Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium for producing a mouse pad suitably used for printing by ink-jet printing, a mouse pad kit comprising the recording medium and a resin sheet, and a method for producing a mouse pad using the same.

[0002]

2. Description of the Related Art Ink jet recording methods include various ink discharge methods, for example, an electrostatic suction method, a method of applying mechanical vibration or displacement to ink using a piezoelectric element, and heating and bubbling ink to utilize the pressure. In this method, small ink droplets are generated and fly, and some or all of them are attached to a recording material such as paper or a plastic film coated with an ink receiving layer to perform recording. It has attracted attention as a method that can perform high-speed printing and multicolor printing with little noise.

[0003] As inks for ink jet recording, those mainly composed of water are used mainly from the viewpoints of safety and recording characteristics, and polyhydric alcohol is used for preventing nozzle clogging and improving discharge stability. In many cases.

Conventional recording media used for ink-jet recording are described in JP-A-63-220177, JP-A-5-221112, JP-A-5-262028, and JP-A-7-1828. As described above, a recording sheet provided with an ink receiving layer made of acetal-modified polyvinyl alcohol is disclosed in JP-A-62-831.
No. 78 and Japanese Patent Application Laid-Open No. 6-92011 have proposed a recording sheet containing fine silica particles.

In recent years, personal computers have spread,
A mouse is used as information input means. Since a mouse is inexpensive and easy to use as a pointing device, many users use it as an input device of a computer.

When inputting to a computer using a mouse, the movement of the pointer on the monitor and the movement of the trackball (ball in the mouse) are linked, so that the movement of the hand (the movement intended by oneself) is the same as that of the hand. If the trackball doesn't rotate correctly, you won't be able to type correctly on your computer. Therefore, the surface in contact with the trackball is made of woven fabric, planted with hair, or provided with some unevenness.

For example, Japanese Patent Application Laid-Open No. 9-006528 proposes a mouse pad having a specified fiber diameter, and Japanese Patent Application Laid-Open No. 7-295574 proposes a sheet material used for the mouse pad. 8-123616
Japanese Patent Application Laid-Open No. Hei 5-17733 discloses a mouse pad with a trackball cleaner, and Japanese Unexamined Utility Model Publication No. Hei. Each mouse pad provided is proposed.

[0008]

In recent years, the environment surrounding an ink jet printer has been drastically changed. For example, paper, coated paper, or OHP sheets are not used for documents and presentations, but are used for personal enjoyment. There has been a growing demand for inkjet recording media.

[0009] There is an increasing demand for the only thing in the world that is suitable for one's personal preference and that is used by oneself.

However, there has been no ink jet recording medium which can easily produce an original mouse pad by itself, which can be sufficiently satisfied by the conventionally proposed ink jet recording medium. Furthermore, no mouse pad kit has been proposed so far that allows the user to easily create an original mouse pad by himself.

[0011] For example, as a recording medium of the prior art illustrated, Japanese Patent Application Laid-Open Nos.
The recording media described in JP-A-1112, JP-A-5-262028, JP-A-7-1828, JP-A-62-83178, and JP-A-6-92011 are used as recording media for inkjet. Can be used, but when used as a recording medium for a mouse pad, visibility, image clarity, trackball rolling,
It is not satisfactory in any point, such as durability (deterioration of the surface due to friction with a trackball) and adhesiveness with an adhesive.

Japanese Patent Application Laid-Open No. Hei 9-006528, which has been exemplified as a conventional mouse pad, has a problem in durability since the surface in contact with the trackball is made of fiber and the surface is deteriorated by friction. JP-A-7-2955741
In the case where an ink receiving layer is provided on the mouse pad sheet material proposed in Japanese Patent Application Laid-Open Publication No. H11-157, it is not satisfactory in terms of difficulty in providing a uniform ink receiving layer and visibility, and a clear image cannot be obtained. Further, the mouse pad proposed in Japanese Unexamined Utility Model Publication No. 5-17733 does not satisfy ink absorbency.

As described above, no ink jet recording medium for making a mouse pad which can be easily made by ink jet printing has been proposed.

Further, there is no proposal for a mouse pad making kit which can be easily made by using the ink jet printing method. Of course, there is no proposal for a mouse pad making method using this kit.

An object of the present invention is to provide a recording medium for producing a mouse pad, which is capable of ink-jet printing and has excellent operability of a mouse.

Another object of the present invention is to provide a mouse pad kit that allows a personal computer user or the like to easily create an original mouse pad using a personal computer and an ink jet printer.

It is a further object of the present invention to provide a method for producing an original mouse pad using a mouse pad kit.

[0018]

The above objects are achieved by the present invention described below.

