されつつある。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a conventional technology relating to a light control film that can be attached to and suitably used on the windows of automobiles. In many cases, a film was uniformly colored over the entire surface in advance to block ultraviolet rays and heat rays. Recently, photochromic inks that change color due to light are also being developed.
発明が解決すべき問題点
このような構成では昼間の紫外線を防止するためには色
を濃くせざるをえず、またフォトクロミックインクを利
用した場合でも変色時は全面に濃くなるようにされてい
る。このように濃くシていくと夜間はもとより昼間にお
いても見えにくく視界が確保出来ない状態となっていた
。Problems to be solved by the invention With such a configuration, the color must be made darker in order to prevent daytime ultraviolet rays, and even when photochromic ink is used, the color becomes darker over the entire surface when the ink changes color. . When the light became darker in this way, it became difficult to see not only at night but also during the day, making it impossible to secure visibility.
それゆえ法律上においても運転席側とフロントウィンド
ウについてはしかいをさまたげるもののはりつけについ
て規制されている。Therefore, the law also restricts the attachment of objects on the driver's seat side and the front window that may obstruct the vehicle.
本発明の目的は構成が簡単でかつフィルムの濃度を必要
に応して設定出来、それゆえ安全な視界を確保する方法
を提供することである。An object of the present invention is to provide a method that is simple in construction, allows the density of the film to be set as required, and thus ensures safe visibility.
問題点を解決するための手段
本発明は日光を調光出来るインク、特にフォトクロミッ
クインクをフィルムに印刷することてその印刷方法によ
り変色時に必要なところのみ濃くなり、他は淡い色に抑
えれることを調節する自動車窓用調光フィルムである。Means for Solving the Problems The present invention prints an ink that can control sunlight, especially a photochromic ink, on a film, and by the printing method, it becomes dark only in the necessary areas when the color changes, and the other areas are kept in a light color. This is a light control film for automobile windows.
作用
本発明に従えば、太陽光の透過を調節するフォトクロミ
ックインクの種類、濃度１重ね印刷の回数などを任意に
選ぶことにより中間時のフィルム濃度の分布パターンを
自由に変えることが出来る。According to the present invention, the distribution pattern of film density at an intermediate time can be freely changed by arbitrarily selecting the type of photochromic ink that adjusts the transmission of sunlight, the number of times of single-density printing, etc.
したがって、前述の調光インクの種類や濃度。Therefore, the type and density of the aforementioned dimming ink.
印刷条件を任意に選ぶことにより、調光フィルムの光に
対する変色を自由にコントロールすることが出来る。By arbitrarily selecting printing conditions, it is possible to freely control the color change of the light control film in response to light.

ォトクロミック粒子は非常に細かく設定されている。Embodiment FIG. 1 is a sectional view of a light control film for automobile windows, which is an embodiment of the present invention. A photochromic ink 2 is uniformly applied to a PET film 1 by gravure printing. The photochromic particles contained in the ink are set very finely so that the photochromic ink side is in contact with the window glass.

とが出来る。FIG. 2 is a perspective view of a light control film 3 for automobile windows, which is another embodiment of the present invention. For pasting, the distribution of photochromic ink is high on the part 4 located above the window.
The lower part 5 can reduce the number of overprints to ensure transparency, adjust the photochromic effect, prevent glare from direct sunlight, and ensure sufficient visibility at night.
このようなインクの塗布状態の密度差を生じさせる他の
方法としては以下の２つの方法がある。There are two other methods for creating such a density difference in the state of ink application as follows.
まず一番目としては、濃度の異なるフォトクロミックイ
ンクを２種用意しておき、これらを使用する印刷箇所を
変えることにより濃淡を得ることが出来る。First, by preparing two types of photochromic inks with different densities and changing the printing locations using these inks, it is possible to obtain different shadings.
もう一方の方法としては、グラビア印刷における版の刻
みこむ深さを変えることにより、その深い箇所では濃く
印刷出来、浅い箇所では薄く印刷することが出来る。こ
のことはフォトクロミックインクを用いて印刷すると変
色時の！淡の差という結果となる。The other method is to change the engraving depth of the plate in gravure printing, so that deep areas can be printed darkly and shallow areas can be printed thinly. This happens when printing with photochromic ink, which causes discoloration! The result is a difference in lightness.
効果
以上のように本発明に従えば、自動車窓用調光フィルム
におけるフォトクロミックインクを用いた印刷を行なえ
ば局部的にインク粒子の布線を変えることにより結果的
に変色時の濃淡とすることが出来る。Effects As described above, according to the present invention, if printing is performed using photochromic ink on a light control film for automobile windows, it is possible to locally change the distribution of ink particles, resulting in the lightness and darkness at the time of discoloration. I can do it.
、従って、昼間は窓の上部が濃く変色して直射日光のま
ぶしさを防ぐが一方下側は透名度を保っているため視界
を確保出来、その結果運転時に支障を生じさせない、こ
のためこのフィルムを前席側窓に装着した場合でも、近
年装着が増加してきているドアーミラーの視認性を妨げ
ることはない。Therefore, during the day, the upper part of the window becomes darkly discolored to prevent glare from direct sunlight, while the lower part maintains transparency, ensuring visibility, and as a result, does not cause any problems when driving. Even when the film is attached to the front seat side window, it does not interfere with the visibility of door mirrors, which have been increasingly installed in recent years.
さらに、変色はフォトクロミックインクによるものであ
るから夜間は透明となりフィルムを装着しない場合とな
んらかわらぬ視認性を確保出来る。Furthermore, since the color change is caused by photochromic ink, it becomes transparent at night, ensuring visibility no different than when no film is attached.
このように本発明による調光フィルムは快適性はさるこ
とながら安全性においても優れたものである。As described above, the light control film according to the present invention is excellent not only in comfort but also in safety.
