Description

本発明は、印刷物及び該印刷物を用いた容器に関する。   The present invention relates to a printed matter and a container using the printed matter.

従来から、各種の印刷物では、その意匠性を向上させるために、金属光沢を付与することが求められる場合がある。   Conventionally, various printed materials may be required to have a metallic luster in order to improve their design properties.

例えば、特許文献1には、紙基材上に、結着樹脂及び金属薄膜細片を含む金属光沢領域層を有する印刷層を形成してなる紙容器が開示されている。
特許文献1の紙容器は、一定レベルの金属光沢を有するものの、印刷により金属光沢を付与するものであるため、高レベルの金属光沢を有するものではなかった。ここで、金属光沢を表現するものとしての「金属光沢感」は、観る角度によって反射強度の急変する度合いによって表現される。
For example, Patent Document 1 discloses a paper container in which a printed layer having a metallic gloss region layer including a binder resin and metal thin film strips is formed on a paper base material.
Although the paper container of Patent Document 1 has a certain level of metallic luster, the paper container imparts metallic luster by printing and thus does not have a high level of metallic luster. Here, the “metallic luster” that expresses the metallic luster is represented by the degree of sudden change in reflection intensity depending on the viewing angle.

一方、高レベルの金属光沢を付与するために、基材上に金属蒸着膜が形成された転写箔を用い、転写箔から印刷物上に金属蒸着膜を転写する手段(いわゆる「箔押し」)も行われている。   On the other hand, in order to give a high level of metallic luster, a transfer foil having a metal vapor deposition film formed on a substrate is used, and means for transferring the metal vapor deposition film from the transfer foil onto the printed material (so-called “foil pressing”) is also provided. It has been broken.

特開2003−2322号公報JP 2003-2322 A

箔押しは、金属蒸着膜を用いるため、高レベルの金属光沢を付与することができる。
しかし、箔押しにより形成した金属蒸着膜は下地の絵柄を完全に隠蔽してしまうため、下地の絵柄(印刷層)と金属蒸着膜とは互いに独立した関係となり、意匠性を十分に高めることができなかった。
Since foil stamping uses a metal vapor deposition film, a high level of metallic luster can be imparted.
However, since the metal vapor deposition film formed by foil stamping completely hides the underlying pattern, the underlying pattern (printing layer) and the metal vapor deposition film are independent of each other, and the design can be sufficiently enhanced. There wasn't.

本発明は、高い金属光沢を有し、意匠性に優れる印刷物及び容器を提供することを目的とする。   An object of this invention is to provide the printed matter and container which have high metallic luster and are excellent in design property.

上記課題を解決するために本発明者らは、まず、ハーフミラー等で用いられている光透過性を有する金属膜について検討を行った。印刷物上に光透過性を有する金属膜を転写した場合、該金属膜を通して下地の印刷を見ることが可能であり、意匠性は向上する。しかし、印刷層の解像度が悪くなることがあり、意匠性が十分ではなかった。
本発明者らはさらに鋭意研究した結果、印刷物からの反射条件を特定のものとすることにより、印刷層の解像度を良好にし、意匠性を十分に発揮することを見出し、本発明を完成するに至った。
In order to solve the above-mentioned problems, the present inventors first examined a light-transmitting metal film used in a half mirror or the like. When a light-transmitting metal film is transferred onto the printed material, it is possible to see the underlying printing through the metal film, and the design is improved. However, the resolution of the printed layer may be deteriorated, and the design properties are not sufficient.
As a result of further diligent research, the present inventors have found that, by making the reflection conditions from the printed matter specific, the resolution of the printed layer is improved and the design properties are sufficiently exhibited, and the present invention is completed. It came.

1/5 value angle ≤ 3.5 degrees (1)
Hereinafter, embodiments of the printed matter of the present invention will be described.

FIG. 1 is a cross-sectional view showing an embodiment of a printed matter 100 of the present invention. The printed matter 100 in FIG. 1 has printed layers 21, 22, 23, 24, 25 and a metal film 40 in this order on the substrate 10. 1 has an adhesive layer 30 between the printed layer and the metal film.

Moreover, although the printed matter 100 of FIG. 1 has the metal film 40 only on the printing layer, the printed film 100 may have the metal film 40 in a place not having the printing layer.

