Description

本発明は、機能性部材用工程材料、およびこれを用いた機能性部材の処理方法に関する。   The present invention relates to a process material for a functional member and a method for treating a functional member using the same.

従来より、工業用用途において機能性部材を用いる際に、例えば機能性部材の厚みが薄い、コシがない、搬送性が悪い、耐熱性が低い、耐薬品性が低い、傷つきやすい等といった理由により、前記機能性部材に工程用部材を貼合して用いる場合がある（特許文献１、特許文献２、特許文献３参照）。このような場合、一般的には図１のように、基材４上に粘着層３を有する工程用部材６の粘着層３を有する面を機能性部材１に貼り合せ、所望の産業的処理を施した後、機能性部材１から工程用部材６を剥離することにより、機能性部材１が処理されている。   Conventionally, when a functional member is used in an industrial application, for example, the thickness of the functional member is thin, no stiffness, poor transportability, low heat resistance, low chemical resistance, and easily damaged In some cases, a process member is bonded to the functional member for use (see Patent Document 1, Patent Document 2, and Patent Document 3). In such a case, generally, as shown in FIG. 1, the surface having the adhesive layer 3 of the process member 6 having the adhesive layer 3 on the substrate 4 is bonded to the functional member 1, and desired industrial treatment is performed. After performing, the functional member 1 is processed by peeling the process member 6 from the functional member 1.

ところが、このような工程で処理されたものは、機能性部材から工程用部材を剥離する際に、粘着層がきれいに剥がれず機能性部材に粘着層が残ってしまうという問題が生じた。また、工程用部材の粘着層を有する面を機能性部材に貼り合せた後に、施した産業的処理やその後の環境（温度、湿度、圧力、時間など）により粘着層の接着力が向上してしまい、工程用部材を剥離する際の剥離強度が高くなり生産性が低下するといった問題も生じた。また、このような問題が生じないように、施す産業的処理やその後の環境に制限を加えなければならない場合もあった。   However, what was processed by such a process had a problem that when the process member was peeled from the functional member, the pressure-sensitive adhesive layer was not peeled off and the pressure-sensitive adhesive layer remained on the functional member. In addition, after bonding the surface of the process member with the adhesive layer to the functional member, the adhesive strength of the adhesive layer is improved by the applied industrial treatment and the subsequent environment (temperature, humidity, pressure, time, etc.) Therefore, there also arises a problem that the peel strength at the time of peeling off the process member becomes high and the productivity is lowered. Moreover, in order to prevent such a problem from occurring, it may be necessary to limit the industrial treatment to be performed and the subsequent environment.

また、機能性部材から剥離された工程用部材についても、粘着層表面に粘着性を有しているため、その後の取り扱い性が悪いという問題も生じている。   Further, the process member peeled from the functional member also has a problem that the subsequent handleability is poor because it has adhesiveness on the surface of the adhesive layer.

まず、第１の工程用部材５について説明する。第１の工程用部材５は機能性部材１上に剥離層２を有するものである。本発明でいう機能性部材１とは、所望の機能を有する部材のことであり、所望の産業的処理を施すための主となる部材のことである。このような機能性部材１としては、種々のものがあげられるため特に限定されるものではないが、例えば、紙、布帛、プラスチック、ガラス等のシート状や板状のもの（基材１１）に、所望の機能層１２を設けたもの（図４、図５）や、基材１１自体に所望の機能性を有するもの（図６）などがあげられる。   First, the first process member 5 will be described.

基材１１自体に所望の機能性を有するものとしては、上述した紙、布帛、プラスチック、ガラスや、これらに所望の機能を付与するために、例えば、光拡散剤、光反射剤、界面活性剤、顔料、染料等の種々の材料を混入させたものなどがあげられる。   Examples of the base 11 having the desired functionality include the above-described paper, fabric, plastic, glass, and the like, for example, a light diffusing agent, a light reflecting agent, and a surfactant in order to impart a desired function thereto. And various materials such as pigments and dyes.

このような機能を有する機能性部材１としては、例えば、液晶バックライト用光学フィルム、プリント配線基板用フィルム、各種出力機用記録フィルム、各種工業用光学フィルムなどがあげられる。   Examples of the functional member 1 having such a function include an optical film for a liquid crystal backlight, a film for a printed wiring board, a recording film for various output machines, and various industrial optical films.

