Description

本発明は、電子機器の加飾フィルムおよびその製造方法に関する。   The present invention relates to a decorative film for an electronic device and a method for manufacturing the same.

従来、携帯電話,デジタルカメラ,テレビ,パソコン等の電子機器の表示部に用いられる加飾フィルムには、シルク印刷等で加飾フィルムの基板背面側に文字や画面装飾等の加飾を施す場合があるが、この場合フィルム基材の面より盛り上がる形で加飾層が形成されるため、基板における加飾が施されていない面と加飾層とで段差が生じてしまう。そのため、ガラス等の他の硬質な板体に光学両面テープを介して加飾フィルムを貼りつける場合、基板における加飾が施されていない面が光学両面テープに引っ張られ様に変形して加飾フィルムが歪んだ面形状となってしまい、透過性にムラが生じてしまう虞があった。   Conventionally, decorative films such as mobile phones, digital cameras, televisions, personal computers, etc. used for display parts of electronic devices are decorated with letters, screen decorations, etc. on the back side of the decorative film substrate by silk printing etc. However, in this case, since the decorative layer is formed so as to rise from the surface of the film base material, a step is generated between the surface of the substrate that is not decorated and the decorative layer. Therefore, when a decorative film is attached to another hard plate such as glass via an optical double-sided tape, the surface on the substrate that has not been decorated is deformed as if pulled by the optical double-sided tape. As a result, the film has a distorted surface shape, which may cause uneven transmission.

そこで、加飾が施されていない面および加飾層の上面に紫外線硬化樹脂を充填し、この硬化樹脂の上面に離型剤を塗布したセパレーターフィルムを被覆した状態で上下からローラーで挟圧した後、紫外線照射により紫外線硬化樹脂を硬化させることで加飾フィルムを製造する方法がある(例えば、特許文献1参照)。これによれば、加飾層とフィルム基材の背面を紫外線硬化樹脂内に埋没させて段差を解消するとともに、硬化樹脂がセパレーターフィルムにより平滑な面に均された状態で硬化できる。そして、この紫外線硬化樹脂の上面に透過性を有する光学両面テープを貼着することでガラス等の他の硬質な板体に貼り付け可能としている。   Therefore, the surface that has not been decorated and the upper surface of the decorative layer were filled with an ultraviolet curable resin, and the upper surface of the cured resin was covered with a separator film coated with a release agent, and pressed with rollers from above and below. Thereafter, there is a method of producing a decorative film by curing an ultraviolet curable resin by ultraviolet irradiation (see, for example, Patent Document 1). According to this, the decorative layer and the back surface of the film substrate are buried in the ultraviolet curable resin to eliminate the step, and the cured resin can be cured in a state of being smoothed by the separator film. And the optical double-sided tape which has permeability | transmittance is affixed on the upper surface of this ultraviolet curable resin, and it can be affixed on other hard boards, such as glass.

特開平2012−22281号公報(第7頁、第4図)Japanese Unexamined Patent Publication No. 2012-22281 (7th page, FIG. 4)

しかしながら、特許文献1の加飾フィルムにあっては、紫外線照射による樹脂の硬化後にセパレーターフィルムを剥離し、最後に紫外線硬化樹脂の上面に光学両面テープを貼り付ける態様であるため工数が多く、製造作業が煩雑であった。また、型材として利用したセパレーターフィルムを硬化後の紫外線硬化樹脂より剥がしやすくするためにセパレーターフィルムの表面には離型剤が塗布されているため、セパレーターフィルム剥離時に紫外線硬化樹脂上に離型剤が残存し、結果的に紫外線硬化樹脂と光学両面テープとの間に離型剤が介在することになり、完成した加飾フィルムにおいて光の透過性にムラが生じてしまう虞がある。   However, in the decorative film of Patent Document 1, since the separator film is peeled after the resin is cured by ultraviolet irradiation, and finally the optical double-sided tape is attached to the upper surface of the ultraviolet curable resin, the number of steps is large, and the manufacturing is performed. The work was complicated. In addition, a release agent is applied to the surface of the separator film in order to make it easier to peel off the separator film used as a mold material than the cured ultraviolet curable resin. As a result, a release agent is interposed between the ultraviolet curable resin and the optical double-sided tape, and there is a possibility that unevenness in light transmittance may occur in the completed decorative film.