条件(1)
本発明の印刷物は、金属膜側の面に向けて、法線から10度の角度で可視光線を照射した際の正反射方向に対して−45度〜+45度の範囲で0.1度ごとに反射強度を測定し、正反射方向の反射強度の1/5の反射強度を示す拡散角度の絶対値を1/5値角とした際に、金属膜が位置する少なくとも一部の領域において、1/5値角が以下の条件(1)を満たすものである。
1/5値角≦3.5度 (1)
Condition (1)
The printed matter of the present invention is directed to the surface on the metal film side every 0.1 degree in the range of -45 degrees to +45 degrees with respect to the regular reflection direction when irradiated with visible light at an angle of 10 degrees from the normal. When the reflection intensity is measured and the absolute value of the diffusion angle indicating the reflection intensity of 1/5 of the reflection intensity in the regular reflection direction is set to a 1/5 value angle, in at least a part of the region where the metal film is located, The 1/5 value angle satisfies the following condition (1).
1/5 value angle ≤ 3.5 degrees (1)

「1/5値角」が意味するものを説明する。
1/5値角の基準となる「正反射方向の反射強度」は、印刷物に入射し、反射する光のうち、正反射方向(入射光を+10度とした場合、−10度の方向)に反射する光の強度を示している。つまり、正反射方向の反射強度は、金属膜の表面、印刷層の表面、基材の表面及びこれらの層の内部で拡散されることなく、正反射方向に反射された光の強度である。また、正反射方向の反射強度は、金属膜の表面平滑箇所、印刷層の表面平滑箇所及び基材の表面平滑箇所で正反射された光の強度ともいえる。
一方、1/5値角は、印刷物に入射し、反射する光のうち、拡散反射した光が広がる範囲を示している。より具体的には、1/5値角は拡散による反射光が広がる範囲を示している。したがって、1/5値角を示す条件(1)を満たすことは、拡散が過度ではないことを意味している。
What is meant by “1/5 value angle” will be described.
The “reflection intensity in the regular reflection direction”, which is the reference for the 1/5 value angle, is the regular reflection direction (in the direction of −10 degrees when the incident light is +10 degrees) out of the light that enters and reflects the printed matter. It shows the intensity of the reflected light. That is, the reflection intensity in the regular reflection direction is the intensity of light reflected in the regular reflection direction without being diffused on the surface of the metal film, the surface of the printing layer, the surface of the base material, and the inside of these layers. The reflection intensity in the regular reflection direction can also be said to be the intensity of light regularly reflected at the surface smooth spot of the metal film, the surface smooth spot of the printing layer, and the surface smooth spot of the substrate.
On the other hand, the 1/5 value angle indicates a range in which diffusely reflected light spreads out of light incident on and reflected by the printed matter. More specifically, the 1/5 value angle indicates a range in which reflected light due to diffusion spreads. Therefore, satisfying the condition (1) indicating the 1/5 value angle means that the diffusion is not excessive.

上述したように、条件(1)を満たすことは、拡散が少ないことを意味し、拡散が少ないために解像度が良好となり、印刷物の意匠性を向上させることができる。また、1/5値角が小さ過ぎる場合、拡散が殆どなく、後述する光輝感が低下する傾向がある。このため、条件(1)は、2.0度≦1/5値角≦3.5度を満たすことが好ましく、2.5度≦1/5値角≦3.2度を満たすことがより好ましい。   As described above, satisfying the condition (1) means that the diffusion is small, and since the diffusion is small, the resolution becomes good and the design of the printed matter can be improved. On the other hand, when the 1/5 value angle is too small, there is almost no diffusion and the glitter feeling described later tends to decrease. Therefore, the condition (1) preferably satisfies 2.0 degrees ≦ 1/5 value angle ≦ 3.5 degrees, and more preferably satisfies 2.5 degrees ≦ 1/5 value angle ≦ 3.2 degrees. preferable.

条件(1)は、金属膜が位置する少なくとも一部の領域において満たしていればよい。また、本発明の効果をより良好にするためには、金属膜が位置する全ての領域において、条件(1)を満たすことが好ましい。   Condition (1) only needs to be satisfied in at least a part of the region where the metal film is located. In order to improve the effect of the present invention, it is preferable that the condition (1) is satisfied in all regions where the metal film is located.

