Description

本発明は、窓用装飾シートに関する。   The present invention relates to a decorative sheet for windows.

従来、窓用装飾シートの意匠性を向上させるために、表面に立体性をもたせることが行なわれてきた。その窓用装飾シートは、シート基材の片面に加熱凹凸塑性加工を施した後に、加熱凹凸塑性加工を施していない面に粘着剤層、剥離シートを積層させる方法により製造されてきた（例えば、特許文献１参照）。   Conventionally, in order to improve the designability of the decorative sheet for windows, it has been performed to give a three-dimensional surface. The window decorative sheet has been manufactured by a method of laminating a pressure-sensitive adhesive layer and a release sheet on a surface not subjected to heat uneven plastic processing after performing heat uneven plastic processing on one side of a sheet base material (for example, Patent Document 1).

しかし、シート基材の片面のみに加熱凹凸塑性加工を施す場合、深い加熱凹凸塑性加工を施すためにはシート基材が厚くなる。また加熱凹凸塑性加工そのものも難しい。このように、意匠性を向上させるために大きな立体性を付与することは困難であった。
特開平１１−１９８３０２号公報 However, in the case where the heating unevenness plastic processing is performed only on one surface of the sheet base material, the sheet base material becomes thick in order to perform the deep heating unevenness plastic processing. In addition, heating uneven plastic processing itself is difficult. Thus, it has been difficult to impart large three-dimensionality in order to improve design properties.
JP 11-198302 A

解決しようとする課題は、大きな立体性を付与することができない点である。また、窓の温度が直接シート基材に伝わり、シート基材の表面に結露する点である。さらに、窓との間にエアーが入って窓用装飾シートが膨らんだ際に、目立つ点である。また、窓に貼着しにくい点である。   The problem to be solved is that a large three-dimensionality cannot be imparted. In addition, the temperature of the window is directly transmitted to the sheet base material, and condensation occurs on the surface of the sheet base material. Furthermore, it is a conspicuous point when air enters between the windows and the window decorative sheet swells. Moreover, it is a point which is hard to stick on a window.

そこで、本発明に係る窓用装飾シートは、シート基材と粘着剤層と剥離シートを順次積層した窓用装飾シートに於て、全ての層に一体的にランダム模様凹凸形状が形成されており、かつ、上記剥離シートを剥離除去した貼着直前状態において、上記粘着剤層の露出面の凹凸形状を、多数の独立状小凹窪部と、該小凹窪部間に形成された連続陸部とをもって構成し、さらに、正味厚さ寸法Ｔ0 を50μｍ≦Ｔ0 ≦ 150μｍに設定するとともに、上記ランダム模様凹凸形状の表裏各面における深さ寸法Ｈ0 を 150μｍ≦Ｈ0 ≦ 500μｍに設定したものである。 Therefore, the decorative sheet for windows according to the present invention is a decorative sheet for windows in which a sheet base material, an adhesive layer, and a release sheet are sequentially laminated. And, in the state immediately before sticking after peeling off and removing the release sheet, the uneven shape of the exposed surface of the pressure-sensitive adhesive layer is a large number of independent small concave depressions and continuous land formed between the small concave depressions. Furthermore, the net thickness dimension T 0 is set to 50 μm ≦ T 0 ≦ 150 μm, and the depth dimension H 0 on the front and back surfaces of the random pattern unevenness is set to 150 μm ≦ H 0 ≦ 500 μm. It is a thing.

また、各小凹窪部に於て該小凹窪部の重心を通る幅寸法の平均値Ｗ0 を 0.5mm≦Ｗ0 ≦10mmに設定したものである。
また、粘着剤層の上記露出面の上記連続陸部が、同一平面状の平坦面部を有しているものである。
また、任意の縦断面における各平坦面部の幅寸法Ｌを 0.1mm≦Ｌ≦７mmに設定したものである。
また、上記粘着剤層の平坦面部の面積Ｓ1 と全体の面積Ｓ0 を３％≦（Ｓ1 ／Ｓ0 ）× 100≦50％を満たすように設定したものである。
また、上記シート基材１及び剥離シート３がポリエステルフィルムから成るものである。 Further, the average value W 0 of the width dimension passing through the center of gravity of each small concave portion is set to 0.5 mm ≦ W 0 ≦ 10 mm in each small concave portion.
Moreover, the said continuous land part of the said exposed surface of an adhesive layer has the flat surface part of the same plane shape.
Further, the width dimension L of each flat surface portion in an arbitrary longitudinal section is set to 0.1 mm ≦ L ≦ 7 mm.
The area S 1 of the flat surface portion of the pressure-sensitive adhesive layer and the entire area S 0 are set so as to satisfy 3% ≦ (S 1 / S 0 ) × 100 ≦ 50%.
The sheet substrate 1 and the release sheet 3 are made of a polyester film.