本発明は、このような問題点に着目してなされたもので、光の透過性に優れる加飾フィルム、および簡便に光の透過性に優れる加飾フィルムを製造する方法を提供することを目的とする。   The present invention has been made paying attention to such problems, and an object of the present invention is to provide a decorative film excellent in light transmittance and a method for easily producing a decorative film excellent in light transmittance.

図1の符号1は、スマートフォンの表示部に用いられる加飾フィルムである。尚、本発明の加飾フィルムは、これに限らず携帯電話,デジタルカメラ,テレビ,パソコン等の電子機器の表示部に適用可能である。尚、ここでは説明しやすいように後述する加飾層3,紫外線硬化樹脂4,粘着層5およびセパレーター8を実際の厚みより厚く図示している。   The code | symbol 1 of FIG. 1 is a decorating film used for the display part of a smart phone. The decorative film of the present invention is not limited to this and can be applied to a display unit of an electronic device such as a mobile phone, a digital camera, a television, and a personal computer. For ease of explanation, the decorative layer 3, the ultraviolet curable resin 4, the adhesive layer 5 and the separator 8 which will be described later are shown thicker than the actual thickness.

加飾フィルム1は、そのフィルム基材2における背面2aに画面表示枠となる加飾層3が形成され、また加飾層3の背面には後に詳述する紫外線硬化樹脂4および粘着テープ層5が貼着されて構成されるようになっており、さらに粘着層5の粘着力により電子機器の表示部を構成するガラス等の硬質の板体に対して貼着可能となっている。フィルム基材2は、透明のポリエステルフィルムやポリカーボネート,アクリル,ガラスまたはこれらの素材を積層させたもの等で形成される。   The decorative film 1 is provided with a decorative layer 3 serving as a screen display frame on the back surface 2a of the film substrate 2, and an ultraviolet curable resin 4 and an adhesive tape layer 5 described in detail later on the back surface of the decorative layer 3. Can be adhered to a hard plate such as glass constituting the display unit of the electronic device by the adhesive force of the adhesive layer 5. The film substrate 2 is formed of a transparent polyester film, polycarbonate, acrylic, glass, or a laminate of these materials.

粘着層5はアクリル系のゲル状の樹脂等で形成されて表裏両面に粘着面5a,5bを有しており、これら粘着面5a,5b両面がセパレーターにより被覆されており、このうち粘着面5a側のセパレーター8を剥離して加飾層3の上面に貼着されるようになっている(図5参照)。   The pressure-sensitive adhesive layer 5 is formed of an acrylic gel-like resin or the like and has pressure-sensitive adhesive surfaces 5a and 5b on both front and back surfaces. Both the pressure-sensitive adhesive surfaces 5a and 5b are covered with a separator, and of these, the pressure-sensitive adhesive surface 5a. The separator 8 on the side is peeled off and attached to the upper surface of the decorative layer 3 (see FIG. 5).

さらに加飾層3には、電子機器の仕様に応じて図1に示されるような抜き穴9aおよび画面表示用の開口9bが形成されており、このうち抜き穴9aはスマートフォンに内蔵されたカメラ機能におけるフラッシュや照度センサー等の透過性を必要とする機能を使用可能とするために設けられている。   Further, the decoration layer 3 is formed with a hole 9a and a screen display opening 9b as shown in FIG. 1 according to the specifications of the electronic device, and the hole 9a is a camera built in the smartphone. It is provided in order to make it possible to use a function that requires transparency such as a flash or an illuminance sensor.

