Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin sheet whose surface is subjected to special treatment and display can be removed.
[0002]
[Prior art]
Conventionally, synthetic resin sheets that have undergone special treatment (such as UV curable resin coating treatment, fluorine resin coating treatment, fluorine film laminating treatment, etc.) have been known and sold in roll form. There are many cases.
[0003]
This synthetic resin sheet has a description sticker attached to the end of the paper tube of the roll in order to inform the customer what kind of processing is being performed and its function.
[0004]
However, since only the small sticker can be attached to the end of the paper tube, there is a problem that it is difficult for the consumer to recognize the contents described on the sticker.
[0005]
Further, in order to inform the consumer what kind of processing is performed on the synthetic resin sheet and its function, a method of displaying the contents on the display frame of the roll is conceivable.
[0006]
However, since various types of rolls of synthetic resin sheets are usually arranged in one display frame, there is a problem that it is difficult to understand which synthetic resin sheet the described content relates to.
[0007]
In addition, roll sheets are usually cut by measuring the quantity required at the time of sale, but there is a problem of reduced workability that must be measured every time it is cut, and inventory management is performed. In some cases, it has been desired that the roll sheet itself be given a quantity because it is necessary to grasp the remaining amount of the roll sheet.
[0008]
[Problems to be solved by the invention]
In view of this, the present invention is intended to provide a synthetic resin sheet in which the details of the processing performed, the description of its function, the quantity and remaining amount of sheets, etc. can be grasped more easily than before.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the present invention takes the following technical means.
(1) The synthetic resin sheet from which the indication of the present invention can be removed has been subjected to a special treatment, and explanation of the content of the special treatment or / and explanation of its function by a paint containing a pigment and a water-soluble resin or / And a scale for grasping the length when cutting the sheet or / and the remaining sheet length for inventory management are displayed, and the display can be wiped off by wiping with water And
[0010]
Since this synthetic resin sheet displays the description, quantity, etc. of the contents of the special processing, it is possible to grasp the explanation, quantity, etc. (for example, a scale indicating the remaining sheet amount) from the sheet itself.
[0011]
Here, the description, quantity, etc. of the contents of the special processing can be displayed on the front surface, back surface, side surface (when the thickness of the sheet is thick), or the like.
[0012]
Further, the display is made of a paint containing a pigment and a water-soluble resin, and can be wiped off by wiping with water, so that it can be erased by wiping with water.
[0013]
Examples of the material of the synthetic resin sheet from which this display can be removed include polyvinyl chloride resin, polypropylene resin, polyethylene resin, polyester resin, and acrylic resin. In addition, when attaching the display of description, such as the content of special processing, to the back surface side of a sheet | seat, it is preferable that a synthetic resin sheet shall have transparency from a viewpoint of visibility.
[0014]
The contents of the special treatment include antibacterial treatment, antifungal treatment, dustproof treatment, antifouling treatment, deodorization treatment, deodorization treatment, water repellent treatment, antistatic treatment, electrostatic removal treatment, scratch resistance treatment, antifriction treatment, insecticide Examples thereof include processing, anti-fogging processing, anti-slip processing, glazing processing, and far-infrared processing. This processing may be one type of processing or two or more types of processing, and may be single layer processing or multi-layer processing.
[0015]
Examples of the water-soluble resin of the paint include polyvinyl alcohol resin, acrylic resin, and cellulose resin.
[0016]
As a display of the description of the content of the special processing, the presence of the special processing surface, the effects and functions of the special processing, the usage precautions, etc. are illustrated in an easy-to-understand manner to the consumers etc. with letters and illustrations etc. Can do.
[0017]
In addition, as the description of the quantity, “scale” for grasping the length when the synthetic resin sheet is cut at the time of purchase (for example, cm unit or m unit) or the remaining for inventory management. For example, adding a quantity can be exemplified.
[0018]
Examples of means for providing the special processing layer and description display include printing techniques such as gravure printing, offset printing, silk screen printing, and flexographic printing.
(2) As described above, using a paint containing a pigment and a water-soluble resin, display can be performed by a printing technique such as gravure printing, offset printing, silk screen printing, or flexographic printing.
