Description

  The present invention relates to a transfer film for a writing tool, a method for manufacturing a transfer film for a writing tool, a writing tool, and a method for manufacturing a writing tool.

  Pencils such as pencils tend to slip when the gripping surface is smooth, and may become fatigued when used for a long time. For this reason, the writing tool may be subjected to anti-slip processing on the gripping surface. Conventionally, such anti-slip processing has been performed by a method of applying a paint to form a rubber-tactile coating film or a method of coating a foamable resin.

  However, the conventional method has a problem in that it cannot increase the degree of freedom of design of the writing tool and cannot be easily manufactured. For this reason, Patent Document 1 uses a transfer film composed of a base material and a transfer part in which a non-slip layer made of polyurethane resin and an adhesive resin layer are laminated, and the transfer part is provided on the gripping surface of the writing tool. It is described that an anti-slip process is applied to the gripping surface of the writing tool after transfer.

[Brush 1]
With reference to FIG. 1, the brush 1 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a perspective view of a writing instrument 1 according to an embodiment of the present invention. As shown in FIG. 1, the writing instrument 1 includes a writing tool body 10 and a transfer part 20 that is transferred to the writing tool body 10 and covers at least a part of the surface 10s of the writing tool body.

  In this specification, the term tool 1 is used as a concept that includes a writing tool including the illustrated pencil, a brush for applying cosmetics, chemicals, paints, and the like, and an applicator such as a brush. Therefore, the writing tool main body portion 10 refers to a shaft portion that functions as a writing portion or an application portion. The same elements are denoted by the same reference numerals throughout the specification.

  The transfer unit 20 is provided so as to cover the entire surface 10s or part of the surface 10s of the writing tool main body. The transfer unit 20 includes a non-slip rubber layer 22 on the surface 20 s of the transfer unit on the non-contact surface side of the writing tool body unit 10.

It may be. When there are a plurality of rubber layer pattern portions 22a, a pattern can be given to the surface 20s of the transfer portion, that is, the gripping surface of the writing instrument 1. The writing tool 1 is formed by transferring the transfer part 20 to the writing tool main body part 10 using a writing film for writing tool 2 described later.

[Transfer film 2 for writing tools]
With reference to FIG. 2 and FIG. 3, the transfer film 2 for brushes of this embodiment is demonstrated. FIG. 2 is a plan view of the transfer film 2 for a brush according to the embodiment of the present invention, and FIG. 3 is a cross-sectional view taken along the line XX ′ of FIG. The transfer film 2 for writing tools is provided with the transfer part 20 and the peeling part 30 by the side of the anti-slip rubber layer to which the transfer part 20 was fixed. The transfer unit 20 is provided between the anti-slip rubber layer 22, the adhesive resin layer 28 disposed to face the anti-slip rubber layer 22, and the anti-slip rubber layer 22 and the adhesive resin layer 28. And an organic solvent impermeable resin layer 26 that blocks passage of the organic solvent from the side of the conductive resin layer 28 to the side of the anti-slip rubber layer 22.

  Thereby, the transfer film 2 for a brush of the present invention can easily form a non-slip on the gripping surface of the brush 1, and can be formed with an organic solvent or an adhesive contained in the forming material of the adhesive resin layer 28 at the time of manufacture. The organic solvent remaining in the conductive resin layer 28 hardly causes wrinkles, whitening, and partial peeling on the anti-slip rubber layer 22, and can be accurately transferred to the writing tool 1. That is, by containing the organic solvent impermeable resin layer 26 that blocks the passage of the organic solvent from the adhesive resin layer 28 side to the anti-slip rubber layer 22 side, the thin-film anti-slip rubber layer 22 swells. Is suppressed, and generation of wrinkles, whitening, and partial peeling is suppressed in the anti-slip rubber layer 22.

  The transfer portion 20 is fixed to the front surface 10s of the writing tool main body portion by an adhesive resin layer 28 contained on the back surface 20b side of the transfer portion. The thickness of the transfer part 20 can be 10 μm or more and 35 μm or less. As a result, the transfer unit 20 is sufficiently imparted with a non-slip function to the writing tool 1, and can suppress a decrease in the adhesion of the transfer unit 20 or a variation in the transfer pressure of the transfer unit 20.