加飾フィルム1は、全体像は特段図示しない製造ライン内の各工程を経ることでフィルム基材2の背面2aに対し前述した加飾層3、紫外線硬化樹脂4、粘着層5およびセパレーター8が順に積層されて製造されるようになっている。また、一度に複数の加飾フィルム1を製造するために、大判のフィルム基材2(図2参照)を製造ラインに配置されたローラーによって搬送し、全工程の終了後に所定の形状に裁断されるようになっている。   The decorative film 1 has the decorative layer 3, the ultraviolet curable resin 4, the adhesive layer 5, and the separator 8 described above with respect to the back surface 2 a of the film base 2 by undergoing each process in a production line (not shown) as a whole. It is manufactured by being laminated in order. Moreover, in order to manufacture the several decorating film 1 at once, the large format film base material 2 (refer FIG. 2) is conveyed with the roller arrange | positioned at a manufacturing line, and is cut | judged to the predetermined shape after completion | finish of all the processes. It has become so.

製造ライン内における各工程について図3から図8を用いて説明する。まず、大判のフィルム基材2が製造ラインにセットされ、ローラー10,10,…の回転で図3に示される加飾層3の形成工程まで搬送される。   Each process in the production line will be described with reference to FIGS. First, the large-sized film base 2 is set on the production line, and is conveyed to the forming process of the decoration layer 3 shown in FIG. 3 by the rotation of the rollers 10, 10,.

加飾層3の形成工程は、所定の加飾層3の形状に形成された凸部6aを複数備えたローラー状の印刷版6を備えており、これらの凸部6a,6a,…にはそれぞれインクが塗布されている。そして、ローラー10によって搬送されるフィルム基材2に対して印刷版6が回転しながら押し付けられることで大判のフィルム基材2上に複数の加飾層3,3,…が一度に形成される。   The step of forming the decorative layer 3 includes a roller-shaped printing plate 6 including a plurality of convex portions 6a formed in the shape of the predetermined decorative layer 3, and these convex portions 6a, 6a,. Each is coated with ink. Then, the printing plate 6 is pressed against the film substrate 2 conveyed by the roller 10 while rotating, whereby a plurality of decorative layers 3, 3,... Are formed on the large film substrate 2 at a time. .

なお、利用される電子機器の仕様によるが、この加飾層3は主に表示部周辺に配置される配線やネジ等が露見しないようにする用途で表示部の周りに配置される場合が多いため、透過性を持たないように形成されるのが一般的である。尚、加飾層3は、フィルム基材2の周部に配置される加飾以外に、ロゴ等の文字を施す場合にも用いられる。   Depending on the specifications of the electronic device used, the decorative layer 3 is often arranged around the display unit for the purpose of preventing the wiring, screws, and the like arranged mainly around the display unit from being exposed. For this reason, it is generally formed so as not to have transparency. In addition, the decoration layer 3 is used also when giving characters, such as a logo, in addition to the decoration arrange | positioned at the peripheral part of the film base material 2. FIG.

また、製造工程では特に図示しないが加飾層3はインクの塗布を2回行うことで2段に積層されて塗布されており、1段目の加飾層3aが2段目の加飾層3bより大きく形成されている(図8(a)参照)。そのため2段目の加飾層3a、すなわち加飾フィルム1の背面側に位置する加飾層3の内縁が1段目の加飾層3aに隠れて外方より視認されず美観に優れる。   Although not specifically shown in the manufacturing process, the decorative layer 3 is applied in two layers by applying the ink twice, and the first decorative layer 3a is the second decorative layer. It is larger than 3b (see FIG. 8A). Therefore, the 2nd step of the decorative layer 3a, that is, the inner edge of the decorative layer 3 located on the back side of the decorative film 1 is hidden behind the first step of the decorative layer 3a and is not visually recognized from the outside, which is excellent in aesthetics.