本発明の窓用装飾シートによれば、大きな立体性（高い装飾性、高い意匠性）を付与することができる。また、断熱性にも優れ、結露を防止することができる。さらに、窓との間にエアーが入って窓用装飾シートが膨らんだ際に、目立つことを防止することができる。また、窓に容易に貼着することができる。   According to the decorative sheet for windows of the present invention, large three-dimensionality (high decorativeness and high designability) can be imparted. Moreover, it is excellent in heat insulation and can prevent dew condensation. Furthermore, when air enters between the windows and the decorative sheet for windows swells, it can be prevented from standing out. Moreover, it can be easily attached to a window.

図１及び図２は、本発明の第１の実施の形態の使用状態を示す。この窓用装飾シートは、シート基材１と粘着剤層２と剥離シート３（図３参照）を順次積層した窓用装飾シートであって、剥離シート３を剥離して、粘着剤層２を窓Ａに貼着して使用する。以下説明するようなランダム模様凹凸形状Ｅを有し、高い意匠性が得られる。   1 and 2 show a use state of the first embodiment of the present invention. This decorative sheet for windows is a decorative sheet for windows in which a sheet substrate 1, an adhesive layer 2, and a release sheet 3 (see FIG. 3) are sequentially laminated. Attached to window A for use. It has a random pattern concavo-convex shape E as described below, and high designability is obtained.

シート基材１は、例えば、合成樹脂から成る。好ましくは、ポリエステルフィルムから成る。ポリエステルフィルムは、加熱凹凸塑性加工性、コスト等の面で適している。着色、蒸着加工、コーティング等により様々な意匠性を付与するのも好ましい。   The sheet substrate 1 is made of, for example, a synthetic resin. Preferably, it consists of a polyester film. The polyester film is suitable in terms of heating unevenness plastic workability and cost. It is also preferable to impart various design properties by coloring, vapor deposition, coating, or the like.

粘着剤層２は、例えば、合成樹脂から成る。好ましくは、加熱凹凸塑性加工前においてガラスに対する接着力を1.5 Ｎ／25mm以上に設定する。接着力が1.5 Ｎ／25mm未満の場合、窓Ａに貼着した窓用装飾シートが剥落してしまう。   The pressure-sensitive adhesive layer 2 is made of, for example, a synthetic resin. Preferably, the adhesive strength with respect to glass is set to 1.5 N / 25 mm or more before the heating uneven plastic processing. When the adhesive strength is less than 1.5 N / 25 mm, the window decorative sheet adhered to the window A is peeled off.

剥離シート３は、例えば、合成樹脂又は紙から成る。好ましくは、ポリエステルフィルムから成る。   The release sheet 3 is made of synthetic resin or paper, for example. Preferably, it consists of a polyester film.

図３に示すように、シート基材１と粘着剤層２と剥離シート３の全ての層に一体的にランダム模様凹凸形状Ｅが形成されている。
図４に示す剥離シート３を剥離除去した貼着直前状態において、粘着剤層２の露出面４の凹凸形状は、多数の独立状小凹窪部５と、小凹窪部５間に形成された連続陸部６とをもって構成されている。 As shown in FIG. 3, a random pattern uneven shape E is integrally formed on all layers of the sheet substrate 1, the pressure-sensitive adhesive layer 2, and the release sheet 3.
In the state immediately before sticking after peeling and removing the release sheet 3 shown in FIG. 4, the uneven shape of the exposed surface 4 of the pressure-sensitive adhesive layer 2 is formed between a large number of independent small recesses 5 and the small recesses 5. And a continuous land portion 6.

