技術分野 Technical field
[0001] 本発明は、金属光沢に優れ、し力も絶縁性ある図柄を、安定して品質よく転写可能で ある転写フィルム、その製造方法、及びそれを使用した成形品に関するものである。 背景技術 [0001] The present invention relates to a transfer film capable of stably transferring a pattern having excellent metallic luster and insulating properties with good quality, a method for manufacturing the same, and a molded article using the same. Background technology
[0002] 特許文献 1には、金属光沢を有する絶縁性ある図柄を有する金属蒸着フィルムを得 るため、基材フィルムに水溶性塗料層を部分的に設け、その上に金属蒸着層と、透 明無機蒸着層 (金属酸ィ匕薄膜)を積層して、水洗、乾燥するという方法が提案されて いる。そして、上記金属蒸着フィルムは包装材料等のほか転写箔 (転写フィルム）とし ても使用されるものである。しかし、例えば上記金属蒸着フィルム力 金属蒸着層を 極薄で不連続な絶縁性金属蒸着層（絶縁性金属薄膜)とした絶縁性転写箔 (絶縁性 転写フィルム)のとき、金属蒸着層上に単に透明無機蒸着層を積層しただけでは、水 洗時に、絶縁性金属蒸着層の脱落が生じるという欠点があり、また、この絶縁性転写 箔をインモールド成形に使用した場合、成形品のゲート部及び曲面部にクラックが発 生し、良好な外観を得難いばかりか、このクラック発生部分が高温高湿条件下で金属 光沢が消失し、耐久性が悪 、と 、う欠点があった。 [0002] Patent Document 1 discloses that in order to obtain a metallized film having an insulating pattern with metallic luster, a water-soluble paint layer is partially provided on a base film, and a metallized layer and a transparent metallized layer are formed on the base film. A method has been proposed in which a clear inorganic vapor deposited layer (metallic acid thin film) is laminated, washed with water, and dried. The metallized film mentioned above is used not only as a packaging material but also as a transfer foil (transfer film). However, for example, in the case of an insulating transfer foil (insulating transfer film) in which the metal vapor deposited layer is an extremely thin and discontinuous insulating metal vapor deposited layer (insulating metal thin film), the metal vapor deposited layer is simply If only a transparent inorganic vapor-deposited layer is laminated, the insulating metal vapor-deposited layer will fall off when washed with water. Also, if this insulating transfer foil is used for in-mold molding, the gate area and Cracks occur on the curved surface, making it difficult to obtain a good appearance, and the cracked areas lose their metallic luster under high temperature and high humidity conditions, resulting in poor durability.

発明が解決しょうとする課題 Problems that the invention seeks to solve
[0003] 本発明は、前述の如き、従来技術の欠点を解消し、スズ薄膜等の絶縁性金属薄膜 を使用し、従来になぐ金属光沢、及び絶縁性に優れた耐久性ある絶縁性転写フィ ルムを提供することを課題とするものであり、同時に、前記絶縁性転写フィルムの製 造方法、及び該転写フィルムを使用した成形品の提供をも課題とする。 [0003] The present invention eliminates the drawbacks of the prior art as described above, uses an insulating metal thin film such as a tin thin film, and produces a durable insulating transfer film with unprecedented metallic luster and excellent insulation properties. The object of the present invention is to provide a method for producing the above-mentioned insulating transfer film, and at the same time, to provide a molded article using the transfer film.
課題を解決するための手段 Means to solve problems
[0004] 本発明では、絶縁性金属薄膜に、水蒸気、及び酸素バリア機能の高！ヽ金属酸化薄 膜と耐水性榭脂層を積層することにより、上記課題を解決した。 [0004] In the present invention, an insulating metal thin film has a high water vapor and oxygen barrier function.ヽMetal oxide thin The above problem was solved by laminating the membrane and the water-resistant resin layer.