次に、加飾層3が形成されたフィルム基材2は紫外線硬化樹脂4の塗布工程まで搬送される。図4に示されるように紫外線硬化樹脂4の塗布工程は、加飾層3の外縁形状と略同形に形成された凸部7aを複数備えたローラー状の印刷版7を備えており、これら凸部7a,7a,…にはそれぞれ紫外線硬化樹脂4が塗布されている。そして、ローラー10によって搬送されるフィルム基材2および加飾そう3に対して印刷版7が回転しながら押し付けられることで、複数の加飾層3,3,…の上に紫外線硬化樹脂4,4,…の層が一度に形成される。   Next, the film substrate 2 on which the decorative layer 3 is formed is conveyed to the application step of the ultraviolet curable resin 4. As shown in FIG. 4, the coating process of the ultraviolet curable resin 4 includes a roller-shaped printing plate 7 including a plurality of convex portions 7 a formed substantially in the same shape as the outer edge shape of the decorative layer 3. The ultraviolet curable resin 4 is applied to each of the portions 7a, 7a,. Then, the printing plate 7 is pressed against the film substrate 2 and the decoration 3 that is conveyed by the roller 10 while rotating, so that the ultraviolet curable resin 4 is placed on the plurality of decoration layers 3, 3. Four layers are formed at a time.

尚、このとき印刷版7における紫外線硬化樹脂4,4,…を塗布する凸部7a,7a,…は、加飾層3,3,…の外縁形状と略同形にそれぞれベタ塗りする形状となっており、図8(b)に示されるようにフィルム基材2の背面2aおよび加飾層3の上面3cおよび3dに紫外線硬化樹脂4が充填されて、当該フィルム基材の背面2aと加飾層3とが紫外線硬化樹脂4内に埋没する。また、このとき紫外線硬化樹脂4は前記加飾層3における前記抜き穴9aおよび画面表示用の開口9b内にも入り込んで充填される。   At this time, the convex portions 7a, 7a,... On which the ultraviolet curable resins 4, 4,... On the printing plate 7 are applied are solidly applied in the same shape as the outer edge shape of the decorative layers 3, 3,. 8B, the back surface 2a of the film substrate 2 and the upper surfaces 3c and 3d of the decorative layer 3 are filled with the ultraviolet curable resin 4, and the back surface 2a of the film substrate and the decoration The layer 3 is buried in the ultraviolet curable resin 4. At this time, the ultraviolet curable resin 4 also enters and fills the punched holes 9a and the screen display openings 9b in the decorative layer 3.

続いてフィルム基材2は、前述した紫外線硬化樹脂4の充填の完了後に、紫外線硬化樹脂4の上面に粘着層5を形成する工程に移される。図5および図8(c)に示されるように、粘着層5は透過性を有するゲル状の素材で形成されており、表裏に粘着面5a,5bを有している。また、粘着面5bを被覆するセパレーター8は透過性を有するとともに粘着テープより変形し難い材質のフィルムからなる。尚、セパレーター8は少なくとも紫外線を透過する素材であれば他の光線を透過しない材質であってもよい。   Subsequently, the film substrate 2 is moved to the step of forming the adhesive layer 5 on the upper surface of the ultraviolet curable resin 4 after completion of the filling of the ultraviolet curable resin 4 described above. As shown in FIGS. 5 and 8C, the adhesive layer 5 is formed of a gel-like material having permeability, and has adhesive surfaces 5a and 5b on the front and back sides. Further, the separator 8 that covers the adhesive surface 5b is made of a film that is permeable and hardly deformed from the adhesive tape. The separator 8 may be made of a material that does not transmit other rays as long as it is a material that transmits at least ultraviolet rays.

紫外線硬化樹脂4の上面4aに粘着層5を形成する工程は、加圧手段である加圧ローラー11を有しており、粘着層5は粘着面5aからセパレーター(図示せず)が剥離された状態で加圧ローラー11に一部巻きつけられるようにして粘着面5aを紫外線硬化樹脂4の上面4aに所定の力で押し付けられるようになっている。なお、粘着層5およびセパレーター8は大判のフィルム基材2の面全体を被覆するように貼り付けられる。   The step of forming the pressure-sensitive adhesive layer 5 on the upper surface 4a of the ultraviolet curable resin 4 includes a pressure roller 11 as a pressure means, and the pressure-sensitive adhesive layer 5 has a separator (not shown) peeled off from the pressure-sensitive adhesive surface 5a. The pressure-sensitive adhesive surface 5 a is pressed against the upper surface 4 a of the ultraviolet curable resin 4 with a predetermined force so as to be partially wound around the pressure roller 11. The adhesive layer 5 and the separator 8 are affixed so as to cover the entire surface of the large film base 2.