That is, the present invention is a recording medium for producing a mouse pad, characterized in that a transparent or translucent substrate has an ink receiving layer on one surface and a mat layer on the opposite surface. .

Further, the present invention is a kit for producing a mouse pad, comprising the above-mentioned recording medium and a resin sheet.

Further, the present invention is characterized in that the method further comprises a step of forming an image by applying ink to the ink receiving layer of the recording medium by an ink jet method, and a step of bonding a resin sheet to the ink receiving layer surface of the recording medium. This is how to create a mouse pad.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to preferred embodiments.

[Recording Medium for Making Mouse Pad] As shown in FIG. 1, the recording medium of the present invention has an ink receiving layer 3 on one surface of a transparent or translucent base material 2 and a surface opposite thereto. And a mat layer 1.

The ink receiving layer is preferably a resin layer containing an aqueous resin or a porous layer containing alumina hydrate.

The aqueous resin includes a water-soluble resin and a water-dispersible resin.

The water-soluble resin is not limited as long as it can accept a so-called aqueous ink and exhibits solubility or affinity with the aqueous ink. For example, unmodified polyvinyl alcohol, anion-modified polyvinyl Alcohol, cation-modified polyvinyl alcohol,
Acetal-modified polyvinyl alcohol, polyurethane,
Carboxymethylcellulose, polyvinylpyrrolidone,
Synthetic resins such as polyester, polyacrylate, hydroxymethylcellulose, melamine resin and modified products thereof; natural resins such as albumin, gelatin, casein, starch, cationized starch, acacia, sodium alginate and the like.

As the water-dispersible resin, polyvinyl acetate,
Ethylene-vinyl acetate copolymer, polystyrene, (meth) acrylate copolymer, styrene- (meth)
Acrylate copolymer, vinyl acetate- (meth) acrylate copolymer, poly (meth) acrylamide, (meth) acrylamide copolymer, styrene-isoprene copolymer, styrene-butadiene copolymer, ethylene- Examples include propylene copolymers, polyvinyl ethers, and silicone-acrylic copolymers. In addition, a copolymer containing units such as N-methylolacrylamide and having a self-crosslinking property may be used. Further, these plural aqueous resins may be used simultaneously.

Among these aqueous resins, ink absorption,
In consideration of the color developing property and the like, any one of polyvinyl alcohol, polyvinyl pyrrolidone, hydroxymethyl cellulose, polyvinyl acetal resin, polyester resin, and urethane resin, or a mixture thereof is suitably used.

On the other hand, examples of the alumina hydrate include crystalline boehmite (composition formula: AlOOH) and aluminum hydroxide (composition formula: Al (OH) ₃ ), and amorphous alumina hydrate. When the hydrate is composed of boehmite, a gel obtained by drying the sol is particularly preferable because it has good ink absorbability and excellent transparency.

The porous layer containing the alumina hydrate uses the above-mentioned aqueous resin as a binder, and the weight ratio of the alumina hydrate to the binder is preferably 1: 1 to 30: 1, more preferably 5: 1. It is formed by mixing and applying the mixture to the base material in a range of about 25: 1.

A cationic resin can be used in the ink receiving layer in order to improve image storability such as no migration of dye. As such a cationic resin, a cationic resin having a quaternary ammonium salt is preferable. For example, quaternary ammonium salt types such as monoalkylammonium chloride, dialkylammonium chloride, tetramethylammonium chloride, trimethylphenylammonium chloride, and ethylene oxide-added ammonium chloride are preferable. Resins. The reason why the image preservability is improved by adding such a cationic resin is not clear, but the anionic dye ionically bonds with the quaternized cation portion of the cationic resin to form an aggregate. It is considered that migration of the dye is suppressed.

Among these resins, a copolymer having a phenyl group, a naphthyl group, a benzyl group or a phenethyl group and a compound having a long-chain alkyl group (preferably having 10 to 30 carbon atoms) in a side chain is preferred. Coalescence is particularly preferred.
Since such a resin has a hydrophobic portion such as an aromatic ring and a long-chain alkyl group, it is hardly affected by humidity and the dye is hardly dissociated, so that the image storability can be further improved.

The proportion of the aqueous resin and the cationic resin is preferably 5 to 30 parts by weight based on 100 parts by weight of the aqueous resin. More preferably, it is 5 parts by weight or more and 25 parts by weight or less. Even when alumina hydrate is used, the same amount of the cationic resin as described above can be added to the solid content of alumina hydrate.