[0005] すなわち、本発明では、プラスチックフィルム上に離型層、及び保護層を設け、その 上に、模様状に水溶性塗料を塗布して水溶性塗料層を設けた後に、絶縁性金属薄 膜、及び金属酸化薄膜を順次設け、更に、前記金属酸化薄膜上に耐水性榭脂層を 設けた後、水洗して、前記水溶性塗料層、及び前記水溶性塗料層上に積層された 前記絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層を除去するとともに、前記 水溶性塗料層が存在しない部分の前記絶縁性金属薄膜、金属酸化薄膜、及び耐水 性榭脂層を残存させた後、接着層を設けることにより、絶縁性転写フィルムを製造す ることを特徴とする。 [0005] That is, in the present invention, a release layer and a protective layer are provided on a plastic film, a water-soluble paint is applied thereon in a pattern, a water-soluble paint layer is provided, and then an insulating metal thin layer is formed. A film and a metal oxide thin film were sequentially provided, and a water-resistant resin layer was further provided on the metal oxide thin film, and then washed with water and laminated on the water-soluble paint layer and the water-soluble paint layer. The insulating metal thin film, metal oxide thin film, and water-resistant resin layer were removed, and the insulating metal thin film, metal oxide thin film, and water-resistant resin layer remained in the areas where the water-soluble paint layer did not exist. After that, an adhesive layer is provided to produce an insulating transfer film.
[0006] このようにして得られる本発明の絶縁性転写フィルムは、プラスチックフィルムの離 型層上に、保護層、絶縁性金属薄膜、金属酸化薄膜、耐水性榭脂層、及び接着層 が順次設けられており、かつ絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層 が同一の図柄状に積層されている。ここで、絶縁性金属薄膜、金属酸化薄膜、及び 耐水性榭脂層が同一の図柄状に積層されているとは、絶縁性金属薄膜、金属酸ィ匕 薄膜、及び耐水性榭脂層が同一の図柄で、かつ絶縁性金属薄膜の真上に金属酸 化薄膜が、金属酸ィ匕薄膜の真上に耐水性榭脂層が積層されていることをいう。 また、保護層、絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層は単に積層さ れているのではなぐ保護層、絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層 がー体ィ匕されて積層されている。 [0006] The insulating transfer film of the present invention obtained in this manner has a protective layer, an insulating metal thin film, a metal oxide thin film, a water-resistant resin layer, and an adhesive layer sequentially formed on the release layer of the plastic film. An insulating metal thin film, a metal oxide thin film, and a water-resistant resin layer are laminated in the same pattern. Here, the fact that the insulating metal thin film, metal oxide thin film, and water-resistant resin layer are laminated in the same pattern means that the insulating metal thin film, metal oxide thin film, and water-resistant resin layer are the same. This refers to a metal oxide thin film laminated directly above the insulating metal thin film, and a water-resistant resin layer laminated directly above the metal oxide thin film. In addition, the protective layer, insulating metal thin film, metal oxide thin film, and water-resistant resin layer are not simply laminated. The body is stacked and stacked.
このように、保護層、絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層が積層一 体ィ匕されているため、その製造工程及び製造後のいずれにおいても、絶縁性金属薄 膜の脱落を防止でき、また、絶縁性転写フィルムをインモールド成形に使用した場合 、成形品のゲート部及び曲面部にクラックが発生し難ぐ良好な外観が得られるばか りか、高温高湿条件下で金属光沢が消失しないので耐久性がよいなど、品質のよい 絶縁性転写フィルムを得ることができる。 In this way, since the protective layer, the insulating metal thin film, the metal oxide thin film, and the water-resistant resin layer are laminated together, the insulating metal thin film can be easily removed during both the manufacturing process and after manufacturing. In addition, when an insulating transfer film is used for in-mold molding, it not only prevents cracks from forming on the gate and curved surfaces of the molded product, resulting in a good appearance, but also under high temperature and high humidity conditions. It is possible to obtain a high-quality insulating transfer film that has good durability and does not lose its metallic luster.
