Abstract

<P>PROBLEM TO BE SOLVED: To solve problems of a conventional mouse pad that the response of the mouse is deteriorated because dust, oil or the like is accumulated on a sensor of the mouse via a mouse ball because a film or synthetic resin is used on the front surface layer in contact with the mouse ball, and that an exclusive space has to be secured in using the mouse pad on a desktop because of the thickness of the mouse pad as many existing mouse pads are of the multi-layered type consisting of a surface layer, elastic layer and a non-slip layer. <P>SOLUTION: The base material of the mouse pad is transparent paper made of paper material whose main raw material is wood pulp with the beating degree of 300 ml (CSF: JIS P 8121) or lower, and an adhesive layer is disposed on one surface of the base material to bond the base material to the mouse pad. The adhesive layer is disposed after images are formed on one surface by printing, and therefore, the mouse pad can transmit information. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse pad used for a mouse used for inputting data or the like into a personal computer, and has a release paper on the back surface, and the release paper is peeled off to a desired location. The present invention relates to a mouse pad that is attached to and used. Especially, the mouse pad is most suitable for a ball-type mouse.

[0002]

2. Description of the Related Art In general, a ball-type mouse is often used for operations such as data input to a personal computer. A mouse pad is used for the purpose of improving the responsiveness of the ball-type mouse, and a film layer or a resin layer is provided on the contact surface with the mouse as a measure for improving the responsiveness, and an elastic layer is further provided under the mouse in general. It is used. Further, there has been proposed one in which a non-slip rubber sheet layer is provided on the contact surface of the desk with the top plate. The elastic layer of the mouse pad is disclosed in combination with the surface film layer in Japanese Utility Model Laid-Open No. 4-44037 and Japanese Patent Application Laid-Open No. 9-280992. Further, Japanese Patent Laid-Open No. 2000-259344 proposes a mouse pad having an image forming ability by sublimation thermal transfer.

[0003]

However, in the above-mentioned mouse pad, since the film or resin layer is used as the surface layer which comes into contact with the mouse, fibrous dust, sebum, etc. may be removed from the mouse ball during use. There is a problem that the responsiveness is lowered by depositing on the sensor of the mouse via the. Also, although the rubber sheet material has a great anti-slip effect, it must be adhered to the desk top plate when in use.
There are cases in which the effect cannot be fully exerted, such as being affected by the material and surface quality of the top plate, or being difficult to use on an inclined part. Furthermore, many existing mouse pads have a surface layer, an elastic layer, and an anti-slip layer, and have a multi-layered type, and when used on a desk, there is a problem that a dedicated space needs to be secured due to their thickness.

[0004]

The mouse pad of the present invention has a beating degree of 300 ml (CSF: JIS P 812).
1) A mouse pad in which a transparent paper made from a paper material containing the following wood pulp as a main material is used as a base material and an adhesive layer is provided on one surface thereof. Preferably, the transparency (ISO-2471) of the substrate is 40% or more, or the smoothness (ISO-5627) of the substrate is 10 seconds or more and 120 seconds or less. Further, in the mouse pad of the present invention, it is preferable that an adhesive layer is provided on one surface of the base material after image formation by printing on one or both surfaces of the base material, and the base material is preferably colored with a dye.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The base material used in the mouse pad of the present invention is, as pulp, LBKP, NBKP, LB.
Examples thereof include SP, NBSP, and various bleached non-wood pulps. In use, they can be used alone or as a mixture of several kinds in a ratio according to the purpose. Also,
Wood pulp is the main component, and various types of chemical pulp and recycled pulp are used as wood pulp, and the beating degree is 3 with a beating machine.
It is used after adjusting to less than 00 ml (CSF: JIS P8121). The beating degree of pulp is 300 ml
Or less, preferably 200 ml or less, more preferably 1
The amount is preferably 00 ml or less, and the higher the beating, the higher the transparency and the stronger the paper strength.

In the base material of the present invention, beating of pulp can be carried out by using a beating machine such as a double disc refiner, a deluxe finer, or a Jordan used in general papermaking. Further, as the beating conditions of the pulp used in the present invention, viscous beating (mainly fibrillation) is more dominant than free beating (pulp fiber cutting is the main component). It is preferable from the point.

That is, the pulp used in the present invention is a pulp that has been beaten by a high degree of viscous beating until sufficient internal fibrillation and external fibrillation occur, and the highly beaten pulp is used as a wire for a paper machine. The mouse pad base material can be obtained after sufficient dehydration and sufficient water squeezing with a press, while controlling shrinkage due to drying with a dryer, and carefully drying so as not to cause rapid drying.

Conventionally known sizing agents, paper strength enhancers, retention aids, dyes, optical brighteners, etc. can be added to the base material of the present invention as auxiliary agents. It can be manufactured with various machines such as paper machines and twin wire paper machines. Further, in the size press step of the paper machine, starch, polyvinyl alcohol and the like can be impregnated and applied to adjust the surface strength, size and the like, and a surface sizing agent and the like may be added as necessary.