When the amount of the cationic resin is less than 5 parts by weight, the effect of adding the cationic resin tends to be insufficient in terms of image preservation. When the amount of the cationic resin is more than 30 parts by weight, the ink absorption tends to decrease, and the uniformity tends to decrease, and the border between different colors tends to blur. Also, when more than 30 parts by weight of the cationic resin is added to the alumina hydrate, the coating liquid tends to gel.

In order to adjust the hydrophilicity of the ink receiving layer,
Methylolated melamine, methylolated urea, methylolated hydroxypropylene urea, isocyanate, and the like can be used in combination, and these may contain a crosslinking agent.

In the ink receiving layer, various additives can be used together as long as the object of the present invention is not hindered.

Specific examples of the additives include various surfactants, various fillers, antifoaming agents, antioxidants, fluorescent brighteners, ultraviolet absorbers, dispersants, viscosity modifiers, pH regulators,
Fungicides and plasticizers. These additives may be arbitrarily selected from conventionally known compounds according to the purpose. It is also possible to use a plurality of these at the same time.

Further, various fine particles and further additives may be added in order to improve the blocking property, ink fixing property and ink absorbing property of the ink receiving layer.

Examples of the fine particles include silica, alumina, aluminum silicate, magnesium silicate, basic magnesium carbonate, talc, haodotalcite, calcium carbonate, titanium oxide, zinc oxide, and polyethylene, polystyrene, silicone, Plastic pigments such as polyacrylate are exemplified. Among these fine particles, it is preferable to use fine particles having an average particle size of 0.1 μm to 10 μm and a pore volume of 1.6 ml / g to 2.0 ml / g, preferably silica.

When the average particle size is smaller than 0.1 μm, the effect cannot be sufficiently exerted in terms of ink absorbency, blocking property and the like unless the mixing amount with respect to the resin component is increased, and the haze degree of the ink receiving layer is reduced. Some of them are not satisfactory in terms of image clarity and film strength of the ink receiving layer. Further, when the average particle size is 10 μm or more, the particle size is large, so that problems tend not to occur when the image sheet is not adhered neatly when bonded to the resin sheet after the image is formed, or the resin sheet and the sheet on which the image is formed are easily peeled off. is there.

When the pore volume is less than 1.6 ml / g, there is a tendency that the ink absorbency (particularly at the initial stage of printing) does not show sufficient performance. Anything greater than 2.0 ml / g is currently technically impossible to manufacture. However, it is considered that there is no problem if it can be technically manufactured.

Next, the material of the mat layer of the recording medium is not particularly limited as long as it is made of resin and fine particles having transparency at the time of film formation.

Examples of such a transparent resin include:
Butyral-modified polyvinyl alcohol, polyvinyl chloride, polyvinyl acetate, polystyrene, polyethylene, acrylic resin, cellulose, polycarbonate, phenoxy and the like. Among these, in consideration of transparency, workability, cost, etc., polymethyl methacrylate, (meth) acrylate copolymer, styrene- (meth) acrylate copolymer, vinyl acetate- (meth) acryl Acid ester copolymer, poly (meth)
Acrylic resins such as acrylamide and (meth) acrylamide copolymers are particularly preferred.

As the fine particles used in combination with the resin having transparency, the above-mentioned fine particles can be used. Among them, it is particularly preferable to use silicone or acrylic resin fine particles from the viewpoints of the difference in refractive index from the resin used, the transparency of the fine particles, and the solvent resistance.

In order for the mouse trackball to roll on the mat layer and the pointer on the monitor to move accurately as intended by the user, the mat layer preferably has a Beck smoothness of 10 seconds or less, more preferably. The time is 5 seconds or less, more preferably 2 seconds or less. If the Beck smoothness of the mat layer is more than 10 seconds, an appropriate frictional force tends to be hardly generated between the trackball and the mat layer, and the pointer on the monitor does not move exactly as intended by the user. That is, the track ball of the mouse may slide on the mat layer.

The weight ratio between the resin and the fine particles constituting the mat layer is in the range of resin / fine particles = 100/40 to 10
It is preferably in the range of 0/100, and more preferably in the range of 100/40 to 100/80.

The ratio of the resin and the fine particles constituting the mat layer is
If the solid content ratio is less than resin / fine particles = 100/40, there is a tendency that an appropriate frictional force does not easily occur between the trackball and the mat layer, and the pointer on the monitor can be accurately positioned as intended by the user. There is also a case where the mouse does not move, that is, the track ball of the mouse slides on the mat layer. When the ratio of the resin and the fine particles constituting the mat layer is larger than the resin / fine particles = 100/100 in the solid content ratio, the film strength of the mat layer is insufficient, and when the resin sheet and the recording medium are bonded to each other. The mat layer tends to crack, or the mat layer tends to crack or chip during use as a mouse pad.