[0007] なお、本発明の製造方法において、水溶性塗料層の除去を精度よく実施し、品質 のよい絶縁性転写フィルムを得るには、保護層上に水溶性塗料層が存在する状態で 、水溶性塗料層が存在しない部分の保護層、絶縁性金属薄膜、金属酸化薄膜、及 び耐水性榭脂層を積層一体ィ匕することが必要であり、そうするためには、 a)絶縁性 金属薄膜が島状構造であり、かつ金属酸ィ匕薄膜の厚さを 3〜100nmの範囲とするこ と、及び、 b)耐水性榭脂層に使用する榭脂塗料が保護層まで浸透するように、該榭 脂塗料の粘度を低くしてコーティングするのが好ましぐそのため、耐水性榭脂層の コーティング法は、リバースコート法であるのが好ましい。 [0007] In addition, in the production method of the present invention, in order to accurately remove the water-soluble paint layer and obtain a high-quality insulating transfer film, it is necessary to remove the water-soluble paint layer while the water-soluble paint layer is present on the protective layer. Protective layers in areas where there is no water-soluble paint layer, insulating metal thin films, metal oxide thin films, and In order to do so, a) the insulating metal thin film has an island-like structure, and the thickness of the metal acid thin film is 3 to 100 nm. b) It is preferable to coat the water-resistant resin layer with a low viscosity so that the resin paint used for the water-resistant resin layer can penetrate into the protective layer. The coating method for the water-resistant resin layer is preferably a reverse coating method.
[0008] 更に、耐水性榭脂層の厚さは、水溶性塗料層の除去が困難な状態 (ポーラスな水 溶性塗料層の表面凹凸が平らに埋まるような状態)にならないように、水溶性塗料層 の厚さの 1Z3以下、特に 2〜20%とするのが好ましい。通常、この耐水性榭脂層の 厚さは、 0. 01 μ m力ら 0. 4 μ m程度の厚さに設ければよく、特に 0. 2 μ m以下に設 けるのがよい。 [0008] Furthermore, the thickness of the water-resistant resin layer is adjusted so that the water-soluble paint layer does not become difficult to remove (a state in which the surface irregularities of the porous water-soluble paint layer are flattened). It is preferably 1Z3 or less, particularly 2 to 20% of the thickness of the paint layer. Normally, the thickness of this water-resistant resin layer is about 0.01 μm to 0.4 μm, and it is particularly preferable to set it to 0.2 μm or less.
[0009] カゝかる耐水性榭脂層を設けるための榭脂としては、通常コーティングに使用される 耐水性ある榭脂、例えば、エステル系榭脂、アクリル系榭脂、塩ィ匕ビュル系榭脂、酢 酸ビュル系榭脂などがいずれも使用できるが、インモールド成形などに適用する場 合には、架橋型の榭脂、例えばイソシァネート結合により架橋するウレタン系榭脂ゃ アクリル ·ウレタン系榭脂を使用するのが好まし 、。 [0009] As the resin for forming the water-resistant resin layer, water-resistant resins that are usually used for coatings, such as ester resin, acrylic resin, salt-based resin, etc. However, when used in in-mold molding, cross-linked resins such as urethane resins, acrylic and urethane resins that are crosslinked through isocyanate bonds, etc. can be used. It is preferable to use fat.
[0010] 本発明における絶縁性金属薄膜とは金属光沢と絶縁性を兼ね備えた金属薄膜の ことで、従来技術に従って蒸着法で設けることができる。通常、島のサイズが ιοΑ〜 [0010] The insulating metal thin film in the present invention refers to a metal thin film that has both metallic luster and insulating properties, and can be provided by a vapor deposition method according to conventional techniques. Usually the size of the island is ιοΑ~
2 μ m (lnm〜2 μ m)で、島の間隔が 20 A〜 5000 A (2nm〜500nm)である島状 構造となるような薄膜とするのがよぐ絶縁性金属薄膜を設けるための金属としては、 スズ、インジユーム、鉛、亜鉛、ビスマス、チタン、クロム、鉄、コノ レト、ニッケル、珪素 、ゲルマ-ユーム又はこれらの合金力 なる群力 選ばれるものが使用できる。特に スズ又はインジユームであるのが好まし 、。 The best way to provide an insulating metal thin film is to form a thin film with an island-like structure of 2 μm (lnm to 2 μm) and an island spacing of 20 A to 5000 A (2 nm to 500 nm). As the metal, a metal selected from tin, indium, lead, zinc, bismuth, titanium, chromium, iron, copper, nickel, silicon, germanium, or an alloy thereof can be used. In particular, tin or indium is preferred.