また機能性部材１としては、例えば、プリント配線基板、電子部品などのように、立体的な形状を有するものであってもよい（図示せず）。   Moreover, as the functional member 1, you may have a three-dimensional shape (not shown) like a printed wiring board, an electronic component, etc., for example.

次に、剥離層２について説明する。剥離層２は前記機能性部材１上に設けられてなるものである。図２の場合は、剥離層２は機能性部材１の一方の面に設けられている。また剥離層２は後述する第２の工程用部材６の粘着層３と共に機能性部材１から剥離されて用いられるものである。よって、工程用部材部分６２が剥離される際の剥離強度は、機能性部材１と剥離層２との接着性に依存するものであり、粘着層３の接着力は、粘着層３と剥離層２との接着性が剥離層２と機能性部材１との接着性よりも大きければよい。したがって、後述する産業的処理の影響やその後の環境（温度、湿度、圧力、時間など）によって、粘着層３の接着力が向上してしまったとしても、工程用部材部分６２を剥離する際の剥離強度は左右されず、安定した生産性を維持することができる。また、粘着層３の接着力の向上による剥離強度の向上等の問題が生じないため、施す産業的処理やその後の環境に制限を加える必要がなく、自由度の高いものとすることができる。   Next, the release layer 2 will be described. The release layer 2 is provided on the functional member 1. In the case of FIG. 2, the release layer 2 is provided on one surface of the functional member 1. The release layer 2 is used by being peeled from the functional member 1 together with the adhesive layer 3 of the second process member 6 described later. Therefore, the peeling strength when the process member portion 62 is peeled depends on the adhesiveness between the functional member 1 and the peeling layer 2, and the adhesive force of the pressure-sensitive adhesive layer 3 is the pressure-sensitive adhesive layer 3 and the peeling layer. It is only necessary that the adhesion between the release layer 2 and the functional member 1 is greater than that between the release layer 2 and the functional member 1. Therefore, even when the adhesive force of the pressure-sensitive adhesive layer 3 is improved due to the influence of an industrial process described later and the subsequent environment (temperature, humidity, pressure, time, etc.), the process member portion 62 is peeled off. The peel strength is not affected, and stable productivity can be maintained. Moreover, since problems such as an improvement in peel strength due to an improvement in the adhesive strength of the pressure-sensitive adhesive layer 3 do not occur, there is no need to limit the industrial treatment to be applied and the subsequent environment, and the degree of freedom can be increased.

以上のような剥離層２は、上述の機能性部材１との接着性の低いものがよく、皮膜性を有するものが好ましい。剥離層２が皮膜性を有することにより、機能性部材１に剥離層２が残ることなく円滑に剥離することができる。特に機能性部材１が凹凸を有するものや、立体的な形状を有するものである場合には、剥離層２と粘着層３の密着しづらい箇所があった場合でも、機能性部材１に剥離層２が残ることなく円滑に剥離することができる。   The peeling layer 2 as described above is preferably one having low adhesion to the above-described functional member 1 and preferably having a film property. When the release layer 2 has a film property, the release layer 2 can be smoothly peeled without leaving the functional member 1. In particular, when the functional member 1 is uneven or has a three-dimensional shape, even if there is a place where the peeling layer 2 and the adhesive layer 3 are difficult to adhere, the functional member 1 has a peeling layer. 2 can be smoothly peeled without remaining.

また、剥離層２は、ＪＩＳ−Ｚ０２３７：２０００における傾斜式ボールタックの値が、２以下であることが好ましい。   Moreover, it is preferable that the peeling layer 2 has the value of the inclination type ball tack in JIS-Z0237: 2000 of 2 or less.