Further, in order to generate an appropriate frictional force between the mat layer and the track ball of the mouse more efficiently, and to move the pointer on the monitor more precisely according to the user's intention, the fine particles protrude from the resin layer. Is preferred.

The haze degree of the recording medium must be 80 or more and 95 or less in consideration of the fact that the image formed on the ink receiving layer is observed through the ink receiving layer, the base material and the mat layer. Is preferred. When the haze degree is smaller than 80, the amount of fine particles filled in the mat layer or the ink receiving layer is small, and the performance of either layer tends not to be sufficiently achieved. On the other hand, if it is larger than 95, the image is difficult to observe clearly and a beautiful mouse pad cannot be created.

The substrate used in the present invention can be used without any problem as long as it has transparency or translucency.

As the base material used in the present invention, polyethylene terephthalate, diacetate, triacetate,
Examples include cellophane, celluloid, polycarbonate, polyimide, polyvinyl chloride, polyacrylate, polyethylene, polypropylene, and other plastic films, but are not limited thereto.

In preparing the ink-receiving layer of the recording medium of the present invention, the composition is first mixed with water or an alcohol, a polyhydric alcohol, or another suitable organic solvent, if necessary, together with other additives. Dissolved or dispersed in
Adjust the coating liquid.

The obtained coating solution is applied to a roll coater method, a blade coater method, an air knife coater method, a gate roll coater method, a bar coater method, a size press method, a spray coat method, a gravure coater method, a curtain coater method, etc. On the surface of the base material. Thereafter, drying is performed using, for example, a hot-air drying furnace, a hot drum, or the like to obtain the ink receiving layer of the recording medium of the present invention. Further, if necessary, a super calendering treatment or the like may be applied to smooth the ink receiving layer or increase the surface strength.

The coating amount (at the time of drying) of the ink receiving layer is preferably from 0.2 to 30 g / m ² , more preferably from 1 to 25 g / m ² . 0.2g /
When the amount is less than m ² , the effect is lower in terms of the coloring properties of the paint, the ink absorption capacity, and the ink fixability as compared with the case where the ink receiving layer is not provided, while the amount exceeds 30 g / m ^2. In particular, curling easily occurs in a low-temperature and low-humidity environment. When the coating amount is represented by the thickness, the coating amount is preferably in the range of 0.5 to 35 μm.

The coating amount (at the time of drying) of the mat layer is preferably about the same as the coating amount of the ink receiving layer in consideration of curling in a low-temperature and low-humidity environment. The absolute value of (layer coating amount)-(mat layer coating amount) is preferably 30 g / m ² or less, more preferably 20 g / m ² or less.

In forming the mat layer of the recording medium of the present invention, the same method as described above may be used.

[Resin Sheet for Making Mouse Pad] FIG.
Shows a preferred configuration of a resin sheet for producing a mouse pad used in the present invention, in which a release paper 4 is provided on a resin sheet 6 via a re-peelable processing layer 5.

The resin constituting the resin sheet for preparing a mouse pad used in the present invention includes urethane resin, acrylic resin, phenol resin, polyester resin, fluororesin, polyacetal resin, epoxy resin, polyvinyl chloride, and polyethylene resin. , Silicone resin, polyolefin resin, alkyd resin, butadiene synthetic rubber,
A large number such as natural rubber or the like alone or as a mixture can be listed, but the present invention is not limited thereto. Further, those obtained by foaming these materials, or those obtained by mixing glass fibers or the like to improve the strength of the resin sheet can be used.

Since the mouse pad is used on a desk or the like, the mouse pad does not move during use, is excellent in workability, and is a polyethylene resin capable of reducing the thickness of the resin sheet.
It is more preferable to use urethane resin, silicone resin, polyvinyl chloride alone or in combination, or natural rubber or synthetic rubber.

When using not a resin sheet but a very hard and inflexible material such as glass (plate), acrylic (plate), plastic (plate), wood (plate), and poor adhesion to a desk, In order to improve the adhesiveness with the desk, a resin which has been subjected to processing of the resin, processing of slight adhesion or light peeling, suction cup processing, or the like may be used in order to increase the adhesiveness with the desk.

In order to easily create an original mouse pad, it is necessary that at least one surface of the resin sheet be re-peelable as a means for bonding the resin sheet to the recording medium.

As a re-peelable processing means, there is a method in which the surface of the resin sheet is finely formed into a sucker state, or a re-peelable adhesive is applied.