上記したように、粘着層5に比べ変形し難いセパレーター8が粘着層5を介して紫外線硬化樹脂4に押し付けられるため、紫外線硬化樹脂4の上面形状がセパレーター8および粘着層5の表面5aの形状に均されて図8(d)に示されるような平らな面に成形される。   As described above, since the separator 8 which is not easily deformed compared to the adhesive layer 5 is pressed against the ultraviolet curable resin 4 through the adhesive layer 5, the upper surface shape of the ultraviolet curable resin 4 is the shape of the surface 8 a of the separator 8 and the adhesive layer 5. And formed into a flat surface as shown in FIG.

なお、電子顕微鏡等で観察した場合、粘着層5の粘着面5aの表面に図6に示されるような微細な凹凸形状が確認できるが、硬化以前の紫外線硬化樹脂4は粘着層5よりも軟性であるため、これらの凹凸形状に対して紫外線硬化樹脂4が入り込んで粘着テープ5と紫外線硬化樹脂4との間に隙間が生じない。   In addition, when observed with an electron microscope or the like, a fine uneven shape as shown in FIG. 6 can be confirmed on the surface of the adhesive surface 5 a of the adhesive layer 5, but the ultraviolet curable resin 4 before curing is softer than the adhesive layer 5. Therefore, the ultraviolet curable resin 4 enters the concave and convex shapes, and no gap is generated between the adhesive tape 5 and the ultraviolet curable resin 4.

なお、このとき紫外線硬化樹脂4および粘着層5は、セパレーター8とフィルム基材2とに挟まれた状態で前記加圧ローラー11と搬送ローラー10とによって挟圧されるようになっており、さらに加圧ローラー11と搬送ローラー10とが所定の離間距離に設定されているため、紫外線硬化樹脂4および粘着層5の厚みが型くずれすること無く所定の厚みに成形される。   At this time, the ultraviolet curable resin 4 and the adhesive layer 5 are sandwiched between the pressure roller 11 and the transport roller 10 while being sandwiched between the separator 8 and the film substrate 2. Since the pressure roller 11 and the transport roller 10 are set to a predetermined separation distance, the thickness of the ultraviolet curable resin 4 and the adhesive layer 5 is molded to a predetermined thickness without being out of shape.

続いて図7に示されるフィルム基材2は紫外線照射工程に搬送される。紫外線照射工程は、上方に紫外線照射装置20を設けており、この紫外線照射装置20からセパレーター8,粘着層5,紫外線硬化樹脂4に対して紫外線を照射し、紫外線硬化樹脂4を硬化させる。このとき、セパレーター8および粘着層5が透過性を有していることから紫外線が紫外線硬化樹脂4全面に到達するため、紫外線硬化樹脂4を万遍なく硬化させることが可能である。尚、紫外線硬化樹脂4は少なくともその硬化後において透過性を有するようになっていることは言うまでもない。   Subsequently, the film substrate 2 shown in FIG. 7 is conveyed to the ultraviolet irradiation process. In the ultraviolet irradiation process, an ultraviolet irradiation device 20 is provided on the upper side, and ultraviolet rays are irradiated from the ultraviolet irradiation device 20 to the separator 8, the adhesive layer 5, and the ultraviolet curable resin 4 to cure the ultraviolet curable resin 4. At this time, since the separator 8 and the adhesive layer 5 are transmissive, the ultraviolet rays reach the entire surface of the ultraviolet curable resin 4, so that the ultraviolet curable resin 4 can be uniformly cured. Needless to say, the ultraviolet curable resin 4 has transparency at least after being cured.