このような剥離層２の材料としては、用いられる機能性部材１の材料等によって異なってくるため一概にいえないが、ガラス転移温度が３０℃以上、好ましくは５０℃以上の合成樹脂が好ましく、例えば、基材１１がポリエステルの場合には、皮膜性に優れている点でアクリル、ウレタン、アミド、アルキッド、セルロース、ポリビニルアルコール、およびその変性物（ポリビニルブチラール、ポリビニルアセタール等）が好ましく、なかでも基材１１（ポリエステル）との剥離強度をポリビニルアルコール基の組成比により容易に制御できるという観点から、ポリビニルアルコール、およびその変性物がより好ましい。   The material of the release layer 2 varies depending on the material of the functional member 1 to be used, but cannot be generally described. However, a synthetic resin having a glass transition temperature of 30 ° C. or higher, preferably 50 ° C. or higher is preferable. For example, when the base material 11 is polyester, acrylic, urethane, amide, alkyd, cellulose, polyvinyl alcohol, and modified products thereof (polyvinyl butyral, polyvinyl acetal, etc.) are preferable because of excellent film properties. From the viewpoint that the peel strength with respect to the substrate 11 (polyester) can be easily controlled by the composition ratio of the polyvinyl alcohol group, polyvinyl alcohol and a modified product thereof are more preferable.

また、このような剥離層２には本発明の目的を阻害しない範囲であれば、顔料、離型剤、紫外線吸収剤、帯電防止剤、難燃剤、防カビ剤、防錆剤、光安定剤、酸化防止剤、可塑剤、レベリング剤、流動調整剤、消泡剤、分散剤、着色剤、硬化剤等の添加剤を使用してもよい。   In addition, the release layer 2 has a pigment, a release agent, an ultraviolet absorber, an antistatic agent, a flame retardant, an antifungal agent, a rust preventive agent, and a light stabilizer as long as the object of the present invention is not impaired. Additives such as antioxidants, plasticizers, leveling agents, flow regulators, antifoaming agents, dispersants, colorants, and curing agents may be used.

さらにこのような剥離層２には、選択する材料に応じて、種々の機能を付与しても構わない。例えば、剥離層２の材料として、ウレタン、アクリル、セルロース、塩化ビニル／酢酸ビニル共重合体、ポリビニルアルコール、およびその変性物等を用いる場合には、インクジェット出力適正を持たせることができる。   Furthermore, such a release layer 2 may be provided with various functions depending on the material selected. For example, when urethane, acrylic, cellulose, vinyl chloride / vinyl acetate copolymer, polyvinyl alcohol, a modified product thereof, or the like is used as the material of the release layer 2, ink jet output suitability can be imparted.

剥離層２の厚みは、特に限定されるものではないが、剥離時の皮膜性、第１の工程用部材５とした時の取り扱い性や、経済性という観点から、下限として１μｍ以上、好ましくは３μｍ以上とし、上限として１００μｍ以下、好ましくは５０μｍ以下とする。   The thickness of the release layer 2 is not particularly limited, but the lower limit is 1 μm or more, preferably from the viewpoint of film properties at the time of release, handleability when used as the first process member 5, and economy. 3 μm or more, and the upper limit is 100 μm or less, preferably 50 μm or less.

このような第１の工程用部材５は、上述した機能性部材１上に、上述した樹脂、および必要に応じて加えた添加剤を希釈溶剤によって混合して剥離層２用塗布液を調整し、従来公知のコーティング方法、例えば、バーコーター、ダイコーター、ブレードコーター、スピンコーター、ロールコーター、グラビアコーター、フローコーター、スプレー、スクリーン印刷等によって、塗布、乾燥し、必要により硬化させて剥離層２を形成して得ることができる。図３の第１の工程用部材５は、上記と同様にして機能性部材１の一方の面に剥離層２を形成し、もう一方の面にも同様にして剥離層２を形成することにより得ることができる。   Such a first process member 5 is prepared by mixing the above-described resin and the additive added as necessary with the diluent on the above-described functional member 1 to prepare a coating solution for the release layer 2. The release layer 2 is coated, dried, and cured as necessary by a conventionally known coating method such as bar coater, die coater, blade coater, spin coater, roll coater, gravure coater, flow coater, spray, screen printing, etc. Can be obtained. The first process member 5 in FIG. 3 is formed by forming the release layer 2 on one surface of the functional member 1 in the same manner as described above and forming the release layer 2 on the other surface in the same manner. Obtainable.

次に第２の工程用部材６について説明する。第２の工程用部材６は基材４の一方の面に粘着層３を有するものである。第２の工程用部材６は、上述の機能性部材１に所望の産業的処理を施すために用いられ、前記処理を施した後、上述の剥離層２と共に機能性部材１から剥離されるものである。   Next, the second process member 6 will be described. The second process member 6 has the adhesive layer 3 on one surface of the substrate 4. The second process member 6 is used to perform a desired industrial treatment on the functional member 1 described above, and is peeled from the functional member 1 together with the release layer 2 after the treatment. It is.

