Description

  The present invention relates to an advertisement sheet capable of displaying different advertisement contents during daytime and nighttime, and a material for producing the advertisement sheet.

  In general, an advertising medium such as a poster can be visually recognized only in the daytime when outdoors and under a bright room when indoors, and does not function as an advertising medium at night or in a dark room. Therefore, it is possible to see through the day and night by lighting up at night.

  On the other hand, advertising means using video using a transmissive screen is also conceivable, but when used outdoors in the daytime, the amount of light may be insufficient and it may be difficult to see the image, and it is costly to display the video throughout the day. Becomes bulky.

  By the way, since the age group of passers-by is different between daytime and nighttime even in the same place, in recent years, there is a demand for changing the advertisement contents between daytime and nighttime.

  In such cases, conventionally, posters have been manually changed or images have been changed.

  However, it is cumbersome to manually change the poster every day, and it may be time consuming, especially when the poster is large.

  On the other hand, when changing the image, there is no such problem, but as described above, the amount of light may be insufficient when used outdoors in the daytime, and it is costly to display the image throughout the day. It becomes bulky.

  Therefore, as a result of intensive studies to solve the above problems, the present inventor has come to solve this problem.

  That is, the advertising sheet of the present invention is an advertising sheet composed of at least a transmissive screen, and the advertising sheet is a mixture of a light-transmitting part and a concealing part in the surface direction, and It has an image part corresponding to the part which has concealment property, It is characterized by the above-mentioned.

  Preferably, the area ratio of the light-transmitting portion and the concealing portion is 1: 6 to 6: 1.

  Preferably, the haze of the transmission screen is 20 to 95%.

  In addition, the advertisement sheet production material of the present invention is characterized by comprising a see-through recording material in which a light-transmitting portion and a concealing portion are mixed, and a transmissive screen. .

  The advertising sheet of the present invention is an advertising sheet composed of at least a transmissive screen, and the advertising sheet is a mixture of a light-transmitting part and a concealing part in the surface direction, and the concealing property. Since it has an image portion corresponding to the portion having, different advertisement contents can be displayed in the daytime and at night. Moreover, such an effect can be obtained without requiring a complicated operation. Further, since the projection of the projector only needs to be performed at night, the cost does not increase when used.

  The advertising sheet of the present invention is an advertising sheet composed of at least a transmissive screen, and the advertising sheet is a mixture of a light-transmitting part and a concealing part in the surface direction, and the concealing property. It has an image portion corresponding to the portion having. Hereinafter, embodiments of each component will be described.

  FIGS. 1-1 to 1-3 are side views showing an embodiment of the advertisement sheet of the present invention. Such an advertisement sheet 1 is used together with the projector 14 as shown in FIGS. 2-1 and 2-2. When the advertisement sheet used in this way is observed from the side opposite to the projector, the image portion corresponding to the concealing portion is observed during the day, and the image portion is not observed at night. On the other hand, by projecting with a projector, an image projected on a transmissive screen is observed through a portion having optical transparency. Therefore, different advertisement contents can be displayed in the daytime and at night.

  The advertisement sheet is a mixture of a light-transmitting part and a concealing part in the surface direction, and an image part corresponding to the concealing part. The mixed pattern of the light-transmitting part and the concealing part is not particularly limited. For example, a halftone dot shape as shown in FIG. 3-1, a strip shape as shown in FIG. Stuff.

  The portion having light permeability in the surface direction of the advertisement sheet has a role of making it possible to visually recognize an image projected on the transmission screen at night through the portion. In addition, when the haze (JIS K7105: 1981) of the light-transmitting part is 60% or less, when the projector is not projected, the viewer side can be seen from the projector side or the viewer side can be seen through the part. It is also possible to see the projector side.

  The degree of light transmission of the light-transmitting part is not particularly limited as long as the image displayed on the transmission screen is visible, but usually the total light transmittance (JIS K7361-1: 1997) And 60% or more, preferably 80% or more, more preferably 90% or more.