  The organic solvent impermeable resin layer 26 is provided between the adhesive resin layer 28 and the anti-slip rubber layer 22 and allows the organic solvent to pass from the adhesive resin layer 28 side to the anti-slip rubber layer 22 side. This is a resin layer to be blocked. The organic solvent impermeable resin layer 26 is a layer containing a resin as a main component. The organic solvent impermeable resin layer 26 is preferably provided in contact with at least a part of the anti-slip rubber layer 22. This is because the influence of the organic solvent on the anti-slip rubber layer 22 can be reduced more effectively. The organic solvent impermeable resin layer 26 is preferably provided over the entire surface between the adhesive resin layer 28 and the anti-slip rubber layer 22.

  The material of the organic solvent-impermeable resin layer 26 differs depending on the type of organic solvent. For example, a thermosetting resin, an ultraviolet curable resin, an electron beam curable resin, a radiation curable resin that is cured by a curing process. It may contain a resin or the like as a main component. In particular, the organic solvent impermeable resin layer 26 can contain an ultraviolet curable resin as a main component and no organic solvent. As a result, the influence of the organic solvent on the anti-slip rubber layer 22 is further reduced, and the organic solvent-impermeable resin layer 26 is formed in a short time, and the influence on the other layers due to the curing treatment can be reduced. is there. The organic solvent-impermeable resin layer 26 is made of an adhesive resin layer 28 or an adhesive resin layer 28 or the adhesive resin layer 28 or the adhesive property of the organic solvent-impermeable resin layer 26 with respect to the organic solvent contained in the adhesive resin material. The anti-slip rubber layer 22 with respect to the organic solvent contained in the resin material is selected so as to have higher swelling resistance. For example, when the organic solvent contains a hydrocarbon solvent such as toluene or hexane, an ester solvent, or a ketone solvent in the adhesive resin layer 28 or the adhesive resin material, the organic solvent impermeable resin layer 26 is , Urethane acrylate monomer polymer, urethane acrylate oligomer polymer, polyfunctional acrylate monomer polymer, polyfunctional acrylate oligomer polymer, epoxy acrylate monomer polymer, epoxy acrylate oligomer polymer, polyester acrylate monomer polymer The polymer may contain at least one selected from the group consisting of polymers of polyester acrylate oligomers.

  The surface 26s of the organic solvent impermeable resin layer may be roughened, and the adhesive resin layer 28 may be provided in contact with the surface 26s of the organic solvent impermeable resin layer. As the organic solvent resistance of the organic solvent impermeable resin layer 26 increases, the adhesion between the organic solvent impermeable resin layer 26 and the adhesive resin layer 28 decreases. For this reason, the roughening as described above suppresses a decrease in adhesion between the organic solvent impermeable resin layer 26 and the adhesive resin layer 28, and the organic solvent that becomes a part of the transfer portion 20. The adhesion between the impermeable resin layer 26 and the adhesive resin layer 28 is enhanced. As a result, the surface roughness of the surface 26s of the organic solvent impermeable resin layer may be formed to be larger than the surface roughness of the back surface 26b facing the surface 26s of the organic solvent impermeable resin layer.

  The anti-slip rubber layer 22 is a layer that functions as an anti-slip of the gripping surface of the writing tool 1. The non-slip rubber layer 22 is made of natural rubber, isoprene rubber, butadiene rubber, styrene rubber, butyl rubber, ethylene propylene rubber, chloroprene rubber, epichlorohydrin rubber, nitrile rubber, acrylic rubber, urethane rubber, polysulfide rubber, silicone rubber, fluorine. It contains at least one selected from the group consisting of known rubber materials such as rubber. In order to prevent blocking, the anti-slip rubber layer 22 can contain a blocking agent.

  When the writing tool transfer film 2 is a writing tool transfer film that is transferred to a gripping surface of a writing tool such as a pencil, the thickness of the anti-slip rubber layer 22 can be set to 0.5 μm or more and 20 μm or less. Thereby, while being able to fully provide the anti-slip | skid function to the holding surface of a writing instrument, generation | occurrence | production of the nonuniformity of the non-slip | skid rubber layer 22 can be suppressed. When such a thin-film anti-slip rubber layer 22 is swollen by an organic solvent contained in the adhesive resin layer 28, wrinkles, whitening, and partial peeling tend to occur. For this reason, according to the present invention, wrinkles, whitening and partial peeling of the transfer film for writing instruments are effectively suppressed, and the transfer portion 20 can be accurately transferred to the writing instrument 1.