[ooii] 絶縁性金属薄膜を上記の島状構造とするには、プラスチックフィルム Z離型層 Z保 護層 Z模様状の水溶性塗料層,絶縁性金属薄膜からなる積層体の水溶性塗料層 が存在しない部分の全光線透過率を 10〜50%とするのがよい。また、ここに絶縁性 とは、絶縁破壊電圧が 1000V以上であることをいう。 [ooii] In order to make the insulating metal thin film into the above-mentioned island-like structure, a plastic film Z mold release layer Z protective layer Z patterned water-soluble paint layer, a water-soluble paint layer of the laminate consisting of the insulating metal thin film It is preferable that the total light transmittance of the area where no light exists is 10 to 50%. Insulation here means that the dielectric breakdown voltage is 1000V or more.
[0012] 本発明の絶縁性転写フィルムは、プラスチックフィルムと離型層の間に下塗層を設 けたものであってもよい。 [0013] 更に、本発明の絶縁性転写フィルムでは、プラスチックフィルムの離型層上に、着 色印刷層を設けた上に前記保護層を設けてもよぐそうすることによって、着色印刷 模様を表面に有する金属光沢に優れた図柄を安定して転写できる絶縁性転写フィ ルムの製造が可能となる。 [0012] The insulating transfer film of the present invention may have an undercoat layer between the plastic film and the release layer. [0013]Furthermore, in the insulating transfer film of the present invention, a colored printing layer is provided on the release layer of the plastic film, and then the protective layer is provided, thereby forming a colored printing pattern. It becomes possible to manufacture an insulating transfer film that can stably transfer designs with excellent metallic luster on the surface.
[0014] 次に、絶縁性金属薄膜に積層される金属酸ィ匕薄膜は、絶縁性金属薄膜の金属光 沢と絶縁性を維持し、耐腐食性を向上すると共に、絶縁性金属薄膜のキズ発生を防 止するためのものであり、例えば酸ィ匕アルミ-ユーム薄膜や酸ィ匕珪素薄膜等によるの が有用である。金属酸化薄膜の厚さは、通常、 lOOnm以下程度の厚さに設ければよ ぐ酸ィ匕珪素薄膜は 8〜60nm程度であるのが好ましぐ酸ィ匕アルミ-ユーム薄膜は 3 〜30nm程度の厚さで十分な効果を得ることができる。しかし、金属酸化薄膜上に形 成される耐水性榭脂層が保護層、絶縁性金属薄膜、及び金属酸化薄膜と積層一体 化して、安定した品質のよい絶縁性転写フィルムの製造を可能とするためには、 3〜 lOOnm程度の厚さであるのが好ましい。なお、厚さが 3nm未満であると耐腐食性が 悪くなり、 lOOnmを超えると、特に転写時に金属酸ィ匕薄膜にクラックを生じ易くなり、 結果的に耐腐食性も低下する。 [0014] Next, the metal acid thin film laminated on the insulating metal thin film maintains the metallic luster and insulation properties of the insulating metal thin film, improves corrosion resistance, and prevents scratches on the insulating metal thin film. This is to prevent the occurrence of such problems, and it is useful to use, for example, a thin film of aluminum or silicon. The thickness of the metal oxide thin film is usually about 100 nm or less.The thickness of the silicon oxide film is preferably about 8 to 60 nm, and the thickness of the aluminum oxide film is preferably 3 to 30 nm. A sufficient effect can be obtained with a certain thickness. However, the water-resistant resin layer formed on the metal oxide thin film is laminated and integrated with the protective layer, the insulating metal thin film, and the metal oxide thin film, making it possible to manufacture a stable and high-quality insulating transfer film. For this purpose, the thickness is preferably about 3 to 10 nm. Note that if the thickness is less than 3 nm, the corrosion resistance will deteriorate, and if it exceeds lOOnm, the metal oxide thin film will be more likely to crack, especially during transfer, resulting in a decrease in corrosion resistance.