  The portion having the concealing property in the surface direction of the advertisement sheet has an image portion corresponding to the portion. As an example in which the image portion corresponds to the concealing portion, for example, the concealing portion 4 and the image portion 5 are made to correspond to the transmissive screen 2, and the concealing portion 4 is made to correspond to the image portion 5. As shown in FIG. 1-1, a part 4 having concealment is provided on one surface of the transmission screen 2, and the surface opposite to the surface is made to correspond to the part having concealment. The image portion 5 is provided (FIG. 1-2), and the image portion 51 having concealment is provided on the transmission screen 2 (FIG. 1-3).

  Such an image portion corresponds to an image observed in the daytime. Since this image portion has a concealing property, the image of the image portion can be easily seen in the daytime. In addition, since the image part has concealability, the light of the image part of the light projected from the projector onto the transmissive screen can be blocked and the image part can be prevented from being illuminated. The image becomes difficult to see. Therefore, even when the projector is used at night, two different advertisement contents are not observed at the same time, and the image projected on the transmission screen observed through the light-transmitting portion does not become difficult to see.

  In the advertisement sheet, it is sufficient that the image of the image portion can be observed from at least one surface. When the image can be observed only from one side, the advertising sheet is used so that the surface on which the image can be observed faces the surface opposite to the surface on which the projector is installed (FIGS. 2-1, 2). 2-2). In the advertisement sheet, the image may be observable from both sides, and in that case, different images may be observed on the front and back sides.

  In the surface direction of the advertisement sheet, the area ratio of the light-transmitting part and the concealing part is 1: 6 to 6: 1, preferably 1: 4 to 4: 1, more preferably 1: 4 to 1: 1 is desirable. By setting the area ratio of both to 1: 6 to 6: 1, it is possible to improve the balance between images that can be observed in the daytime and images that can be observed in the nighttime. Moreover, it is preferable to mix many and fine parts which have a light transmittance and a part which has concealment property. For example, when mixed in a halftone dot shape, the diameter of the halftone dot is 5 mm or less and the interval between the halftone dots is 5 mm or less. When mixed in a lattice shape, one side of the lattice is mixed in a strip shape of 4 mm or less. The width of the strips is preferably 4 mm or less and the interval between the strips is preferably 4 mm or less.

  As such an advertisement sheet, for example, an image obtained by partially printing an image with a concealing ink on a transmissive screen (FIG. 1-3), or printed on one surface of the transmissive screen. A pattern having a concealing property is partially provided by, for example, and an image is provided by printing or the like on the surface opposite to the surface corresponding to the concealing portion (FIG. 1-2), or A transparent display object 7 in which a non-image portion having light transparency and an image portion having concealment are mixed, and a transmission screen 2 are arranged so that the surfaces face each other (see FIG. 1-1). Among these, since it is difficult to perform printing directly on a transmissive screen, a transparent display object (hereinafter, referred to as a non-image portion having a light transmission property and an image portion having a concealment property). In some cases, the display screen may be simply referred to as a “transparent display object”) and a transmissive screen so that the surfaces face each other.

  There is no particular limitation on the means for arranging the display object that can be seen through and the transmissive screen so that the surfaces face each other, but the two can be bonded using an adhesive, or both can be fixed using a frame. A means to do is given. Further, it is preferable that the transparent display object and the transmission type screen are arranged in close contact with each other, but there may be a slight distance. Here, the transmissive screen is usually arranged on a surface opposite to the surface on which the image of the transparent display object is observed, as shown in FIGS. When the rate is 90% or more, the image may be arranged on a surface on which an image of a display object that can be seen through is observed.