  The anti-slip rubber layer 22 may have a plurality of rubber layer pattern portions 22a formed in a pattern on the surface. For example, as shown in FIG. 2, the anti-slip rubber layer 22 may have a plurality of dot-shaped rubber layer pattern portions 22a arranged in a staggered manner. FIG. 6 shows a plan view of the transfer film for a brush 2a, 2b according to a modification of the embodiment of the present invention. As shown in FIG. The rubber layer 22 may have a plurality of strip-shaped rubber layer protrusions 22c arranged in parallel. As shown in FIG. 6A, the transfer film 2a for a brush may not have the rubber layer pattern portion 22a but may have only the rubber layer base portion 22b.

  The anti-slip rubber layer 22 may contain an ultraviolet curable rubber as a main component. As a result, the anti-slip rubber layer 22 can be formed thick, and the anti-slip function can be sufficiently imparted to the writing tool 1, and wrinkles, whitening, and partial peeling can occur in the anti-slip rubber layer 22. It can be further suppressed.

  The adhesive resin layer 28 is formed by applying an adhesive resin material containing a transfer adhesive resin and an organic solvent, and then performing at least one of drying, cooling, and curing as necessary. . The curing treatment is performed on curable coatings such as thermosetting resins, ultraviolet curable resins, electron beam curable resins, and radiation curable resins. The adhesive resin layer 28 may contain a remaining organic solvent. The thickness of the adhesive resin layer 28 can be in the range of 0.1 μm to 5 μm.

  Examples of transfer adhesive resins include acrylic resins, vinyl chloride resins, vinyl acetate resins, vinyl chloride-vinyl acetate copolymer resins, styrene-acrylic copolymer resins, polyester resins, polyamide resins, epoxy resins, isocyanates. 1 type or 2 types selected from the group consisting of epoxy resins, silicone resins, styrene-butadiene resins, ethylene-vinyl acetate resins, polyester resins, chlorinated rubber resins, chlorinated polypropylene resins, and urethane resins What consists of the above can be illustrated.

  Examples of organic solvents include ester solvents such as ethyl acetate, butyl acetate, and cellosolve acetate, alcohol solvents such as ethyl alcohol, isopropyl alcohol, and butyl alcohol; aromatic hydrocarbon solvents such as toluene and xylene; hexane Aliphatic hydrocarbon solvents such as methylene chloride, chloroform, trichloroethylene and trichloroethane; acetate solvents such as cellosolve acetate and methoxyacetate; acetone, N-methylpyrrolidone and methyl ethyl ketone Examples thereof include one or two or more selected from the group consisting of ketone solvents such as cyclohexanone and aprotic solvents such as dioxane and tetrahydrofuran. The adhesive resin material may contain additives such as thickeners, plasticizers, pigments, dyes, film forming agents, auxiliaries and the like.

  The combination of the organic solvent contained in the adhesive resin layer 28 or the adhesive resin material, the anti-slip rubber layer 22 and the organic solvent impermeable resin layer 26 is a combination of the organic solvent contained in the adhesive resin layer 28 or the adhesive resin material. It differs depending on the type and the material of the organic solvent impermeable resin layer 26 and the anti-slip rubber layer 22. In addition, the lower the swelling resistance of the anti-slip rubber layer 22 with respect to the organic solvent contained in the adhesive resin layer 28 or the adhesive resin material, the greater the effect of the organic solvent impermeable resin layer 26. For example, when the non-slip rubber layer 22 contains at least one of isoprene rubber and butadiene rubber, the organic solvent contained in the adhesive resin layer 28 is toluene, hexane, isooctane, isopropyl ether, benzyl benzoate, ethylbenzene, epichlorohydrin, xylene. , Kerosene, mineral oil, acetic acid, acetate, diisopropyl ketone, cyclohexanol, cyclohexane, diethyl ether, cellosolve, tetrahydrofuran, tetrachloroethane, tetralin, hexane, pyridine, etc. And the peeling suppression effect becomes large. In this case, the organic solvent impermeable resin layer 26 includes a polymer of urethane acrylate monomer, a polymer of urethane acrylate oligomer, a polymer of polyfunctional acrylate monomer, a polymer of polyfunctional acrylate oligomer, a polymer of epoxy acrylate monomer, It may contain at least one selected from the group consisting of a polymer of an epoxy acrylate oligomer, a polymer of a polyester acrylate monomer, and a polymer of a polyester acrylate oligomer.