[0015] 絶縁性金属薄膜を図柄状に形成するため、本発明の方法では、保護層上に水溶 性塗料を模様状 (図柄の陰型）に塗布して水溶性塗料層を設け、その上から全面に 絶縁性金属薄膜、及び金属酸化薄膜を設けた上に、さらに耐水性榭脂層を設けた 後、水洗して水溶性塗料層を溶解除去するものであるので、水溶性塗料層上の絶縁 性金属薄膜、金属酸化薄膜、及び耐水性榭脂層は、水溶性塗料層の溶解に伴って 、模様状に除去されるが、水溶性塗料層の存在しない部分では、耐水性榭脂層の榭 脂が、保護層表面まで浸透し、保護層、絶縁性金属薄膜、金属酸化薄膜、及び耐水 性榭脂層が積層一体ィ匕するため、水溶性塗料層が存在しない部分では、保護層、 絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層が積層一体化した状態で、か つ絶縁性金属薄膜、金属酸化薄膜、及び耐水性榭脂層が所望の図柄に、精度よく 残存し、金属光沢ある図柄を形成するのである。 [0015] In order to form an insulating metal thin film in a pattern, in the method of the present invention, a water-soluble paint is applied on the protective layer in a pattern (negative shape of the pattern) to form a water-soluble paint layer, and then After forming an insulating metal thin film and a metal oxide thin film on the entire surface, a water-resistant resin layer is further applied, and the water-soluble paint layer is dissolved and removed by washing with water. The insulating metal thin film, metal oxide thin film, and water-resistant resin layer are removed in a pattern as the water-soluble paint layer dissolves, but in areas where the water-soluble paint layer does not exist, the water-resistant resin layer is removed. The resin in the layer penetrates to the surface of the protective layer, and the protective layer, insulating metal thin film, metal oxide thin film, and water-resistant resin layer are laminated together, so in areas where there is no water-soluble paint layer, there is no protection. layer, an insulating metal thin film, a metal oxide thin film, and a water-resistant resin layer are laminated and integrated, and the insulating metal thin film, metal oxide thin film, and water-resistant resin layer are precisely formed into the desired pattern. It remains and forms a pattern with a metallic luster.

[0018] また、離型層としては、エーテル系、エステル系、エポキシ系、アクリル系、シリコン 系、ワックス系等の榭脂、及び共重合体を一種又は二種以上使用するのが好ましい 。更に、ハードコート性を要求される用途には、離型層を紫外線硬化型アクリル榭脂 等のいわゆるハードコート性を有する榭脂で形成しておくことが好ましい。 [0018] Furthermore, as the release layer, it is preferable to use one or more types of resins and copolymers such as ether, ester, epoxy, acrylic, silicone, and wax resins. Furthermore, for applications requiring hard coat properties, it is preferable to form the release layer with a resin having so-called hard coat properties, such as an ultraviolet curable acrylic resin.

Also, add some extender pigment to the water-soluble paint layer.

In this case, an undercoat layer is added between the plastic film and the release layer in order to improve the releasability between the plastic film and the release layer and to prevent the plastic film from peeling off or tearing during transfer.

As the resin used for the undercoat layer, thermosetting resins such as melamine resin, aminoalkyd resin, epoxy resin, acrylic resin, silicone resin, etc. can be used. In particular, melamine-based resin and acrylic resin are preferred.
[0022] なお、本発明の絶縁性転写フィルムをプラスチック基材上に転写して、プラスチック 基材上に、接着層、耐水性榭脂層、金属酸化薄膜、絶縁性金属薄膜、保護層、及び 離型層が順次設けられており、かつ耐水性榭脂層、金属酸化薄膜、及び絶縁性金 属薄膜が同一の図柄状に積層された成形品を得ることができる。 [0022] The insulating transfer film of the present invention is transferred onto a plastic substrate, and an adhesive layer, a water-resistant resin layer, a metal oxide thin film, an insulating metal thin film, a protective layer, and A mold release layer is provided in sequence, including a water-resistant resin layer, a metal oxide thin film, and an insulating gold layer. It is possible to obtain a molded article in which thin films of the same type are laminated in the same pattern.
