Description

  The present invention relates to a writing structure having a writing surface on which writing can be repeated.

  A writing sheet having an ink-impermeable writing surface is known. For example, in Patent Document 1, a writing area where writing and erasing are performed is coated with a first coating layer coated with an ultraviolet curable first top coat and an ultraviolet curable second top coat. A writing paper with a second coating layer is described.

Japanese Patent No. 4519184

The inventor has obtained the following recognition regarding conventional writing paper.
In the writing paper described in Patent Document 1, a so-called acrylic plastic material such as an acrylic monomer and an oligomer is coated on the writing surface. In writing paper with a writing surface made of such an acrylic material, after a long time has passed since writing a character, etc. with a writing instrument, even if it is wiped off with an eraser, `` unerased '' remains where the ink of the writing instrument remains on the writing surface There are things to do. If such unerased items are stacked, the writing surface will eventually become dirty, and the readability of written characters will deteriorate. In addition, in such a printed copy of the writing surface, it may be impossible to determine the written content when it is read back later. In addition, the aesthetic appearance of the writing surface is deteriorated and the user may feel uncomfortable. From this, the inventor has recognized that there is room for improvement in terms of improving the “erasability” by reducing the amount of unerasable in the conventional writing paper.

  It is also conceivable to coat a fluororesin or the like to improve erasability. However, when a fluororesin is coated, there is a problem that writing becomes difficult depending on the type of ink of the writing instrument. In addition, there is a problem that the cost is likely to increase because extra work is required to coat the fluororesin.

  In addition, it is conceivable that the writing paper coated with an acrylic material has a large environmental load at the time of disposal. In other words, acrylic materials generate harmful gases when incinerated, and can remain semi-permanently when discarded in the natural environment, causing environmental pollution. Such a problem is not limited to acrylic materials, and may occur in other plastic materials as well. Furthermore, there is a concern that the plastic may be broken into micro plastics and diffused into the environment and taken into wildlife. In particular, when applying writing paper to various uses, reducing the environmental load is an urgent issue. From this, the inventor has recognized that there is room for improvement in the conventional writing paper from the viewpoint of reducing the environmental load at the time of disposal.

  An object of the present invention is to provide a writing structure that can improve erasability.

  In order to solve the above-described problems, a writing structure according to an aspect of the present invention is a writing portion that can be repeatedly written, and includes a cellophane writing portion made of a cellophane film.

  According to this aspect, the erasability can be improved by providing the cellophane writing unit.

  Note that any combination of the above-described constituent elements and the constituent elements and expressions of the present invention replaced with each other among methods, apparatuses, systems, and the like are also effective as an aspect of the present invention.

[First Embodiment]
The first embodiment according to the present invention is a writing sheet. FIG. 1 is a plan view showing a writing sheet 100 according to the first embodiment. FIG. 1 is partially cut away to show the internal structure. The writing sheet 100 is a sheet-like material having a writing structure capable of repeatedly writing characters and drawings. The writing sheet 100 is a writing unit made of a cellophane film, and includes a cellophane writing unit 104 capable of writing repeatedly. In particular, the writing sheet 100 is provided with a cellophane writing unit 104 made of a cellophane film on a base sheet 102 which is a base material. The writing sheet 100 mainly includes a base sheet 102, a bonding layer 106, and a cellophane writing unit 104. The cellophane writing unit 104 is attached to the base sheet 102 via the bonding layer 106.

(Base sheet)
The base sheet 102 is a base material that supports the cellophane writing unit 104. In particular, the base sheet 102 is a sheet material having a white or colored surface. One surface (back surface) of the cellophane writing unit 104 is attached to the base sheet 102. The base sheet 102 provides the cellophane writing unit 104 with a certain degree of rigidity and a predetermined background color and background display. The base sheet 102 can be formed from plant-derived materials such as paper or paperboard, wood-derived materials such as cork, various materials such as resin (including foamed resin) or metal. In the base sheet 102 of the embodiment, at least a portion that supports the cellophane writing unit 104 is a paperboard formed from a paper pulp that is a plant-derived material. The base sheet 102 has a thickness dimension smaller than a vertical dimension (Y-axis direction dimension) and a horizontal dimension (X-axis direction dimension). The base sheet 102 can be made of materials having various thicknesses. As an example, the base sheet 102 in the embodiment is a 0.4 mm (360 g / square meter) paper sheet. By using such a base sheet, the writing sheet 100 becomes thin and light, has a flexibility that can be easily deformed by a human hand, and can be applied to a wide range of applications.

