Description

The present invention relates to a technique for blocking or cutting “miscellaneous light” such as reflected light, which functions as a film adhered to a substrate that transmits visible light, such as a windshield of an automobile, or the substrate itself.

  During the day, while driving a car, objects placed on the dashboard may be reflected on the inner surface of the windshield. In addition, the reflection of sunlight with strong sunlight on the road surface may obstruct the driver's original view. As a means for preventing such light that causes an unnecessary image that is visually disturbing from the viewpoint of safe driving for the driver (hereinafter referred to as “miscellaneous light”), a miscellaneous light cut filter (polarizing filter). It has been proposed to wear "sunglasses" that are sandwiched between two lenses, and the sunglasses have been put to practical use. Such sunglasses block sunlight reflections from the road surface during the day or sunlight from the ground or sea surface during outdoor activities such as sports or fishing during the day. It is effective in securing a good field of view (see Non-Patent Document 1).

  By the way, when driving in the sun at night when the sun goes down, it is combined with the wiper operation. 1) The light from the lighting tower beside the road, neon light, or the headlight light from the oncoming vehicle is miscellaneous. Since the rainwater is collected or reflected on the road surface of the road wetted by the rainwater to make the driver in the vehicle visually recognize the glare, the driver is in a situation that requires careful driving. In addition, 2) the headlight light of the oncoming vehicle or the headlight light of the following vehicle (especially in the case of a subsequent vehicle having a higher vehicle height than the host vehicle), the amount of miscellaneous light increases as the miscellaneous light. The driver's field of view through the windshield or rear glass and the rearview mirror will be less clear than during the day when driving directly into the eyes. It is in the situation.

  In driving a car under such a rainy condition at night, wearing the above-mentioned “sunglasses” is not preferable as a solution because the driver's field of vision becomes darker.

  The above-mentioned problem of miscellaneous light occurs to a greater or lesser extent even at nighttime when it is not raining.

  Further, the above-mentioned deterioration of the visibility due to the miscellaneous light occurs not only when driving a car, but also when driving and maneuvering other “vehicles” such as motorcycles, buses, airplanes and helicopters.

  Moreover, although the story is not “vehicles”, the deterioration of the field of view due to the above-mentioned “noisy light” (reflection), which is an obstacle to the realization of a good human field of view, is from inside the building or the like to the outside through the window. The same is true in terms of deteriorating visibility. In such a case, wearing “sunglasses” for a long time indoors is not preferable because it causes tired eyes.

The present invention has been made in view of the above-mentioned problems, and its main purpose is to propose the realization of a substrate adhesive film or substrate capable of suppressing “noisy light” that causes deterioration of visibility. There is.

  The first subject of the present invention is a miscellaneous light cut film for substrate adhesion, which is adhered to the surface of a substrate made of either glass or synthetic resin that transmits visible light, and the first surface. A first film having a second surface opposed to the first film and transmitting visible light; a third surface facing the second surface of the first film; and facing the third surface and transmitting visible light. A second film having a fourth surface that is not adhered to the substrate to be transmitted and transmitting visible light; the second surface of the first film; and the third surface of the second film; A polarization filter that does not transmit a component of light that is visible to human vision as miscellaneous light in the light, but transmits other components of the incident visible light.

  A second subject matter of the present invention is a miscellaneous light-cutting substrate, which is comprised of either a glass or a synthetic resin that transmits visible light, and is included in the substrate. A polarizing filter that transmits other visible light components while not transmitting light components that are visible as miscellaneous light to human vision among the incident visible light.

  According to the first and second of the subject matter of the present invention, for example, it is possible to suppress the incident on the eyes of other light such as reflected light shining due to rain water on the road surface at night when it rains, and to reduce the original field of view without any light. It can be made visible to the eyes. As a result, the visual recognition level of reflected light or reflected light that is dazzling to the eyes is remarkably reduced.

  Hereinafter, various embodiments of the present invention will be described in detail along with the effects and advantages thereof with reference to the accompanying drawings.

<Structure of miscellaneous light cut film for substrate adhesion>

  FIG. 1 is a perspective view schematically showing a configuration of a miscellaneous light cut film 10 for substrate adhesion according to the present embodiment. As shown in FIG. 1, the miscellaneous light-cutting film 10 for substrate adhesion is basically composed of a first film 1, a polarizing filter 3, and a second film 2.