  For example, when the anti-slip rubber layer 22 contains at least one of isoprene rubber and butadiene rubber, the organic solvent contained in the adhesive resin layer 28 is acetophenone, acetone, isooctane, isopropyl ether, ethylbenzene, epichlorohydrin, xylene, kerosene. Mineral oil, acetic acid, acetic acid ester, diisopropyl ketone, diethyl ether, cellosolve, dioxane, phenol, hexane, pyridine, and the like increase the effect of suppressing appearance defects and preventing peeling by the organic solvent impermeable resin layer 26. Also in this case, the organic solvent impermeable resin layer 26 is composed of a urethane acrylate monomer polymer, a urethane acrylate oligomer polymer, a polyfunctional acrylate monomer polymer, a polyfunctional acrylate oligomer polymer, and an epoxy acrylate monomer polymer. And at least one selected from the group consisting of a polymer of an epoxy acrylate oligomer, a polymer of a polyester acrylate monomer, and a polymer of a polyester acrylate oligomer.

  Furthermore, for example, when the anti-slip rubber layer 22 contains butyl rubber, the organic solvent contained in the adhesive resin layer 28 is acetone, isooctane, isopropyl ether, ethylbenzene, xylene, kerosene, mineral oil, acetic acid, fatty acid, diisopropyl ketone, When it is diethyl ether, dioxane, hexane, or the like, the effect of suppressing the appearance defect and the peeling prevention by the organic solvent impermeable resin layer 26 are increased. Also in this case, the organic solvent impermeable resin layer 26 is composed of a urethane acrylate monomer polymer, a urethane acrylate oligomer polymer, a polyfunctional acrylate monomer polymer, a polyfunctional acrylate oligomer polymer, and an epoxy acrylate monomer polymer. And at least one selected from the group consisting of a polymer of an epoxy acrylate oligomer, a polymer of a polyester acrylate monomer, and a polymer of a polyester acrylate oligomer.

  The peeling portion 30 on the non-slip rubber layer side contains a base material sheet that is detachably provided on the transfer portion 20. As will be described later, the non-slip rubber layer side peeling portion 30 is removed from the transfer portion 20 either before or after the step of fixing the transfer portion 20 to the surface 10s of the writing tool body portion or simultaneously with the fixing step. Is. The thickness of the peeling portion 30 on the non-slip rubber layer side can be 6 μm or more and 200 μm or less. The peeling portion 30 on the non-slip rubber layer side may be provided with the same outer shape as that of the transfer portion 20, or may be provided with an outer shape larger than the outer shape of the transfer portion 20, as shown in FIG. The transfer film 2e for writing tools is a laminate of a plurality of transfer parts 20 and a peeling part 30 on the anti-slip rubber layer side. As shown in FIG. 7, when the outer shape is larger than the outer shape of the transfer unit 20, the peeling unit 30 on the anti-slip rubber layer side can be more easily peeled off, and a plurality of transfer units 20 can be easily conveyed. can do.

  A flexible base sheet can be used for the base sheet. For example, as the flexible base sheet, a polyester film such as polyethylene terephthalate, a polyolefin film such as polypropylene, a plastic film such as polycarbonate, polyamide, or polyimide, a release paper such as glassine paper or paraffin paper can be used. The peeling portion 30 on the non-slip rubber layer side may include a base sheet and a release layer formed on the surface 30s on which the transfer portion 20 of the base sheet is provided. It may consist only of a material sheet. The release layer can be provided when the transfer layer is not sufficiently releasable at the time of transfer. Examples of the release agent applied to the base sheet for forming the release layer include waxes, silicones. One or more of wax, silicone resin, fluororesin, acrylic resin, polyvinyl alcohol and the like can be selected and used.