ここで、所望の産業的処理とは、特に限定されるものではなく、機能性部材１の種類や用途に応じた種々の処理を総じて称したものである。このような産業的処理としては、例えば、加熱処理、加湿処理、加圧処理、紫外線照射処理、赤外線照射処理、遠紫外線照射処理、プラズマ処理、コロナ放電処理、アルカリ処理、サンドブラスト処理、研磨処理、薬品処理、ダイシング処理、エンボス加工、打ち抜き加工、出力機による印刷、他の機能層の積層など種々の処理をあげることができる。また、本発明においては、例えば機能性部材１の輸送や保存をする際に、汚れや傷などから守るため第２の工程用部材６を用いるというような場合も、産業的処理として含むものである。   Here, the desired industrial treatment is not particularly limited, and collectively refers to various treatments according to the type and application of the functional member 1. As such industrial treatment, for example, heat treatment, humidification treatment, pressure treatment, ultraviolet irradiation treatment, infrared irradiation treatment, far ultraviolet irradiation treatment, plasma treatment, corona discharge treatment, alkali treatment, sandblast treatment, polishing treatment, Various treatments such as chemical treatment, dicing treatment, embossing, punching, printing with an output machine, and lamination of other functional layers can be exemplified. Further, in the present invention, for example, when the functional member 1 is transported or stored, the case where the second process member 6 is used to protect it from dirt or scratches is included as an industrial treatment.

Then, the functional member was processed. In addition, the value of the inclined ball tack (JIS-Z0237: 2000) in the adhesive layer was 7.

１．機能性部材の処理（インクジェット出力機による印刷）
（Ａ）インクジェット用フィルムのインク受容層を有していない方の面と、工程用部材の粘着層とを貼合したものを作製した。次に、（Ｂ）所望の産業的処理として、実施例１と同様にしてインク受容層を有する面に印刷を施した。次に、（Ｃ）インクジェット用フィルムから工程用部材（粘着層、および基材）を剥離することにより、機能性部材に施した処理が完了した。その結果、（Ｃ）の貼合後、インクジェット用フィルムから工程用部材（粘着層、および基材）を剥離したときの剥離強度（ＪＩＳ−Ｚ０２３７：２０００）は、１２Ｎ／２５ｍｍであった。 1. Processing of functional materials (printing by inkjet output machine)
(A) What stuck the surface which does not have the ink receiving layer of the film for inkjets, and the adhesion layer of the member for a process was produced. Next, (B) As a desired industrial treatment, printing was performed on the surface having the ink receiving layer in the same manner as in Example 1. Next, (C) the process applied to the functional member was completed by peeling the process member (the adhesive layer and the substrate) from the inkjet film. As a result, the peeling strength (JIS-Z0237: 2000) when peeling the process member (adhesion layer and base material) from the inkjet film after bonding (C) was 12 N / 25 mm.

［比較例２］
機能性部材として実施例２と同様の光拡散フィルムを用い、前記光拡散フィルム上に剥離層を設けなかった以外は実施例２と同様にして機能性部材用工程材料を２つ作製し、機能性部材の処理を行った。 [Comparative Example 2]
Two functional member process materials were prepared in the same manner as in Example 2 except that the same light diffusing film as in Example 2 was used as the functional member, and no release layer was provided on the light diffusing film. The sex member was processed.