そして紫外線照射工程の完了後はフィルム基材2の裁断工程(図示せず)に移り、この裁断工程におけるカッター装置等により大判のフィルム基材2とフィルム基材2の面全体を覆うように貼り付けられた粘着層5およびセパレーター8が、所定の大きさおよび裁断位置で切り抜かれて加飾フィルム1が完成する。このとき前記フレキソ印刷時に所定範囲よりはみ出した加飾層3ならびに加圧ローラー11による挟圧で加飾層3より外方にはみ出した紫外線硬化樹脂4は、この裁断工程時に同時に除去される。   Then, after completion of the ultraviolet irradiation process, the film substrate 2 is cut to a cutting process (not shown), and the large film substrate 2 and the entire film substrate 2 are covered with a cutter device or the like in the cutting process. The attached adhesive layer 5 and separator 8 are cut out at a predetermined size and cutting position, and the decorative film 1 is completed. At this time, the decorative layer 3 that protrudes from the predetermined range during the flexographic printing and the ultraviolet curable resin 4 that protrudes outward from the decorative layer 3 due to the pressure between the pressure rollers 11 are simultaneously removed during the cutting step.

なお、紫外線硬化樹脂4はむしろ加飾層3より外方に若干はみ出す程度の量を塗布されてもよく、この場合、前記紫外線照射による紫外線硬化樹脂の硬化後における樹脂の肉痩せ等にも対応できる他、上述したように加飾層3からはみ出した分は裁断工程時に除去可能であるため、塗布する樹脂の計量において極端に高い精度を有した装置を必要とせず設備コストを下げることができる。   The UV curable resin 4 may be applied in an amount that slightly protrudes outward from the decorative layer 3, and in this case, the resin can be thinned after the UV curable resin is cured by UV irradiation. In addition, since the portion protruding from the decorative layer 3 can be removed during the cutting process as described above, the equipment cost can be reduced without requiring an apparatus having extremely high accuracy in measuring the resin to be applied. .

以上説明したように本発明の加飾フィルムは、背面2aに加飾層3を施されたフィルム基材2に対し、フィルム基材2の背面2aおよび加飾層3の上面3cおよび3dに紫外線硬化樹脂4を充填して当該フィルム基材2の背面2aと加飾層3とを紫外線硬化樹脂4内に埋没させることで段差を解消することができ、さらに当該紫外線硬化樹脂4の上面を、図示しないガラス等の板体の上面に貼着させる透過性の粘着層5を押し付けて紫外線硬化樹脂4の上面を平滑に形成できる。また、加飾フィルム1を板体に貼着させるための粘着層5を紫外線硬化樹脂4の型材として利用したことから、製造工程を大幅に簡略化して製造効率を高めることができる。また従来のように紫外線硬化樹脂4と粘着層5との間に離型剤が介在することがないため、光の透過性に優れた加飾フィルム1を製造できることになる。   As described above, the decorative film of the present invention has ultraviolet rays on the back surface 2a of the film base material 2 and the upper surfaces 3c and 3d of the decorative layer 3 with respect to the film base material 2 with the decorative layer 3 applied to the back surface 2a. Steps can be eliminated by filling the curable resin 4 and burying the back surface 2a of the film base 2 and the decorative layer 3 in the ultraviolet curable resin 4, and further, the upper surface of the ultraviolet curable resin 4 is The upper surface of the ultraviolet curable resin 4 can be smoothly formed by pressing the permeable adhesive layer 5 to be adhered to the upper surface of a plate body such as glass (not shown). Moreover, since the adhesive layer 5 for attaching the decorative film 1 to the plate is used as a mold material of the ultraviolet curable resin 4, the manufacturing process can be greatly simplified and the manufacturing efficiency can be increased. Moreover, since a mold release agent does not intervene between the ultraviolet curable resin 4 and the adhesion layer 5 like the past, the decorating film 1 excellent in the light transmittance can be manufactured.