このようにして得た本発明の成形品は、耐水性榭脂層、金属酸化薄膜、絶縁性金 属薄膜、及び保護層が積層一体化されているので、本発明の絶縁性転写フィルムを 使用してインモールド成形で成形品を製造した場合、成形品のゲート部及び曲面部 にクラックが発生し難ぐ良好な外観が得られるばかりか、高温高湿条件下で金属光 沢が消失しないので耐久性がよぐ品質のよい成形品となる。 The thus obtained molded article of the present invention has a water-resistant resin layer, a metal oxide thin film, an insulating metal thin film, and a protective layer integrated into one layer, so the insulating transfer film of the present invention can be used.

発明の効果 Effect of the invention
本発明の絶縁性転写フィルム、及び該絶縁性転写フィルムを使用して得る本発明 の成形品は、下記の効果を有する。 The insulating transfer film of the present invention and the molded article of the present invention obtained using the insulating transfer film have the following effects.
本発明の絶縁性転写フィルムは、前記の通り、保護層、絶縁性金属薄膜、金属酸 化薄膜、及び耐水性榭脂層が積層一体化されているため、 As mentioned above, the insulating transfer film of the present invention has a protective layer, an insulating metal thin film, a metal oxide thin film, and a water-resistant resin layer integrated into one layer.
1)絶縁性金属薄膜が島状構造のため、絶縁性金属薄膜表面にキズが入り易いが、 絶縁性転写フィルム製造時の水洗工程において、絶縁性金属薄膜が脱落したり、こ すれによるスリキズを生じることがな 、ので、金属光沢ある所望の図柄を精度よく転写 できる絶縁性転写フィルムを提供できる。 1) Since the insulating metal thin film has an island-like structure, it is easy to get scratches on the surface of the insulating metal thin film, but in the washing process during the manufacturing of the insulating transfer film, the insulating metal thin film does not fall off or scratches due to rubbing can be prevented. Therefore, it is possible to provide an insulating transfer film that can accurately transfer a desired pattern with metallic luster.
2)保護層と絶縁性金属薄膜の間の密着性が向上するので、保護層に使用する榭 脂の種類の選定範囲が広がるとともに、製造条件 (コーティング機械の種類、乾燥温 度等)の制約が少なくなつた。 2) Since the adhesion between the protective layer and the insulating metal thin film is improved, the range of selection of the type of resin used for the protective layer is expanded, and restrictions on manufacturing conditions (type of coating machine, drying temperature, etc.) are reduced. has decreased.
3)絶縁性金属薄膜の腐食が生じにくいため、耐水性榭脂層を設けた後、すぐに水洗 工程及び接着工程を行う必要がなぐ水洗工程あるいは接着工程まで長期保存が可 能となり、納期対応が容易になった。 4)インモールド成形により成形品を製造する場合にも、保護層、絶縁性金属薄膜、 金属酸化薄膜、及び耐水性榭脂層が積層一体化されていることに加え、耐水性榭 脂層がインモールド成形時に絶縁性転写フィルムに生じる張力やゲート部力 流れ 込む樹脂の熱や圧力による応力を緩衝する作用があるため、成形品の曲面部ゃゲ ート部で絶縁性金属薄膜にクラックが発生し難くい。特に、耐水性榭脂層に使用する 榭脂をイソシァネート結合により架橋するウレタン系榭脂ゃアクリル 'ウレタン系榭脂と しておけば、より耐熱性が向上するので、曲面部やゲート部の位置がエッジ部の場合 はもちろん、ゲート部の位置がより耐熱性が要求される中央部の場合であっても、ゲ ート部にクラックが発生し 1 、成形品の形状やプラスチック基材の種類の選択幅が 広がる。 3) Since the insulating metal thin film is less likely to corrode, there is no need to immediately perform the washing and bonding process after applying the water-resistant resin layer.It can be stored for a long period of time until the washing or bonding process, which can meet delivery deadlines. has become easier. 4) When manufacturing molded products by in-mold molding, in addition to the protective layer, insulating metal thin film, metal oxide thin film, and water-resistant resin layer being laminated together, the water-resistant resin layer is Tension and gate force generated in the insulating transfer film during in-mold molding.Since it has the effect of buffering the stress caused by the heat and pressure of the flowing resin, cracks may occur in the insulating metal thin film at the curved surface of the molded product and at the gate. Hard to occur. In particular, if the water-resistant resin layer is made of urethane-based resin or acrylic resin, which is cross-linked through isocyanate bonds, the heat resistance will be further improved, and the position of curved surfaces and gate areas will be improved. Cracks can occur in the gate, not only when it is at the edge, but also when the gate is located in the center, where higher heat resistance is required1, and the shape of the molded product and the type of plastic base material The range of choices expands.