  As a see-through display object, an image is printed on a recording material that is light-transmissive on the entire surface and an image is partially printed with a concealing ink, or on a recording material that is entirely concealed. , A part in which a large number of through-holes are formed after printing, or a part having the concealability of the recording material using a see-through recording material in which a part having optical transparency and a part having concealment are mixed In other words, an image is printed corresponding to the above, or a display object such as a poster on which the entire surface on which an image has already been formed has a large number of through holes formed. Among these, the former three are preferable in that a desired image can be formed. Further, the ink at the time of printing is not limited to the one having a concealing property, and a punching machine for forming a through hole is unnecessary. Therefore, it is preferable to use a fluoroscopic recording material in which a light-transmitting part and a concealing part are mixed, and an image printed on the recording material corresponding to the concealing part. used. Therefore, as a material for producing the advertisement sheet, a material composed of a transparent recording material in which a light-transmitting part and a concealing part are mixed and a transmissive screen is preferable.

  As a recording material having light transmittance on the entire surface, a recording material having a light-transmitting ink-receiving layer on a light-transmitting substrate, and as a recording material having a concealing property on the entire surface, concealment For example, a layer having an ink-receptive property provided on a substrate having a property.

  Examples of the light-transmitting substrate include polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycarbonate, polyethylene, polypropylene, polystyrene, triacetyl cellulose, and a plastic film made of acrylic. As a support having a concealing property, a white pigment or a black pigment is kneaded into the base material, and a concealing layer is formed on the base material by applying a black paint or vapor-depositing a metal thin film. In addition, synthetic paper, paper, fiber fabric, and the like can be used.

  The layer having ink receptivity is mainly formed from a resin having ink receptivity. As the resin having ink receptivity, a known resin can be used according to the recording device to be used (ink jet printer, laser beam printer, thermal transfer printer, etc.). For example, when using an inkjet printer, natural resins such as albumin, gelatin, casein, starch, arabic gum, sodium alginate, carboxymethylcellulose, hydroxyethylcellulose, polyamide, polyphenylacetoacetal, polyvinylacetal, polyethyleneimine, polyvinylpyrrolidone, melamine resin , Synthetic resins such as polyurethane, polyvinyl alcohol, polyester, poly (meth) acrylic acid soda, and (meth) acrylic acid ester copolymers can be used.

  As a see-through recording material in which a light-transmitting part and a concealing part are mixed, for example, a concealing and ink-receptive layer is formed on a base material having a light-transmitting surface as a whole. For example, a part provided or a part having a large number of through holes and a part other than the through holes having a concealing property and an ink receiving property can be used. Among these, the former has a large number of through-holes, and the portions other than the through-holes are concealed because the position adjustment for accurately printing on the concealment pattern must be performed at the time of printing. A transparent recording material that is both ink-receptive and ink-receiving is preferably used. The area ratio of the light-transmitting part and the concealing part of the see-through recording material in which the light-transmitting part and the concealing part are mixed is 1: 6 to 6: 1. The ratio is preferably 1: 4 to 4: 1, more preferably 1: 4 to 1: 1.

  The see-through recording material 8 having a large number of through-holes, and the portions other than the through-holes are concealing and ink-receptive, is, for example, a layer 10 having ink-receptivity on one surface of a substrate 9, It can be obtained by providing a large number of through-holes 12 with a punch press or the like in a recording material having a structure having an adhesive layer 6 and a separator 11 on the surface (FIG. 4). The concealing property may be imparted by any one of the base material, the ink receptive layer, the adhesive layer, or a combination of these layers. The concealability can be imparted by adding a black pigment or a white pigment to each layer.

  When printing is performed on a transparent recording material 8 having a large number of through-holes and the portions other than the through-holes are concealing and ink-receptive, a conveyance failure can be prevented or a printer can be used. In order to prevent internal stains, it is preferable to stack the conveyance auxiliary member 13 on the surface opposite to the recording surface (surface having ink receptivity) (FIG. 4).

  The conveyance replenishing member is not particularly limited as long as it does not have a hole, and paper, plastic film, fiber cloth, or the like can be used. Further, it is preferable to select a member having ink absorptivity in accordance with the ink of the recording apparatus to be used. For example, when the recording device is an ink jet printer, the transport auxiliary member is an ink jet recording film in which a layer having ink absorbability is formed on a substrate such as paper, fiber fabric, or plastic film having ink absorbability. Are preferably used.