条件(2)
本発明の印刷物は、金属膜が位置する少なくとも一部の領域において、正反射方向の前後3度における反射強度の平均値を、正反射方向の反射強度で除した値を光輝感値とし、光輝感値が以下の条件(2)を満たすことが好ましい。
0.05≦光輝感値 (2)
Condition (2)
In the printed matter of the present invention, in at least a part of the region where the metal film is located, the value obtained by dividing the average value of the reflection intensity at 3 degrees before and after the regular reflection direction by the reflection intensity in the regular reflection direction is used as the glitter value. It is preferable that the sensitivity value satisfies the following condition (2).
0.05 ≤ brightness value (2)

「光輝感値」が意味するものを説明する。
光輝感値の基準となる「正反射方向の前後3度における反射強度の平均値」は、印刷物に入射し、反射する光のうち、正反射方向の前後3度(入射光を+10度、正反射光を−10度とした場合、−7度及び−13度)における反射する光の強度の平均値を示している。人間は無意識のうちに、正反射光を除いて物を観察する習性がある。このため、人間が感じる印刷物の金属調等の光り輝きの程度(光輝感)は、正反射方向の近傍の反射強度が重要となる。光輝感を高めるには正反射方向の前後3度以内の反射強度が重要となる。特に正反射方向の前後3度の反射強度が重要となる(前後3度の反射強度が高ければ、前後3未満の反射強度はさらに高い値を示す。)。しかし、正反射方向の反射強度よりも、正反射方向の前後3度の反射強度が小さ過ぎると、コントラストの関係から光輝感が感じられにくくなる。このため、正反射方向の前後3度の反射強度の平均値と正反射方向の反射強度との比(光輝感値)が一定範囲であることにより、人間にとって好適な光輝感を有する印刷物となる。
「正反射方向の反射強度」は、上述したように、印刷物に入射し、反射する光のうち、正反射方向に反射する光の強度を示している。
以上より、「光輝感値」は、光輝感を示す光の強度を正反射方向に反射する光の強度で除することにより、光輝感を示す光の強度を相対値として示したものである。
What is meant by “shininess value” will be described.
The “average value of the reflection intensity at 3 degrees before and after the regular reflection direction”, which is a reference for the glitter value, is 3 degrees before and after the regular reflection direction of incident light that is incident on the printed matter (+10 degrees incident light is positive When the reflected light is −10 degrees, the average value of the intensity of the reflected light at −7 degrees and −13 degrees is shown. Humans unconsciously have the habit of observing objects except for regular reflection light. For this reason, the reflection intensity in the vicinity of the regular reflection direction is important for the degree of brightness (shininess) such as the metallic tone of printed matter that humans feel. In order to enhance the glitter, the reflection intensity within 3 degrees before and after the regular reflection direction is important. In particular, the reflection intensity of 3 degrees before and after in the regular reflection direction is important (if the reflection intensity at 3 degrees before and after is high, the reflection intensity below 3 before and after shows a higher value). However, if the reflection intensity at 3 degrees before and after the regular reflection direction is less than the reflection intensity in the regular reflection direction, it is difficult to feel the glitter due to the contrast. For this reason, the ratio of the average reflection intensity of 3 degrees before and after the regular reflection direction and the reflection intensity in the regular reflection direction (the glitter value) is within a certain range, so that the printed matter has a glitter feeling suitable for humans. .
As described above, the “reflection intensity in the regular reflection direction” indicates the intensity of light that is incident on the printed matter and reflected in the regular reflection direction.
As described above, the “luminosity value” is obtained by dividing the intensity of light exhibiting glitter feeling by the intensity of light reflected in the regular reflection direction, thereby indicating the intensity of light exhibiting glitter feeling as a relative value.

条件(2)を満たすことにより、光輝感を付与することができ、印刷物の意匠性を向上させることができる。
なお、光輝感値が大きすぎると、光輝感に注意が削がれて下地が見えにくくなる傾向にある。このため、条件(2)は、0.05≦光輝感値≦0.70を満たすことが好ましく、0.07≦光輝感値≦0.50を満たすことがより好ましく、0.10≦光輝感値≦0.30を満たすことがさらに好ましい。
By satisfying the condition (2), a glittering feeling can be imparted and the design of the printed matter can be improved.
Note that if the glitter value is too large, attention is lost to the glitter feeling and the background tends to be difficult to see. Therefore, the condition (2) preferably satisfies 0.05 ≦ brightness value ≦ 0.70, more preferably satisfies 0.07 ≦ brightness value ≦ 0.50, and 0.10 ≦ brightness. It is more preferable to satisfy the value ≦ 0.30.

