JPH08110756A - Plane image display body suitable for sticking to roughened surface - Google Patents

Abstract

PURPOSE: To provide a display body easily stuck to the demonstration surface of a rough stuck body and excellent in weather resistance by sticking a fiber raw material to the demonstration surface of the stuck body, and forming a laminated layer of a coated layer, an adhesive layer, an image layer, and a film layer on it. CONSTITUTION: A woven or nonwoven fabric made of synthetic fibers such as polyester is used as a substrate to be stuck to the demonstration surface of a stuck body, and a coated layer 2 is formed with an organic polymer emulsion containing inorganic powder on one surface of a substrate fiber material 1. A transparent film 5 having a display image on it printed is prepared, an image layer 4 is stuck on the coated layer 2 via an adhesive layer 3, the other surface of the fiber raw material 1 is utilized as an adhesive to the demonstration surface of the stuck body, and the image is displayed through the film (outermost layer) 5. The printed image is fixed to the outermost layer film 5, and it is not printed on the fiber raw material 1 or the coated layer 2 on it. The coated layer 2 on the fiber raw material 1 sufficiently shields sunlight via the action of the inorganic powder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat display laminate which is suitable for a relatively large-scale advertising display to be used outdoors, and more particularly, to a non-smooth surface of an adherend having unevenness or a wave surface. The present invention relates to a flat display laminate suitable for sticking to a surface or a rough surface and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, in a comparatively large-sized advertisement display used outdoors such as a vehicle side surface, a shutter surface of a store, and a partition wall,
In addition, when the surface of the adherend is uneven or has a wave surface, a film-based synthetic paper such as a substrate on which an image is printed (Tough par, Yupo, Peach coat (all are trade names)), or Tyvek, Typer, Reimei, Non-woven fabric-based synthetic paper such as Sylheim (trade name) with images printed)
To a print laminate (a method in which an adhesive is applied to a transparent polypropylene film and then dried and then adhered to the printed substrate) or a vinyl coating (a vinyl chloride / vinyl acetate copolymer resin is applied to the surface of the printed substrate and dried. , A method of pressing, etc., so that an image is displayed through the film surface of the transparent surface member, and the back surface of the substrate is attached to the display surface.

A brief description of the above described by product name is as follows. However, in the above-mentioned display laminate of the related art, probably because the sunlight is not sufficiently blocked or shielded, the exposure to sunlight for a long period of time affects the adhesion of the back surface of the substrate to the display surface, and causes various obstacles. Was causing it. For example, the generation of a partially stuck portion, the generation of peeling such as a blistering, and the like.

[0004]

SUMMARY OF THE INVENTION On the other hand, in the present invention, a woven or non-woven fabric made of synthetic fiber such as polyester is used as a substrate to be adhered to the display surface of an adherend (and no image is printed on this substrate). On one surface of the base fiber material, a coating layer was prepared from an organic polymer emulsion containing an inorganic powder, and on the other hand, a transparent film on which a display image was printed was prepared, and the image layer was adhered onto the coating layer. It was joined via an agent layer, and the other side of the fiber material surface was used as a sticking side to the adherend display surface, and the image was displayed through the film (outermost layer). As a result of the above improvement, the printed image is fixed to the outermost film (conductive layer provided on the film as described later), and is not printed on the fiber material or the covering layer thereon. The coating layer on the fiber material provides sufficient sun protection by the action of the inorganic powder. Since the pressure-sensitive adhesive layer is provided between the image layer and the coating layer, the color material of the image does not migrate to the coating layer side even when exposed for a long period of time, which brings about an effect such that the printed image is not blurred.

Next, matters related to the above summary will be described. A. Fiber material (1) As the fiber material, synthetic fibers such as polyester and nylon, or a mixed and woven fabric of synthetic fibers and other kinds of fibers,
Alternatively, non-woven fabric can be used. Among these, the non-woven fabric using the polyester fiber is preferable in terms of strength and dimensional stability against changes in temperature and humidity.

B. Coating Layer (2) Explaining the organic polymer emulsion containing the inorganic powder, titanium oxide, calcium carbonate, silica, talc, clay, etc. may be used alone or in combination as the inorganic powder. A particle size of 0.5 to 30 microns is suitable. As the organic polymer emulsion, vinyl acetate emulsion, acrylic ester emulsion (mainly composed of ethyl acrylate and -butyl ester) can be adopted, but those using acrylic resin have excellent weather resistance. It is suitable. Since this coating layer is not used later for printing, it is not necessary to impart hydrophilicity. The weight ratio of resin to inorganic powder in the emulsion composition is 1
/0.5 to 1/5, the coating can be performed by a known knife coater, roll coater, bar coater or the like. The amount (as a solid content) on the fiber surface is suitably 50 to 200 g / cm 2, and after coating and drying the emulsion, the coating layer is pressed with a calendar roll to improve the flatness,
It is preferable to crush the pinhole. The press working conditions are: temperature: 5 to 120 ° C., pressure: 10 to 10
0 kg / cm 2 is suitable. An intermediate layer may be provided by a base treatment prior to the above-mentioned inorganic powder-containing emulsion treatment in order to improve the adhesiveness between the fiber material and the inorganic powder-containing coating layer.

C. Adhesive (3) Existing adhesives or sizing agents (starch, PVA, etc.) may be used, but acrylic ester-based adhesives (based mainly on ethyl acrylate, -butyl ester) have weather resistance. Of course, when an acrylic ester emulsion is used for the coating layer, it is preferable to select the same adhesive as the adhesive.

D. Image, image layer (4) Printing of an image to be printed on the transparent film (5) can be carried out by a conventional method such as offset printing, gravure printing, screen printing, etc., but printing using computer graphic technology developed in recent years. A system that performs plateless printing without performing platemaking is particularly advantageous. The output method includes an inkjet method, a thermal transfer method, an electrophotographic method, and a Xerox type electrostatic transfer method (for example, Hands (Hands) of Fuji Xerox Co., Ltd.
Big)) etc.

E. Film (5) Conventionally used films such as polyester, vinyl chloride, polypropylene and polyethylene can be adopted. A suitable thickness is 3 to 30 μm. When performing image formation by electrostatic coating including the case where the paint or ink is a toner, it is necessary to form a conductive layer on the film surface. For this purpose, fine powder (metal oxide powder such as zinc oxide; metal powder such as copper alloy, tin, iron, aluminum, nickel, etc., conductive carbon black, etc.) that imparts conductivity to the adhesive (3). ) Is applied to the surface of the film as a primer (primer coat), and the surface resistance value is about 10 ⁵ to 10 ¹⁰ Ω / □ (□ is 1
Forming a conductive layer having a square cm). The coating conditions at this time may be substantially the same as the coating conditions for the organic polymer emulsion containing the inorganic powder described above in relation to the coating layer (2). Therefore, the film (5) is indicated by reference numeral 5aa in this case, for example, in order to cope with electrostatic painting, the above-mentioned ordinary film is dyed with a conductive dye (for example, a chromium-containing dye). The electrically conductive layer is a representative of the electrically conductive layer or the electrically conductive layer and the electrically conductive layer.