The first film 1 transmits visible light (the transmittance is not limited to a specific value) and is a colorless and transparent or colored “substrate” (not shown) made of either glass or synthetic resin (plastic or the like). A multilayer film attached to the surface of That is, the first film 1 has a first surface SA that is adhered to one surface of the substrate using an adhesive, and a second surface SB that is entirely opposed to the first surface SA. For example, the first film 1 is made of, as a main material, a synthetic resin such as a plastic film, more specifically PP (polypropylene), PE (polyethylene) using abbreviated symbols.
(polyethylene)), PC (polycarbonate), PET (polyethylene terephthalate), OPCP, or the like. Typically, polyethylene (PE) is used as the material of the first film 1.

  The second film 2 is a multilayer film having a third surface SE facing the second surface SB of the first film 1 and a fourth surface SF entirely facing the third surface SE. Similar to the first film 1, the second film 2 is made of, for example, a synthetic resin such as a plastic film as a main material, and more specifically using abbreviated symbols such as PP, PE, PC, PET, OPCP, etc. Made of any material. Similarly, polyethylene (PE) is typically used as the material of the second film 2. Note that, unlike the first surface SA, the fourth surface SF is not adhered to a substrate that transmits visible light.

  Furthermore, the polarizing filter 3 is sandwiched between the second surface SB of the first film 1 and the third surface SF of the second film 2 in a close contact state. That is, each of the one main surface SC of the polarizing filter 3 and the other opposing main surface SD are in close contact with the second surface SB of the first film 1 and the third surface SF of the second film 2. The polarizing filter 3 is made of a known commercially available material and has the same action and effect as a polarizing (PL) filter attached to a camera lens. That is, the polarizing filter 3 is a component of light that is visually recognized as “miscellaneous light” for human vision among the visible light incident on the substrate due to the polarization action (reflection on a water surface, a glass surface, a plastic surface, or the like). Light, the reflected light from the road surface of sunlight, the headlight light of the oncoming vehicle during driving or the succeeding vehicle when the signal is stopped, etc.) are blocked and transmitted. As a result, a person such as a driver can visually recognize the original field of view as a result of removing the “slight light”. The polarizing filter 3 may be colored.

  FIG. 2 is a view schematically showing an example of a multilayer structure of the miscellaneous light-cutting film 10 for substrate adhesion shown in FIG. 1. For example, the film 10 is composed of six layers of film by coating or the like. In FIG. 2, for convenience of illustration, each film or polarizing filter is illustrated as being separated from each other, and the polarizing filter 3 is hatched.

In FIG. 2, the 1st film 1 consists of a film of 3 layers of the film 1A for adhesion to a board | substrate, the coating film 1B for damage prevention, and the UV (ultraviolet rays) cut film 1C as an example. The number of layers and the arrangement order of the films constituting the first film 1 are arbitrary. Moreover, the 2nd film 2 which sandwiches the polarizing filter 3 with the 1st filter 1 consists of a film of 2 layers, as an example, the UV cut film 2A and the coating film 2B for damage prevention inside. Similarly, the number of layers and the arrangement order of the second film 2 are arbitrary. The thickness of the miscellaneous light-cutting film 10 for substrate adhesion shown in FIG. 2 is a value in the range of 25 μm to 28 μm, for example. Further, as the degree of coloring of the polarizing filter 3 increases, the function of the polarizing filter 3 as a “miscellaneous light cut filter” increases.

<Application examples of miscellaneous light cut film for substrate adhesion to various "substrates">

1) Adhering the substrate adhesive miscellaneous light cut film 10 illustrated in FIG. 1 to one surface of each window glass or various mirrors (each corresponding to a “substrate”) of an automobile. With this application, the reflected light that shines brilliantly, the reflection of objects on the window glass, etc., or the “light” of the headlights of the following vehicles, etc. are blocked, and the driver has a clear view, that is, the view that should be originally intended Etc. can be visually recognized. An example of application to such a four-wheeled vehicle is schematically shown in FIG.

  For example, in FIG. 3, the substrate light miscellaneous light cut film 10 is adhered to the back surface of the windshield FG of the automobile. With this configuration, a car film having a miscellaneous light cutting function is realized. As a result, the headlights of the oncoming vehicle can be used not only during the daytime or at night, but also when it is raining. The polarizing filter 3 blocks the dazzling “miscellaneous light” in which light such as illumination light is reflected on the road surface and shines shiningly, and does not transmit the light into the vehicle.