反射強度の測定方法
まず、印刷物の金属膜側の面に向けて、法線から10度の角度で可視光線を照射する。そして、反射した光について、正反射方向に対して−45度〜+45度の範囲で0.1度ごとに受光器を走査して、各角度での強度(光度)を測定する。強度測定の際は光源の明るさを一定とする。また、強度(光度)測定の際は、受光器の絞りにより検出する受光器の開口角を0.1度とする。このため、例えば、正反射方向(0度)の測定では±0.05度の範囲を測定し、+1度の測定では0.95度〜1.05度の範囲を測定し、−1度の測定では−0.95度〜−1.05度の範囲を測定することになる。
強度を測定する装置については、特に制限はなく、汎用の変角光度計(ゴニオフォトメーター)を用いることができる。本発明においては、変角光度計として、村上色彩技術研究所社製の商品名GP−200(光束径:約10.5mm、光束内傾斜角:0.29度以内)を使用した。
Measurement Method of Reflection Intensity First, visible light is irradiated at an angle of 10 degrees from the normal line toward the surface of the printed material on the metal film side. And about the reflected light, a light receiver is scanned every 0.1 degree in the range of -45 degree- + 45 degree with respect to a regular reflection direction, and the intensity | strength (luminous intensity) in each angle is measured. When measuring the intensity, the brightness of the light source is constant. When measuring the intensity (luminous intensity), the aperture angle of the light receiver detected by the diaphragm of the light receiver is set to 0.1 degree. For this reason, for example, a range of ± 0.05 degrees is measured in the regular reflection direction (0 degree), a range of 0.95 to 1.05 degrees is measured in the measurement of +1 degree, and a range of −1 degree is measured. In the measurement, a range of −0.95 degrees to −1.05 degrees is measured.
There is no restriction | limiting in particular about the apparatus which measures intensity | strength, A general purpose goniophotometer (goniophotometer) can be used. In the present invention, a trade name GP-200 (light beam diameter: about 10.5 mm, tilt angle within light beam: within 0.29 degrees) manufactured by Murakami Color Research Laboratory Co., Ltd. was used as a goniophotometer.

1/5値角の算出
1/5値角は、上述のように測定した反射強度から算出できる。具体的には、まず、正反射方向の反射強度(正反射強度)の値を確認する。1/5値角を算出する場合は、正反射強度の1/5以下となる測定角度を、プラス方向及びマイナス方向の双方で確認し、該角度の絶対値の平均値を1/5値角とする。このように、1/5値角は、反射強度の実測値から算出できる。なお、反射強度分布図を用いて1/5値角の概算値を知ることもできる。
なお、正反射方向の測定角度が10度から大きく離れると、反射強度が漸減することなく上下動する場合がある。この場合、正反射強度の1/5以下に落ちた後、1/5を越し、再度1/5以下に落ちることがある。このように、正反射強度の1/5以下となる測定角度が複数観察される場合、1/5以下となる測定角度は、最初に現れる測定角度と、最後に現れる測定角度との中間値とする。
Calculation of 1/5 value angle The 1/5 value angle can be calculated from the reflection intensity measured as described above. Specifically, first, the value of the reflection intensity (regular reflection intensity) in the regular reflection direction is confirmed. When calculating the 1/5 value angle, check the measurement angle that is 1/5 or less of the regular reflection intensity in both the positive and negative directions, and calculate the average of the absolute values of the angle as the 1/5 value angle. And Thus, the 1/5 value angle can be calculated from the actually measured value of the reflection intensity. An approximate value of the 1/5 value angle can also be obtained using the reflection intensity distribution diagram.
When the measurement angle in the regular reflection direction is far from 10 degrees, the reflection intensity may move up and down without gradually decreasing. In this case, after falling to 1/5 or less of the regular reflection intensity, it may exceed 1/5 and fall to 1/5 or less again. Thus, when multiple measurement angles that are 1/5 or less of the specular reflection intensity are observed, the measurement angle that is 1/5 or less is an intermediate value between the measurement angle that appears first and the measurement angle that appears last. To do.