また、加飾フィルム1をガラス等の板体に貼り付ける際に使用される粘着層5およびセパレーター8が、紫外線硬化樹脂4の硬化前の型材としての利用も兼ねるため、従来のような別途型材を用意しての紫外線硬化樹脂の成形および成形後における型材の剥離工程が省略でき、製造工程を大幅に簡略化して製造効率を高めることができる。さらに、紫外線硬化樹脂と粘着層5との間には離型剤などが不要であることから、完成後の加飾フィルム1に生じる光の透過性のムラを防止できる。さらに、セパレーター8を介して所定の加圧ローラー11により粘着層5が紫外線硬化樹脂4に対して押し付けられるため、安定して、かつ均等に紫外線硬化樹脂4の上面が加圧されることになり、加飾フィルム1の平滑度を向上できることになる。   In addition, since the adhesive layer 5 and the separator 8 used when the decorative film 1 is attached to a plate body such as glass can also be used as a mold material before curing of the ultraviolet curable resin 4, a separate mold material as in the past is used. The molding process of the UV curable resin and the mold material peeling process after molding can be omitted, and the manufacturing process can be greatly simplified to increase the manufacturing efficiency. Furthermore, since a mold release agent or the like is not required between the ultraviolet curable resin and the adhesive layer 5, unevenness in light transmission that occurs in the decorative film 1 after completion can be prevented. Furthermore, since the adhesive layer 5 is pressed against the ultraviolet curable resin 4 by the predetermined pressure roller 11 through the separator 8, the upper surface of the ultraviolet curable resin 4 is pressed stably and evenly. The smoothness of the decorative film 1 can be improved.

紫外線硬化樹脂4は、その上面に加圧ローラー11により粘着層5を直接押し付けられた後に紫外線照射による硬化が行われることから、図6に示されるように硬化前は液体状に近い紫外線硬化樹脂4が粘着層5の粘着面5a表面の微細な凹凸形状に入り込み、紫外線硬化樹脂4の表面4aが粘着面5a表面に沿った形状で硬化される。そのため粘着層5と紫外線硬化樹脂4との間に隙間が生じず、完成後の加飾フィルム1における光の透過性にムラが発生しないばかりか、粘着層5と紫外線硬化樹脂4両者の当接面積の広さはもとより、粘着層5と紫外線硬化樹脂4との物理的凹凸表面結合により両者の結合力が高く耐久性に優れた加飾フィルム1が提供される。また、加圧ローラー11により粘着層5が紫外線硬化樹脂4に対して押し付けに利用されたセパレーター8を残しているため、加飾フィルム1をガラス等の硬質な板体に貼着する際にこのセパレーター8を剥離して使用することができる。   Since the ultraviolet curable resin 4 is cured by ultraviolet irradiation after the pressure-sensitive adhesive layer 5 is directly pressed onto the upper surface of the ultraviolet curable resin 4, the ultraviolet curable resin is almost liquid before curing as shown in FIG. 6. 4 enters the fine uneven shape on the surface of the adhesive surface 5a of the adhesive layer 5, and the surface 4a of the ultraviolet curable resin 4 is cured in a shape along the surface of the adhesive surface 5a. Therefore, there is no gap between the pressure-sensitive adhesive layer 5 and the ultraviolet curable resin 4, and there is no unevenness in the light transmission in the decorative film 1 after completion. The decorative film 1 having a high bonding strength and excellent durability due to the physical uneven surface bonding between the adhesive layer 5 and the ultraviolet curable resin 4 as well as the area is provided. Further, since the pressure-sensitive roller 11 leaves the separator 8 used for pressing the ultraviolet curable resin 4 with the pressure-sensitive adhesive layer 11, the decorative film 1 is adhered to a hard plate such as glass. The separator 8 can be peeled off and used.