  The writing surface of the writing sheet 100 may be colored. For example, by forming the base sheet 102 from a colored sheet or by applying a colored material (for example, paint) to the base sheet 102, the surface color appears on the writing surface through the cellophane writing unit 104. The writing surface can be realized. The cellophane writing part 104 is formed in color, so that the beauty can be improved. Since the erasability is good, a decrease in aesthetics can be suppressed even when used repeatedly.

  The base sheet 102 that is the base material may be provided with a display that is visible through the cellophane writing unit 104. Specifically, a base display such as a character or a pattern may be provided in an area where the cellophane writing part 104 of the base sheet 102 is formed. Since the cellophane film has high transparency, this base display can be clearly seen through the cellophane writing part 104. For example, by making the cellophane writing unit 104 share common contents such as a frame as a base display, it is possible to reduce the trouble of writing again. As an example, the base display may be formed by printing means such as offset printing. Such background display can also be applied to second to seventh embodiments described later.

(Cellophane writing department)
The cellophane writing part 104 is formed from a cellophane film. The thickness of the cellophane writing unit 104 is made smaller than the thickness of the base sheet 102. As an example, the thickness of the cellophane film used for the cellophane writing unit 104 may be 18 μm (26 g / square meter) to 25 μm (36 g / square meter). A predetermined unevenness may be provided on the writing surface of the cellophane writing unit 104.

  As an example, the cellophane film constituting the cellophane writing part 104 is formed by thinly forming viscose produced by dissolving pulp with an alkali such as sodium hydroxide and carbon disulfide through a slit and neutralizing with an acid such as sulfuric acid. And it can manufacture by returning to cellulose. The cellophane film produced in this way is a film mainly composed of regenerated cellulose.

  The cellophane writing unit 104 may be transparent, translucent, or opaque. The cellophane writing unit 104 may be colorless or colored. The cellophane writing portion 104 of the embodiment is substantially colorless and transparent or translucent. The colored cellophane writing part can be realized by a method of mixing a colored material into the cellophane film or by applying a colored material (for example, paint).

(Bonding layer)
The bonding layer 106 is a bonding means for bringing the cellophane writing part 104 into close contact with the base sheet 102. There is no particular limitation on the configuration of the bonding layer 106 as long as the cellophane writing unit 104 can be in close contact with the base sheet 102. For the bonding layer 106, for example, a water-based adhesive can be used. As a typical example, this adhesive may contain an ethylene-vinyl acetate copolymer type adhesive as a main component. The thickness of the bonding layer 106 is made smaller than the thickness of the cellophane writing part 104. As an example, the thickness of the bonding layer 106 may be 1 μm to 5 μm. The cellophane writing unit 104 may be fixed to the base sheet 102 by applying pressure in the thickness direction while heating while being superimposed on the bonding layer 106 applied to the base sheet 102.

  Next, the erasability of the writing sheet 100 configured as described above will be described. FIG. 2 is a diagram showing an experimental result regarding erasability of the writing sheet 100. FIG. 2 shows the result of comparing the material constituting the writing surface and its erasability. In this experiment, Comparative Example 1 to Comparative Example 6 having a writing sheet 100 and a writing surface made of another material are used as samples. Comparative Example 1 has a writing surface composed of a coating film using an acrylic monomer. Comparative Example 2 has a writing surface made of polyvinylidene fluoride. Comparative Example 3 has a writing surface made of a PVA (polyvinyl alcohol) -coated OPP (oriented PolyPropylene) film. Comparative Example 4 has a writing surface made of a PMP (polymethylpentene) film. Comparative Example 5 has a writing surface made of a PBT (Polybutylene terephthalate) film. Comparative Example 6 has a writing surface made of a nitrocellulose film.

  In the experimental method, the erasability of the notation formed by 15 types of markers (writing tools), each of which is different from each other, was examined over time. The elapsed time was 1 day, 3 days, 1 week, 2 weeks, 3 weeks, and 4 weeks after that day. In the evaluation, the eraser was pressed against the writing surface with a constant load to make one reciprocation, and the erased state of the marker notation was recorded in numerical expression. Evaluation is 1 when all 15 types of marker notations are erased, 2 when 1 to 4 types of marker notations remain unerased, and 3 when 5 to 10 types of marker notations remain unerased, When 5-10 types of marker notations remain unerased and 4 is particularly noticeable, 4 indicates that 11-14 types of marker notations remain unerased, and 5 indicates when all 15 types of marker notations remain unerased. It was set to 6. That is, evaluation 1 has the highest erasability and evaluation 6 has the lowest erasability.