Alternatively, the substrate light miscellaneous light cut film 10 is adhered on the back surface of the side glass DG on the driver's seat side of the automobile or on the back surface of the side glass AG on the passenger seat side. Also with this configuration, the car film having the above-described miscellaneous light cutting function is realized with respect to the side window glass. In other words, the polarizing filter 3 blocks “miscellaneous light” that is incident from the window glass on each side surface of the automobile, and does not transmit “miscellaneous light” into the vehicle. As a result, in combination with the adhesion of the plate light miscellaneous light-cutting film 10 to the windshield FG, further “blocking” of “light” is realized, and the driver's view during driving is further cleared. It becomes.

Or, the rear light glass RSG on both sides of the rear seat side of the automobile or the inner surface of each glass of the rear glass RG may be adhered to the miscellaneous light cut film 10 for substrate adhesion, and in these application examples, It is possible to obtain an effect of blocking “miscellaneous light” such as reflected light that glitters, reflected light from the face, etc., or a headlight of a subsequent vehicle when the vehicle stops due to a red signal or traffic jam.

Alternatively, the substrate light miscellaneous light cut film 10 is adhered on the glass surface of a room mirror and / or a door mirror or a fender mirror in an automobile, for example, dazzling from a following vehicle in a traffic jam or waiting for a signal. The reflection of the headlight can be reduced. That is, the luminous flux of the headlight of a dazzling subsequent vehicle that has passed through the adhered substrate adhesive miscellaneous light cut film 10 and reflected on the glass surface of each of the mirrors, and then entered the substrate adhesive miscellaneous light cut film 10 again. Is blocked by the polarizing filter 3 due to the polarized light generated upon reflection on the glass surface. As a result, the amount of light of the headlight transmitted from the miscellaneous light-cutting film 10 for substrate adhesion toward the inside of the vehicle is significantly reduced. Therefore, the driver is not bothered by the poor visibility due to “miscellaneous light” such as the reflected light of the headlight of the succeeding vehicle reflected on each mirror during driving, and can see a clear view.

Or a screen (glass surface) of a television display (corresponding to a “board”) provided in an automobile, various devices provided in front of the driver's seat, such as a car navigation system, a monitor, a tachometer, and a speedometer Adhering the substrate light miscellaneous light cut film 10 on the glass surface of the panel (corresponding to “substrate”), for example, the “miscellaneous” of dazzling headlights from the following vehicles in a traffic jam or waiting for a signal. It may be possible to block the light and secure a clear view.

Alternatively, other “vehicles” such as airplanes, helicopters, railway cars, buses, motorcycles, etc. on the cockpit side or passenger side windows or plastic surfaces (synthetic resin surfaces) (on the “substrate”) Applicable)) may be adhered on the inner surface of the substrate adhesive, and the above-mentioned various “slight light” may be blocked by the same action of the film 10 to achieve a clear visual field.

2) Or on the inner surface of a residential window glass (corresponding to a “substrate”) in a house such as a detached house or an apartment, or in a glass of a building such as a building (corresponding to a “substrate”). Adhering the substrate 10 on the inner surface of the half mirror, the substrate 10 miscellaneous light cut film blocks the above-mentioned various “irregular light” by the action of the film 10 and realizes a clear view from the indoor side. You may do it.

3) Or, by attaching the miscellaneous light cut film 10 for substrate adhesion on the surface of the glass (corresponding to “substrate”) of the corner mirror disposed at the corner of the road, the above various “ It is also possible to block the “miscellaneous light” and make the driver's field of view a clear view without the influence of the “unusual light”.

4) In addition, for adhesion to substrates on glass films (corresponding to “substrate”) of liquid crystal / organic EL screens of various terminals such as mobile phones, multi-function phones, tablet terminals, PDAs, etc. The miscellaneous light cut film 10 may be adhered to similarly block the above-mentioned various “miscellaneous light”. Or, attach the substrate light miscellaneous light cut film 10 on the glass (corresponding to “substrate”) that forms the screen of various OA devices (computers, monitors, multifunction devices, fax machines, copiers, etc.). Similarly, a clear screen may be ensured by blocking the various “lights” described above. Alternatively, a clear screen may be secured by adhering the miscellaneous light-cutting film 10 for substrate adhesion on the glass (corresponding to “substrate”) surface of various watches. Alternatively, the substrate-adhering light-cutting film 10 is adhered on the surface of a UV-cutting, heat-insulating or privacy-protecting film or glass (corresponding to a “substrate”) used in various situations. ] May be removed. Alternatively, the irradiance cut film 10 for adhering the substrate is adhered to the inner surface of the glass (corresponding to the “substrate”) provided in the all-face type visor for motorcycle passengers to remove “irregular light”. You may do it.