以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。   Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

例えば、前記実施例では、フィルム基材2の背面2aと加飾層3の上面3c,3d上に充填される樹脂に紫外線硬化樹脂を使用しているが、紫外線により硬化されるものにかぎらず、例えばEB硬化樹脂等のラドキュア樹脂や熱硬化樹脂等であってよく、この場合粘着層5の貼着後に紫外線照射に代えて電子線照射や加熱処理等のそれぞれの工程を設けて樹脂を硬化させる。   For example, in the said Example, although the ultraviolet curable resin is used for resin with which the back surface 2a of the film base material 2 and the upper surfaces 3c and 3d of the decoration layer 3 are filled, it is not restricted to what is hardened | cured by an ultraviolet-ray. For example, it may be a radicure resin such as an EB curable resin, a thermosetting resin, or the like. In this case, the resin is cured by providing respective steps such as electron beam irradiation and heat treatment instead of ultraviolet irradiation after the adhesion layer 5 is adhered. Let

また、予め粘着層の粘着面5a上に紫外線硬化樹脂4を所定の厚みで形成しておき、これらをフィルム基材2および加飾層3上に同時に貼着させることで、製造工程を簡略化してもよい。   In addition, the ultraviolet curable resin 4 is formed in advance with a predetermined thickness on the adhesive surface 5a of the adhesive layer, and these are simultaneously stuck on the film substrate 2 and the decorative layer 3, thereby simplifying the manufacturing process. May be.

また、加飾層3に紫外線透過性を有する素材を用いて、紫外線の照射を下面側すなわちフィルム基材2側から行うようにしてもよい。   Moreover, you may make it perform irradiation of an ultraviolet-ray from the lower surface side, ie, the film base material 2 side, using the raw material which has an ultraviolet-ray transmittance for the decoration layer 3. FIG.

また、前記実施例において紫外線硬化樹脂4は、加圧ローラー11による加圧工程により粘着層5が押し付けられた後に紫外線照射工程が行われる態様で説明されているが、これに限らず、たとえば前述したようにフィルム基材2側から紫外線の照射を行うなどして、加圧工程と同時に紫外線照射工程を行うようにしてもよい。   Moreover, although the ultraviolet curable resin 4 is demonstrated in the said Example in the aspect by which an ultraviolet irradiation process is performed after the adhesion layer 5 is pressed by the pressurization process by the pressure roller 11, it is not restricted to this, For example, the above-mentioned As described above, the ultraviolet ray irradiation step may be performed simultaneously with the pressurizing step by irradiating the ultraviolet ray from the film substrate 2 side.

また、加飾フィルム1はガラス等の板体に貼着させた状態で出荷されてもよく、たとえば、紫外線硬化樹脂4の上面に直接印刷版を押し付けて粘着層5を形成し、粘着層の粘着面5bにガラス等の板体を貼り合わせたのちに加圧ローラー11による加圧工程および紫外線照射工程を行う。これによればセパレーター8を省略できることから材料費を削減可能である。   In addition, the decorative film 1 may be shipped in a state of being adhered to a plate body such as glass. For example, the printing plate is pressed directly on the upper surface of the ultraviolet curable resin 4 to form the adhesive layer 5, After a plate body such as glass is bonded to the adhesive surface 5b, a pressurizing step and an ultraviolet irradiation step with the pressure roller 11 are performed. According to this, since the separator 8 can be omitted, the material cost can be reduced.

また、加飾層3及び紫外線硬化樹脂4の形成は、前記実施例のようなローラーを利用したフレキソ印刷等に限らず、例えばスクリーン印刷や熱転写やインクジェット印刷等によって行われてもよい。   Moreover, the formation of the decoration layer 3 and the ultraviolet curable resin 4 is not limited to flexographic printing using a roller as in the above embodiment, and may be performed by, for example, screen printing, thermal transfer, ink jet printing, or the like.

また、セパレーター8および粘着層5を紫外線硬化樹脂4に押し付ける加圧手段は加圧ローラー11と搬送ローラー10による挟圧に限らず、水圧や空圧,プレス装置等を用いて加圧を行うようにしてもよい。   The pressing means for pressing the separator 8 and the adhesive layer 5 against the ultraviolet curable resin 4 is not limited to the pressure between the pressure roller 11 and the transport roller 10, and the pressure is applied using water pressure, air pressure, a press device, or the like. It may be.