図３にもどって、正味厚さ寸法Ｔ0 が50μｍ≦Ｔ0 ≦ 150μｍに設定されている。本発明において「正味厚さ寸法」とは、シート基材１の表面７に直交する方向の厚さ寸法のことをいう。正味厚さ寸法Ｔ0 がＴ0 ＜50μｍの場合、強度が小さくなる。正味厚さ寸法Ｔ0 が 150μｍ＜Ｔ0 の場合、製造が困難である、意匠性が低くなったり、無駄に多くの材料を必要とする。 Returning to FIG. 3, the net thickness dimension T 0 is set to 50 μm ≦ T 0 ≦ 150 μm. In the present invention, the “net thickness dimension” refers to a thickness dimension in a direction orthogonal to the surface 7 of the sheet substrate 1. When the net thickness dimension T 0 is T 0 <50 μm, the strength is reduced. When the net thickness dimension T 0 is 150 μm <T 0 , it is difficult to manufacture, the design property is lowered, and a large amount of materials are required unnecessarily.

シート基材１の正味厚さ寸法Ｔ1 は、15μｍ≦Ｔ1 ≦75μｍに設定するのが好ましい。正味厚さ寸法Ｔ1 がＴ1 ＜15μｍの場合、強度不足となる虞れがある。正味厚さ寸法Ｔ1 が75μｍ＜Ｔ1 の場合、意匠性が低くなったり、無駄に多くの材料を必要とする虞れがある。 The net thickness dimension T 1 of the sheet substrate 1 is preferably set to 15 μm ≦ T 1 ≦ 75 μm. If the net thickness dimension T 1 is T 1 <15 μm, the strength may be insufficient. When the net thickness dimension T 1 is 75 μm <T 1 , the design property may be lowered or a large amount of material may be required unnecessarily.

粘着剤層２の正味厚さ寸法Ｔ2 は、15μｍ≦Ｔ2 ≦50μｍに設定するのが好ましい。正味厚さ寸法Ｔ2 がＴ2 ＜15μｍの場合、製造するのが困難になる虞れがある。正味厚さ寸法Ｔ2 が50μｍ＜Ｔ2 の場合、製造（乾燥工程等）に時間がかかるとともに、無駄に多くの材料を必要とする虞れがある。 The net thickness dimension T 2 of the pressure-sensitive adhesive layer 2 is preferably set to 15 μm ≦ T 2 ≦ 50 μm. If the net thickness dimension T 2 is T 2 <15 μm, it may be difficult to manufacture. When the net thickness dimension T 2 is 50 μm <T 2 , manufacturing (drying process or the like) takes time and there is a possibility that a lot of materials are wasted.

剥離シート３の正味厚さ寸法Ｔ3 は、20μｍ≦Ｔ3 ≦50μｍに設定するのが好ましい。正味厚さ寸法Ｔ3 がＴ3 ＜20μｍの場合、剥離の際に剥離シート３が破損する虞れがある。正味厚さ寸法Ｔ3 が50μｍ＜Ｔ3 の場合、無駄に多くの材料を必要とする虞れがある。 The net thickness dimension T 3 of the release sheet 3 is preferably set to 20 μm ≦ T 3 ≦ 50 μm. When the net thickness dimension T 3 is T 3 <20 μm, the release sheet 3 may be damaged during peeling. When the net thickness dimension T 3 is 50 μm <T 3 , there is a possibility that a large amount of material is unnecessary.

ランダム模様凹凸形状Ｅの表裏各面８，９における深さ寸法Ｈ0 が 150μｍ≦Ｈ0 ≦ 500μｍに設定されている。ランダム模様凹凸形状Ｅの深さ寸法Ｈ0 がＨ0 ＜ 150μｍの場合、意匠性が低くなるとともに、断熱性が小さくなる。ランダム模様凹凸形状Ｅの深さ寸法Ｈ0 が 500μｍ＜Ｈ0 の場合、加熱凹凸塑性加工の際に破損する虞れがある。すなわち、製造するのが困難である。 The depth dimension H 0 on each of the front and back surfaces 8, 9 of the random pattern uneven shape E is set to 150 μm ≦ H 0 ≦ 500 μm. When the depth dimension H 0 of the random pattern uneven shape E is H 0 <150 μm, the design property is lowered and the heat insulating property is reduced. When the depth dimension H 0 of the random pattern uneven shape E is 500 μm <H 0 , there is a risk of breakage during the heat uneven plastic processing. That is, it is difficult to manufacture.