光輝感値の算出
光輝感値は、上述のように測定した反射強度から算出できる。具体的には、まず、正反射方向(入射光を+10度とした場合、−10度の方向)の反射強度(正反射強度)の値を確認する。次いで、正反射方向の前後3度(入射光を+10度、正反射光を−10度とした場合、−7度及び−13度)の値を確認し、それらの反射強度の平均値を算出する。次いで、正反射方向の前後3度の反射強度の平均値を正反射強度で除して、光輝感値を算出する。
Calculation of glitter value The glitter value can be calculated from the reflection intensity measured as described above. Specifically, first, the value of the reflection intensity (regular reflection intensity) in the regular reflection direction (in the direction of −10 degrees when incident light is +10 degrees) is confirmed. Next, confirm the value of 3 degrees before and after the regular reflection direction (-7 degrees and -13 degrees when the incident light is +10 degrees and the regular reflection light is -10 degrees), and calculate the average value of the reflection intensity. To do. Next, the brightness value is calculated by dividing the average value of the reflection intensity of 3 degrees before and after the regular reflection direction by the regular reflection intensity.

基材
基材は、基材表面のカットオフ値0.8mmのJIS B0601:2001の算術平均粗さRaが1.0μm以下のものを用いることが好ましい。
基材表面のRaを1.0μm以下とすることにより、拡散を抑制し、印刷物の解像度の低下を抑制することができる。
また、光透過性を有する金属膜の厚みムラに基づく金属光沢感のムラを解消する観点から、基材表面のRaは、0.3μm以上であることが好ましい。基材表面のRaは、0.4〜0.9μmであることがより好ましい。
なお、基材として平滑な基材を用い、印刷層を形成するインキにマット剤を含有させることにより、金属膜の表面を凹凸化することも考えられる。しかし、該構成ではマット剤により形成された凹凸が十分に緩和されることなく金属膜に反映される場合があり、その結果、金属膜の表面が過度に凹凸化され、金属光沢感が低下したり、凹凸感が目立ちすぎたりするため好ましくない。
Base material It is preferable to use a base material whose arithmetic mean roughness Ra of JIS B0601: 2001 having a cutoff value of 0.8 mm on the surface of the base material is 1.0 μm or less.
By setting the Ra of the substrate surface to 1.0 μm or less, diffusion can be suppressed and a decrease in resolution of the printed matter can be suppressed.
In addition, from the viewpoint of eliminating the unevenness of the metallic luster based on the unevenness of the thickness of the light-transmitting metal film, the Ra of the substrate surface is preferably 0.3 μm or more. Ra of the substrate surface is more preferably 0.4 to 0.9 μm.
It is also conceivable to make the surface of the metal film uneven by using a smooth base material as a base material and adding a matting agent to the ink forming the print layer. However, in this configuration, the unevenness formed by the matting agent may be reflected in the metal film without being sufficiently relaxed, and as a result, the surface of the metal film is excessively uneven, and the metallic luster is lowered. Or the unevenness is too conspicuous.

基材の材料は、例えば、上質紙、中質紙、コート紙、合成紙、含浸紙、ラミネート紙、印刷用塗布紙、記録用塗布紙等の紙、ポリエチレンテレフタレートフィルム、ポリエチレンフィルム、ポリプロピレンフィルム、ポリカーボネートフィルム等のプラスチックフィルム、あるいはこれらの複合体等が用いられる。
基材は、紙、プラスチックフィルムあるいはこれらの複合体等の基体に対して、サンドブラスト、ケミカルエッチング等の物理的処理や化学的処理を施すことによって、表面のRaを上記範囲に調整したものでもよい。また、基材は、紙、プラスチックフィルムあるいはこれらの複合体等の基体に対して、プライマー層を形成することによって、表面のRaを上記範囲に調整したものでもよい。
The material of the base material is, for example, high-quality paper, medium-quality paper, coated paper, synthetic paper, impregnated paper, laminated paper, printing coated paper, paper for recording, etc., polyethylene terephthalate film, polyethylene film, polypropylene film, A plastic film such as a polycarbonate film, or a composite of these is used.
The substrate may have a surface Ra adjusted to the above range by subjecting a substrate such as paper, plastic film, or a composite thereof to physical or chemical treatment such as sandblasting or chemical etching. . In addition, the substrate may be a substrate whose surface Ra is adjusted to the above range by forming a primer layer on a substrate such as paper, plastic film or a composite thereof.