Further, in the mouse pad of the present invention, since the base material is dyed with a dye, it is possible to give a transparent feeling and a coloring feeling. The dye is mixed in the pulp slurry to obtain a uniform single color, and it is also possible to dye only one side of the substrate by the size pressing step or the like,
It can be appropriately adjusted according to the application.

The smoothness of the base material of the present invention is preferably 10 to 120 seconds, more preferably 30 to 60 seconds. Within this range, it becomes possible to balance the ability to hold dirt such as dust and sebum between the fibers on the surface of the base material and the operability of the mouse.

For the purpose of controlling the smoothness of the substrate, calendering may be carried out as the surface treatment. However, if the smoothness exceeds 120 seconds, dust, sebum, etc. do not stop on the surface of the base material and are transferred to the sensor via the mouse ball.
If the smoothness is less than 10 seconds, the smoothness of the base material is impaired, and smooth operation is hindered when the mouse is used.

The substrate of the present invention can be printed on one side or both sides. Regarding printing, multicolor printing by plate making method, for example, offset method or gravure method printing, non-impact method, that is, toner fixing method (electrophotography, laser printer, etc.), or various printing methods such as inkjet method It is possible to print.

In the mouse pad of the present invention, information can be transmitted by forming an image on the substrate by printing and then providing an adhesive layer. In the present invention, in the case of single-sided printing, it is preferable to provide an adhesive layer on the printed surface. The image seen through the base material is not only good-looking, but also useful because the printed portion is not scraped off by the mouse.

An ink jet recording method is preferred when an adhesive layer is provided on the opposite side of single-sided printing or for printing on the side where no adhesive layer is provided in double-sided printing. In particular, when printing with a dye-type ink, the ink permeates the base material, and the printed portion itself is unlikely to fall off. A normal printing ink is not preferable because it covers the surface and the ink-printed portions may collectively fall off due to friction with the mouse.

The mouse pad of the present invention is used by pasting the above-mentioned base material with an adhesive layer provided thereon. The pressure-sensitive adhesive layer is provided by applying the following pressure-sensitive adhesive to the release agent-coated surface of the release sheet, drying it, and then pressure-bonding it to the substrate with a press roll. Also,
After the adhesive layer is applied to the substrate and dried, pressure may be applied with a press roll so that the release agent-coated surface of the release sheet is in contact with the adhesive layer. In the present invention, as the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer, a main monomer component having a low glass transition temperature that imparts tackiness, a comonomer component having a high glass transition temperature that imparts adhesiveness or cohesive force, crosslinking or adhesion A polymer or copolymer containing a functional group-containing monomer component or the like for improving the properties as a main component can be used. These polymers are
Used by adding a crosslinking agent.

The main monomer components include ethyl acrylate, butyl acrylate, amyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, cyclohexyl acrylate, benzyl acrylate, and other alkyl acrylates, and butyl methacrylate. Alternatively, methacrylic acid alkyl esters such as 2-ethylhexyl methacrylate, cyclohexyl methacrylate, and benzyl methacrylate can be used.

As the comonomer component, methyl acrylate, methyl methacrylate, ethyl methacrylate, vinyl acetate, styrene, acrylonitrile and the like can be used. As the functional group-containing monomer component, carboxyl-containing monomers such as acrylic acid, methacrylic acid, maleic acid, itaconic acid, crotonic acid, 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, N -A hydroxyl group-containing monomer such as methylol acrylamide, acrylamide, methacrylamide, glycidyl methacrylate or the like can be used.

The pressure-sensitive adhesive used in the present invention is used by adding a crosslinking agent to the polymer or copolymer solution of the above-mentioned monomer components. As the cross-linking agent, an isocyanate type,
It is selected from those capable of reacting with functional groups such as epoxy type, ethyleneimine type, and aluminum chelate type, and used.

In the present invention, the coating amount (dry weight) of the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer is preferably 20 g / m ² or less, more preferably 15 g / m ² or less. The smaller the coating amount, the less the trouble of sticking out the adhesive.

Since the mouse pad of the present invention is used by being stuck with an adhesive layer, it is preferable that the mouse pad does not easily come off, and the adhesive strength is 3.9 N / 25 mm or more, preferably 7.8 N / 25 mm or more. . Adhesive strength is 3.9
If it is less than N / 25 mm, when it is used by being stuck on a desk or the like, it may be curled up due to curling of the substrate or contact with a document or the like.

As an apparatus for providing the adhesive, an air knife coater, a blade coater, a bar coater, a roll coater, a slot nozzle, a slot die, a rotary screen printer, a gravure coater, an offset gravure coater, a hot melt wheel, a spiral spray, etc. The type may be selected according to the application, such as the type and amount of the adhesive, the necessity of applying a pattern to the coated adhesive, and the like.

The base material of the release paper includes high-quality paper, kraft paper, glassine paper, plastic film and the like, and a silicone resin is applied as a release agent on these base materials. In the case of a paper base material, a thermoplastic resin may be laminated on the base material before use. Further, when it is necessary to secure the curl suitability, it is preferable to laminate a thermoplastic resin or coat a synthetic resin on the opposite surface of the base material coated with the silicone resin as a back surface treatment. A non-silicone release agent may be used for special purposes.