[0019]
And, for example, by adjusting the viscosity of the paint to an appropriate range without the display being removed even by friction generated during the printing process due to the adhesion force of the paint provided by the printing process on the special treatment layer. The printing workability is also excellent.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0021]
As shown in FIG.1 and FIG.2, the synthetic resin sheet 1 which can remove the display of this embodiment has transparency, and the special process is given to the surface. Examples of the material of the synthetic resin sheet 1 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, polyester resin, and acrylic resin.
[0022]
On the surface of the synthetic resin sheet 1, special processing layers such as an antistatic function processing layer and antibacterial / antifouling function processing layer are sequentially laminated to form a multilayer special processing layer by gravure printing.
[0023]
On the surface of the special treatment layer, an explanation of the content of the special treatment is displayed 2 by a paint containing a pigment and a water-soluble resin, and the display 2 can be wiped off by wiping with water.
[0024]
This paint is prepared with 5-30% water-soluble resin, 5-30% pigment, 40-90% solvent and auxiliary agent, and scales representing letters, figures, quantities, etc., indicating the effects and functions of the special treatment. Is printed by a gravure printing method or a flexographic printing method.
[0025]
Examples of the water-soluble resin of the paint include polyvinyl alcohol resin, acrylic resin, and cellulose resin.
[0026]
The mixing amount of the water-soluble resin varies depending on the printing technique and physical properties, but is preferably in the range of about 10 to 20% in the gravure printing method and the flexographic printing method. If it is within this range, the adhesion of the paint to the special treatment layer provided by printing is ensured and the display 2 is not often removed even by friction generated during the printing process, and the viscosity of the paint is also within an appropriate range. Excellent printing workability.
[0027]
As the pigment, organic or inorganic pigments can be used, and chromatic or achromatic pigments can be used. The mixing amount of the pigment varies depending on the printing method, physical properties, or the role of the contents of the display 2 (the degree of concealment of the design of the synthetic resin sheet 1), but about 10 to 10 when printing by the gravure printing method or the flexographic printing method. 20% is desirable. If it exceeds about 30%, the concealability of the design pattern is improved, but the viscosity of the coating tends to increase and the printing workability tends to decrease.
[0028]
As the auxiliary agent, a surfactant or alcohol is desirable.
[0029]
As shown in Fig. 2, the display 2 of the description of the content of the special treatment includes the presence of a special treatment surface (such as "Antistatic, antibacterial and antifouling treatment is applied"), the effectiveness of the special treatment, Examples of functions, usage notes, etc. that are clearly shown to consumers etc. by letters and illustrations. For example, as a precaution in use, it is possible to display 2 such as “Please wipe the description with wet wipes”.
[0030]
Also, as shown in FIG. 1, as a display 2 for explaining the contents of the special processing, etc., when the synthetic resin sheet 1 is cut at the time of purchase, it is shown for every fixed unit (for example, cm unit or m unit). And the like can be exemplified. If it does in this way, the synthetic resin sheet 1 displayed by the roll shape 3 on the display frame 4 can eliminate the troublesome trouble of measuring a required length using a tape measure etc. at the time of sale.
[0031]
Next, the use state of the synthetic resin sheet 1 from which this display can be removed will be described.
[0032]
Since this synthetic resin sheet 1 has a description 2 on the surface of the description of the contents of the special processing, the description of the contents of the special processing can be grasped from the sheet surface itself, and the contents of the processing performed And the explanation of the function is easier to understand at the time of sale. That is, the purchaser of this synthetic resin sheet 1 can easily grasp the efficacy and function of the sheet.
[0033]
The display 2 is made of a paint containing a pigment and a water-soluble resin, and can be wiped off by wiping with water, so that it can be erased by wiping with water. Therefore, the consumer who understands the effect and the function can wipe off easily the display 2 of the explanation which became unnecessary when actually using it with the wiping cloth 5 containing water. The paint forming the display 2 is dissolved in the moisture of the wet cloth 5. In addition, when attaching a pattern (not shown) to synthetic resin sheet 1 itself, it is good not to drop by water wiping.
[0034]
That is, a printing paint that can be easily removed is developed, and the effect, function, scale, or the like of special treatment applied to the synthetic resin sheet 1 is printed by using this, so that the synthetic resin sheet 1 can be purchased at the time of purchase. It is possible to easily grasp the effects and functions of the. Moreover, after grasping the efficacy and function, the unnecessary explanation display 2 when used as a transparent sheet can be easily turned off.