基材の表面は、カットオフ値0.8mmのJIS B0601:2001の粗さ曲線の最大山高さRpが10.0μm以下であることが好ましく、8.0μm以下であることがより好ましく、1.0〜7.0μmであることがさらに好ましい。
基材表面のRpが10.0μm以下であることは、基材表面に極端に高い凸部がなく、基材表面の粗さが平均化されていることを意味する。このため、基材表面のRpを10.0μm以下とすることにより、金属光沢感のムラをより解消しやすくできる。
As for the surface of a base material, it is preferable that the maximum peak height Rp of the roughness curve of JIS B0601: 2001 with a cutoff value of 0.8 mm is 10.0 micrometers or less, It is more preferable that it is 8.0 micrometers or less. More preferably, it is 0-7.0 micrometers.
That the Rp of the substrate surface is 10.0 μm or less means that there is no extremely high convex portion on the substrate surface, and the roughness of the substrate surface is averaged. For this reason, by setting the Rp of the substrate surface to 10.0 μm or less, it is possible to more easily eliminate the unevenness of the metallic gloss.

基材の厚みは特に限定されないが、紙基材の場合は、通常は坪量150〜550g/m程度であり、プラスチックフィルム基材の場合は、通常は9〜50μm程度である。 The thickness of the substrate is not particularly limited, but in the case of a paper substrate, the basis weight is usually about 150 to 550 g / m 2 , and in the case of a plastic film substrate, it is usually about 9 to 50 μm.

金属膜の全光線透過率は、30〜60%であることが好ましく、40〜55%であることがより好ましく、45〜50%であることがさらに好ましい。
なお、本発明において、金属膜の全光線透過率は、下記サンプルの20箇所で全光線透過率を測定した際の平均値とする。
(サンプル)
厚み1mmのソーダ石灰ガラス(屈折率1.51)上に、厚み1.5μmの接着剤層(屈折率1.51)を介して金属膜を形成したもの。
In the present invention, a metal film having a total light transmittance of 20 to 80% according to JIS K7361-1: 1997 is used as the metal film.
When the total light transmittance of the metal film is less than 20%, it becomes difficult to see through the pattern of the printed layer, and the design property cannot be improved. Moreover, when the total light transmittance of a metal film exceeds 80%, the reflectance of a metal film will fall and metal glossiness will fall.
The total light transmittance of the metal film is preferably 30 to 60%, more preferably 40 to 55%, and still more preferably 45 to 50%.
In addition, in this invention, let the total light transmittance of a metal film be an average value at the time of measuring total light transmittance in 20 places of the following sample.
(sample)
A metal film formed on a 1 mm thick soda-lime glass (refractive index 1.51) via an adhesive layer (refractive index 1.51) having a thickness of 1.5 μm.

全光線透過率が20〜80%の金属膜は、光透過性を有するため厚みが薄い。そして、厚みが薄い金属膜は、僅かな厚みムラがあっても、該厚みムラを原因として、金属光沢感にムラが生じやすい。このため、基材としてRaが0.3μm以上のものを用いて、金属光沢感のムラを解消することが好ましい。   A metal film having a total light transmittance of 20 to 80% is thin because it has light transmittance. And even if there is slight thickness unevenness, a metal film with a small thickness tends to cause unevenness in the metallic luster due to the thickness unevenness. For this reason, it is preferable to use a substrate having an Ra of 0.3 μm or more to eliminate unevenness of the metallic luster.

上述した厚みムラは、例えば、金属膜の全光線透過率の標準偏差で表すことができる。具体的には、全光線透過率が20〜80%の金属膜の任意の20箇所のJIS K7361−1:1997の全光線透過率の標準偏差は、通常0.02〜0.10%程度である。   The thickness unevenness described above can be expressed by, for example, the standard deviation of the total light transmittance of the metal film. Specifically, the standard deviation of the total light transmittance of JIS K7361-1: 1997 at any 20 locations of a metal film having a total light transmittance of 20 to 80% is usually about 0.02 to 0.10%. is there.