１．機能性部材の処理（型抜機による打ち抜き加工）
上記機能性部材用工程材料を用いて、（Ａ）所望の産業的処理として、型抜機により機能性部材用工程材料の光拡散層を有していない方の面から、粘着層、ポリエステルフィルム（基材）を残すように半抜きし、必要箇所以外の光拡散フィルムを剥離することにより打ち抜き加工を施した（２つとも）。（Ｂ）その後、（Ａ）の状態の機能性部材用工程材料のうちの１つについては、６０℃の環境下に４８時間放置した。次にこれらの光拡散フィルム（機能性部材）から粘着層、および基材を剥離し、機能性部材に施した処理が完了した。その結果、６０℃の環境下に４８時間放置しなかった方の光拡散フィルムから粘着層、および基材を剥離したときの剥離強度（ＪＩＳ−Ｚ０２３７：２０００）は、２０Ｎ／２５ｍｍであり、６０℃の環境下に４８時間放置した方の剥離強度は、３０Ｎ／２５ｍｍ以上となり、光拡散フィルムとの接着性が向上してしまい剥離した際に基材ごと光拡散層に残ってしまう箇所もありきれいに剥離できないものとなった。また、６０℃の環境下に４８時間放置しなかった方の剥離後の粘着層における傾斜式ボールタックの値（ＪＩＳ−Ｚ０２３７：２０００）は５であった。 1. Processing of functional materials (Punching with a die cutting machine)
Using the above functional material process material, (A) As a desired industrial treatment, from the side having no light diffusion layer of the functional material process material by a die cutting machine, an adhesive layer, a polyester film ( Punching was performed by removing the light diffusion film except for the necessary portion and removing the half of the substrate so as to leave the substrate. (B) Thereafter, one of the functional member process materials in the state of (A) was left in an environment of 60 ° C. for 48 hours. Next, the adhesive layer and the substrate were peeled from these light diffusion films (functional members), and the treatment applied to the functional members was completed. As a result, the peel strength (JIS-Z0237: 2000) when the pressure-sensitive adhesive layer and the substrate were peeled from the light diffusion film that had not been left for 48 hours in an environment of 60 ° C. was 20 N / 25 mm, and 60 The peel strength when left for 48 hours in an environment of 0 ° C. is 30 N / 25 mm or more, and the adhesion to the light diffusing film is improved, and there are places where the entire substrate remains in the light diffusing layer when peeled off. It became a thing which cannot be exfoliated neatly. Further, the value of the tilted ball tack (JIS-Z0237: 2000) in the pressure-sensitive adhesive layer after peeling, which was not left for 48 hours in an environment of 60 ° C., was 5.

実施例１は、機能性部材用工程材料として、インクジェット用フィルム（機能性部材）上に剥離層を有する第１の工程用部材と、基材の一方の面に粘着層を有する第２の工程用部材とからなる機能性部材用工程材料を用いて、インクジェット出力機による印刷（産業的処理）を施した後、インクジェット用フィルム（機能性部材）から剥離層、粘着層、および基材を剥離したため、インクジェット用フィルム（機能性部材）に粘着層が残ることのないものとなった。   In Example 1, as a functional material process material, a first process member having a release layer on an inkjet film (functional member) and a second process having an adhesive layer on one surface of a substrate Using functional material process material consisting of materials for printing, after printing (industrial processing) with an ink jet output machine, peel off the release layer, adhesive layer, and substrate from the ink jet film (functional material) Therefore, the pressure-sensitive adhesive layer did not remain on the inkjet film (functional member).

また、インクジェット用フィルム（機能性部材）から剥離された工程用部材部分（剥離層、粘着層、および基材）においても、粘着層表面に粘着性を有することなく取り扱い性に優れたものとなった。   In addition, even in process member parts (peeling layer, adhesive layer, and substrate) peeled from the inkjet film (functional member), the surface of the adhesive layer is not sticky and has excellent handleability. It was.

一方、比較例１は、実施例１と同様のインクジェット用フィルム（機能性部材）と、実施例１で作製した第２の工程用部材と同様の工程用部材を用いて、インクジェット出力機による印刷（産業的処理）を施した後、インクジェット用フィルム（機能性部材）から、工程用部材（粘着層、および基材）を剥離したが、実施例１と異なり、インクジェット用フィルム（機能性部材）上に剥離層を有していないため、インクジェット用フィルム（機能性部材）に粘着層が残る箇所があった。   On the other hand, Comparative Example 1 uses the same inkjet film (functional member) as in Example 1 and the same process member as the second process member produced in Example 1, and prints using an inkjet output machine. After applying (industrial treatment), the process members (adhesive layer and substrate) were peeled from the inkjet film (functional member), but unlike Example 1, the inkjet film (functional member). Since there was no peeling layer on the top, there were places where the adhesive layer remained on the inkjet film (functional member).

