Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a poster for a common guide item that can be repeatedly used even if the time or place changes by writing and erasing in the fields such as time and place in the guide item.

[0002]

[Prior art]

 In general, information posters are used by printing or copying the same content on paper or synthetic paper to create multiple sheets and displaying them at required places. By the way, in many cases, the guidance posters used when the same event or event is held multiple times can be used in common by rewriting only the date and time and place of the event. In such cases, usually, to save poster production costs, leave the date and place blank, and print out only the other common information items to create the required number of copies. I write down the date, time, and place each time it is held.

However, such a guide poster cannot be reused after it is used up once the date and place have been written, and it must be changed to a new one each time it is used. In addition, there is a drawback that it is not possible to spend much cost, and it is not so desirable from the viewpoint of resource saving.

[0004]

[Problems to be solved by the device]

 The present invention overcomes the drawbacks of the conventional guide posters described above, and can write the variable item display part such as the date and time and place at any time, and wipes and erases it when used. The challenge is to provide posters that can be used repeatedly.

[0005]

[Means for Solving the Problems]

 As a result of various researches on guide posters, the present inventors have left the variable item display part blank on one surface of a transparent or non-transparent substrate sheet, and described the guide item including only the invariant item display part. It was found that the above-mentioned problems can be solved by forming a pattern and making the other surface a surface on which writing with a water-based ink and its wiping and erasing are possible, and the present invention has been made based on this finding.

That is, the present invention provides a guide poster carrying an image pattern on which a guide matter consisting of an invariant matter display portion and a variable matter display portion is carried on a base sheet, wherein the base sheet is placed on one surface. A transparent or semi-transparent substrate film, in which a marking layer capable of writing with a water-based ink and its wiping and erasing are laminated via an undercoat layer, and an ink receiving layer is laminated on the other surface via an undercoat layer. It has a structure in which the ink-receptive layer carries a reverse image pattern from an original formed by an inkjet method, or the above-mentioned base sheet has a transparent surface on which one surface is writable and erasable by writing with an aqueous ink. To a semi-transparent substrate film, an ink receiving layer is laminated on the other surface of the film via an undercoat layer, and The present invention provides a guide poster on which the variable item display portion can be written and the information can be wiped and erased, which has a structure in which a reverse image pattern from a document formed by an inkjet method is carried on the recording layer. is there.

[0007]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an enlarged cross-sectional view of an example of a poster for guiding the present invention, in which a marking layer 2 is provided on one surface of a base film 1 with an undercoat layer 3 interposed, and an undercoat layer is provided on the other surface. An ink receiving layer 4 is provided via 3 '. The ink receiving layer 4 carries a reversal image pattern 5 in which guide matters formed by the ink jet method are described. The substrate film 1 is not particularly limited as long as it is a transparent or translucent material so that the image pattern formed on one surface can be observed from the other surface. Examples of such a material include paper, a glass plate, and a plastic film. Among them, a plastic film is preferable, and any material can be selected from polyethylene terephthalate, polyethylene, polypropylene, polyamide and the like. Of these, polyethylene terephthalate is particularly preferable in terms of dimensional stability and flatness. The thickness of this film is usually in the range of 25 to 250 μm, preferably 50 to 150 μm.

The marking layer 2 provided on one surface of the base film 1 with the undercoat layer 3 interposed therebetween allows easy writing with a water-based ink, and the writing can be easily erased by wiping. It must be made of a material that can. Such materials include synthetic resins such as polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyolefin resins such as polyethylene, polypropylene and ethylene-propylene copolymer, polyamide resins, acrylic resins. And so on. The marking layer formed of these synthetic resins preferably has a wetting index measured according to JIS K6768 in the range of 15 to 40 dyn / cm. When the wetting index is less than 15 dyn / cm, writing with an aqueous ink becomes unclear, and when it is more than 40 dyn / cm, wiping is difficult when erasing a written content.

It is advantageous that the marking layer 2 has a standard wiping / erasing rate of 50% or more, preferably 80% or more with respect to the water-based ink used for writing. When the standard wiping / erasing rate is less than 50%, when the written information is erased, the water-based ink remains and the original state cannot be restored. This standard wipe erasure rate is the magic chalk No. Fill 4 cm ² of the marking surface of the sample with 620 medium characters, and after drying for 30 minutes, fix the absorbent cotton on the peding / slipping / scratch tester [made by HEIDON; product name H EIDON 14]. Calculated according to the following formula, measuring the light transmittance a ₀ of the sample before applying the water-based ink and the light transmittance a after wiping by moving back and forth 10 times at a load of 200 g and 3000 mm / min. Is.

[0010]

(Equation 1)

As the light transmittance after wiping, an average value of values measured at a central point of the sample and two points 5 mm apart from each other in the wiping direction in the wiping direction is used.

Instead of providing the marking layer 2, the surface of the substrate film may be processed and formed by adjusting the wetting index in the range of 15 to 40 dyn / cm or the wiping erasure rate of 50% or more. Means for processing the surface of the substrate film to adjust the desired physical properties include adjusting the surface smoothness by rolling, corona discharge, and adjusting the surface condition by plasma treatment.