As an example in which the surface of the resin sheet is made into a sucker state by microporing, a fine chain-shaped sucker layer is provided on the entire or a part of the application surface. As a method, a vinyl resin, a urethane resin, a silicone resin, an ultraviolet curable resin or other synthetic resin as a base material, and an ink-like substance which becomes a flexible sucker after being printed by a method such as screen printing. There is a method of installing a sucker layer of a sucker type pattern having an arbitrary shape, and these methods can be used as appropriate. Of course, it is not limited to these methods.

As the removable adhesive, those conventionally used can be used as appropriate.

In order to minimize the incorporation of bubbles (air) at the time of lamination with the recording medium, it is preferable to form regular irregularities on the removable pressure-sensitive adhesive layer. As an example of the method of providing the unevenness, there is a method of bonding a release paper having a regular unevenness after providing the pressure-sensitive adhesive layer, and forming the adhesive layer with the regular unevenness, but is not limited thereto. .

As a component of the removable pressure-sensitive adhesive, a plasticizer, a tackifying resin or a silicone compound is blended with an elastic material such as natural rubber or synthetic rubber or an acrylic resin to suppress an increase in adhesive force with time. In addition, a material whose removability is facilitated can be used. Further, a copolymer obtained by copolymerizing a silicone-based monomer, a copolymer containing a silicone-based macromonomer as a component, and a re-peelable pressure-sensitive adhesive of a copolymer obtained by grafting a polysiloxane resin can also be used.

Examples of the acrylic pressure-sensitive adhesive include ethyl acrylate, propyl acrylate, n-butyl acrylate, isobutyl acrylate, n-octyl acrylate, isooctyl acrylate, 2-ethylhexyl acrylate, nonyl acrylate, isononyl acrylate and lauryl acrylate. Butyl methacrylate, n-octyl methacrylate, isooctyl methacrylate, 2-ethylhexyl methacrylate, nonyl methacrylate, isononyl methacrylate, lauryl methacrylate and other acrylates, methacrylate as a main component, these monomers, methyl acrylate,
Methyl methacrylate, ethyl methacrylate, propyl methacrylate, isobutyl methacrylate, vinyl acetate, vinyl versatate, ethylene, styrene, acrylonitrile, vinyl chloride, acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic acid, maleic anhydride, fumaric acid , Acrylamide, methacrylamide, N-methylol acrylamide, N-methylol methacrylamide, glycidyl acrylate, glycidyl methacrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl acrylate, 2-hydroxypropyl methacrylate, tetraacryloxy Copolymerizes ethane, triallyl cyanurate, triallyl isocyanurate and other monomers It is obtained by a, but the present invention is of course not limited thereto.

The coating amount of the removable adhesive layer or the suction cup layer is ^{2 to} 80 g / m ² , preferably ² to 50 g / m ² ,
More preferably, it is in the range of 5 to 40 g / m ² . When the coating amount is less than 2 g / m ² , the adhesion to the recording medium tends to be insufficient. When the coating amount is more than 80 g / m ² , the effect of increasing the coating amount tends to be hardly obtained in terms of adhesion to a recording medium.

Regarding the size of the recording medium for preparing the mouse pad and the size of the resin sheet used in the present invention, it is preferable that the size of the recording medium is larger than the size of the resin sheet because an image can be arranged on the entire surface of the resin sheet.

Known inks can be used for printing on the recording medium described above.

As the recording agent, direct dyes, acid dyes, basic dyes, reactive dyes, water-soluble dyes represented by food dyes, and disperse dyes and pigments can be used.

Such water-soluble dyes or dispersible dyes and pigments are generally used in conventional inks at about 0.1%.
It is used in a proportion occupying up to 20% by weight, and this proportion may be the same in the present invention.

The solvent used in the water-based ink used in the present invention is water or a mixed solvent of water and a water-soluble organic solvent. Particularly preferred is a mixed solvent of water and a water-soluble organic solvent, It contains a polyhydric alcohol having an effect of preventing ink from drying as an organic solvent.

The method for applying the above-mentioned ink to the recording medium to perform recording is preferably an ink jet recording method. In this method, the ink is effectively released from the nozzles and the ink is applied to the recording medium. Any method may be used as long as the method can give.

In particular, according to the method described in Japanese Patent Application Laid-Open No. 54-59936, the ink that has been subjected to the action of thermal energy causes a sudden change in volume, and the ink is ejected from the nozzle by the action force resulting from this state change. The ink jet method used can be used effectively.

As shown in FIG. 3, the method for producing a mouse pad according to the present invention is to apply an ink to the ink receiving layer 3 of a recording medium to form an image 7, and then remove the separator from the resin sheet 6 to remove the ink. It is to be attached to a layer. Since the image is observed from the mat layer side, when printing characters, it is necessary to perform mirror image printing.