また、インクジェット用フィルム（機能性部材）から剥離された工程用部材（粘着層、および基材）においても、粘着層表面に粘着性を有しているため取り扱い性の悪いものとなった。   In addition, the process members (adhesive layer and substrate) peeled from the inkjet film (functional member) also had poor handleability because of the adhesiveness on the adhesive layer surface.

実施例２は、光拡散フィルム（機能性部材）上に剥離層、粘着層、および基材をこの順に有する機能性部材用工程材料を用いて、型抜機による打ち抜き加工（産業的処理）を施した後、光拡散フィルム（機能性部材）から工程用部材部分（剥離層、粘着層、および基材）を剥離したため、光拡散フィルム（機能性部材）に粘着層が残ることのないものとなり、またその後の環境（貼合後６０℃の環境下に４８時間放置）によって工程用部材を剥離する際の剥離強度が左右されず、安定した生産性を維持することができるものとなった。   In Example 2, a functional member process material having a release layer, an adhesive layer, and a base material in this order on a light diffusion film (functional member) is subjected to punching processing (industrial processing) by a die cutting machine. Then, since the process member part (peeling layer, adhesive layer, and substrate) was peeled from the light diffusion film (functional member), the adhesive layer would not remain on the light diffusion film (functional member), Moreover, the peeling strength at the time of peeling the process member was not influenced by the subsequent environment (left for 48 hours in an environment of 60 ° C. after bonding), and stable productivity could be maintained.

また、光拡散フィルム（機能性部材）から剥離された工程用部材部分（剥離層、粘着層、および基材）においても、型抜機により機能性部材用工程材料の光拡散層を有していない方の面から、剥離層、粘着層、ポリエステルフィルム（基材）を残すように半抜きし、必要箇所以外の光拡散フィルムを剥離した際には、粘着層表面に粘着性を有するものではないため、非常に取り扱い性の優れたものとなった。   In addition, the process member portion (peeling layer, adhesive layer, and substrate) peeled from the light diffusion film (functional member) does not have the light diffusion layer of the functional member process material by the die cutting machine. From the other side, when the release layer, the pressure-sensitive adhesive layer, and the polyester film (base material) are half-leaved and the light diffusion film other than the necessary part is peeled off, the surface of the pressure-sensitive adhesive layer is not sticky Therefore, it became very easy to handle.

一方、比較例２は、実施例２と同様の光拡散フィルム（機能性部材）上に、粘着層、および基材をこの順に有する機能性部材用工程材料を用いて、型抜機による打ち抜き加工（産業的処理）を施した後、光拡散フィルム（機能性部材）から工程部材（粘着層、および基材）を剥離したが、実施例２と異なり、光拡散フィルム（機能性部材）上に剥離層を有していないため、光拡散フィルム（機能性部材）に粘着層が残る箇所があった。またその後の環境（貼合後６０℃の環境下に４８時間放置）によって、工程用部材を剥離する際の剥離強度が左右してしまい、安定した生産性を維持することができないものとなった。   On the other hand, in Comparative Example 2, a functional member process material having an adhesive layer and a base material in this order on the same light diffusion film (functional member) as in Example 2 was punched by a die cutting machine ( After applying industrial treatment, the process members (adhesive layer and substrate) were peeled from the light diffusion film (functional member), but unlike Example 2, it was peeled on the light diffusion film (functional member). Since it did not have a layer, there existed a part with which the adhesion layer remains in a light-diffusion film (functional member). Moreover, the peeling strength at the time of peeling off the process member depends on the subsequent environment (left for 48 hours in an environment of 60 ° C. after bonding), and stable productivity cannot be maintained. .

また、光拡散フィルム（機能性部材）から剥離された工程用部材（粘着層、および基材）においても、型抜機により機能性部材用工程材料の光拡散層を有していない方の面から、粘着層、ポリエステルフィルム（基材）を残すように半抜きし、必要箇所以外の光拡散フィルムを剥離した際には、粘着層表面に粘着性を有しているため、取り扱い性の悪いものとなった。   Moreover, also in the process member (adhesive layer and base material) peeled from the light diffusion film (functional member), from the side not having the light diffusion layer of the functional material process material by the die cutting machine When the adhesive layer and the polyester film (base material) are left in half, and the light diffusion film other than the necessary part is peeled off, the surface of the adhesive layer has adhesiveness, so that the handleability is poor. It became.