  As a result of the experiment, all of Comparative Examples 1 to 6 showed unerased residue with one or more types of marker notation after 3 days, and unerased with 5 to 10 types of marker notation after 3 weeks. On the other hand, in the writing sheet 100, in any evaluation from the day to 4 weeks later, no unerased residue was observed in all 15 types of marker notations, and the erasability was good. In particular, in the comparative example, the unerased marker notation increased significantly after 4 weeks, whereas the writing sheet 100 did not show a significant increase in unerased at least within this period.

  Next, the reason why the erasability of the writing sheet 100 is excellent will be described. As the marker, an ink in which a pigment, a resin serving as a binder thereof, and a release agent are dissolved in a solvent such as alcohol is used. Therefore, the marker notation is a coating of the pigment left after the solvent is volatilized from this ink. This film is adhered to the writing surface in a non-adhering state by the release agent, and is easily peeled off by rubbing with an eraser. However, with the passage of time, it is considered that a part of this pigment soaks between the molecules of the material on the writing surface, resulting in unerased residues. It is also possible that part of the dye soaked in remains with the material molecules.

  The cellophane film constituting the cellophane writing part has a high molecular density and a small gap between the molecules, so that it is difficult for the dye to penetrate between the molecules. In addition, the surface of the cellophane film has a low free energy and is in a stable state, and it is considered that molecular bonds are hardly generated. As a result, it is considered that good erasability is achieved by maintaining a state in which the pigment adheres to the writing surface in a non-adherent state.

Next, an application example of the writing sheet 100 configured as described above will be described.
The writing sheet 100 can be processed to a predetermined size and applied to drawing paper, POP advertising paper, or price cards. Since the erasability is good, there is little unerased ink even after repeated use, and durability can be improved. Similarly, the writing sheet 100 may be attached to furniture such as a desk, a shelf, or a partition. The writing sheet 100 can be applied to furniture with a writing sheet. The writing sheet 100 may be attached to a stationery such as a major / ruler, a desk mat, or a mouse pad. The writing sheet 100 can be applied to a stationery with a writing sheet. The writing sheet 100 may be attached to a fan or a fan. The writing sheet 100 can be applied to a fan or a fan with a writing sheet. The writing sheet 100 can be applied to sticky notes, indexes, clips, and spines. They can write notes repeatedly. In addition, when applying to these, it is not essential to provide the base sheet 102, and the cellophane writing part 104 may be directly affixed to these application examples.

  Next, the effect of the writing sheet 100 comprised in this way is demonstrated.

  In the writing sheet 100 of 1st Embodiment, since it is a writing part which can be written repeatedly and is equipped with the cellophane writing part 104 which consists of a cellophane film, it suppresses the fall of the beauty | look by improving erasability and using it repeatedly. Can do. In addition, the cellophane writing unit 104 has biodegradability and can reduce the environmental load at the time of disposal. That is, it is possible to provide a writing medium that can achieve both good erasability and biodegradability.

  Since the writing sheet 100 of the first embodiment includes the base sheet 102 that is a base material that supports the cellophane writing unit 104, the cellophane writing unit 104 can be provided with a desired rigidity.

  In the writing sheet 100 of the first embodiment, since the cellophane writing unit 104 is attached to the base sheet 102 that is a sheet material, the cellophane writing unit 104 is not displaced from the base sheet 102 during writing, and the handling of the writing sheet 100 is performed. Becomes easier. Moreover, it is advantageous for weight reduction. In addition, since the cellophane writing unit 104 can be manufactured by sticking to the base sheet 102, the manufacturing effort is reduced as compared with the case where a plurality of overcoats are coated on top of each other as in the writing paper described in Patent Document 1. be able to.

  In the writing sheet 100 of the first embodiment, the base sheet 102 that is a base material is provided with a ground display that can be seen through the cellophane writing section 104, so that the base display can be displayed through the cellophane writing section 104. For example, by making common content such as a frame transparent as a background display, it is possible to reduce the trouble of repeatedly writing this content.

  In the writing sheet 100 of 1st Embodiment, since the base sheet 102 which is a base material is formed from the paper pulp which is a plant-derived raw material at least, the part which supports the cellophane writing part 104 shall have biodegradability.