金属膜は、アルミニウム、銀、金、ニッケル、銅、クロム等の金属の一種又は二種以上から形成される。これらの中でも、色味が少ないアルミニウム、銀、ニッケルが好ましく、特にアルミニウムがより好ましい。   The metal film is formed of one or more metals such as aluminum, silver, gold, nickel, copper, and chromium. Among these, aluminum, silver, and nickel having a small color are preferable, and aluminum is more preferable.

金属膜は、例えば、転写箔の金属膜を印刷層上に転写することにより形成することができる。
転写箔は、例えば、ベースフィルム上に、離型層、金属膜及び接着剤層を有する構成からなる。
The metal film can be formed, for example, by transferring the metal film of the transfer foil onto the printing layer.
Transfer foil consists of a structure which has a mold release layer, a metal film, and an adhesive bond layer on a base film, for example.

ベースフィルムは汎用のプラスチックフィルムを用いることができる。ベースフィルムの厚みは5〜30μm程度である。   A general-purpose plastic film can be used as the base film. The thickness of the base film is about 5 to 30 μm.

離型層は、転写時にベースフィルムに残ってもよいし、金属膜及び接着剤層とともに印刷物側に転写されてもよい。
転写時にベースフィルムに残る離型層は、離型効果のみを発揮し、シリコーン系離型剤、オレフィン系離型剤等の汎用の離型剤から形成することができる。
転写時に印刷物側に転写される離型層は、転写後は金属膜上に位置し、金属膜を保護する保護層としての機能を有する。かかる保護機能を有する離型層(保護層)は、硬化型の樹脂の硬化物、あるいは金属酸化物膜であることが好ましい。硬化型の樹脂としては、汎用の熱硬化型樹脂、電離放射線硬化型樹脂を用いることができる。金属酸化物膜としては、シリカ、アルミナ等の透明金属酸化物膜が挙げられる。
離型層の厚みは、離型層のタイプにより異なるため一概にはいえない。転写時にベースフィルムに残る離型層の場合、厚みは特に限定されないが、通常0.1〜1.0μm程度である。転写時に印刷物側に転写される離型層(保護層)の場合、金属膜を保護する観点、及び金属膜表面の粗さを離型層(保護層)上でも維持する観点から、0.02〜1.0μmであることが好ましく、0.03〜0.5μmであることがより好ましい。
The release layer may remain on the base film at the time of transfer, or may be transferred to the printed material side together with the metal film and the adhesive layer.
The release layer remaining on the base film at the time of transfer exhibits only a release effect and can be formed from a general-purpose release agent such as a silicone release agent or an olefin release agent.
The release layer transferred to the printed material side at the time of transfer is located on the metal film after the transfer, and has a function as a protective layer for protecting the metal film. The release layer (protective layer) having such a protective function is preferably a cured product of a curable resin or a metal oxide film. As the curable resin, a general-purpose thermosetting resin or ionizing radiation curable resin can be used. Examples of the metal oxide film include transparent metal oxide films such as silica and alumina.
Since the thickness of the release layer varies depending on the type of the release layer, it cannot be said unconditionally. In the case of the release layer remaining on the base film at the time of transfer, the thickness is not particularly limited, but is usually about 0.1 to 1.0 μm. In the case of a release layer (protective layer) transferred to the printed material side at the time of transfer, from the viewpoint of protecting the metal film and maintaining the roughness of the metal film surface also on the release layer (protective layer), 0.02 It is preferable that it is -1.0 micrometer, and it is more preferable that it is 0.03-0.5 micrometer.

転写箔の接着剤層は、上述した接着剤層と同様の構成が挙げられる。接着剤層を構成する接着剤がホットメルト型接着剤の場合、金属膜等は熱転写方式で転写できる。また、接着剤層を構成する接着剤が感圧型接着剤の場合、金属膜等はコールド転写法式で転写できる。   The adhesive foil of the transfer foil has the same configuration as the adhesive layer described above. When the adhesive constituting the adhesive layer is a hot melt adhesive, the metal film or the like can be transferred by a thermal transfer method. When the adhesive constituting the adhesive layer is a pressure sensitive adhesive, the metal film or the like can be transferred by a cold transfer method.

金属膜上には、本発明の効果を阻害しない範囲で、着色層等の機能層を有していてもよい。   On the metal film, you may have functional layers, such as a colored layer, in the range which does not inhibit the effect of this invention.
