Abstract

PROBLEM TO BE SOLVED: To hold various sizes of photographs detachably readily, and hold photographs without being impaired when they are to be stuck again, by providing a transparent film to be opposed to the static attraction surface of a base material, and sticking the base material and the transparent film at least at a part thereof. SOLUTION: The statically attractive base material 2 has a statically attractive force by frictional electrification on at least one surface, thereby holding photographs. For this, frictional electrification is generated by turning over sometimes the transparent film 1 joined to the base material. Such a static electrification chargeable polymer is not limited in particular; however, there are given acrylic resin, vinyl chloride resin, vinyl acetate resin, or the like. The base material is generally to be 0.1-5 mm, and is desirable to be 0.5-3 mm suitably. In order to prevent the transparent film 1 from being shifted of the position capable of covering the holding surface of the base material, it needs to be joined in the base material and at least a part of the joined part 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an album,
The present invention relates to a sheet for pasting photos constituting an album, and more particularly to an album sheet that can be re-pasted without damaging the photos.

[0002]

2. Description of the Related Art Heretofore, there has conventionally been made a film such as a pocket for storing a photograph in advance to form a photo album.

[0003] However, such a camera can only store photos of a predetermined size, and cannot determine the layout by itself.

[0004] There is also a photo album in which a photograph or the like is held with weak adhesion, and a transparent film is placed thereon.

Such a device can hold a photograph of any size within the range of the adhesive surface,
You can also arrange photos in your favorite layout.

[0006]

However, although such a material is weakly adherent, since the photograph is held with an adhesive, it is difficult to peel it off when reattaching the photograph, and it is difficult to peel the photograph forcibly. Then, it was sometimes damaged.

Further, there is another problem that a photograph cannot be held if dust or the like adheres to the adhesive surface.

Therefore, the present invention is capable of easily holding photos of various sizes, allowing a layout of your own choice, and preventing damage to the photos when re-attaching the photos. It is an object of the present invention to provide an album sheet which can protect the image from scratches and dust.

[0009]

The album sheet according to the present invention is an album sheet comprising a transparent film and a substrate capable of being electrostatically attracted on at least one side, wherein the transparent film is electrostatically attracted to the substrate. The transparent film is provided so as to face the surface, and the base material and the transparent film are joined at least in part.

Furthermore, a writing layer is provided on at least a part of the transparent film opposite to the substrate.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the album sheet of the present invention will be described below.

The transparent film has such a transparency that the photograph to be held can be seen, and protects the held photograph and the holding surface of the base material from adhesion of scratches and dust. Further, since the photograph is sandwiched between the base material and the transparent film, the holding force of the base material designed to have a weak holding force for attaching and detaching the photograph can be compensated. This is because the base material can hold the photograph itself and the base material can hold the transparent film in a part other than in contact with the photograph as the force for sandwiching the photograph, and the two kinds of forces hold the photograph. That's why.

Therefore, the transparent film may be one as long as it can cover the holding surface of the substrate, or two or more sheets may be arranged side by side.

Further, it is desirable that the transparent film is not large enough to completely cover the substrate, but is slightly smaller than the substrate. Because it is conceivable to bind one side of the album sheet when creating an album, and in such a case when binding the joint between the transparent film and the base material, the transparent film may be turned up even after binding. Although there is no problem, it is to eliminate the inconvenience that the transparent film cannot be turned up after the binding to the transparent film when binding at a portion other than the joint.

As the transparent film, resin sheets such as polyester, polyethylene, polycarbonate, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile, ABS, nylon, polypropylene and polystyrene can be used. 4-2
About 00 μm is appropriate.

A writing layer can be provided on the surface of the transparent film opposite to the substrate. Such a writing layer may be provided on a part of the transparent film or on the whole of the transparent film. By providing such a writing layer,
Characters can be written on the surface of the transparent film. By doing so, writing can be performed while visually recognizing the photo sandwiched between the transparent film and the base material, and the photo is not stained.

As such a writing layer, there are a conventionally known whiteboard writing layer which can be written with an aqueous or oily pen and erased by wiping, and a trace layer which can be written with a pencil or a pen.

Further, on the back surface of the writing layer of the transparent film, a process for preventing transfer can be carried out so that transfer of photographic emulsion and characters of a sandwiched memo does not occur.

Next, the substrate capable of electrostatic attraction is for holding a photograph by adsorbing a photograph and a transparent film.

The substrate capable of electrostatic attraction has at least one surface having an electrostatic attraction force due to triboelectric charging and capable of holding a photograph. Therefore, it is necessary to cause triboelectric charging in order to hold the substrate. As a method of causing triboelectric charging, it is possible to cause triboelectric charging by rubbing photographs in advance, but without doing so, it is necessary to turn the transparent film bonded to the substrate several times Raising can cause triboelectric charging.

Examples of such a substrate that can be electrostatically adsorbed include a polyvinyl chloride film containing an organic ketone having 40 to 60 carbon atoms, a polyvinyl chloride film containing an organic tin-based stabilizer, and a polypropylene film. Yes, and
There is a sheet-like or plate-like thing in which an electrostatic attraction layer is formed.

As the electrostatic attraction layer, there is a porous or porous layer made of an electrostatically chargeable polymer. In order to form such a layer, an electrostatically chargeable polymer is formed by a good polymer. There is a method of dissolving in a solvent in which a solvent and a poor solvent are combined, and coating and drying the solution on a support. In this case, the diameter of the pores can be changed by changing the ratio of the good solvent to the poor solvent, and a porous or porous layer can be formed.