5)インモールド成形時にゲート部カも榭脂が流れ込む際に、ゲート部近傍の接着層 が溶解、剥離することがないので、本発明の成形品の接着層とプラスチック基材間と の密着性が良好である。 5) When resin flows into the gate part during in-mold molding, the adhesive layer near the gate part does not dissolve or peel off, which improves the adhesion between the adhesive layer of the molded product of the present invention and the plastic base material. is good.
6)本発明の成形品は、 65°C X 95% X 24時間及び 60°C X 80% X 96時間と!/、ぅ携 帯電話やオーディオ製品に要求される高温高湿試験でも、全光線透過率が 60%を 越えず、腐食により絶縁性金属薄膜が消失することがないので、非常に広範な用途 に使用可能である。 6) The molded product of the present invention can withstand total light transmission even in the high temperature and high humidity tests required for mobile phones and audio products, such as 65°C x 95% x 24 hours and 60°C x 80% x 96 hours. Since the corrosion rate does not exceed 60% and the insulating metal thin film does not disappear due to corrosion, it can be used in a very wide range of applications.
7)また、耐水性榭脂層を設けることにより、いずれも榭脂からなる耐水性榭脂層と接 着層とが直接接することになるので、接着層に使用する榭脂の種類の選定範囲が広 がり、それにより転写できるプラスチック基材の種類も多くなる。その結果、絶縁性転 写フィルムの用途が広がるとともに生産性も向上する。 発明を実施するための最良の形態 7) Furthermore, by providing the water-resistant resin layer, the adhesive layer will come into direct contact with the water-resistant resin layer, which is made of resin. This will expand the number of types of plastic substrates that can be transferred. As a result, the applications of insulating transfer film will expand and productivity will improve.

実施例 1で得た積層フィルム (A)を水洗して、水溶性塗料層、及び水溶性塗料層 上のスズ薄膜 Z酸ィ匕アルミ-ユーム薄膜を除去するとともに、水溶性塗料層が存在し ない部分のスズ薄膜 Z酸ィ匕アルミ-ユーム薄膜を残存させたシートフィルムを得た。 得られたシートフィルムは、水溶性塗料層が存在しない部分、つまりは本来スズ薄膜 Z酸ィ匕アルミ-ユーム薄膜を残存させなければならな 、部分にぉ 、て、酸化アルミ- ユーム薄膜とともにスズ薄膜が一部脱落した不適部分があった。得られたシートフィ ルムの酸ィ匕アルミ-ユーム薄膜側にアクリル系榭脂よりなる厚さ 1 mの接着層を設 け、ポリエチレンテレフタレートフィルム z下塗層 Z離型層 Z保護層 Zスズ薄膜 Z酸 化アルミ-ユーム薄膜 z接着層からなり、スズ薄膜 z酸ィ匕アルミ-ユーム薄膜が金属 光沢を有する同一の図柄状に積層されてはいるものの該図柄が一部脱落した不適 部分がある絶縁性転写フィルムを得た。不適部分は後に切り落とし、歩留まり 10%と 低い値であった。 The laminated film (A) obtained in Example 1 was washed with water to remove the water-soluble paint layer and the tin thin film on the water-soluble paint layer, and to remove the water-soluble paint layer. A sheet film was obtained in which the tin thin film remained in the areas where the tin thin film was not present. The resulting sheet film is coated with tin along with the aluminum oxide thin film in the areas where the water-soluble paint layer does not exist, that is, where the tin thin film should originally remain. There were some unsuitable areas where some of the thin film had fallen off.