The marking layer 2 is, for example, an emulsion containing an acrylic resin cross-linked with an amino-based or phenol-based curable resin in advance, and has an average particle diameter of 0.01 to 1.0 μm, preferably 0.05 to A coating solution prepared by adding 0.5 μm organic resin particles, for example, polyethylene resin particles, is applied to a base film according to a conventional method and dried, or an acrylic resin which is not crosslinked is required together with polyethylene resin particles. It can be formed by adding an amount of a cross-linking agent to prepare an emulsion coating solution having a solid content of about 10 to 40% by weight, applying this on a base film, and then cross-linking the acrylic resin. it can. At this time, if desired, a surfactant and various conventionally used additives such as a lubricant, a stabilizer, and a coloring agent can be added to the coating liquid. The thickness of the marking layer 2 is usually 0.5 to 10 μm, preferably 1 to 5 μm.

Next, as the undercoat layers 3 and 3 ′ to be interposed between the marking layer 2 and the base film 1 and between the base film 1 and the ink receiving layer 4, usually, saturated polyester resin or urethane is used. Although a resin or the like is used, a urethane resin is particularly preferable as the undercoat layer 3'because it has good adhesion to the ink receiving layer. The coating amount of the undercoat layer is usually in the range of ^{3 to} 15 g / m ^{2 on} one side.

As the ink receiving layer 4 provided via the undercoat layer 3 ′, among the layers conventionally used as the ink receiving layer of the recording material for ink jet, the ink receiving layer on the side opposite to the ink receiving layer is provided. A pattern from which a pattern can be observed can be arbitrarily selected and used, but it is preferably composed of at least one layer containing a water-soluble, water-absorbing polymer compound or a water-resistant water-soluble polymer compound as a main component.

Examples of such a material include 100 parts by weight of polyvinylpyrrolidone and at least one of polyvinyl alcohol and polyvinyl acetal mixed in a weight ratio of 1: 9 to 6: 4, and an alkali of polystyrene sulfonic acid. Alternatively, there may be mentioned a composition containing 10 to 35 parts by weight of a quaternary ammonium salt or a layer composed of a composition in which polyvinyl alcohol or polyvinyl acetal therein is crosslinked.

The ink receiving layer 4 carries an image pattern 5 on which guide items other than the variable item display portion are written. The image pattern 5 is formed as an inverted image of the original by an inkjet method. It is a thing. This can be easily formed by using an ink jet printer using a computer which has been generally used so far. FIG. 2 is a systematic diagram of an example thereof. The input means in the figure indicate a device such as a keyboard, a mouse, and a scanner for taking in a prepared original drawing pattern so that it can be used by a computer and storing it. The means is, for example, a hard disk, a floppy disk, a magneto-optical disk, or the like, which stores data, and takes it out when necessary or newly stores data. The central processing unit is used to create and process the required pattern data of the original drawing, store the data in the storage device, display the data, and output the data. The display means is for displaying data, and the output means is for printing out the data created and processed by the central processing unit, such as an ink jet printer, plotter, sublimation printer, electrophotographic printer. Examples include printers.

3 and 4 are process diagrams of different types of forming patterns in the ink receiving layer using hardware. According to the process of FIG. 3, the ink receiving layer is formed as a first step. The pattern to be formed on the substrate is created using the central processing unit and the input device (image creation stage), the pattern data sent from the central processing unit is recorded in the storage means, and the pattern data sent from the central processing unit is recorded. The output means receives (image information receiving step), the received data is processed on the output means side (in this case, the pattern is reversed image, image information processing step), and the output means, particularly the inkjet, one side. Is a marking surface that is writable and writable and erasable by a water-based ink, and the other surface serves as an ink-receiving layer to form an image pattern on the ink-receiving layer of the substrate (image. By forming the image information on the ink receiving layer), a required guiding poster can be obtained.

On the other hand, according to the process of FIG. 4, a previously created pattern is used as an image pattern to be formed on the ink receiving layer, and this pattern is changed from the storage means or the input means to the central processing unit. Then, the pattern data is processed and corrected using the central processing unit and the input means to complete the pattern. In FIG. 3, the original image is inverted by the output means. In this case, the central processing unit creates an inverted image of the original image, sends the data to the output means, and forms a pattern on the ink receiving layer. You can get the information poster.

The image pattern formed on the ink receiving layer can be repeatedly created by storing pattern data in the storage means.

The poster of the present invention is used to inform posters of events such as concerts, lectures, entertainers, exhibitions, art exhibitions, mobile classrooms, summer courses, and travel events. You can list posters, posters that show menus at restaurants and coffee shops, posters that show construction plans at construction sites, posters that show the date and time of ceremonial occasions, places, posters for advertisement on special sale days in shops, etc. .

In these posters, the invariant item display portion for transmitting common information is carried as an image pattern on the ink receiving layer, and the date, place, construction period, organizer, menu contents, etc. The variable item display part, which is changed depending on the conditions of use, is written with water-based ink each time and used in a completed state.

Then, after the event or event is over and the role as a guide poster is fulfilled, the part written with the water-based ink is wiped and erased so that it can be repeatedly used for the next event.

The size of the guide poster of the present invention can be appropriately selected from a large size such as B0 version to a small size such as A5 size according to the purpose of use.

In the guide poster of the present invention, various characters, numbers, symbols and the like can be additionally written with a water-based ink on the variable item display portion, and after use, it can be wiped and erased. It can be restored to its original state. As the water-based ink, for example, ink pens for various boards sold for white boards (markers for white boards made by KOKUYO, magic chalk white boards, etc.) are used. By adding necessary items such as handwriting on the marking surface with this water-based ink and wiping it off with a fibrous material after use, the guide poster is regenerated.