The polymer capable of electrostatic charge is not particularly limited, but specific examples thereof include acrylic resin, vinyl chloride / vinyl acetate resin, vinyl chloride / vinyl acetate / maleic acid resin, styrene / acrylic resin, and acryl / vinyl chloride. Resin, unsaturated polyester, chlorinated rubber, vinyl acetate resin, cellulose acetate resin, ethyl cellulose resin, phenol resin, acrylonitrile / vinylidene chloride resin and the like.

Although the thickness of the substrate depends on the substrate, it is generally 0.1 to 5 mm, preferably 0.5 to 3 mm.

Further, a paperboard, a resin sheet, or the like can be attached to the back surface of the surface of the substrate that can be electrostatically attracted in order to give the substrate a thickness.

In order to enable both sides of the substrate to be electrostatically adsorbed, a method of coating and forming an electrostatic adsorption layer on both sides of a sheet-like material or bonding the electrostatic adsorption layer to both sides of a paperboard or a resin sheet are used. And a method of bonding the back surfaces of two substrates that can be electrostatically attracted to each other.

Each of the above-mentioned layers can be provided with a function of blocking ultraviolet rays in order to prevent deterioration due to ultraviolet rays, and can be provided with antibacterial properties in order to prevent the growth of various bacteria.

When each of the above-mentioned layers is formed by coating, a coating solution obtained by dissolving or dispersing each of the above-mentioned resins in an appropriate solvent is applied to, for example, a bar coater, gravure coater, curtain coater, roll coater, blade coater or the like. It can be formed by coating and drying with an appropriate coating device.

Next, in order to prevent the transparent film from being displaced when the transparent film is turned up or the like and from being displaced from a position at which the holding surface of the substrate can be covered, at least the transparent film is displaced from the transparent film. It is necessary to be partially joined.

Examples of a method of partially joining the base material and the transparent film include joining one side end of the transparent film to the base material and joining two sides of the transparent film to the base material. Alternatively, a method of bonding several points on one side of the transparent film to the base material in a dot-like manner may be employed. Furthermore, the part to be joined may be at the upper end, right end, left end, etc. of the base material, and may be joined on the back surface of the base material,
You may comprise so that a transparent film may be folded back on a base material surface.

In addition, a transparent film is applied on one side of
Examples of the case where two or more transparent films are arranged side by side include a method of arranging two transparent films horizontally, arranging two vertically, or arranging four sheets of two vertically and two horizontally.
When both surfaces of the substrate can be electrostatically attracted, the front and back surfaces of the substrate can be covered with one transparent film. An example of such a case is one in which the center of the transparent film is joined to the edge of the base material (FIG. 2).

As means for joining the transparent film with the holding surface of the base material, there are a method of bonding with a pressure-sensitive adhesive, an adhesive, a double-sided tape or the like, and a method of bonding the transparent film with heat fusion, ultrasonic fusion, solvent or the like. Or by dissolving a part of the base material.

Then, an album can be produced by spelling out several album sheets.

On the other hand, the following coating solution for an electrostatic adsorption layer was applied to one side of a 100 μm polyester film using a Meyer bar, and dried at 60 ° C. for 5 minutes to form an open hole having a thickness of 6 μm and an average of 2 μm. An electrostatic adsorption layer of a porous film was formed, and two substrates each having a size of A4 and capable of electrostatic adsorption on one side were produced. The back surface of the electrostatic attraction layer of the obtained base material was adhered to a cardboard having a thickness of 1 mm with an adhesive to prepare a base material capable of electrostatic attraction on both sides.

<Coating liquid for electrostatic adsorption layer> Acrylic resin (Acryhase MM428: Fujikura Kasei Co., Ltd.) 5 parts Ethanol 50 parts 1,1,1-trichloroethylene 45 parts

Next, using a double-sided adhesive tape having a width of about 0.5 cm on the short side of the back side of the whiteboard writing layer of the transparent film, the surface of the electrostatically adsorbing layer provided on both sides of the substrate which can be electrostatically adsorbed, respectively. The sheets were joined to obtain an album sheet.

Similarly, ten album sheets were prepared.

Further, an album was produced by making a hole in a portion of the base material that was not covered with the transparent film on the side facing the side where the transparent film and the base material were joined, and binding with a string.

In the album obtained as described above, various photo sizes could be arranged in a layout of your choice.

Also, when re-attaching the photograph, the photograph could be easily removed from the substrate, and the photograph could be re-attached without being damaged.

Furthermore, when writing was performed with a white board marker (Board Fax Marker: Plus Kogyo Co., Ltd.), clear writing was possible without repelling the image, and erasing was easy.

Also, while looking at the picture, you can write on it,
Also, since the film was covered with a transparent film, the photograph was not stained or scratched.

[0046]

The album sheet of the present invention can easily hold photos of various sizes, can be laid out as desired, and does not damage the photos when re-attaching the photos.

Further, since the film is covered with the transparent film, the film can be protected from scratches and the adhesion of dust and the like can be prevented.

The deterioration of the photograph can be prevented by giving the transparent film an ultraviolet blocking function.

Further, since the transparent film is charged when it is turned up, it is not necessary to rub the photograph when charging the transparent film to attach it to a substrate capable of electrostatic attraction.

Since the substrate has an appropriate holding force, the photograph does not stick to the transparent film or fall when the transparent film is turned up.

Further, when the transparent film has a writing layer, writing can be performed while visually recognizing the photograph, and writing can be performed through the transparent film, so that the photograph is not stained or scratched.