連続陸部６は、同一平面状の平坦面部10を有している。任意の縦断面における各平坦面部10の幅寸法Ｌが 0.1mm≦Ｌ≦７mmに設定されている。幅寸法ＬがＬ＜ 0.1mmの場合、接着力が不足して窓用装飾シートが窓Ａから剥落してしまう。幅寸法Ｌが７mm＜Ｌの場合、意匠性が低いとともに、断熱性が小さい。   The continuous land portion 6 has a flat surface portion 10 that is coplanar. The width dimension L of each flat surface portion 10 in an arbitrary longitudinal section is set to 0.1 mm ≦ L ≦ 7 mm. When the width dimension L is L <0.1 mm, the adhesive strength is insufficient and the window decorative sheet is peeled off from the window A. When the width dimension L is 7 mm <L, the design property is low and the heat insulating property is small.

粘着剤層２の平坦面部10の面積Ｓ1 と全体の面積Ｓ0 が３％≦（Ｓ1 ／Ｓ0 ）× 100≦50％を満たすように設定されている。平坦面部８の面積Ｓ1 と全体の面積Ｓ0 が（Ｓ1 ／Ｓ0 ）× 100＜３％の場合、窓用装飾シートが窓Ａから剥がれやすい。平坦面部10の面積Ｓ1 と全体の面積Ｓ0 が50％＜（Ｓ1 ／Ｓ0 ）× 100の場合、断熱性が小さくなる。 The area S 1 of the flat surface portion 10 of the pressure-sensitive adhesive layer 2 and the entire area S 0 are set so as to satisfy 3% ≦ (S 1 / S 0 ) × 100 ≦ 50%. When the area S 1 of the flat surface portion 8 and the total area S 0 are (S 1 / S 0 ) × 100 <3%, the window decorative sheet is easily peeled off from the window A. When the area S 1 of the flat surface portion 10 and the entire area S 0 are 50% <(S 1 / S 0 ) × 100, the heat insulation is reduced.

図５に示すように、各小凹窪部５に於て小凹窪部５の重心Ｇを通る幅寸法Ｗの平均値Ｗ0 が 0.5mm≦Ｗ0 ≦10mmに設定されている。平均値Ｗ0 がＷ0 ＜ 0.5mmの場合、意匠性が低いとともに、断熱性が小さい。平均値Ｗ0 が10mm＜Ｗ0 の場合、窓用装飾シートが窓Ａから剥がれやすい。 As shown in FIG. 5, the average value W 0 of the width dimension W passing through the center of gravity G of the small concave portion 5 is set to 0.5 mm ≦ W 0 ≦ 10 mm in each small concave portion 5. When the average value W 0 is W 0 <0.5 mm, the design property is low and the heat insulating property is small. When the average value W 0 is 10 mm <W 0 , the window decorative sheet is easily peeled off from the window A.

本発明の窓用装飾シートは、例えば、シート基材１と粘着剤層２と剥離シート３を順次積層した後に、加熱凹凸塑性加工を施してランダム模様凹凸形状Ｅを形成することにより製造することができる。なお、加熱凹凸塑性加工前のシート基材１と粘着剤層２と剥離シート３の積層体の厚さを 150μｍ以下に設定することが望ましい。この場合、容易に加熱凹凸塑性加工を施すことができる。   The decorative sheet for windows of the present invention is manufactured by, for example, sequentially laminating the sheet base material 1, the pressure-sensitive adhesive layer 2, and the release sheet 3, and then performing heating uneven plastic processing to form a random pattern uneven shape E. Can do. In addition, it is desirable to set the thickness of the laminated body of the sheet | seat base material 1, the adhesive layer 2, and the peeling sheet 3 before a heat uneven | corrugated plastic processing to 150 micrometers or less. In this case, heating uneven plastic processing can be easily performed.

本発明は、設計変更可能であって、例えば、ランダム模様凹凸形状Ｅは、上述の条件（正味厚さ寸法等）を満たす範囲で、自由に設定することができる。例えば、図６に示すように、小凹窪部５の周囲（すなわち小凹窪部５と連続陸部６との境界線）形状が、凸部11のみならず凹部12を有するものであっても良い。なお、この場合、小凹窪部５の面積と等しい面積の円の直径を上述の平均値Ｗ0 とみなす。 The design of the present invention can be changed. For example, the random pattern uneven shape E can be freely set within a range satisfying the above-described conditions (such as a net thickness dimension). For example, as shown in FIG. 6, the shape of the periphery of the small concave portion 5 (that is, the boundary line between the small concave portion 5 and the continuous land portion 6) has not only the convex portion 11 but also the concave portion 12. Also good. In this case, the diameter of a circle having an area equal to the area of the small concave depression 5 is regarded as the above average value W 0 .

