rubber sheet to which the agent 10 is applied.
[0027]
And after temporarily fixing the decorative transfer film 1 to the slightly adhesive elastic base material 2, if the release paper 7 is peeled, the contact bonding layer 6 will be exposed.
In this state, when the decorative transfer film 1 is humidified with water or alcohol as necessary, and the elastic substrate 2 is pressed against the decorative surface 3 of the workpiece W, the adhesive layer 6 of the transfer film 1 becomes the decorative surface. 3 (see FIG. 1C).
[0028]
In this case, not only the case where the elastic base material 2 is pressed against the decorative surface 3 of the workpiece W, but also by pressing the work W against the elastic base material 2, the slightly adhesive elastic base material 2 is attached to the work as a reaction. You may make it press on the decorating surface 3 of W.
[0029]
At this time, since the elastic base material 2 is freely deformed according to the shape of the decorative surface 3 of the workpiece W, the decorative transfer film 1 can be adhered along the decorative surface 3 (FIG. 1). (See (d)).
Further, since the decorative transfer film 1 is temporarily fixed to the slightly adhesive elastic substrate 2 by the slightly adhesive 10, even if the transfer film 1 is humidified and the dissolution proceeds, the gravure dots in the pattern of the printing layer 5 The pattern does not spread and the pattern does not cause a sensation.
[0030]
Furthermore, the transfer film 1 is pressure-bonded to the decorative surface 3 by pressing the elastic substrate 2, so that the geometric pattern is transferred without being extremely stretched locally. However, the disorder of the pattern does not stand out.
[0031]
Furthermore, since the position of the transfer film 1 can be affixed to the decorative surface 3 of the work W while confirming the position, positioning is easy and the transfer film 1 has a size corresponding to the shape of the decorative surface 3. Even if it is formed, it hardly fails, and it can be transferred so that a specific pattern is located at a specific place.
[0032]
In addition, if the activator (for example, solvent for ink) which activates the gravure ink of the printing layer 5 is contained in the adhesive used for the adhesive layer 6 of the decorative transfer film 1, the ink of the printing layer 5 adheres. Since it is well compatible with the adhesive of the layer 6, it is reliably transferred together with the adhesive by the decorative surface 3 of the workpiece W.
[0033]
Further, if the decorative transfer film 1 is humidified with water or alcohol so that the water-soluble film 4 can be stretched, and then attached to the decorative surface 3 of the workpiece W, the water-soluble film 4 is also free. Therefore, it is more workable.
[0034]
After adhering the decorative transfer film 1 to the decorative surface 3, the workpiece W is placed in the water bath 11 and the water-soluble film 4 is completely dissolved and removed, as in normal water pressure transfer (see FIG. 1 (e)), the pattern formed on the printed layer 5 is transferred and formed on the decorative surface 3, and is dried to form the coating film 12 on the decorative surface 3 with a clear paint or the like (FIG. 1 ( f)).
[0035]
In addition, the coating material used for the coating film is not limited to colorless and transparent and colored and transparent, but even if it is a colored coating material, the coating film 12 is formed as long as it has a light transmittance that allows the transferred pattern to be visually recognized. good.
[0036]
FIG. 3 shows another embodiment of the method of the present invention. In this example, a conventional hydraulic transfer film is used as the decorative transfer film 21, and an adhesive layer is not formed on the transfer film 21. An adhesive layer 22 is formed on the decorative surface 3.
[0037]
That is, the decorative transfer film 21 is formed by forming a printing layer 5 on the surface of the water-soluble film 4 by printing an arbitrary pattern with gravure ink, exposing the printing layer 5 of the decorative transfer film 21, It is temporarily fixed to the slightly adhesive elastic base material 2.
[0038]
Then, an adhesive is applied to the decorative surface 3 of the workpiece W to form the adhesive layer 22, and the transfer film 1 is adhered while pressing the elastic substrate 2 against the decorative surface 3. After that, similarly to the method shown in FIG. 1, the water-soluble film 4 is dissolved by the water bath 11, and finally the coating film 12 is formed by the clear paint.
[0039]
Also in this case, if the activator (for example, ink solvent) that activates the gravure ink of the printing layer 5 is contained in the adhesive used for the adhesive layer 22, the ink of the printing layer 5 becomes the adhesive layer 22. The adhesive is well transferred to the decorative surface 3 of the workpiece W.
[0040]
FIG. 4 shows still another embodiment of the method of the present invention. In this example, the decorative transfer film 21 is formed without forming an adhesive layer on both the decorative transfer film 21 and the decorative surface 3 of the workpiece W. The printing layer 5 can be transferred to the decorative surface 3 of the workpiece W.
[0041]
First, similarly to the method shown in FIG. 3, a decorative transfer film 21 formed by forming a printing layer 5 in which an arbitrary pattern is printed with gravure ink on the surface of the water-soluble film 4, with the printing layer 5 facing upward. And temporarily fixed to the slightly adhesive elastic base material 2.
Next, when a gravure ink solvent is applied to the decorative transfer film 21 and the ink is activated, the printing layer 5 exhibits adhesiveness with the activated ink (see FIG. 4A).
[0042]
In this state, when the elastic substrate 2 is pressed against the decorative surface 3 of the workpiece W (see FIG. 4B), the transfer film 21 adheres to the decorative surface 3 by the adhesive force of the ink, and at the same time, the printing layer 5 The pattern is transferred to the decorative surface.
Therefore, it is not necessary to form an adhesive layer, and no adhesive is required.
Thereafter, similarly to the method shown in FIG. 1, the water-soluble film 4 is dissolved by the water bath 11, and finally the coating film 12 is formed by the clear paint.
[0043]
【The invention's effect】
As described above, according to the method of the present invention, the transfer film is temporarily fixed to the slightly adhesive elastic base material. Dots do not spread and the pattern does not cause pattern blurring, and it has an excellent effect that a fine pattern as fine as the printed pattern can be transferred.
[0044]
In addition, by pressing the slightly adhesive elastic base material, the transfer film is pressure-bonded to the decorative surface, and it is not stretched extremely greatly locally. There is an effect that the image can be transferred in a state where there is almost no.
[0045]
Furthermore, since the transfer film can be attached to the decorative surface of the workpiece while confirming the position, positioning is easy and the transfer film can be formed in a size corresponding to the shape of the decorative surface. It has a very good effect of being able to transfer a specific pattern at a specific location with few mistakes, making the transfer film as small as possible and saving the film. Have