  The area ratio between the non-image portion having light transparency and the image portion having concealment in the transparent display object is 1: 6 to 6: 1, preferably 1: 4 to 4: 1, more preferably 1: It is desirable to be 4 to 1: 1.

  Moreover, it is preferable that the display object which can be seen through has an adhesive layer on the surface side to be overlapped with the transmission screen. Adhesives that make up the adhesive layer include various adhesives, such as adhesives that are adhesive at room temperature, and hot-melt adhesives that are non-adhesive at room temperature but exhibit adhesive properties when heated during application. Agent. These adhesives include natural rubber-based, recycled rubber-based, chloroprene rubber-based, nitrile rubber-based, styrene / butadiene-based elastomer adhesives, epoxy-based, urethane-based, acrylic-based, cyanoacrylate-based synthetic resin adhesives, etc. In addition, ultraviolet curable adhesives, electron beam curable adhesives, emulsion adhesives, and the like can be given. In addition, when providing an adhesive layer, it is preferable to laminate | stack separators, such as paper and a plastic film, on an adhesive layer.

  The adhesive layer preferably has an adhesive formed in a matrix. By forming the adhesive in a matrix, air that has entered between the adhesive layer and the transmissive screen can be released when pasting to the transmissive screen, improving the efficiency of the pasting operation and improving the appearance. It is possible to prevent damage.

  The transmissive screen is not particularly limited as long as it can project the projection light from the projector, and only a layer having light diffusibility (hereinafter, sometimes simply referred to as “light diffusing layer”). Or those having a light diffusion layer on a substrate can be used.

  The light diffusion layer is obtained by dispersing fine particles inside the transparent binder, and scatters the light projected from the projector to the viewer side. Here, the transparent binder containing fine particles is not limited to a solid and may be a fluid such as a liquid or a liquid crystal as long as it has optical transparency and can hold fine particles. However, in order to maintain the shape of the screen with only the light diffusion layer, glass or polymer resin is preferable.

  Here, examples of the glass include oxide glass such as silicate glass, phosphate glass, and borate glass. Examples of the polymer resin include polyester resin, acrylic resin, polyester acrylate resin, and polyurethane. Acrylate resins, urethane resins, epoxy resins, polycarbonate resins, acetal resins, vinyl resins, polyethylene resins, polystyrene resins, polypropylene resins, polyamide resins, polyimide resins, melamine resins, phenolic resins Thermoplastic resins such as resins, silicone resins, and fluorine resins, thermosetting resins, ionizing radiation curable resins, and the like can be used.

  As fine particles to be included in the transparent binder, inorganic fine particles such as silica, alumina, talc, zirconia, zinc oxide and titanium dioxide, and organic fine particles such as polymethyl methacrylate, polystyrene, polyurethane, benzoguanamine and silicone resin are used. can do.

  The base material is not particularly limited as long as it has good light transmittance, such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycarbonate, polyethylene, polypropylene, polystyrene, triacetyl cellulose, acrylic, polyvinyl chloride, etc. A plastic film or the like can be used.

  The optical performance of the transmission screen is not particularly limited, but haze (JIS K7136: 2000) is 20 to 95%, preferably 30 to 60%. An image can be displayed by setting the haze to 20 to 95%. Furthermore, by setting the haze to 30% or more, a video can be clearly displayed, and by setting the haze to 60% or less, it is possible to see the opposite side through the light-transmitting portion of the advertisement sheet. The haze of the transmission screen can be appropriately adjusted depending on the thickness of the light diffusion layer, the content of fine particles, and the like. For example, when the thickness of the light diffusion layer is 20 μm, the haze can be reduced to 20 to 95% by setting the content of fine particles to 50 to 200 parts by weight with respect to 100 parts by weight of the transparent binder.

  The total light transmittance (JIS K7361-1: 1997) of the transmissive screen is 60% or more, preferably 80% or more, and more preferably 90% or more.

  In addition, the transmission screen may have an adhesive layer for attaching to a display object that can be seen through, other separators, and the like.