以上のように、本発明は、シート基材１と粘着剤層２と剥離シート３を順次積層した窓用装飾シートに於て、全ての層に一体的にランダム模様凹凸形状Ｅが形成されており、かつ、剥離シート３を剥離除去した貼着直前状態において、粘着剤層２の露出面４の凹凸形状を、多数の独立状小凹窪部５と、小凹窪部５間に形成された連続陸部６とをもって構成し、さらに、正味厚さ寸法Ｔ0 を50μｍ≦Ｔ0 ≦ 150μｍに設定するとともに、ランダム模様凹凸形状Ｅの表裏各面８，９における深さ寸法Ｈ0 を 150μｍ≦Ｈ0 ≦ 500μｍに設定したので、大きな立体性（高い装飾性、高い意匠性）を付与することができる。また、断熱性が大きく、結露を防止することができる。また、窓Ａとの間にエアーが入って窓用装飾シートが膨らんだ際に、目立つことを防止することができる。 As described above, in the present invention, in the decorative sheet for windows in which the sheet base material 1, the pressure-sensitive adhesive layer 2, and the release sheet 3 are sequentially laminated, the random pattern uneven shape E is integrally formed on all the layers. In addition, in the state immediately before pasting after the release sheet 3 is peeled and removed, the uneven shape of the exposed surface 4 of the pressure-sensitive adhesive layer 2 is formed between a large number of independent small recesses 5 and the small recesses 5. The net thickness dimension T 0 is set to 50 μm ≦ T 0 ≦ 150 μm, and the depth dimension H 0 on the front and back surfaces 8 and 9 of the random pattern uneven shape E is 150 μm. Since it is set to ≦ H 0 ≦ 500 μm, large three-dimensionality (high decorativeness and high designability) can be imparted. Moreover, heat insulation is large and dew condensation can be prevented. Moreover, when air enters between the window A and the window decorative sheet swells, it can be prevented from being noticeable.

また、各小凹窪部５に於て小凹窪部５の重心Ｇを通る幅寸法Ｗの平均値Ｗ0 を 0.5mm≦Ｗ0 ≦10mmに設定したので、意匠性が高く、断熱性が大きい。かつ、窓Ａに対する適度な粘着力を与えることができる。 Moreover, since the average value W 0 of the width dimension W passing through the center of gravity G of the small concave portion 5 is set to 0.5 mm ≦ W 0 ≦ 10 mm in each small concave portion 5, the design is high and the heat insulating property is high. large. And the moderate adhesive force with respect to the window A can be given.

また、粘着剤層２の露出面４の連続陸部６が、同一平面状の平坦面部10を有しているので、窓Ａに容易に貼着することができる。   Moreover, since the continuous land part 6 of the exposed surface 4 of the adhesive layer 2 has the flat surface part 10 of the same plane shape, it can stick to the window A easily.

また、任意の縦断面における各平坦面部10の幅寸法Ｌを 0.1mm≦Ｌ≦７mmに設定したので、意匠性が高く、断熱性が大きい。かつ、窓Ａに対する適度な粘着力を与えることができる。   Moreover, since the width dimension L of each flat surface portion 10 in an arbitrary longitudinal section is set to 0.1 mm ≦ L ≦ 7 mm, the design property is high and the heat insulating property is large. And the moderate adhesive force with respect to the window A can be given.

また、粘着剤層２の平坦面部10の面積Ｓ1 と全体の面積Ｓ0 を３％≦（Ｓ1 ／Ｓ0 ）× 100≦50％を満たすように設定したので、断熱性が大きい。かつ、窓Ａに対する適度な粘着力を与えることができる。 Further, since the area S 1 of the flat surface portion 10 and the entire area S 0 of the pressure-sensitive adhesive layer 2 are set so as to satisfy 3% ≦ (S 1 / S 0 ) × 100 ≦ 50%, the heat insulation is large. And the moderate adhesive force with respect to the window A can be given.

また、シート基材１及び剥離シート３がポリエステルフィルムから成るので、容易に製造することができる。   Moreover, since the sheet | seat base material 1 and the peeling sheet 3 consist of a polyester film, it can manufacture easily.