[0029] 表 1に示されるように、比較例 1の絶縁性転写フィルムでは、スズ薄膜上に酸ィ匕アル ミニユーム薄膜を設けることにより、水洗工程における表面スリキズは防止できたが、 保護層からスズ薄膜が脱落するのを防止できな力つた。 [0029] As shown in Table 1, in the insulating transfer film of Comparative Example 1, oxidized aluminum was added on the tin thin film. By providing a minium thin film, we were able to prevent surface scratches during the washing process, but we were unable to prevent the tin film from falling off from the protective layer.
これは、絶縁性金属薄膜に使用する金属がスズのように、比較的柔らかぐ榭脂に 対する付着力が弱い金属である場合は、スズ薄膜と保護層との密着力を強くする必 要があり、特に水溶性塗料層による図柄が細かい場合、水洗工程で使用される水圧 洗浄の水圧を強める必要があるため、より高い密着力が必要となる。 This is because if the metal used for the insulating metal thin film is a relatively soft metal such as tin that has weak adhesion to resin, it is necessary to strengthen the adhesion between the tin thin film and the protective layer. However, if the pattern is particularly detailed due to the water-soluble paint layer, it is necessary to increase the water pressure of the water pressure washing used in the washing process, which requires higher adhesion.
しかし、比較例 1の絶縁性転写フィルムは、保護層とスズ薄膜との密着力が弱いためHowever, the insulating transfer film of Comparative Example 1 has weak adhesion between the protective layer and the tin thin film.
、保護層からスズ薄膜が脱落するのを防止できな力つたのである。 However, it was impossible to prevent the thin tin film from falling off from the protective layer.
実施例 1、及び 2の本発明の絶縁性転写フィルムはいずれも、スリキズおよびスズ薄 膜の脱落のない、非常に品質のよい絶縁性転写フィルムとなった。これは、耐水性榭 脂層の樹脂が保護層まで浸透し、保護層 Zスズ薄膜 Z酸ィ匕アルミ-ユーム薄膜 Z耐 水性榭脂層が積層一体化している結果、保護層とスズ薄膜の密着力が強くなつたた めである。 Both of the insulating transfer films of the present invention in Examples 1 and 2 were of very good quality, with no scratches or falling off of the tin film. This is because the resin in the water-resistant resin layer penetrates into the protective layer, and the protective layer Z Tin Thin Film Z Aluminium-Yum Thin Film Z Water Resistant Resin Layer is laminated and integrated, resulting in the separation of the protective layer and the tin thin film. This is because the adhesion has become stronger.
<実施例 3 > 成形品の製造 <Example 3> Manufacturing of molded products
実施例 1の本発明の絶縁性転写フィルムを使用して、透明アクリル榭脂を用いてィ ンモールド成形し、携帯電話用筐体を製造した。 Using the insulating transfer film of the present invention in Example 1, in-mold molding was performed using transparent acrylic resin to produce a mobile phone casing.
なお、インモールド成形としては、榭脂を流し込むためのゲート部の位置を、（1)筐体 中央に設けた場合 (転写フィルムの耐熱性がより要求される）と（2)筐体のエッジ部に 設けた場合の二種の方法で、それぞれ携帯電話用筐体を製造した。 In addition, for in-mold molding, the position of the gate for pouring the resin is determined by (1) the case where it is provided in the center of the casing (more heat resistance of the transfer film is required) and (2) the case where it is placed at the edge of the casing. Two methods were used to manufacture mobile phone casings, one for each case.