  Note that the peeling portion 30 on the anti-slip rubber layer side may include an organic solvent impermeable material as a main component. According to this, in the case where a plurality of the transfer films 2 for the writing tool are included by winding the transfer film 2 for the writing tools in a roll shape or by laminating them in a single sheet shape, the adhesion of the adjacent transfer film 2 for the writing tool It is possible to suppress the occurrence of defects in appearance due to swelling of the anti-slip rubber layer 22 by the organic solvent from the conductive resin layer 28.

  Moreover, the peeling part 30 by the side of a non-slip | skid rubber layer may consist of a translucent member. As a result, when the anti-slip rubber layer 22 contains an ultraviolet curable rubber, the anti-slip rubber layer 22 can be irradiated with ultraviolet rays via the peeling portion 30 on the anti-slip rubber layer side, and the non-slip rubber layer 22 is not applied to the transport device or the like. The anti-slip rubber layer 22 can be formed without adhesion of the cured ultraviolet curable rubber material.

  Furthermore, although not shown in the drawing, the transfer film 2 for a brush may include other layers such as a primer layer for improving adhesion between the layers and a decoration layer for adding decorativeness between the layers. Needless to say.

Layer 22 is formed.

  The one manufacturing method further includes a step of forming an organic solvent impermeable resin layer 26 above the anti-slip rubber layer 22. In the step of forming the organic solvent impermeable resin layer 26, after applying the non-slip rubber layer forming material by a known coating method, if necessary, curing treatment is performed by irradiating with ultraviolet rays, drying, or the like. A transparent resin layer 26 is formed.

  In the above one manufacturing method, further, the organic solvent impermeable resin layer 26 prevents the permeation from the adhesive resin layer side to the non-slip rubber layer side above the organic solvent impermeable resin layer 26, thereby preventing the slip. A step of forming the adhesive resin layer 28 with an adhesive resin material containing an organic solvent capable of swelling the rubber layer 22 is provided. In the step of forming the adhesive resin layer 28, after applying the non-slip rubber layer forming material by a known application method, if necessary, the adhesive resin is subjected to at least one of drying, cooling or curing treatment. Layer 28 is formed.

  Thereby, in the formation process of the adhesive resin layer 28, since the non-slip rubber layer 22 can be covered and protected by the organic solvent impermeable resin layer 26, wrinkles, whitening, and partial peeling of the transfer film 2 for writing tools can be prevented. It can be made more difficult to occur.

  In addition, after the formation process of the organic solvent impermeable resin layer 26 and before the formation process of the adhesive resin layer 28, a roughening process for roughening the surface 26s of the organic solvent impermeable resin layer may be provided. . In the roughening step, the surface 26s of the organic solvent impermeable resin layer is coated with a mud varnish to laminate the roughened layer, or the surface 26s of the organic solvent impermeable resin layer is subjected to a corona discharge treatment.

The adhesive resin layer 28 is formed by applying an anti-slip rubber layer forming material by a known application method and then performing drying, cooling, or curing treatment, if necessary, by performing at least one of drying, cooling, and curing treatment. Layer 28 is formed.

  The other manufacturing method further includes a step of forming an organic solvent impermeable resin layer 26 that blocks the passage of the organic solvent above the adhesive resin layer 28. The organic solvent-impermeable resin layer 26 is formed by applying a non-slip rubber layer forming material by a known application method and then performing drying, cooling or curing treatment, if necessary. An organic solvent impermeable resin layer 26 is formed.

  The other manufacturing method further includes a step of forming an anti-slip rubber layer 22 above the organic solvent impermeable resin layer 26. The formation process of the non-slip rubber layer 22 and the formation process of the peeling portion 30 can be performed in one stage. After applying the anti-slip rubber layer forming material by a known application method, the coating film of the anti-slip rubber layer forming material A non-slip rubber layer 22 and the peeling portion 30 are formed by placing a base sheet or the like that becomes the peeling portion 30 above the substrate and performing at least one of drying, cooling, or curing treatment if necessary. . The peelable substrate may be left as it is and used as the peelable portion 32 on the adhesive resin layer side, or may be peeled off to expose the adhesive resin layer 28.
